MediaPortal Audio renderer - better video playback quality (1 Viewer)

[tourettes]

I got exactly the same problems as Truri but without SAF installed.. i noticed it is only on HD stuff and only if the FPS does not match. For example my Laptop only can do 60Hz -> stutter. TV which change the refresh rate to 24p -> no stutter. Maybe Haali Splitter causes this problem but i dont know.

Isn't that a completely different issue? 60 Hz with 24 (23.976) fps material will always stutter since it wont fit into the bias max / min values (default 10% speed up or slow down).

Please post exact steps to reproduce the issue and evr, audio renderer and mediaportal logs for the case. Source fps and display device refresh rate capabilities included.

Truri's issue is random failure with refresh rate changer but from your' description it is a limit instead.

I tested your video renderer and get this results (screen below). I used v17 without the audio renderer connected yet. I registered the renderer once with an older version.. can i only replace this older renderer with the new one without register it again?

It is always safer to re-register the one that is wanted to be used:

1) to make sure wrong file is not loaded by directshow
2) to make sure no interface changes between different versions are causing crahes

Is it really possible to get 3 flat lines? =)

Those are alreafy flat enough to have stutter free playback. Onlt teh frame paint time varies a bit, but it seems to vary only few ms max so it will always be

Well, its not stutter.. there are major framedrops. Logs attached. First thought was that I.F.C. caused the drops. No mediaportal audio renderer connected. Instead Default DirectSound is used. Logs are captured while this Mediafile was playing:

The framedrops don't happen all time though.. if u start the PC -> start Mediaportal -> start the video (HD; it dont happen on one specific file only) -> no framedrops - stop the video -> start the video again -> framedrops CAN happen. It's more like random.. If there appear framedrops -> stop the video -> start it again -> framedrops CAN be gone.. sometimes u have to start - stop - restart the video more than one time till you have no framedrops. So this is really strange behaviour..

First when troubleshooting stuttering, disable every single 3rd party plugin (there are lot of cases where the 3rd party plugins are affecting the playback quality). Even revert to B3W default skin since many skins have their own plugins that can reduce the playback quality.

2010-10-21 20:21:19.312323 [Debug][MPMain(1)]: DirectShowUtils: added filterefault DirectSound Device to graph

MP audio renderer is not even tried to add the graph. Are you sure it is configured to be used? First you need to find the reason why it is not added to the graph, then we should check how the playback is working at that point.

The framedrops don't happen all time though.. if u start the PC -> start Mediaportal -> start the video (HD; it dont happen on one specific file only) -> no framedrops - stop the video -> start the video again -> framedrops CAN happen. It's more like random.. If there appear framedrops -> stop the video -> start it again -> framedrops CAN be gone.. sometimes u have to start - stop - restart the video more than one time till you have no framedrops. So this is really strange behaviour..

One reason for such random behavior is that the MP audio renderer is not used. EVR mixer "picks up" a random v-sync position (or actually it wont pick, it just takes some ramdom point of time as the frame target...).

Other one could be that the refresh rate changer fails to correctly change the refresh rate.

Silent stream / corrupted audio with NVidia HDMI audio drivers - AVS Forum That would require some testing...

I found wat was wrong with the missing voices. The middle speaker didn't work at all.
I disabled it in the settings and now all is well!

WOW! Happy.

Thanks for your time and developing this great audio renderer.

AW: Re: AW: MediaPortal Audio renderer - better video playback quality

Does the issue happen without the audio delay set? What is heavy drifting? Please be a bit more descriptive - like 1 second in 15 minutes or 50 ms in 2 hours. That kind of information would be helping. Just telling that A/V sync drifts wont help that much (after all here it works again with ver 17 + AC3 encoding, no drifting is happening during 2 hour movie).

Ver 17 + audio delay + AC3 encoding enabled -> drifting.

Actually it doesn't even work with the non-AC3 encoding case Could you test if putting 10 (as decimal) in audio delay creates correct 100 ms delay?

m_pClock->SetAudioDelay(m_Settings.m_lAudioDelay * 100000); // setting in registry is in ms

should be:

m_pClock->SetAudioDelay(m_Settings.m_lAudioDelay * 10000); // setting in registry is in ms

works now fine with v18 - thanks!

Sometimes the bug(s) aren't in the free software after all

not shure whether this is related to MP Audio Rendere - but could you perhaps have a look at this? (https://forum.team-mediaportal.com/...s-endless-loop-after-switching-channel-89028/) the rerendering is rerequested due to an audio change and running in a loop.

Nothing points into the audio renderer direction in the logs (in general the audio renderer is a dummy part when it comes to graph building - it doesn't initiate any rebuild etc.).

Since you can reproduce the issue please try without the MP audio renderer - that is the easiest and lest effort requiring way (I cannot access multiseat configuration as a test environment).

In any case the specific issue should be handled in the already existing thread - unless it is MP audio renderer that triggers it.

AW: MediaPortal Audio renderer - better video playback quality

thanks tourettes - switched away from rtsp now everything working fine.

Today i had a problem with the mpaudiorenderer getting buffer underruns on one channel. All other channels were working fine and also the picture is still running fine. Any idea?
