Comment (by jonb):
Replying to [comment:17 cehoyos]:
> A h264 file (that is what your last line produces) cannot contain sound,
the format only contains raw H264 video.
okay, then I want to complain that FFmpeg continues regardless of
conflicting options.
-acodec copy tells FFmpeg I want it to copy the sound. That means I want
sound output. And if the output choice 00000.MTS.ss438.h264 indicates that
I dont want sound, then there is a conflict which means FFmpeg should not
continue. There is no reason to waste CPU cycles (and time) encoding
something which is useless.
