[02:59] <kode54> cute: "libav (the real active upstream)"
[04:02] <ari-_-e> I'm just curious what the relationship is betweem ffmpeg and libav at this point
[04:06] <newl> incentuous
[04:06] <newl> or cannabalistic
[04:06] <newl> or apathetic?
[04:06] <ari-_-e> incentuous?
[04:07] <ari-_-e> incestuous?
[04:18] <ari-_-e> I'd be interested in more detail if anyone feels like providing it
[04:18] <ari-_-e> it looks like they're pulling from each other at least to some degree
[04:21] <newl> dt
[05:50] <Orbixx> Audio is out of sync with video after converting.
[06:25] <smokeyrat> Is "bps"/bits per second the same "thing" as Hz", as in, they can be directly translated to each other?
[06:37] <brocatz> hi, can someone help me with direct show?
[06:37] <brocatz> am trying to capture from a web cam and my audio is out of sync
[07:06] <brocatz> the camera encodes to h264 onboard
[07:06] <brocatz> but i'm not sure how to tell it to do that
[09:19] <truexfan81> can anyone tell me how often a new version of ffmpeg gets pushed to git-hub?
[10:18] <raptor67782> how to retrive this stream : ffmpeg  -i   "http://direct.francetv.fr/regions/evt/medit-nice-direct.wsx?MSWMExt=.asf"    stream.wmv
[15:05] <burek> \o/
[15:14] <raptor67682> burzum: no tv really? - so you could also try this script: http://pastebin.ca/2171050   it has also us webcams, ... but it tooks me a lot of time to figure out how to make it works. I couldnt find a manual
[22:22] <mikatalk> Hello there!
[22:23] <mikatalk> I m having ffmpeg compile video from a named pipe stream of ARGB raw image data and it works fine. When i try doing that for the audio as well I get stuck.
[22:23] <mikatalk> Is there a way to have two named pipes as inputs or should i first render the video, then add the sound in a second pass?
[22:24] <mikatalk> your opionion on this would be much appreciatted
[22:30] <cbreak> mikatalk: I don't see why it should not work
[22:31] <cbreak> as long as both pipes are continuously filled
[22:33] <mikatalk> but so when i use named pip i use -i -
[22:33] <mikatalk> but if there is a second one what should i use to make sure it get the right pipe?
[22:38] <cbreak> that's not a named pipe
[22:39] <cbreak> that's standard input
[22:39] <cbreak> a named pipe would be mkfifo namedpipename
[22:39] <cbreak> ffmpeg -i namedpipename
[22:39] <cbreak> otherprocess --writeto namedpipename
[22:45] <mikatalk> this is my command
[22:46] <mikatalk> " framesToPipeServer.rb | cat namedPipe | ffmpeg -y -f rawvideo -pix_fmt argb -vcodec rawvideo -s 320x180 -i - -r 24 -qscale 1 video.mpg"
[22:46] <mikatalk> it works perfectly
[22:47] <cbreak> no named pipe.
[22:47] <mikatalk> now i have another server file that streams the audio in a fifo
[22:47] <cbreak> you use -i -
[22:47] <mikatalk> really? i m not an expert but i used mkfifo to create namedPipe
[22:47] <cbreak> if you want to use a named pipe, use -i namedpipe
[22:47] <mikatalk> i see, let me try that
[22:48] <cbreak> no need for cat or that rb thing in that line either
[22:48] <cbreak> start the process that writes to the named pipe after ffmpeg
[22:48] <cbreak> in a different command line
[22:48] <mikatalk> you re right it works as well
[22:49] <mikatalk> let me try to add the sound pipe
[23:06] <mikatalk> weird...
[23:06] <mikatalk> ffmpeg -y -f rawvideo -pix_fmt argb -vcodec rawvideo -s 320x190 -i ./namedPipe -r 24 -qscale 1 video-no-sound.mpg
[23:06] <mikatalk> this above works
[23:07] <mikatalk> if i add -i ./audioPipe -acodec copy it won t work :(
[23:07] <mikatalk> ffmpeg -y -f rawvideo -pix_fmt argb -vcodec rawvideo -s 320x190 -i ./namedPipe -r 24 -qscale 1 -i ./audioPipe -acodec copy /Users/mika/Documents/tmp/renders/video.mpg
[23:10] <relaxed> mikatalk: frame rate and qscale go after the audio input.
[23:11] <mikatalk> oh ok i will try now
[23:11] <mikatalk> thx
[23:11] <relaxed> (or, frame rate goes before the video input)
[23:16] <mikatalk> it doesn t seem to matter
[23:16] <mikatalk> since i can render video fine
[23:16] <mikatalk> it breaks when i add the audio input
[23:16] <relaxed> pastebin
[23:17] <mikatalk> my command lines?
[23:17] <relaxed> command and all output
[23:17] <mikatalk> ok
[23:25] <mikatalk> http://pastebin.com/A1n9A0Zf
[23:25] <mikatalk> where both server pipe video to 'namedPipe' and audio to 'audioPipe'
[23:26] <mikatalk> basically i had ity working fine with the video server and a static mp3 file
[23:26] <mikatalk> but when using a server for the audio t breaks
[23:27] <cbreak> cat /dev/null sounds stupid
[23:30] <mikatalk> i know sorry i switch to ./audioServer.rb > /dev/null
[23:32] <mikatalk> don t even need the > dev/null since the server does it already, but i was trying to show what the server was doing
