[01:48] <ramiro> michaelni: the thing is that the granularity is huge. it's 1s. it can be made smaller, but then the table grows proportionally. the index table doesn't allow setting the real timestamp inside that 1s.
[01:48] <ramiro> for example in the regression tests the real timestamp is 960, but it gets indexed as 1900
[01:49] <ramiro> and the table is designed to work with backward seeks. so forward seeks shouldn't use it.
[01:50] <ramiro> imo the index table should be used as an initial estimate. find the packet from the table, then look for the next and the previous keyframe and determine their real pts. from that, look further if necessary or just return the frame if it's found
[01:52] <ramiro> or just drop the table altogether in asfdec and use normal binary search
[02:16] <burek> is there a way to select certain/specific alsa audio output device with ffplay
[03:57] <burek> is it too hard to make a feature, just like in vlc, that will allow ffmpeg to retrieve youtube videos directly?
[04:10] <Compn> burek : no, either using a wrapper to youtube-dl.py or just copying what vlc does
[04:10] <Compn> should only take probably 20 mins or less by any smart devel

[04:11] <burek> :)
[04:13] <burek> yes, I noticed that a lot of people have this solved
[04:13] <burek> like JW Player (web video flash player)
[04:15] <burek> I see that youtube-dl has got support not only for yt but for a lot of content delivery websites too
[04:15] <burek> cool thing :)

[09:50] <ubitux> we don't have a placeholder for "ffmpeg regressions", right?
[09:56] <michaelni> placeholder ?
[09:56] <ubitux> i mean just like lavfi-regressions.sh
[09:57] <ubitux> we don't have a "ffmpeg-regressions.sh"
[09:57] <ubitux> (for cmd line parsing or generic options etc)
[09:57] <michaelni> no, we dont have such a thing yet
[09:57] <ubitux> ok
[10:26] <spaam> ubitux: cant you use fate for it ? 
[10:28] <ubitux> you mean the fate/*.mak?
[10:28] <ubitux> *-regression.sh scripts are part of fate

[12:38] <CIA-17> ffmpeg: lavf: Fix the last PTS to be generated using -fflags +genpts
[12:38] <CIA-17> ffmpeg: To reproduce the problem, using ffprobe:
[12:38] <CIA-17> ffmpeg: ./ffprobe -show_packets -print_format compact -fflags +genpts -i
[12:38] <CIA-17> ffmpeg: fate_samples/mxf/C0023S01.mxf
[12:38] <CIA-17> ffmpeg: You will notice that the last video frame does not have it's PTS being
[12:38] <CIA-17> ffmpeg: set, even with using genpts.
[15:56] <burek> is it possible to have ffprobe -show_streams with ffmpeg?
[15:57] <Compn> its the same commands basically
[15:57] <Compn> so should be
[15:57] <Compn> ffmpeg -i file
[15:58] <burek> i tried ffmpeg -show_streams but no
[15:58] <burek> so I thought maybe it's ffprobe only
[17:03] <burek> hm, im puzzled with this paste: http://pastebin.com/WJ7qaxA2
[17:03] <burek> is it possible that format and all the streams can contain metadatas each
[17:04] <burek> metadata for format + meta for stream #0, meta for stream #1, etc.. ?
[17:05] <nevcairiel> yes, there is stream based metadata
[17:09] <burek> thanks :)
[17:24] <spaam> ubitux: yes. if the output differ then something is wrong..
[17:25] <ubitux> heh?
[17:33] <spaam> ubitux: yes. its like that 
[17:33] <CIA-17> ffmpeg: 03Clément BSsch 07master * r614716f583 10ffmpeg/libavformat/mov.c: (log message trimmed)
[17:33] <CIA-17> ffmpeg: mov: do not print string len in handler_name.
[17:33] <CIA-17> ffmpeg: The handler name is stored as a pascal string in the QT specs (first
[17:33] <CIA-17> ffmpeg: byte is the length of the string), thus leading to an invalid metadata
[17:33] <CIA-17> ffmpeg: string export.
[17:33] <CIA-17> ffmpeg: Also add a second length check based on the first character to avoid
[17:33] <CIA-17> ffmpeg: overwriting an already specified handler_name (it happens with Youtube
[17:33] <ubitux> spaam: i don't understand what you are talking about :p
[17:34] <spaam> ubitux: neither do i
[17:35] <ubitux> :)
[20:51] <bcoudu> how do we debug format timestamps in the latest version ?
[20:52] <bcoudu> -fdebug ts doesn't work anymore
[21:42] <michaelni> bcoudurier, -fdebug ts seems to need -v 99 
[22:02] <bcoudurier> right

[23:38] <ubitux> bcoudurier: the -amerge code won't require much change when we will need to move to a better solution; it's likely we will just have to change the "amovie=foo.avi:si=3" into something like "[0:3]" as source (see -filter_complex patch proposition by Anton)
[23:40] <ubitux> and anyway, the "hack" is pretty isolated
[23:40] <ubitux> the visibility of the feature will also be restricted (i removed the changelog entry, and added a warn in the doc)
[23:43] <ubitux> are you proposing yourself to help with the lavfi auto reconfiguration, or audio stretching?
[23:54] <beastd> "-filter_complex" sounds pretty bad from a naming perspective. didn't read the proposal though.
[23:56] <ubitux> it's still a RFC
[23:56] <ubitux> from what i can tell :)
