[00:20] <teratorn> plm: ffmpeg -f lavfi -i testsrc=size=320x240 -t 10 test.mp4
[01:33] <TSM2> has anyone run benchmarks with the new ffmpeg with opencl?
[01:42] <buu> uh
[01:42] <buu> How do I pass codec options?
[01:42] <buu> -vbr on; ?
[05:02] <buu> Has anyone see an issue where encoding with -codec opus to a .ogg file ignores the specified -b:a setting?
[05:02] <buu> I specify -b:a 64k; and get 93k encodings
[06:48] <kriskropd> Can anyone offer a suggestion to work around an error like this? '[mpeg1video @ 0xae8660] MPEG1/2 does not support 10/1 fps' - I'm trying to convert .flv to .mpg
[06:54] <relaxed> kriskropd: it means you need to change the framerate
[06:54] <relaxed> try -r 25
[06:55] <relaxed> actually it says, Supported framerates: 24000/1001 24/1 25/1 30000/1001 30/1 50/1 60000/1001 60/1 15/1 5/1 10/1 12/1 15/1
[06:56] <kriskropd> relaxed: I expected I needed to rencode themt o something else at first :x - thanks, that worked
[14:48] <brontosaurusrex> converting I-frames only video to I-frames only output, is it possible to close encoding every N minutes, those generating multiple files, if yes, how?
[14:49] <brontosaurusrex> (The idea is to start editing the converted video while conversion is still in process)
[14:54] <brontosaurusrex> I'll be happy with "not possible" as well ...
[17:05] <MarcWeber> WHich is the best way to get commercial support on how to setup ffserver to distribute a mpegts stream?
[17:06] <MarcWeber> Everything is fine watching from vlc, but a dreambox 800 cannot view it whereas the original stream works fine. So I guess that I didn't setup ffserver properly yet.
[18:23] <izemize> hy
[18:24] <izemize> i use this command: /usr/bin/avconv -loglevel verbose -i "rtmp://127.0.0.1/deejay/2" -c:v libx264 -profile:v main -force_key_frames "expr:gte(t,n_forced*1)" -c:a libfaac -ac 2 -ar 44100 -f flv "rtmp://0.0.0.0:1935/mpd/2"
[18:24] <izemize> but no video output
[18:24] <izemize> anyone have good idea / solution?
[18:25] <sacarasc> #libav is the channel for avconv.
[18:25] <izemize> sorry
[18:29] <beastd> izemize: if you get and try with ffmpeg (if possible latest git master) you can of course come here for support
[20:10] <SirCmpwn> how do I control the number of cores ffmpeg can use?
[20:13] <buu> SirCmpwn: -threads ?
[20:14] <SirCmpwn> that's what I want
[20:14] <SirCmpwn> thanks
[23:35] <brontosaurusrex> converting I-frames only video to I-frames only output, is it possible to close encoding every N minutes, those generating multiple files, if yes, how?
