7.1 Channel Audio Bitstream Passthrough Support?
Posted: Mon Mar 17, 2014 3:51 pm
Sorry if this is covered already. I did try searching first.
Is the "Encoded audio passthrough for AC-3 and DTS" option supposed to support DTS-MA 7.1 and/or Dolby TrueHD 7.1? I've tried with just that option alone checked as well as that option along with LPCM checked and I can only get 5.1 channels. (The LPCM was just a hopeful last ditch effort. It's my understanding that transcoding to LPCM, at least for DTS-MA, would require some kind of proprietary decoder licensed by DTS or something.)
Here is the media info for the audio track of the file I'm streaming. My renderer is a Slim PS3 that I've verified set up correctly to play DTS-MA 7.1 with Blurays. I use it along with an Onkyo AVR. The AVR is very precise in reporting what type of input it is receiving.
Only 1 audio stream:
And attached is my debug.log from when I tried playing the file above transcoding with FFmpeg and then MEncoder.
Result of FFmpeg: PS3 reported 5.1 Dolby Digital in the OSD. Yep, only 5.1 and Dolby Digital instead of DTS (!?!?!). AVR reported 5.1 PCM.
Result of MEncoder: PS3 reported 2 channel LPCM in the OSD. AVR reported 5.1 DTS (meaning DTS Core).
Thanks in advance for any interest in this.
