New description:
After upgrading from 0.24 to 0.26 I have found that some recordings
repeatably crash mythcommflag when trying to do advert detection. It seems
to be correlated with recordings that come from the DVB cards, with the
following profile according to ffmpeg:
{{{
Input #0, mpegts, from '20992_20130227220000.mpg':
Duration: 01:04:58.89, start: 29964.196356, bitrate: 1876 kb/s
Program 1
Stream #0:0[0x1a21]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002),
yuv420p, 544x576 [SAR 32:17 DAR 16:9], 15000 kb/s, 25 fps, 25 tbr, 90k
tbn, 50 tbc
Stream #0:1[0x1a22](eng): Audio: mp2 ([4][0][0][0] / 0x0004), 48000
Hz, stereo, s16, 128 kb/s
Stream #0:2[0x1a23](eng): Audio: mp3 ([4][0][0][0] / 0x0004), 0
channels, s16 (visual impaired)
Stream #0:3[0x1a26](eng): Subtitle: dvb_subtitle ([6][0][0][0] /
0x0006)
Stream #0:4[0x1bb1]: Unknown: none ([11][0][0][0] / 0x000B)
}}}
Files recorded prior to the upgrade, with the same ffmpeg profile will
crash mythcommflag now, when they didn't under 0.24.
Please note the correlation between the "codec MP3 has 0 channels" and the
profile for the "visually impared" treack of "Audio: mp3 ([4][0][0][0] /
0x0004), 0 channels, s16 (visual impaired)"
I have attached a back trace from gdb and can forward a core file if
needed.
