**** BEGIN LOGGING AT Fri May 22 02:59:57 2020
May 22 14:30:37 <zmatt> I'm puzzled why ken thinks I'd have any interest in that
May 22 14:31:36 <mru> I'm just puzzled
May 22 14:33:27 <zmatt> I'm also puzzled by this: https://github.com/SiliconLabs/wfx-fullMAC-tools/blob/master/Examples/SiliconLabs/commissioning/micrium_os/SLSTK3701A/src/lwip_micriumos.c#L77-L129
May 22 14:35:50 <mru> typical ugly vendor code
May 22 15:27:36 <thinkfat> note to self: don't run ntpd on a machine that is a ptp slave
May 22 16:13:27 <zmatt> thinkfat: we keep ptp entirely separate from the system time
May 22 16:14:21 <zmatt> (as a service which publishes the information needed by applications that want to translate between PTP time and raw monotonic time)
May 22 16:46:18 <thinkfat> oh, so you only run ptp4l and not phc2sys?
May 22 16:49:24 <zmatt> a customized ptp4l since iirc the normal one still wants to modify global stuff for some reason
May 22 16:51:07 <zmatt> I honestly don't completely get the way ptp normally works on linux, in the sense that cpts timestamps are translated into some custom timebase whose frequency can be changed by (appropriately privileged) userspace, which completely puzzles me since that makes the timestamps impossible to compare with anything else
May 22 16:51:24 <zmatt> instead I've made sure that this timebase is always equal to raw monotonic time
May 22 16:52:28 <zmatt> so our ptpd gets packet timestamps in raw monotonic time, and can thus determine (and publish) the relationship between raw monotonic time and ptp time
May 22 16:53:11 <zmatt> and since our audio timestamps are also in raw monotonic time, that allows translation between audio stream index and ptp time
May 22 16:53:24 <zmatt> thus allowing network synchronziation of audio
May 22 18:24:35 <thinkfat> which makes sense anyway, no need for a UTC synced time
May 22 18:45:57 <zmatt> correct, the needs for system time and ptp time are quite different:  for ptp (at least in our case) all that matters is that everything on the network agrees on it, while for system time I care a lot more about monotonicity
May 22 19:03:50 <thinkfat> so effectively you only sync the phc's of all the devices
May 22 19:08:52 <zmatt> what's "phc" ?
May 22 19:09:25 <thinkfat> the clock ptp lives off of, iirc
May 22 19:10:01 <thinkfat> "phc" = "ptp hardware clock"
May 22 19:10:06 <thinkfat> whatever that means
May 22 19:10:08 <zmatt> no
May 22 19:10:21 <zmatt> that's the thing I just mentioned I don't understand
May 22 19:11:15 <zmatt> at least, I assume that's what they mean by it
May 22 19:13:54 <zmatt> we don't adjust anything in hardware or kernel
May 22 19:17:07 <zmatt> the ptp clock is just embodied in a triple of { reference point in ptp time, reference point in raw monotonic time, frequency ratio ptp time / raw monotonic time }
May 22 19:17:29 <zmatt> maintained in userspace and published via dbus
May 22 20:29:04 <thinkfat> zmatt: I'm looking at your cpts patches, looks like the hw timestamping support is available in the current TI kernel, but slightly different than what you do
May 22 20:30:02 <thinkfat> or did
May 22 20:30:24 <zmatt> my patches are mostly bugfixes iirc
May 22 20:31:15 <thinkfat> well one initializes the cpts timer to the monotonic time instead of kernel real time, that is not a bugfix
May 22 20:31:28 <zmatt> initializing it to realtime is silly, it won't stay in sync with it
May 22 20:32:12 <thinkfat> hm.. indeed.
May 22 20:32:48 <zmatt> if you use a system clocksource those frequency divides 1 GHz (to avoid raw monotonic time drift due to fixed-point rounding error) then the ptp clock is frequency-locked to the raw monotonic time
May 22 20:32:55 <zmatt> *whose frequency
May 22 20:33:01 <zmatt> that's why I implemented the eCAP clocksource driver
May 22 20:33:35 <zmatt> so then, if you initialize it to be in sync with raw monotonic time, it will stay in sync with raw monotonic time
May 22 20:33:59 <thinkfat> so that change makes most sense if you use the ecap clocksource?
May 22 20:34:25 <zmatt> yeah, that's something I discovered later when we noticed the system time was slowly drifting away
May 22 20:34:32 <zmatt> and then I implemented the eCAP clocksource to fix it
May 22 20:45:46 <henk> the /topic has a link to https://beagleboard.org/boot which seems like an empty page to me. Can anyone check and confirm if it’s really empty or a problem on my side?
May 22 20:47:06 <mru> henk: it redirects to http://ahsoftware.de/Beaglebone_Black_Boot_explained.svg
May 22 20:47:08 <zmatt> yeah http://bbb.io/boot is indeed just a blank page
May 22 20:48:08 <zmatt> mru: uhh, not for me
May 22 20:48:45 <mru> apparently the redirect is done with javascript
May 22 20:48:48 <henk> mru: oh, in a new tab … didn’t notice that on the first attempt because I clicked ALL THE LINKS (and I have way too many tabs open to notice that another one opened)
May 22 20:49:08 <mru> I didn't get any extra tabs
May 22 20:49:14 <zmatt> mru: well it doesn't work here, and I don't have javascript disabled
May 22 20:49:21 <zmatt> no error in console either
May 22 20:49:57 <henk> mru: yeah, I just realized that it’s probably due to the "temporary containers" extension in my browser …
May 22 20:50:04 <henk> mru, zmatt: thanks for checking
May 22 20:50:35 <zmatt> thinkfat: I just committed whatever uncommitted changes I still had sitting around.... https://github.com/dutchanddutch/bb-kernel/blob/am33x-v4.14/patches/local/0018-XXX-misc-cpts-stuff.patch
May 22 20:50:58 <zmatt> thinkfat: I honestly can't remember what I was doing, other than that I was debugging some issue
May 22 20:51:49 <thinkfat> I'm having a look
May 22 20:52:12 <thinkfat> though most of the cpts patches don't apply (any more?) to the 4.19 TI kernel
May 22 20:52:31 <zmatt> yeah I really need to work on moving to 4.19
May 22 20:52:46 <thinkfat> it's what the current images are using...
May 22 20:52:49 <zmatt> it just hasn't been a priority
May 22 20:53:00 <mru> over here we're working on moving _away_ from 4.19
May 22 20:53:07 <zmatt> to?
May 22 20:53:18 <mru> 5.4, unless a new lts comes out before we make it
May 22 20:53:49 <thinkfat> 4.19, I sort of expect it to get a lifetime extension
May 22 20:54:16 <mru> we've accumulated more patches and backports than I like on 4.19
May 22 20:54:28 <zmatt> I guess I could try skipping 4.19 and go straight to 5.4
May 22 20:54:39 <zmatt> but dunno if that's a good idea
May 22 20:55:35 <ds2> mru?
May 22 20:55:49 <mru> ds2: !
May 22 20:56:06 <ds2> u have surfaced?
May 22 20:56:19 <zmatt> I should probably at least try to port/rewrite my cpts bugfixes to mainline and submit them upstream
May 22 20:56:46 <zmatt> but there's plenty of things I "should probably dp"
May 22 20:57:04 <zmatt> in addition to things that actually have my priority :/
May 22 20:59:32 <thinkfat> they'd still make sense...
May 22 21:00:19 <zmatt> I mean, unless cpts magically stopped sucking somewhere between 4.14 and latest mainline
May 22 21:02:44 * av500 is not sure about surfacing, uses a snorkel
May 22 21:02:58 <ds2> hey av500
May 22 21:03:04 <av500> -ETOOLATE
May 22 21:03:06 <av500> hi :)
May 22 21:03:30 <av500> this will not end well
May 22 21:04:02 * ds2 looks for the tardis
May 22 21:05:20 <thinkfat> av500: ya should have stayed at periscope depth for a while ;)
May 22 21:06:41 <thinkfat> zmatt: I'm trying to debug some oddball effects I see with the ptp "master offset"
May 22 21:07:42 <zmatt> ?
May 22 21:07:43 <thinkfat> zmatt: slave is mostly in between +/- 300ns, but now and then it gets a huge kick and finds itself 40µs or so off
May 22 21:08:05 <zmatt> that's not good
May 22 21:08:08 <thinkfat> yep
May 22 21:08:24 <zmatt> though not terrible either I guess
May 22 21:08:43 <zmatt> sounds like that could easily be caused by network traffic
May 22 21:08:44 <thinkfat> and then I see a lot of oscillation until it settles back into +/- 300ns
May 22 21:09:03 <zmatt> poorly working outlier-filter I guess?
May 22 21:09:37 <thinkfat> might be, broken timestamps from the master maybe...
May 22 21:09:55 <thinkfat> hence my looking into your cpts patches.
May 22 21:09:58 <zmatt> that sounds less likely
May 22 21:10:19 <zmatt> far less likely in fact
May 22 21:11:08 <mru> when the impossible has been eliminated...
May 22 21:11:37 <av500> the possible has to be laminated...
May 22 21:11:43 <thinkfat> mru: I'm far from having eliminated all other possibilities
May 22 21:11:52 <zmatt> no the most likely explanation is packet delay, and it doesn't sound like that's been eliminated
May 22 21:11:55 <thinkfat> mru: I'm at the "poking with a stick" stage right now
May 22 21:12:23 <thinkfat> zmatt: no, indeed not.
May 22 21:12:41 <zmatt> if you want to eliminate that, get an AVB switch :P
May 22 21:13:03 <thinkfat> zmatt: I have a very basic 5 port tp-link desktop switch at the moment ;)
May 22 21:13:45 <thinkfat> zmatt: you say, outlier filter, hm?
May 22 21:14:02 <zmatt> I mean, I'd hope ptp4l has one :P
May 22 21:14:07 <mru> yes, filter out the lies
May 22 21:14:09 <zmatt> but I haven't really studied the code at all
May 22 21:14:16 * zmatt slaps mru with a trout
May 22 21:14:24 <av500> a trump?
May 22 21:15:19 <zmatt> thinkfat: dealing with noise/jitter in data is not simple, unfortunately
May 22 21:16:31 <thinkfat> zmatt: looks like there's a moving median filter
May 22 21:16:41 <thinkfat> zmatt: which is not so bad for detecting outliers
May 22 21:17:11 <thinkfat> compared to the moving average that was there before
May 22 21:17:26 <zmatt> indeed
May 22 21:37:30 <zmatt> ew, who are these people who post comments like these... https://twitter.com/mischacrossing/status/1226961792745775105
May 22 22:14:43 <set_> @zmatt: What made you find that twitter feed?
May 22 22:15:56 <set_> I watched every fatality in Mortal Kombat for some reason today. I need no more ools and gools.
May 22 22:15:58 <set_> Ha.
May 22 22:16:31 <zmatt> set_: someone linked to it
May 22 22:16:36 <set_> Oh.
May 22 22:16:45 <zmatt> (the tweet, haven't looked at the feed)
May 22 22:17:00 <set_> Oops. I figured I would share since I thought you shared.
May 22 22:17:04 <set_> Dang. Fooled again!
May 22 22:17:55 <GenTooMan> Sic et Nauseum well that's nice... met those kind of ... people of the opposite sex. I normally find a nice spot not near them.
May 22 22:19:11 <set_> Yea. It is a bit weird to deal w/ shallow minded individuals at times. Luckily, there are more of them than me. Boo.
May 22 22:19:39 <set_> Hey!
May 22 22:20:25 <set_> Have you guys ever figured out the Virginia Flag's wording on it?
May 22 22:21:02 <set_> Hello?
May 22 22:22:19 <set_> Fine.
May 22 22:22:35 <GenTooMan> never bothered?
May 22 22:23:03 <GenTooMan> must take life maintaining meds.
May 22 22:27:23 <set_> Hello!
May 22 22:27:36 <set_> Oh me, yep. I get the hints.
May 22 22:27:58 <set_> "Thus always to Tyrants!"
May 22 22:28:34 <set_> GenTooMan: What does Sic et Nauseum mean?
May 22 22:29:19 <set_> I think it is the only flag w/ a stabbed man on it being held down by a foot of another person, fyi.
May 22 22:31:41 <set_> Ooh.
May 22 22:33:28 <set_> Anyway, forget all that. What would be the best way to make a file save on my BBGW for my file of video?
May 22 22:33:29 <set_> ...
May 22 22:33:43 <set_> Would a socket be better than just a regular .service?
May 22 22:56:33 <zmatt> that question makes no sense
May 22 22:56:57 <zmatt> they are different things that serve different purposes
May 22 23:01:27 <set_> Oh.
May 22 23:01:46 <set_> See, I read that I could save a file w/ a socket.
May 22 23:01:54 <zmatt> ??
May 22 23:02:04 <set_> Sorry. In python.
May 22 23:02:10 <set_> import socket
May 22 23:02:33 <set_> So, here I am trying these ideas online.
May 22 23:02:36 <zmatt> ?
May 22 23:02:42 <set_> What?
May 22 23:03:06 <zmatt> what are you talking about?  you just seem to be stringing random words together
May 22 23:03:12 <zmatt> "save a file with a socket" ?  what?
May 22 23:03:25 <set_> Hahha. Okay. Let me try to make more sense.
May 22 23:04:15 <set_> I have a python file so far w/ a client but i was going to use my older python file as the server.
May 22 23:04:50 <set_> Now...
May 22 23:05:26 <set_> The two python files cannot "talk" to each other so far (hence, no file saving). But...
May 22 23:05:36 <zmatt> ??
May 22 23:05:57 <set_> The client does not accept my video reference online.
May 22 23:06:23 <zmatt> you know, I'm sorry I asked
May 22 23:06:26 <set_> Ha.
May 22 23:06:30 <zmatt> you can stop trying to explain now
May 22 23:06:31 <set_> Fine.
May 22 23:06:34 <set_> Okay.
May 22 23:06:53 <zmatt> meanwhile I'll try to find some earplugs to stop my brain from leaking out
May 22 23:07:01 <zmatt> afk
May 22 23:07:10 <set_> I am going to make it work. Just you wait!
May 22 23:07:30 <set_> Every time @zmatt types "afk," I think of Alf.
May 22 23:29:55 <GenTooMan> I don't remember watching Alf
May 22 23:32:54 <set_> It was good.
May 22 23:33:25 <MattB0ne> ok
May 22 23:33:26 <MattB0ne> people
May 22 23:33:40 <MattB0ne> is it me or are boards you get off the internet cheaply made
May 22 23:33:50 <MattB0ne> i do not understand what I got here
May 22 23:35:54 <zmatt> I'm sure the internet has both well-made boards and cheaply-made boards to offer :P
May 22 23:35:56 <MattB0ne> https://ibb.co/zPj8HbW
May 22 23:36:24 <MattB0ne> if I need too wire power to both sides, so a total of 8 connections
May 22 23:36:31 <zmatt> what is it?
May 22 23:36:32 <MattB0ne> why are two of the holes filled
May 22 23:36:53 <MattB0ne> on each side
May 22 23:37:31 <zmatt> check documentation?
May 22 23:37:32 <MattB0ne> am I missing something
May 22 23:38:14 <zmatt> what you're missing, so far, is an explanation of what we're even looking at
May 22 23:38:57 <zmatt> say, a datasheet or a product page
May 22 23:40:08 <MattB0ne> http://www.hiletgo.com/ProductDetail/3433372.html
May 22 23:41:27 <MattB0ne> I am not sure how to wire
May 22 23:41:30 <MattB0ne> up to it
May 22 23:41:41 <MattB0ne> do I melt the holes so I can put my header in
May 22 23:41:52 <MattB0ne> or do I just try and solder the wire right onto the pad
May 22 23:41:52 <zmatt> I mean, why did you buy such an unintelligible board?
May 22 23:42:02 <zmatt> they have high-res photos to go with the weird instructions
May 22 23:42:10 <zmatt> that didn't make alarm bells go off for you?
May 22 23:42:16 <MattB0ne> because I am a noob who doesn't know what I am doing
May 22 23:42:31 <MattB0ne> they suck
May 22 23:42:38 <MattB0ne> i will look for another company
May 22 23:42:40 <zmatt> but you could look at the photos and read the instructions and wonder "hmm, how would I wire this up?" before buying it
May 22 23:43:06 <MattB0ne> noted
May 22 23:43:28 <zmatt> and I'd not buy a board like this without a schematic
May 22 23:43:52 <zmatt> let alone one whose only documentation is a single paragraph in incoherent english
May 22 23:43:59 <MattB0ne> are there any brands that generally are pretty good
May 22 23:44:32 <MattB0ne> like you know DeWalt makes decent tools
May 22 23:44:43 <MattB0ne> the electronics equivalent
May 22 23:44:57 <MattB0ne> they all look the same when I search for MAX3232
May 22 23:46:20 <zmatt> https://www.sparkfun.com/products/11189   this at least has a pdf schematic and a github repo of the original design files
May 22 23:48:23 <zmatt> and you can solder on a normal header (although honestly only the fourth photo make it clear that it has holes to mount a connector, on the other ones they looked more like surface-mount pads, but that just seems to be poor photography)
May 22 23:49:08 <zmatt> and it has very excellent labeling on the bottom side
May 22 23:56:11 <MattB0ne> if you have surface mount pads is there a way to convert to holes?
May 22 23:56:23 <MattB0ne> I think what I have are two holes two surface mounts on each side
May 22 23:56:42 <MattB0ne> two tiny ass surface mount pads
May 22 23:57:26 <zmatt> honestly with your thing I can't even tell which side is low-voltage (transmitter input / receiver output) and which side is RS232 (transmitter output / receiver input)
May 22 23:58:21 <MattB0ne> the back is labeled post ing now
May 22 23:58:55 <zmatt> oh I see now
May 22 23:59:06 <MattB0ne> https://ibb.co/vjC9wDV
May 22 23:59:14 <MattB0ne> this seems hard to work with
May 22 23:59:29 <MattB0ne> I want to have just 4 female headers to this thing
May 22 23:59:40 <MattB0ne> since I need to use jumpers with the BBB
May 22 23:59:50 <zmatt> yep, looks pretty awkward, wouldn't have bought it myself :P
May 23 00:00:07 <zmatt> but it's also something you could have determined prior to buying it
May 23 00:00:26 <zmatt> simply by looking before buying
May 23 00:00:31 <MattB0ne> sigh
May 23 00:00:41 <MattB0ne> so I just want thick soldering pads
May 23 00:00:59 <zmatt> i.e. you want something like that sparkfun one
May 23 00:02:40 <zmatt> https://cdn.sparkfun.com//assets/parts/6/7/3/8/11189-01a.jpg   you can simply solder a 10-pin header onto that
May 23 00:03:49 <zmatt> maybe you can find a similar but cheaper one somewhere
May 23 00:04:28 <zmatt> (although, if you buy the cheapest you can find, you lose the right to complain if it turns out cheaply-made :P )
May 23 00:07:56 <MattB0ne> a lot cheap junk out there
May 23 00:09:22 <MattB0ne> with the sprak fun one I can only supply one power source but with the others I can power both sides
May 23 00:09:43 <MattB0ne> if I only use the 3.3V from the BBB will that be enough to talk to a RS232 port
May 23 00:10:12 <MattB0ne> with the other chips I can power from the board which is 5V and still use the 3.3V for the TTL side for the BBB
May 23 00:10:16 <zmatt> nono, the incoherent paragraph of the weird board you got explained the two "power" sides are simply connected to each other
May 23 00:10:28 <zmatt> the max3232 has only one power supply input
May 23 00:11:10 <zmatt> you can power the max3232 at any voltage between 3V and 5.5V, and this will also be your logic voltage
May 23 00:11:13 <MattB0ne> ok just need one power supply and it should be the BBB to protect the board
May 23 00:11:29 <zmatt> yes it should be powered by the 3.3V from the BBB
May 23 00:28:32 <set_> Hey!
May 23 00:28:43 <set_> You guys...
May 23 00:29:32 <set_> I figured out how to solve my issue. I can record, save, and almost perform playback.
May 23 00:30:03 <set_> It seems that my system does not currently have a .avi file player. Boo!
May 23 00:31:35 <set_> but...it is w/ cv2 and numpy.
May 23 00:42:24 <set_> I think the .avi file that is saved gets corrupted somehow in b/t the transfer from Linux to Windows. I might have to use tightvncserver.
May 23 00:46:05 <GenTooMan> mpv
May 23 00:46:11 <set_> I tried some cheap (free) .avi file players. All bogus. Anyway, I am going to just try Linux to play the .avi file now.
May 23 00:46:26 <GenTooMan> mpv or vlc
May 23 00:46:39 <set_> GenTooMan: mpv or vlc are video file types?
May 23 00:46:54 <GenTooMan> no video players
May 23 00:46:59 <set_> Oh. Okay.
May 23 00:47:15 <set_> VLC. I have heard the name or seen the "app" before today.
May 23 00:47:22 <set_> Okay. I can try ti.
May 23 00:47:25 <set_> it.
May 23 00:47:26 <GenTooMan> I use to have OGM and AVI but that's stuff from almost 20 years ago.
May 23 00:48:02 <set_> Oh. See. I do not think that I can use opencv2 w/ python3 for mp3 playback. I am not sure though.
May 23 00:49:40 <set_> GenTooMan: Man, I wish I had my BBB bot out and about today. I saw an egret kill a mouse, then a crow stole it, and then a Mississippi Kite showed up to try and steal it from the crow.
May 23 00:49:58 <set_> Fledged.
May 23 00:50:15 <set_> I could have gotten the bot close to see the action.
May 23 00:51:19 <set_> I know. Disgusting but life!
May 23 00:54:33 <GenTooMan> They were obviously hungryu
May 23 00:57:15 <set_> Yep.
May 23 00:57:32 <set_> Watching is half the battle.
May 23 00:58:41 <set_> Is saving and writing to a file easy w/ opencv2 w/ mp3 files or is that not negotiable on the BBGW?
May 23 00:59:48 <GenTooMan> no idea .. however if you want to use it you should look
May 23 01:00:19 <set_> mp4...sorry.
May 23 01:00:24 <set_> Okay.
May 23 01:04:02 <GenTooMan> yes their is a significant difference. by the way MP3 is actually Mpeg layer 3 not mpeg 3 they had to skip the third iterative number because everyone one called it MP3 fortunately AAC is called AAC
May 23 01:04:28 <set_> Right.
May 23 01:04:42 <set_> I just learned that idea from running the source I made.
May 23 01:05:58 <set_> ffmpeg had an issue w/ mp4 and i need to write the file of, this so-called mp4, as mpeg4 or at least mpeg3.
May 23 01:07:33 <GenTooMan> I've never had a problem with mp4 and ffmpeg ...
May 23 01:07:46 <set_> And that is b/c of?
May 23 01:07:47 <GenTooMan> I am using it as we speak in a python script
May 23 01:07:52 <set_> Nice!
May 23 01:07:56 <set_> Me too!
May 23 01:08:08 <GenTooMan> I've written 5 different python scripts to use ffmpeg MKV merge etc.
May 23 01:08:28 <set_> I got some of my source from a neat site, https://www.learnopencv.com/.
May 23 01:08:34 <set_> Ha.
May 23 01:08:43 <set_> Nice.
May 23 01:09:10 <set_> GenTooMan: I thought you did not use the cameras.
May 23 01:09:19 <GenTooMan> ffmpeg outputs very detailed error information I'm sure it told you exactly what was wrong.
May 23 01:09:19 <set_> Or was it, webcams?
May 23 01:09:26 <set_> yes.
May 23 01:09:30 <set_> It did.
May 23 01:09:45 <GenTooMan> EBKAC?
May 23 01:10:02 <set_> I was extremely satisfied w/ it telling me what happened and what it was doing instead.
May 23 01:13:05 <set_> ffmpeg was put on this board b/c of another source I installed.
May 23 01:13:12 <set_> I am glad it works as nice as it does.
May 23 01:14:01 <GenTooMan> well one issue that happens with ffmpeg is all the options aren't compiled and it won't encode or use a specific format. That's the only thing I can think of.
May 23 01:14:33 <set_> It told me that mp4 was not used and it was reverting back to mpeg3.
May 23 01:15:12 <GenTooMan> was it an mp4 file? that could have been H264
May 23 01:16:21 <set_> Let me check.
May 23 01:16:58 <GenTooMan> mp4 files are not per say MPEG 4 they are QuickTime format from Apple.
May 23 01:17:10 <set_> Oh.
May 23 01:17:12 <set_> Dang.
May 23 01:17:19 <set_> I need to change up some stuff then.
May 23 01:17:50 <GenTooMan> use media info to check the file
May 23 01:18:17 <set_> Like >>> media info <filename.mp4>?
May 23 01:18:19 <GenTooMan> if you have a script in python you can check it using the media info library.
May 23 01:18:29 <set_> I will look it up.
May 23 01:18:44 <GenTooMan> more like mediainfo
May 23 01:18:50 <set_> Oh.
May 23 01:18:51 <set_> Okay.
May 23 01:19:23 <GenTooMan> at the CLI you can do that. They python library is ... pymediainfo
May 23 01:19:29 <GenTooMan> the even\
May 23 01:20:18 <set_> I never once heard of this library. So, apt install python3-pymediainfo?
May 23 01:20:58 <set_> I got it.
May 23 01:21:00 <set_> Okay.
May 23 01:21:31 <GenTooMan> right FYI the easiest use is "from pymediainfo import MediaInfo"
May 23 01:21:53 <set_> Neat.
May 23 01:21:58 <set_> My file is mpeg-4.
May 23 01:22:17 <set_> 10 fps, ha.
May 23 01:22:42 <GenTooMan> you may need to match frame rates.
May 23 01:22:46 <set_> 8 bit depth.
May 23 01:22:59 <set_> Heh? How would one go about that idea?
May 23 01:23:56 <set_> 4MB about for only 12 sec. of video time.
May 23 01:23:58 <set_> Yikes.
May 23 01:23:58 <GenTooMan> Oh dear you are a neophyte to using ffmpeg THAT would be a big problem as ffmpeg is rather complicated lots and lots and lots of settings.
May 23 01:24:12 <set_> Yes. I am scared to test things.
May 23 01:24:46 <set_> I am trying to make these "puppies" last until the next noah's ark shows up.
May 23 01:24:50 <GenTooMan> well as long as you don't delete files you are ok
May 23 01:24:54 <set_> Ha.
May 23 01:25:25 <GenTooMan> are you streaming the video to your PC?
May 23 01:25:34 <set_> I am just learning about ffmpeg. I found a nice site where they...oh.
May 23 01:25:39 <set_> No. Not yet.
May 23 01:25:51 <set_> I was going to try but I have failed at it so far.
May 23 01:26:07 <set_> I cannot open the mpeg4 file on my BBGW.
May 23 01:26:17 <set_> I was going to test there first.
May 23 01:27:13 <set_> Man. I do not know the first thing about playing video on lInux.
May 23 01:28:05 <GenTooMan> copy it to your PC as your BBGW probably has an AM3358 which will be slow.
May 23 01:28:12 <set_> Hey.
May 23 01:28:20 <set_> I think it is b/c of the codec I am using.
May 23 01:28:54 <set_> I tried to copy the file to my pc. I have a win pc for now, I guess I can try something real quickly. Let me boot it up.
May 23 01:29:34 <GenTooMan> you should have an FTP server SSH and putty work fine as well. filezilla is great with SSH as well
May 23 01:29:56 <set_> I have WinSCP.
May 23 01:29:58 <set_> Does that count
May 23 01:30:15 <GenTooMan> use filezilla to move stuff it's MUCH easier.
May 23 01:30:35 <set_> Okay...
May 23 01:30:52 <set_> It will take me longer to set up Filezilla compared to booting this pc w/ Linux on it.
May 23 01:32:22 <GenTooMan> Well don't you have MinGW ? well anyone filezilla is the same on linux as it is on windows and the same with putty
May 23 01:33:58 <set_> I can use scp on Linux for the file.
May 23 01:34:39 <GenTooMan> Ok use what you are sure will work?
May 23 01:36:04 <set_> Too bad.
May 23 01:36:26 <set_> My new Debian Distro on the dev. desk. is now not allowing me to sign in.
May 23 01:36:33 <set_> Yikes.
May 23 01:39:43 <set_> Otay.
May 23 01:40:03 <set_> Let me unplug and get this BBBGW plugged in on the other 'puter.
May 23 01:40:17 <GenTooMan> wasn't it on the network?
May 23 01:40:35 <set_> What, the BBGW?
May 23 01:41:02 <set_> Yea but I use the desktop for PuTTY on this rig.
May 23 01:48:04 <set_> bear w/ me here. I am having tech. diff. brb.
May 23 01:59:58 <set_> It is refusing my connection.
May 23 02:00:00 <set_> Off to read.
May 23 02:15:36 <set_> Okay.
May 23 02:15:56 <set_> I got the file b/c scp hates me and used FileZilla for now.
May 23 02:16:08 <set_> The file is transferred and ready to be played. Are you still around?
May 23 02:19:08 <GenTooMan> no
May 23 02:20:39 <set_> Dang it.
May 23 02:20:46 <set_> Come on, man. Please.
May 23 02:20:48 <set_> I need it.
May 23 02:20:50 <set_> Ha.
May 23 02:20:56 <GenTooMan> any what
May 23 02:21:18 <set_> Your knowledgeable shtick.
May 23 02:21:23 <GenTooMan> you have the mkvtoolnix suite installed
May 23 02:21:29 <set_> No.
May 23 02:21:36 <set_> I have debian w/out it.
May 23 02:21:59 <GenTooMan> Hmm That is a very handy tool.
May 23 02:21:59 <set_> Do I need that to play the recorded video for a mpeg4?
May 23 02:22:12 <set_> Okay. I will look it up and get it.
May 23 02:22:15 <GenTooMan> you have vlc or mpv installed?
May 23 02:22:23 <set_> No. It is a fresh install.
May 23 02:22:35 <set_> Debian Buster w/ 4.19.x.
May 23 02:22:58 <set_> On the dev. desktop.
May 23 02:23:12 <GenTooMan> you probably wan't mkvtoolnix (handy) also vlc and mpv
May 23 02:23:23 <set_> Okay. Let me go and check it out.
May 23 02:23:46 <GenTooMan> synaptic makes installation easy but it is also a pain to search for things
May 23 02:24:49 <set_> I will just use apt.
May 23 02:25:03 <set_> I already set up my sudoers file.
May 23 02:25:22 <GenTooMan> so doer huh
May 23 02:26:12 <set_> Yep. It took a while but that works just like the regular adduser, chmod, and other tools.
May 23 02:26:25 <KenUnix> HaHa SuDoHers
May 23 02:26:44 <set_> You sick $%^&. Stop it.
May 23 02:26:51 <set_> Sorry.
May 23 02:27:37 <set_> $%^& = Hots?
May 23 02:28:17 <set_> Okay.
May 23 02:28:20 <set_> Everything is installed.
May 23 02:28:28 <set_> it took like half a second.
May 23 02:28:57 <set_> Now what?
May 23 02:29:29 <set_> just vlc myfile.mp4?
May 23 02:29:37 <set_> I will try it.
May 23 02:29:42 <GenTooMan> you can try that..
May 23 02:30:21 <set_> it works.
May 23 02:30:24 <set_> Odd.
May 23 02:30:38 <set_> Windows said it was corrupt.
May 23 02:31:01 <set_> My file played fine. The fan 'she be spinnin' ma'.
May 23 02:31:05 <GenTooMan> windows? oh freak windows is MESSED up
May 23 02:31:28 <set_> I know. I am on windows to chat but my Debian dev. desktop works like a charm.
May 23 02:31:43 <set_> I forgot my username.
May 23 02:32:00 <set_> Then, I had to go behind the scenes and boot in safe boot mode.
May 23 02:32:12 <set_> Sign in w/ root was the only option.
May 23 02:32:34 <set_> I found my name in the /home dir. DUR!
May 23 02:33:19 <set_> That was my tech. diff. from earlier. I forgot how to sign in. Cough.
May 23 02:33:48 <GenTooMan> so the answer is the problem was windows
May 23 02:33:53 <set_> Yes.
May 23 02:33:54 <set_> Yes.
May 23 02:33:56 <set_> and yes.
May 23 02:34:27 <set_> Go, go-gadget, Debian Buster!
May 23 02:34:47 <set_> this mkvtoolnix stuff...
May 23 02:34:58 <set_> I looked up the file format it plays.
May 23 02:35:10 <set_> Matroska?
May 23 02:35:15 <set_> I read it over a bit.
May 23 02:37:27 <GenTooMan> it's a container format basically you can stuff a whole lot of things into an MKV file
May 23 02:37:57 <set_> I noticed it is similar but larger to a mp4 file.
May 23 02:38:05 <set_> Container!
May 23 02:40:03 <set_> I just the beginning of the Guide ideas. "Neighborhood party!"
May 23 02:40:23 <GenTooMan> right you should be able to use media info to get detailed info in the GUI
May 23 02:40:31 <set_> Oh. Okay.
May 23 02:40:34 <GenTooMan> also you can use it at the CLI (side note)
May 23 02:40:45 <set_> I was not able to run it from the command line just yet.
May 23 02:40:54 <set_> I need to learn more.
May 23 02:42:03 <set_> I saved 12 sec. of video and it took up a lot of MB in space. I need to be careful when dedicating video footage on the BBBGW to save space and not break-a the bbb.
May 23 02:43:10 <GenTooMan> does it have an SD card interface only?
May 23 02:45:00 <set_> Yea. My BBGW uses the SD Card b/c I want it to.
May 23 02:45:10 <set_> It has eMMC on it, though.
May 23 02:45:44 <set_> So, no. It has both SD and eMMC.
May 23 02:47:11 <KenUnix> You could put an emergency boot on the EmmC
May 23 02:47:54 <set_> I used mpv to watch the video.
May 23 02:48:02 <set_> THey be spinnin'.
May 23 02:48:08 <set_> KenUnix!
May 23 02:48:17 <set_> Sorry about earlier.
May 23 02:48:24 <KenUnix> Then pop the SD-Card boot off the EmmC then you can safely copy the SD-Card
May 23 02:48:39 <set_> Those ideas sound too complicated to me.
May 23 02:48:56 <set_> No offense.
May 23 02:49:33 <KenUnix> Remember zmatt wrote up a procedure for copyinh the SD-Card?
May 23 02:49:42 <set_> Nope. I missed that idea.
May 23 02:50:20 <set_> Too bad. Wait. Now, that you bring it up, I remember being left out of that chat.
May 23 02:50:26 <KenUnix> Well I can put it up on mt git site
May 23 02:50:35 <set_> I was not interested at the time.
May 23 02:50:50 <set_> KenUnix: Do you mess w/ video?
May 23 02:51:16 <KenUnix> No just the Playboy Pono
May 23 02:51:21 <set_> Dang it.
May 23 02:51:57 <KenUnix> You know Debbie does the entire state of Texas
May 23 02:52:08 <KenUnix> hahaha
May 23 02:52:25 <set_> Okay. Well, the BBGW plays video if you attach the correct webcam, have some source to save the file for playback, and you can plah it back on a dev. desktop.
May 23 02:52:49 <KenUnix> I'll put up that procedure later on my github site and let you know
May 23 02:53:01 <set_> or you can play it back on the BBGW but it is slower than a full-fledged desktop.
May 23 02:53:28 <KenUnix> Oh - How do you power a BBCW?
May 23 02:53:51 <set_> By 12v battery from a Cape and a powerbank.
May 23 02:54:09 <set_> The powerbank goes to the Micro USB.
May 23 02:54:38 <KenUnix> powerbank? So you can't use that to connect to the pc?
May 23 02:55:38 <set_> Yea. I can. I can connect to the pc.
May 23 02:55:49 <set_> I connected.
May 23 02:56:08 <KenUnix> I also heard by default the GPIO pin assignment are different then the BBB
May 23 02:56:39 <KenUnix> What do use a splitter?
May 23 02:56:58 <set_> Just wifi and the usb.
May 23 02:57:10 <KenUnix> Sorry GenTooMan .. Speaking over you
May 23 02:57:10 <set_> It is not so much different.
May 23 02:57:26 <set_> GenTooMan knows I am a sucker for chat. It is okay.
May 23 02:58:11 <KenUnix> Maybe I'll just wait for a case for the BBGG
May 23 02:59:24 <KenUnix> BBGG looks neat but there is no case yet
