Any recent version should work. Grab the latest from... http://www.xvidvideo.ru/ffdshow-tryouts-project-x86-x64/

if you take xbmc out of full screen into a window, do you see the ffdshow tray icons? you might need to unregister mpc vid codec.
also, maybe post a debug log and screen shot of the player stats (press O).
cheers

Here are screenshots of the version and the playback window. As you can see the built-in decoder.
And a screenshot Grafstudio.

hi everybody

does the audio analog output compares to dts-hd in dts-hd tracks?Is it bitstreaming?

thanks

Analogue audio I believe decodes within xbmc and sends as LPCM to the receiver. Bitstreaming is achieved using passthrough and HDMI.

At this stage neither xbmc natively, nor this branch is able to bitstream the HD Audio Codecs.

I understand that ... what i was trying to ask is if the audio quality is the same either way

thanks

Very much dependant on the indivdual - me I've never been able to distinguish a difference between DD, DTS, DTS-MA, True-HD - despite the differing bitrates and claims of the manufacturers. But not everyone subscribes to that, and bear in mind that I have 'cloth ears' Big Grin

Tiben - any progress on the audio playback issue liquidskin reported - playback of DTS Core track from DTS-MA?

Hey Xenotox,

Regarding analog, wasapi, and 5.1...

*For TrueHD decoded as LPCM, the audio quality will be identical as the source.
*For DTS-HD, no open source decoder exists, so you get the 1.5MB bitrate DTS 'core' decoded to LPCM, so it's identical to 1.5MB bitrate DTS.
*Good old AC3 and DTS outputed as LPCM will be identical to the source.

So basically you won't hear any difference compared to the source, with the exception being DTS-HD (as you'll be hearing the DTS 'core' decoded).

If you were bitstreaming (passthrough) the DTS-HD track, then you would being get the full chocolate biscuit, if you know what i mean! However as already mentioned, XBMC doesn't yet support bitstreaming of HD audio (although it's coming soon in the new xbmc audio engine, and in this project via ffdshow audio).

Cheers Wink

Regarding hearing a difference between TrueHD/DTS-HD and AC3/DTS...

*TrueHD/DTS-HD compared to DVD AC3/DTS, you'll hear a big difference.
*TrueHD/DTS-HD compared to BD AC3/DTS 'core', maybe you'll hear a difference!

The argument about TrueHD/DTS-HD v BD AC3/DTS 'core' will always rage on. You see, it's all to do with bitrates.

Cheers
