2160	ffmpeg produces mpeg files with audio not playable by some players	kadmandux		"Summary of the bug:

I'm joining (concat) some mpeg2 video files with ac3 audio (from my digital camera) without re-encoding. The resulting files have no sound if you play them with mplayer or HP Video (from HP Media Suite).

Mplayer says this:
''MPEG: No audio stream found -> no sound.''

How to reproduce:
{{{
ffmpeg -f concat -i list.txt -c:a copy -c:v copy video.mpg
}}}
Even more simple, without concat involved:
{{{
ffmpeg -i input.mpg -c:a copy -c:v copy video.mpg

I solved the problem with the workaround listed here:

http://www.das-werkstatt.com/forum/werkstatt/viewtopic.php?f=7&t=1834

The key is to ask for a target format:
{{{
ffmpeg -i input.mpg -target pal-dvd  -c:a copy -c:v copy video.mpg
}}}
The input files have contents like this:
{{{
Input #0, mpeg, from 'm2u00117.mpg':
  Duration: 00:01:26.36, start: 0.118222, bitrate: 7858 kb/s
