true hd and downmixed dd?

[raymondtrudeau]

hi is it possible using tsmuxer to select a true hd audio track and also have the same track downmixed to 5.1dd?thanks

Just demux and extract the ac3 core first, and add it to your mux.
Not too sure if it's needed though, isn't the core present for players that can't handle TrueHD? In others words, an incompatible player should automatically "downgrade"to the dd5.1 core right?

@Mirx not actually, player not able to play True-HD tracks does not recognize the audio track at all and sometime the track is skipped.

mplayer can handle true-hd ac

tsmuxer its ok for DTS-HD but still no for True-HD tracks!

is there a way to extract and use true-hd tracks?
thx :)
