 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:
