Comment (by spookybathtub):

 The problem is that the source file has a valid audio track, and the
 output file does not.  ffprobe calls it "unknown" and Quicktime calls it
 "HDMV".

 I just noticed using ffmpeg -codecs that pcm_bluray is listed as a decoder
 only.  Does that mean we're incapable of passing it through using -acodec
 copy?  If that's the case, we should probably see an error message when
 trying.

 {{{
 $ ffmpeg -acodec pcm_bluray -i 00008.mov
 }}}
 I don't understand this command... it doesn't do anything.

 I could use -acodec pcm_s16be but that would be slower than a passthrough,
 and could theoretically degrade the sound a little bit.
