[00:09] <ShinyObjects> Hey everyone. I'm making an app that takes a raw h264 stream  and converts it to flv or f4v
[00:09] <ShinyObjects> What's a good starting  place in the ffmpeg library's documentation for me?
[00:09] <ShinyObjects> Oops, I was supposed to ask that in ffmpeg, I apologize
[01:25] <burek> is -dcodec missing from ffmpeg's documentation or is it deprecated?

[04:13] <CIA-63> ffmpeg: ffmpeg: add support for audio filters.
[04:13] <CIA-63> ffmpeg: Some of the FATE changes are due to off-by-one different rounding being used
[04:13] <CIA-63> ffmpeg: (lrintf vs av_rescale_q).
[04:13] <CIA-63> ffmpeg: Some fate changes are due to 1 audio frame less being encoded (the new variant seems
[04:13] <CIA-63> ffmpeg: matching what qatar does and according to ffprobe its closer to the requested duration)
[04:13] <CIA-63> ffmpeg: the mapchan feature sadly is lost in this commit because it depends on resampling

[12:59] <burek> is it possible to use -vpre with ffmpeg to store all the cmd line options in the file and just call ffmpeg with: ffmpeg -vpre bla
[13:12] <michaelni> burek, why not do ffmpeg `cat bla` ?
[13:13] <michaelni> i mean that would work with any command line tool
[13:13] <burek> is that possible?
[13:13] <burek> you mean like ffmpeg < bla
[13:13] <JEEB> ffmpeg bla would be taking bla into stdin
[13:13] <JEEB> *ffmpeg < bla
[13:14] <Tjoppen> burek: no, backticks paste into the command line
[13:14] <burek> oh I see
[13:14] <Tjoppen> $(cat foo) works too IIRC
[13:14] <burek> yes, I get it :) cool :)
[13:14] <Tjoppen> easier to nest than backticks. not that one needs more than one or two levels very often
[13:14] <burek> I was just thinking about creating some gymnastics with filters and to save them as some kind of file presets
[13:15] <burek> yes, and backticks are harder to spot, when pasted on forums and stuff
[13:15] <burek> thanks a lot :)
[13:16] <Tjoppen> the magic of bash

[19:19] <Compn> michaelni : what ever happened to playlist / joining multiple file support ?
[19:19] <Compn> is that code rotting somewhere ?
[19:22] <Compn> one of the last big features missing from ffmpeg.
[19:22] <Compn> mencoder has had it for years
[19:22] <michaelni> AFAIK it was far from finished when i last looked but thats long ago
[19:26] <Compn> oh maybe it was abandoned :\
[19:32] <Compn> oh ubitux is working on it
[19:32] <Compn> -amerge
[19:33] Action: Compn waits for vmerge
[19:33] <ubitux> i'm restoring -map_channel ATM
[19:33] <ubitux> and i'll look at -amerge again after that
[19:33] <ubitux> it should be fairly easy to merge it now that we have -af
[19:34] <Compn> good :)
[19:34] <Compn> except i dunno if thats what i want
[19:34] <Compn> i think i just want a way to cat 1.avi 2.avi > 3.avi 
[19:34] <Compn> amerge does something different
[19:36] <ubitux> yes that's something different :p
[19:36] <ubitux> -vmerge would be nice indeed ;)
[19:38] <ubitux> map_channel working again, hell yeah.
[20:07] <pasteeater> bcoudurier: do you still moderate the mailing-lists?
[20:55] <ubitux> anyone with a good/fun 5.1 aevalsrc expr? :)
[21:20] <ubitux> or at least a mono one that could be derivated in N variants :p
[21:26] <Compn> uhhhh
[21:26] <Compn> you mean a 5.1 sound test ?
[21:28] <ubitux> yeah
[21:28] <Compn> no clue :P
[21:29] <Compn> http://samples.mplayerhq.hu/multichannel/
[21:29] <Compn> theres one or two in there
[21:29] <Compn> but no idea 
[21:29] <Compn> if they are correct
[21:29] <Compn> whanot
[21:30] <ubitux> oh these are my testing samples
[21:30] <ubitux> but i was looking for generating fancy sounds with aevalsrc
[21:31] <Compn> oh
[21:31] Action: Compn is out of his element
[21:32] <pasteeater> Compn: want to babysit the mailing lists from 18-28 may?
[21:58] <Compn> pasteeater : i havent done it in a while ;)
[21:58] <Compn> but i will try, if someone reminds me
[21:58] <Compn> have you had to approve anything ? or just spams ?

[23:35] <pasteeater> and i dont add them to auto accept.
[23:36] <pasteeater> and most nabble users too
[23:40] <pasteeater> i usually just check the queue twice a day. some users will get impatient, subscribe, and resubmit so approving can result in dupes. you can tell when i feel extra lazy when i simply accept them instead of double-checking.
