I have an mpeg file which plays without sound using the WDTV. I can
run it through ffmpeg and get a version which has audio; however, as I
have a number of these files, I’d rather not if I can avoid it. Based
on the mediainfo output, should it work?
ffmpeg line to “fix”:
time ffmpeg -i Prep_For_Sale.mpg -acodec mp2 -vcodec copy testoutput.mpg
