I convert HD satellite streams using
cat *.TS4 | ffmpeg -i - -c copy in.avi
ffmpeg -i in.avi -c copy out.avi
in.avi works perfect, plays in VLC, can be converted to any other format.
out.avi works the same if AC3 sound is auto-selected in line 1
with MP2 sound auto-selected VLC plays no audio, other players on
different platforms have mixed results:
no playback at all, no video, no audio, delayed audio, symptoms mixed in
one file
Filesize is reduced after line 2 by 160 bytes.
diagnostic output from line 2:
