Hello,
problem with seeking occurs on specific files when calling
'''av_seek_frame'''(in_format_ctx, -1, 0, AVSEEK_FLAG_ANY),
where AVFormatContext *in_format_ctx.
Looks as it is regression, because mentioned call works with ffmpeg 0.5.2
( Originally committed as revision 23300 to
svn://svn.ffmpeg.org/ffmpeg/branches/0.5 ).
I reproduced it on test content from mplayerhq, file:
-
http://samples.mplayerhq.hu/archive/all/mpeg+mpeg2video+ac3++resolutionchange.mpg
Input #0, mpeg, from
'/home/krpa/ab/2011-06-09/mpeg+mpeg2video+ac3++resolutionchange.mpg':
Duration: 00:00:00.06, start: 0.184278, bitrate: 116480 kb/s
Stream #0.0[0x1e0]: Video: mpeg2video (Main), yuv420p, 1920x1080 [PAR
1:1 DAR 16:9], 38810 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
Stream #0.1[0x80]: Audio: ac3, 48000 Hz, 5.1, s16, 448 kb/s
also similar error encountered for first-3_MiB-panasonic-busker-video.mts,
and few other from my content, all of them were mpeg2video and ac3
encoded.
For example:

At least one output file must be specified
I'm using latest git revision with oldabi.
