Let me understand this correctly:
The only way to copy all audio stream and the (valid) video streams would
be to use:
-map 0:a -map 0:v -vcodec copy -vcodec copy
If I use -map 0:a -vcodec copy -vcodec copy it doesn't copy the video
stream.
if I use
-map 0:a -map 0:v -vcodec copy -vcodec copy
It ends up copy the mpjpeg stream which breaks down streams programs since
the mjpeg is not a valid video stream but an ATTACHMENT which Media Center
adds for the thumbnail or something.
So what's the solution around this?
