this is a request for a new feature in ffmpeg. i searched the whole
documentation and came to the conclusion that this isn't currently
supported. if it already *is* supported, the documentation should be
extended to make this obvious.
the Sony PS3 isn't able to play VOB/MP4 files with DTS sound. however, if
the DTS soundtrack is "disguised" as PCM with a fake PCM 2.0 header, the
sounds is forwarded to the optical output, effectively enabling playback
of the DTS surround sound.
PS3MediaServer and MKV2VOB employ this hack to enable surround sound
playback on the PS3. i'd like to be able to achieve this with only ffmpeg
too, i.e. transcode a file to MP4, specify some command line flag to
enable this hack, and have it play with sound on the PS3.
some more information about the DTS/PCM2.0 header hack:
