I still don't think that DTS-HD, TrueHD and E-AC3 bitstreaming will ever work on anything other than ATI 5xxx and Xonar (and maybe next year's new NVidia generation), but I'll be happy enough if albain proves me wrong... |

Yup. No DD+ on that one. DD/DTS bitstreaming has been working for a while now (well, until the latest renderer change anyway). I'm hoping albain has some good ideas on how to fix the renderer so we can get bitstreaming working for HD codecs soon.

There was some confusion on that thread, on my part as well. Trailergod first said he could get DD+ (right now waiting for his reply) and then I asked him what card he was using, then Nimo made that post I linked above in reply, in which he didn't mean DD+, just DD.

Hi,
I am in a situation when the old renderer worked (with audio gaps/jitter) at least for AC3 and not the new one and I don't know why (luckily I have both sources): http://damienbt.free.fr/MpcAudioRend...old_working.ax Maybe you can try bitstream with the latest ffdshow I posted, otherwise you could try reclock too Thanks Last edited by albain; 14th November 2009 at 20:09. |

Yeah, this is something I can test....
Going back to the renderer that was in the beta 20 pack, I can get ac3 to bitstream with audio gaps and jitter, but only when DebugView is running. As before, this behavior is repeatable. Obviously, this is odd behavior. Maybe it's timing related? My experience with the WASAPI+exclusive implementations of J. River Media Center, Foobar and ReClock show that WASAPI+exclusive is very sensitive to buffer size. To the degree that a buffer that is 1 ms too large can break it in J. River's implementation. |

Why do i try non-working renderers again? |

Well because FFDShow is now fixed : TMT and ffdshow streams are identical. We just miss a working renderer.
But now I remember that the old renderer was not able to dynamically change of media type. James from Slysoft already gave me some tips. I also have a working sample app (but which does not use directshow) Also if someone has hints/sample code I take it Meanwhile I will go on trying different things until a clear sound comes out |

Hi thanks all for working so hard
it just strikes me though that should it be so tricky to get all of this working. What I mean is there not any specs available. Is this the reason why it is down to trial and error. Keep up the good work albain |

The fact that he got the bitstreaming support done is remarkable. It's just now how to pass through the bitstream to the receiver. For that you need a WASAPI audio renderer. That's easier said than done. He's working on it. Quite simply, what albain has accomplished so far is nothing short of amazing.
