[01:28] <v3nu5> hi im looking for a program to convert mp4 to avi for window 7 free thx for help
[01:30] <taqattack> click on file
[01:30] <taqattack> press F2
[01:30] <taqattack> change .mp4 to .avi
[01:31] <burek> hahaha
[01:31] <burek> :D
[01:31] <burek> nice one :D
[01:32] <burek> v3nu5, do you want to remux your media or reencode?
[01:32] <v3nu5> reencode, my old dvd player dont wanna read mp4
[01:32] <burek> mp4 is a container
[01:32] <burek> avi is too
[01:32] <burek> what is inside that container is what your player can't read
[01:33] <burek> and that thing inside is called stream (audio/video), which was encoded using a specific encoder
[01:33] <burek> try using ffmpeg just to remux the file with: ffmpeg -i input.mp4 -vcodec copy -acodec copy output.avi
[01:33] <burek> see if that works
[01:34] <v3nu5> ok thx
[01:45] <taqattack> burek: Do you have any idea why ffmpeg is eating up all this RAM? I've tried with both native rtmp and librtmp, and the issue still remains.
[01:45] <burek> taqattack, try asking in #ffmpeg-devel
[01:46] <burek> that's something that has to be analyzed more thoroughly
[01:49] <taqattack> Okay
[01:49] <taqattack> Thanks
[02:26] <zcat> Hi, midentify shows a bunch of codec info, but does ffmpeg have a way of also showing which profile an h264 vid was encoded with?
[02:27] <burek> afaik ffmpeg does show the profile
[02:29] <burek> for example here: http://stackoverflow.com/questions/10034059/ffprobe-shows-bitrate-of-0-0-or-n-a-for-h264-stream
[02:29] <burek> Stream #0.0: Video: h264 (High)
[02:32] <zcat> burek, yes, thanks, but 'high' covers a few categories. i'm just curious how many videos I have that are of profile >high at 4.1, since AMD's XvBA can't accelerate 'em
[02:32] <burek> 4.1 is a level
[02:33] <burek> and I'm not sure how to get that info from ffmpeg directly, maybe you can use ffprobe
[02:39] <zcat> burek, thanks. probably just easiest to sort by bitrate then.
[02:54] <silverrocker> what does idc stand for?
[02:55] <burek> i don't care?
[02:55] <silverrocker> no, in profile_idc and all these other things with idc behind it
[02:55] <burek> :)))))
[02:55] <burek> oh, ok :)
[03:20] <Zaita> What would cause url_fopen(&_formatContext->pb, _fileName.data(), URL_WRONLY); to return -2 (ENOENT) ? Does the file have to already exist empty?
[03:28] <Zaita> But only when I am trying to create .mp4 container, and it works fine with an .avi container
[03:29] <burek> Zaita, you might ask in #libav maybe or #ffmpeg-devel but be patient, because developers don't have much free time :)
[03:30] <Zaita> THanks

[04:07] <fling> which SDI devices can I capture?
[04:07] <fling> I need a list, please.
[04:07] <fling> Can't find it
[04:19] <Matt__> Hi, did anyone else run into a problem trying to install ffmpeg-php, error:  CODEC_TYPE_VIDEO undeclared
[04:33] <buhman> is it possible to multithread a h.264 encode job over multiple physical computers?
[04:34] <fling> buhman: http://omion.dyndns.org/x264farm/x264farm.html
[04:36] <buhman> hrm
[04:37] <buhman> can ffmpeg use an "x264farm" codec? :P
[04:40] <fling> can I capture from gstreamer? > http://schleef.org/2011/03/24/gstreamer-sdi-capture-plugins/
[04:40] <fling> can I oputput video to sdi card?
[06:24] <hellop> Is there anything I can do in ffmpeg to identify/resolve these errors?: concealing 3600 DC, 3600 AC, 3600 MV errors
[06:25] <hellop> full ffmpeg command and output here: http://pastebin.com/9G07ALVc
[06:28] <relaxed> hellop: Did you try without -re? why did you omit part of the output?
[06:32] <hellop> Hi, thanks. Yes I did try.  The only difference seems to be the bitrate goes up.  (that's the writing bitrate, right?)  Sorry, I omitted that part to save space.  Here is without -re:http://pastebin.com/Skk2Etca
[06:34] <hellop> It's a live stream, so I don't understand how the incoming bitrate would change.
[06:37] <relaxed> hellop: try dumping the stream with mplayer first, then encode with ffmpeg.
[06:38] <hellop> Can anyone point to a resource where I can figure out with these errors mean?  Since I can't see the source bitrate, I'm trying to figure out if it's, bandwidth, packet loss, or improperly encoded.
[06:39] <relaxed> mplayer -dumpstream -dumpfile OUTPUT $url
[06:39] <relaxed> it's having trouble decoding the video, "[h264 @ 0xa2f0c20] Missing reference picture" & "[h264 @ 0xa2f0c20] decode_slice_header error"
[06:40] <hellop> I only see the reference picture error when I start the stream, so I thought that might be because it's not starting on a keyframe.
[06:42] <taqattack> What causes "[dshow @ 0156f620] real-time buffer 232% full! frame dropped!"
[06:50] <hellop> relaxed, thanks for the suggestion.  This is the 4th tool that has problems with the stream.  mplayer err: rtsp_session: unsupported RTSP server. Server type is 'unknown'.  STREAM_LIVE555, Stream not seekable!
[06:51] <hellop> Do you think the problem is that the Camera has an incompatible encoding?  i.e. camera is just buggy
[07:11] <hellop> So, mplayer just exits.  Can anyone offer any insight as to what is wrong with the stream?  Like, defective camera, improperly implemented H264 encoding, network issues...  Need advice on how to troubleshoot/identify this.
[09:14] <cbreak-work> the newest ffmpeg can no longer open simple apple movie trailers
[09:21] <cbreak-work> nb_streams is 0
[09:44] <zap0> 'simple'
[09:58] <cbreak-work> well. It did manage to open them on n0.10.2
[09:58] <cbreak-work> doing a bisect at the moment
[09:59] <cbreak-work> but there are weird crashes, where long_name is a pointer with the value 0x1c00000000
[09:59] <cbreak-work> or other strange things
[09:59] <cbreak-work> like ffmpeg trying to mmap(size=157911088148480)
[10:00] <cbreak-work> maybe bisect jumped to some binary incompatible version
[10:36] <fling> relaxed: hey :p can you tell me about SDI capture + playback?
[10:51] <cbreak-work> it's also weird that sometimes ffmpeg builds ffprobe, sometimes it builds avprobe
[10:57] <cbreak-work> ah well, I guess newer versions are just broken.
[11:15] <cbreak-work> If anyone else wants to try it: http://trailers.apple.com/movies/disney/brave/brave-tlr3_h1080p.mov can not be read with libavformat/libavcodec fc882b
[11:17] <cbreak-work> f139838 can do it without problem
[11:18] <ubitux> cbreak-work: fc882b looks like an invalid hash; could you continue on the -devel channel?
[11:21] <cbreak-work> fc882b6e9c35fb22845c62cffa71f6eedb550db9 was just committed.
[11:22] <cbreak-work> but I bisected my way around a bit, and the problem was not created with that one, it's quite long standing I think. But the bisect didn't really work well so I don't think good conclusions can be taken
[11:23] <StaRetji> folks, would someone compile and create latest ffmpeg ipk for mipsel for me
[11:23] <StaRetji> I'm willing to pay to favor
[11:24] <StaRetji> I don't have space to compile myself and failed so far to do cross-compile
[11:24] <StaRetji> I need, ffmpeg, x264, aac and rtmp support :)
[13:18] <Radex> hi, after migration to 0.10 i'm getting warrning: "Incompatible sample format 's16' for codec 'aac', auto-selecting format 'flt'
[13:18] <Radex> it's passible to select flt using presets? i can't find it in doc
[13:30] <dhvu> At least some ASF files written by ffmpeg turn out to be incompatible with Helix and asfbin. Is anybody aware of this problem or anything related? Thanks!
[13:51] <rainmaker1> Hi, I have a stream that's already h264 but I would like to reduce bitrate. Is this possible using copy option for codec?
[13:58] <sacarasc> No.
[14:05] <hackeron> hey, question, I have an RTSP over http stream provided by a cheap Analog to IP Adapter on http://192.168.0.126/test.cmp -- FFMPEG can read it just fine. Is there anyway to use ffmpeg to turn that stream into an mjpeg stream (listening on a socket) instead of saving to a file?
[14:08] <llrcombs> hackeron: that sounds like more of a VLC-type thing than just ffmpeg
[14:08] <llrcombs> I could be wrong, but I don't think ffmpeg does that
[14:08] <hackeron> llrcombs: VLC can't play this stream :/
[14:09] <llrcombs> can you use a named pipe to receive the stream with ffmpeg, then broadcast it with vlc?
[14:10] <hackeron> hmm, maybe - I will try
[14:16] <StaRetji> hackeron: hm, let me think
[14:16] <StaRetji> if it can stream to rtmp server, it should stream for you too
[14:26] <hackeron> StaRetji: if what can stream to rtmp server?
[14:27] <hackeron> StaRetji: I'm doing ffmpeg -i http://192.168.0.126/test.cmp -o test.avi -- the test.cmp is identified as Stream #0:0: Video: mpeg4, yuv420p, 720x576 [SAR 1:1 DAR 5:4], 100 fps, 100 tbr, 100 tbn, 100 tbc
[14:29] <hackeron> StaRetji: but for some reason vlc won't play it, all I see is packetizer_mpegvideo debug: waiting for sequence start
[14:30] <StaRetji> ehm, you want to play it with vlc or you want to push it to a server
[14:30] <StaRetji> I thought you want to push it to server
[14:31] <hackeron> StaRetji: I want to turn the video into mjpeg and use ffsesrver or something so that another process can get the mjpeg -- for instance on localhost:4444
[14:31] <hackeron> StaRetji: so that I can do wget localhost:4444 and get the mjpeg
[14:33] <StaRetji> ffmpeg -i http://10.0.1.18:31344 -acodec libfaac -ar 22050 -vcodec libx264 -preset:v veryfast -maxrate 1792k -bufsize 5376k -filter:v yadif -f flv rtmp://10.0.1.2/live/livestream1
[14:33] <StaRetji> here is how I do it with rtmp
[14:33] <hackeron> StaRetji: I want the output to be mjpeg
[14:33] <StaRetji> I'm no expert but maybe play with value
[14:34] <StaRetji> here is -vcodec
[14:34] <StaRetji> libx264 does job for me, check what value is for mjpeg
[14:35] <StaRetji> for example, I guess you wont be needing -preset:v veryfast
[14:35] <hackeron> how do I get a list of values for vcodec?
[14:36] <hackeron> so presumably if I do ffmpeg -i http://admin:admin@192.168.0.126/test.cmp -vcodec libx264 localhost:4444 --- I should be able to open another terminal window and do wget localhost:4444 to get the x264?
[14:36] <hackeron> that just says: [NULL @ 0x7fb550852a00] Unable to find a suitable output format for 'localhost:4444'
[14:36] <StaRetji> -vcodec mjpeg
[14:36] <StaRetji> ?
[14:36] <hackeron> localhost:4444: Invalid argument
[14:37] <StaRetji> ehm, no, I didn't pasted code to literally use it
[14:37] <StaRetji> just to get idea
[14:38] <hackeron> StaRetji: My problem is the bit where I take the video out of ffmpeg and have it served from a socket
[14:39] <hackeron> StaRetji: this works: ffmpeg -i http://admin:admin@192.168.0.126/test.cmp -vcodec mjpeg output.mjpeg -- but how do I now instead of writing to file, serve the mjpeg from a socket?
[14:39] <hackeron> StaRetji: in your command you just specify a URL instead of a filename? -- but that doesn't seem to work
[14:40] <StaRetji> well, I have rtmp server and like this, I push to rtmp
[14:40] <StaRetji> have you checked docs?
[14:41] <hackeron> StaRetji: ah, so I'll need to write a server that will accept mjpeg and then accept client connections?
[14:41] <hackeron> StaRetji: can't find anything in the documentation about serving the video - there's ffserver it seems, just reading the documentation for that
[14:41] <StaRetji> yes
[14:41] <StaRetji> you check docs
[14:41] <hackeron> which ones? ffserver?
[14:42] <StaRetji> both??
[14:42] <StaRetji> lol
[14:42] <StaRetji> :)
[14:42] <StaRetji> btw, why it has to mjpeg?
[14:42] <StaRetji> has to be*
[14:42] <hackeron> StaRetji: I think I get it :) - so ffmpeg can output to a server but if I want to serve mjpeg I need to write my own server or possibly use ffserver :)
[14:43] <StaRetji> yes
[14:43] <StaRetji> I mean, I'm not aware that ffmpeg can server more than 1 client (push)
[14:43] <hackeron> StaRetji: I'm using motion detection software (http://www.lavrsen.dk/foswiki/bin/view/Motion/MotionGuide) that only works on mjpeg streams - so I need to convert this mpeg4 rtsp over http to mjpeg
[14:44] <StaRetji> oh, hm,
[14:44] <StaRetji>  that is bad luck
[14:44] <hackeron> heh, meh, should be doable :)
[14:45] <hackeron> will also look at gstreamer but last I tried it didn't like this stream either - seems ffmpeg is the only thing that will read it :/
[14:45] <StaRetji> ffmpeg_video_codec 	Values: mpeg1 (ffmpeg-0.4.8 only), mpeg4, msmpeg4, swf, flv, ffv1, mov Default: mpeg4
[14:45] <StaRetji> so, camera is giving what?
[14:46] <dhvu> Regarding my question regarding ASF compatibility, I'd like to test whether adding a silent audio track fixes my problem. In order to obtain this, how would I have to change the command line "ffmpeg -f vc1 -i raw_vc1 -vcodec copy test.asf" ?
[14:46] <StaRetji> I mean, link you gave do not mention mjpeg
[14:46] <hackeron> it's an Analog to IP adapter, it's giving: Input #0, nc, from 'http://admin:admin@192.168.0.126/test.cmp':
[14:46] <ubitux> ffmpeg 0.4.8, wait what?
[14:46] <ubitux> :D
[14:46] <hackeron>   Duration: N/A, bitrate: N/A
[14:46] <hackeron>     Stream #0:0: Video: mpeg4, yuv420p, 720x576 [SAR 1:1 DAR 5:4], 100 fps, 100 tbr, 100 tbn, 100 tbc
[14:47] <hackeron> it is activex only, I got the /test.cmp URL with wireshark, heh - it's very glitchy, if I enable audio ffmpeg no longer understands the stream
[14:49] <StaRetji> well, not sure if I follow, you have camera, then analog to ip adapter and streams in mjpeg?
[14:50] <hackeron> StaRetji: no, I have an analog camera, I connect it to analog to IP adapter and it outputs this weird mpeg4 over http on http://admin:admin@192.168.0.126/test.cmp -- but I need mjpeg, not mpeg4, so I'm looking for a way to turn the mpeg4 to mjpeg
[14:51] <StaRetji> got it, but software for motion detection, from link you gave here, do not mention mjpeg
[14:52] <StaRetji> it clearly says: ffmpeg_video_codec 	Values: mpeg1 (ffmpeg-0.4.8 only), mpeg4, msmpeg4, swf, flv, ffv1, mov Default: mpeg4
[14:52] <hackeron> StaRetji: this is output, not input
[14:52] <hackeron> StaRetji: input is only v4l and mjpeg
[14:53] <hackeron> StaRetji: "Motion can connect to a network camera through a normal TCP socket. All you need to give it is the URL. The URL given must return either one single jpeg picture or an mjpeg stream. For the time being Motion cannot connect to a video stream such a mpeg, mpeg4, divx. The URL must return one single jpeg image or an mjpeg stream! You can connect through a proxy server."
[14:53] <StaRetji> damn lol
[14:54] <hackeron> aha, heh - so I need to turn the mpeg4 to mjpeg somehow :)
[14:54] <StaRetji> so you have mpeg4 which you need to convert to mjpeg
[14:54] <hackeron> yep :P
[14:55] <StaRetji> ffmpeg -i video.mpg image%d.jpg
[14:56] <StaRetji> Turn a video to X images
[14:56] <hackeron> StaRetji: motion can only read from a TCP socket, not from files
[14:56] <StaRetji> yes, let's see
[14:56] <StaRetji> one by one
[14:56] <hackeron> heh, ok :)
[15:00] <hackeron> StaRetji: then what?
[15:00] <StaRetji> well, as I see, it seems that you have to make ffserver and then config file
[15:00] <StaRetji> something like http://ffmpeg-users.933282.n4.nabble.com/mjpeg-output-stream-issue-td3060653.html
[15:00] <StaRetji> this guys had troubles with it
[15:00] <StaRetji> but I think it is good way to start
[15:01] <StaRetji> ffmpeg -i  http://admin:admin@192.168.0.126/test.cmp http://ffserverip:8090/feed1.ffm
[15:01] <StaRetji> sonmethug like that
[15:01] <StaRetji> something*
[15:02] <StaRetji> feed1.ffm will hold conf for your output
[15:05] <StaRetji> burek / cevap / 10 upola s'lukom mate, are you here?
[15:05] <StaRetji> :)
[15:07] <StaRetji> burek: sorry mate, if you can ping me when you are available, I would like to ask you something, thx
[15:21] <hackeron> hmm, can someone explain the #Launch ffmpeg option in ffserver? - ffserver can launch the ffmpeg itself? - is there an example?
[15:23] <hackeron> does this look right? http://pastie.org/3810509
[15:24] <hackeron> it appears to be running but when I run curl http://127.0.0.1:8090/stream.mjpg -- all I get is --ffserver and nothing more :/
[15:24] <hackeron> I see one warning: Wed Apr 18 14:22:42 2012 Codec bitrates do not match for stream 0
[17:47] <ckb> I know this probably isn't a question for FFMPEG, but can someone explain to me how DRM works exactly?
[17:48] <ckb> DRM will not prevent a user from rtmpdumping my RTMP stream, right?
[17:49] <iive> drm is cryptographic scheme where the attacker is one of the recipients.
[17:49] <edgy> Hi, I want to ffmpeg -i file.rm file.mp3 but keep the original bitrate, how?
[17:49] <ckb> iive: explain?
[17:50] <iive> in crypto you usually have 2 people, who want to communicate, while there is 3'd one, attacker, who wants to intercept their communications, and even change it.
[17:50] <iive> with DRM you use crypto, to limit what the user can do with the content.
[17:51] <iive> however the user must be able to watch the content, that implies he must be able to decode it.
[17:51] <iive> so basically DRM is just an obfuscation scheme.
[17:52] <ckb> okay& so Flowplayer has a Secure DRM plugin, but requires authorization. Does this mean I must put the user's username/password in plaintext if I don't want to display a login box?
[17:53] <ckb> it just confuses me as to how DRM works. I feel like it's just like a penny.. a copper plating on top of zinc
[17:53] <ckb> or like a swarovski crystal
[17:58] <vertrex> hi
[17:59] <vertrex> Does we have to set manually the flags AVFMT_FLAG_CUSTOM_IO in the AVIOContext structure when settings a pb (IOContext)  for using custom IO
[18:00] <vertrex> it seem its done automatically by avformat_open_input but when calling av_close_input_file the buffer inside IOContext and IOContext them selves are never freed this causing a memory leak
[18:01] <edgy> vertrex: If I can't find someone to answer my basic question, I doubt that you find an answer to your this obscure question ;)
[18:02] <vertrex> hehe lol edgy, maybe I found some bug or doing somethings wrong but now it's ok for me it's fixed but could be useful for someone else
[18:02] <edgy> vertrex: then can you help me in my basic question
[18:02] <vertrex> what was your basic question ?
[18:02] <edgy> vertrex:  I want to ffmpeg -i file.rm file.mp3 but keep the original bitrate, how?
[18:03] <vertrex> haha lol I don't know just use the lib directly to create thumbnail of movie but didn't use the exe :)
[18:04] <elinenbe> Hi there, quick question.  Is there anyway to run an amovie filter on a live stream?  Eg, this works: "ffmpeg -y -f lavfi -i amovie="my_local_file.flv",silencedetect=n=-23dB:d=1 -f null - " but I can't do it on this eg: "ffmpeg -y -f lavfi -i amovie=http://www.example.com/web_file.flv,silencedetect=n=-23dB:d=1 -f null -"  I can't do it on a pipe or a streaming file... is there anyway around this?
[18:04] <ubitux> try escaping the : in the http://
[18:18] <elinenbe> ubitux: no workie!
[20:24] <taqattack> So is there a way to get constant framerate for output using libx264?
[20:35] <gustavo_cm> Hello guys. When I encode with libx264 I can set the quality of the encoding; can I do that with libvpx?
[20:35] <gustavo_cm> (I can do it with -vpre, for example. But I can't find any encoding profile/level/etc. for libvpx)
[20:36] <JEEB> I don't think vp8 has anything like profiles/levels
[20:36] <JEEB> and I don't think they have an alternative for the x264's crf setting IIRC
[20:37] <gustavo_cm> JEEB: thanks. But I don't know what's crf nor IIRC...
[20:37] <JEEB> If I Recall Correctly
[20:37] <JEEB> crf is the "constant quality" setting of x264's
[20:37] <JEEB> (constant rate factor)
[20:38] <JEEB> from x264's help "--crf <float>           Quality-based VBR (0-51) [23.0]" (the ffmpeg setting is -crf)
[20:41] <gustavo_cm> JEEB: hm, got it. Thanks. I don't use -crf, I use "-vpre max" to get the better quality in the minimum disk space.
[20:41] <JEEB> uuhhh
[20:41] <JEEB> that's not quality
[20:41] <JEEB> that's the compression/speed preset stuff
[20:41] <gustavo_cm> JEEB: best fidelity to original?
[20:41] <JEEB> also, you nowadays use -preset to set x264's internal presets
[20:42] <gustavo_cm> Hamm
[20:42] <Peace-> i have a problem with ffmpeg
[20:42] <JEEB> gustavo_cm, I have no idea what the preset file does, but as far as I am concerned the non-lossless x264 presets just set settings to match a certain speed/compression preset
[20:43] <Peace-> until test "true" = `qdbus  $mystufvariabletouseonmyscript wasCancelled` ; do echo ffmpeg  -i  ~/output.avi -y hello.mp4 ; done
[20:43] <gustavo_cm> JEEB: thanks for that. Is that better to use x264's presets instead of ffmpeg's? Why?
[20:43] <Peace-> if i set false it doesn't stop
[20:44] <Peace-> i have tried the same code with another software and it works
[20:44] <JEEB> gustavo_cm, the ffmpeg's presets used to exist just because first x264 didn't have such, and then later because no-one had implemented that part of the API in ffmpeg. Now it's there and there's no reason not to use it
[20:44] <JEEB> http://mewiki.project357.com/wiki/X264_Settings#preset
[20:47] <gustavo_cm> JEEB: thanks. Do you know what's "placebo"?
[20:47] <JEEB> it's exactly what it says on the tin. "All knobs to eleven"
[20:48] <JEEB> in other words, everything set to max -- with the expense of all speed
[20:48] <JEEB> also, of course this only governs the amount of time x264 will put into compression
[20:49] <gustavo_cm> JEEB: thanks! I'll try with -preset
[20:49] <gustavo_cm> JEEB: haha, I have no "preset" option, I'm using ffmpeg 0.6.2 in Trisquel
[20:49] <JEEB> lol
[20:49] <gustavo_cm> Which I should have updated already
[20:49] <JEEB> yeah, that's old
[20:50] <gustavo_cm> o/
[20:50] <JEEB> also, you will have to set a crf value or bitrate value depending on whether you just want quality X compressed as well as possible, or the best quality to a known set size you want to achieve
[20:52] <JEEB> (and for a set bitrate you most probably want to use two passes)
[20:53] <gustavo_cm> JEEB: got it, thanks.
[20:53] <gustavo_cm> JEEB: I'm encoding with "-threads 2" in a dual-core machine, it goes slower than with one thread only. Is that normal?
[20:54] <JEEB> with x264 the default should be "auto"
[20:54] <JEEB> which is 1.5x<core count>
[20:56] <gustavo_cm> JEEB: threads==1.5*cores, you mean?
[20:57] <JEEB> something like that, you can check the exact code in x264
[20:57] <gustavo_cm> thanks
[20:58] <iive> JEEB: isn't this sign that the OS scheduler is not working correctly?
[20:58] <iive> aka the need to have more threads than cores.
[20:59] <JEEB> dunno, it was tested at some point to be seen as a nice number. You probably would have to ask around #x264dev for more specific answers
[21:03] <JEEB> gustavo_cm, also if you are going to update your ffmpeg I recommend updating your libx264 as well :)
[21:07] <andrew__> Is there a way to use ffprobe to see the file format of a stream
[21:07] <andrew__> say something from m.youtube.com
[21:08] <andrew__> ?
[21:09] <gustavo_cm> JEEB: ok, thanks! I'm upgrading my system right now (new dist. release), will see it later.
[23:52] <hellop> I have used ffmpeg to create keyframe aligned files.  Is there a way to check the keyframe timestamps of files with ffmpeg or something else?
