Comment (by JohnGalt):
All codecs listed on that page are supported right now with m4v.
Dolby is in the process of getting TrueHD certified. DTS Master and DTS
are already certified as is clearly outlined when you click on the details
for each.
I think that there is HUGE value in FFMPEG supporting this given that
m4v/mp4 is the format that is supported by essentially all players/set-top
boxes. (mkv is not supported by Roku, ios or Windows 8 and is randomly
supported on android) Thus being able to write these tracks into the files
is required before anyone will enable bitstreaming these tracks out of the
files.
Given how many products use ffmpeg for encoding files, until you guys
support this, we won't get files that work, and thus we won't get players
that will stream the audio tracks out of the files properly.
Thus it's chicken or the egg, and you're the chicken that has to lay the
egg first.
Correct me if I'm wrong, but it should just be a matter of writting the
standard version of these tracks out to the file just like ac3 or aac is
written now. (i.e. a copy of the track should "just work")
