No change my friend.

[albain]

Something's wrong i don't see the new fields that i added in the traces

[SamuriHL]

Not sure. I can try again once the movie's done. Assuming we don't lose power again.

EDIT: Just checked and it was definitely using the latest one you uploaded.

[albain]

Sorry again, I really need some cafeine : I posted the same build as before

Here is the right one

[SamuriHL]

Ok, will try again once my movie's done. Thanks!

[SamuriHL]

Yea, um, the receiver noticed but went to PCM mode and output no audio.

[albain]

If I have time I will make a tool to scan the media types accepted by the audio driver

[albain]

This time the log output is what I expected
but this still does not work.

What about AC3 and EAC3 ?

[SamuriHL]

AC3 pauses every frame so it's got this nice skipping thing going on but does bitstream, and as we determined earlier, EAC3 doesn't bitstream on my card with this driver.

[Andy o]

Can the MPC audio renderer be used for something other than bitstreaming, like WASAPI exclusive mode with decoded LPCM? Seems not to be connecting here with MPC-HC 1300.

Same as above when running DebugView and again silent when not running DebugView (though this time bitstream is not even detected).

Guys,
I got the green light from albain, so I commited my OSD modifications.

please let me know if there's any issue with the new patch, I won't rest until everything is in order. (sorry for resetting your OSD settings, it was unavoidable)

here is the patch that has been commited: (almost nothing has changed from beta 2)

Sure, I have the specs for that too. It is easier to implement than compressed stream. But after that TrueHD and EAC3 (and maybe DTS HD with a little luck) will work


@Tal
Thank you, I will make the needed adaptations of Media Control

[Andy o]

Thanks for the confirmation, I'll have to figure how to make MPC use the renderer. I've registered it, do I need to move the file to the system folder or something as well?

[SamuriHL]

No, you have to add it in the external filters and set it to prefer.

Great work Tal.

I did try that, but couldn't find it. I could find it on the output list though, but it doesn't connect just by selecting it there. I'll get it eventually.

[albain]

I have found a new bug : I am happy when I find a bug because this means that we can move forwad

It was not very clear but stream size must be referenced in bytes instead of bits for HD formats otherwise there is not enough room to write it. So it couldn't work at all

Here is the new link

It means that the format is refused by the mpc renderer and MPC reverts to directsound. If you get dbgview you will probably see this refusal.

The renderer is for now at development state : LPCM is not implemented, there are dropouts, and it is compiled in debug mode with many debug traces so it is slow and gives jitter.
Last thing but not the least, depending on the audio card/GPU and the driver, the official media types are refused by some and accepted by some others, so an additional layer will be added to try several types for each audio format.
For example :
if input format is TrueHD, try official MS true hd type, then try arcsoft one (for the xonar), and powerdvd one (for the auzentech)...
Maybe this can be avoided by passing LPCM type all the time and doing what we want whatever the format is.

[Skinleech]

Here is my log, using the latest beta & the rebuilt audio renderer from post #8744. The clip played in MPC, but I got no sound, my receiver showed multichannel.

I still get no audio pin in Graphstudio so can't try that way.

New log with Xonar driver version 1775, which also updated the slim firmware from 1.10HD to 1.11HD - no idea what's changed. Log looks the same though.
