Logs show that ""invalid"" audio streams are skipped, although those are valid audio tracks. Below there are couple of logs with one and two audio tracks removed. It looks like ""invalid"" audio streams are (wrongly) detected to have 0 channels. I've uploaded one sample to http://rapidshare.com/files/283153720/audio.mpg.html and can provide more samples if needed. {{{ 2009-09-21 22:29:05.046 Input #0, mpegts, from '/tmp/test.mpg': 2009-09-21 22:29:05.046 Duration: N/A, bitrate: N/A 2009-09-21 22:29:05.046 Stream #0.0[0x201]: Video: mpeg2video, 90k tbn 2009-09-21 22:29:05.046 Stream #0.1[0x294]: Audio: mp3, 0 channels, s16 2009-09-21 22:29:05.046 Stream #0.2[0x295]: Audio: mp3, 0 channels, s16 2009-09-21 22:29:05.046 Stream #0.3[0x7eb]: Subtitle: dvbsub 2009-09-21 22:29:05.046 Stream #0.4[0x911]: Data: 0x0101 2009-09-21 22:29:05.046 Skipping invalid audio stream: 1 2009-09-21 22:29:05.046 Skipping invalid audio stream: 2 2009-09-21 22:29:05.046 Skipping unsupported codec 3 on stream 3 2009-09-21 22:29:05.046 Skipping unsupported codec 2 on stream 4 2009-09-21 22:29:05.060 720x576 P:1080000 13:48:36:009 #2 fl:2IT_0 pos: 376 2009-09-21 22:29:05.060 Found 1st valid video frame 2009-09-21 22:29:05.060 #0 PTS:16:45:14.891 Delta: 0.0ms queue: 1 2009-09-21 22:29:05.061 ptsIncrement: 3600 Frame #: 2 PTS-adjust: 16:45:14.711 2009-09-21 22:29:05.061 #0 fl:2BT_0 pos: 31772 ... }}} {{{ 2009-09-21 22:31:31.257 Input #0, mpegts, from '/tmp/audio.mpg': 2009-09-21 22:31:31.258 Duration: 00:00:22.45, start: 89483.030544, bitrate: 3563 kb/s 2009-09-21 22:31:31.258 Stream #0.0[0x204]: Video: mpeg2video, 90k tbn 2009-09-21 22:31:31.258 Stream #0.1[0x2b2]: Audio: mp3, 0 channels, s16 2009-09-21 22:31:31.258 Stream #0.2[0xfbb]: Subtitle: dvbsub 2009-09-21 22:31:31.258 Stream #0.3[0x911]: Data: 0x0101 2009-09-21 22:31:31.258 Skipping invalid audio stream: 1 2009-09-21 22:31:31.258 Skipping unsupported codec 3 on stream 2 2009-09-21 22:31:31.258 Skipping unsupported codec 2 on stream 3 2009-09-21 22:31:31.263 720x576 P:1080000 07:25:04:021 #2 fl:2IT_0 pos: 376 2009-09-21 22:31:31.263 Found 1st valid video frame 2009-09-21 22:31:31.263 #0 PTS:24:51:23.040 Delta: 0.0ms queue: 1 2009-09-21 22:31:31.263 ptsIncrement: 3600 Frame #: 2 PTS-adjust: 24:51:22.860 2009-09-21 22:31:31.263 #0 fl:2BT_0 pos: 59784 ... }}} " Bug Report - General closed minor 0.25 MythTV - Mythtranscode Master Head medium Fixed 1
