[FFmpeg-user] No audio with
svoop at delirium.ch

I'm writing a little script which splits movies into 5min segments (because
my USB reading TV ridiculously features no rewind nor ff).
The following is executed with various ss-offsets, for example:
ffmpeg -i in.avi -acodec copy -vcodec copy -scodec copy -ss 0
-t 300 out1.avi
ffmpeg -i in.avi -acodec copy -vcodec copy -scodec copy -ss 300
-t 300 out2.avi
ffmpeg -i in.avi -acodec copy -vcodec copy -scodec copy -ss 600
-t 300 out3.avi
This works fine for the first segment with "-ss 0", but subsequent segments
like the above play no audio.
(If I try playback on VLC by the way, the audio is crippled on all 5min
Here's what "ffmpeg -i in.avi" shows:
Stream #0.0: Video: mpeg4 (Advanced Simple Profile), yuv420p, 624x352
[PAR 1:1 DAR 39:22], 23.98 tbr, 23.98 tbn, 23.98 tbc
Stream #0.1: Audio: mp3, 48000 Hz, stereo, s16, 127 kb/s
Any idea what's wrong here?
