Title: Is anyone decoding Dolby TrueHD in MC15 using ffdshow
Post by: fitbrit on May 27, 2010, 11:33:23 am

To video users of MC15:

If you're decoding Dolby TrueHD, please list the filters you have working and whether you had to register them manually.

Do the new audio renderers in MC15 cause any problems outputting decoded LPCM via HDMI?

If you're bitstreaming TrueHD and/or DTS-HD MA, please say how as well.

Thanks for any insight. I'm currently using MPC-HC as an external app to play my mkv files because it works no matter what the audio video codecs of the file are. I'm hoping I can set up something similar using MC15 until I can get an audio bitstreaming video card.

Here you go.  I decode all my Audio then pass over HDMI as MPCM and a recent(ish) build of FFDSHOW is all you need for TureHD (note: still no direct show compatibile filters for the higher res DTS formats)

Thanks very much, jmone. I'm sorry it took me so long to respond. I really appreciate the time you took to reply. I'm still having sporadic success in MC15, but MPC-HC with the same filters and configuration works perfectly. I think it must be my choice of audio devices in MC15. I'll take another look. If you have any more time to help, I'd love to see a screenshot of your ffdshow "output" selections, and perhaps your MC15 Video options and choice of audio device/renderer.

Weird: I just switched to Haali splitter from Gabest's and it works now. On my HTPC it's the opposite - I need Gabest's splitter to get LPCM sent via HDMI. On my PC I'm decoding and sending via analog. Thanks for the help!

Here you are (from my desktop not my HTPC but I have no issues playing TrueHD at all!)

It seems that the decoding of 7.1 TrueHD is too much for my desktop CPU in some cases. It's time for some upgrades and a Ati bitstreaming card for the HTPC.

While I've an ATI HD5450 in the HTPC and it is capable of Bitstreaming, there is a strong argument to decode and send everthing as LPCM to the Receiver anyway (well if you like what reclock does!)
