MediaPortal Audio renderer - better video playback quality (2 Viewers)

[Lotsofjazz]

I am sure it must be something simple, but I cant figure it out,

Posting log would be the 1st step.

Logs added.

Graphstuio doesnt show any graph, so I am not sure if mpaudoprenderer is runing properly

for system, see te link at the left.

Thanks in advance!

ForceDirectSound: 1

Directsound shouldn't be used (I think it might even need to be dropped since it is not up to date and there is no resources for supporting it - it is maily useful for XP since it wont have WASAPI).

To get graph from Graphstudio you need to register (regsvr32 proppage.dll under admin right)
Copy the file in folder of your choice and register it

Lotsofjazz: look at the ffdshow audioconfig i guess the mixer is active and downmixing. I bet you didn't read my posts

Thanks for the dll, it works now!

Immediately checked the graph of course and noticed that mpaudiorenderer is loaded, but not connected to anything, in stead the movie audio is connected with ffdshow audio decoder and then the Default Audio renderer.

So, what to do next?

@lotsofjazz: look at the ffdshow audioconfig i guess the mixer is active and downmixing. I bet you didn't read my posts

No, I did, mixer is off.

ForceDirectSound: 1

Changed to disabled, but no change of course because the MPaudiorenderer is not used at all(see above).

Shall I try to use wasapiexclusive? I figured from the first post that because I am running W7 it was better to disable wasapiexclusive, right? (what does wasapi mean anyways, I have no clue what it is or what it does)

Anyways, many thanks for the help so far, it is much appreciated.

Enable the exclusive WASAPI. It allows audio renderer to control the audio format - without it the selection you have made in OS / audio config will be the only format that can be used (usually 2 channel and some specific sampling rate).

And if it still fails then please provide again the audio renderer log (others aren't needed).



WASAPI == The Windows Audio Session API

 

[Lotsofjazz]

I have enabled WASAPI exclusive and tried briefly but no change...but now I am away from my HTPC, I will try again tonight after a reboot, if still not good I will post log again.

Thanks,

Ok, found it myself..

in ffdshow Audio Decoder settings, Output> Connect to: Any Filter ( was DirectSound)

It works now guys.. and the difference is realy noticeable! smoother video.. great!

 

[wouter1971]

Yeah it's realy nice smooth video....now let us pray that tourettes will update mpaudiorenderer to support LAVF codecs.

I have checked with Graphedit and shift-1, while playing a X264 1080P movie with standard DTS Audio.

The Audio is re-encoded to nice AC3 5.1, but a littlebit of the detail and depth is lost, compared to the original and decoded by the Marantz DTS decoder (I can check playing directly in TotalMediaPlayer 5) but it is more then adequate.

With shift-1 I can confirm Video is speeded up a tiny bit, from 23.something FPS to 25 FPS, the green line is still a bit wobbely (time required to render each frame), but the red line is allmost straight!, Before using mpaudioerenderer with this movie the red line show a spike down, allmost every second.

Graphedit shows Mediaportal Audio renderer is now used to render the audio.

Maybe I can improve the audio quality a bit by increasing the sample depth to 24 bits, will tweak a bit more tonight.

I have one movie with 1500 bps DTS that now acts as a slide show, and no sound.. It is a m2ts file, reamed to mkv so it could be splitted by LAV Splitter, but now I have installed Haali again, I guess this is a splitter issue, and has nothing to do with ffdshow or mpaudiorenderer.. changing the extension back to m2ts did not help. Will teak on this movie tonight as well.

QUESTION:

Is it possible to use AC3 passthrough with TV Only? because with TV there is no need for re-encoding, because it is delivered by my cable company in 720P50 or 1080i50 anyways and matches my TV refreshrate perectly. It works, but sounds seems a bit unstable now with TV, like the sound cannot find a center position or something, voices in a talk program move around the center and are not as focussed as it was before.

Thanks!
