[fixed] Video and sound syncronisation (1 Viewer)

[1stdead]

Hi morpheus_xx,

Didn't have time to ask, but are you coming with a new build then as this one still didn't fix it?

Hi morpheus_xx,

Didn't have time to ask, but are you coming with a new build then as this one still didn't fix it?

The next comming build have a big change in the code. We made some experiment sunday evening, and without going in the detail, frames are now passed in another way (textures instead of stetch+rect IIRC what Morpheus said but I must admit it means nothing to me )

On my side, it massively reduced the amount of stuttering, but I still have sometime some bad frames on my MKV test file, or rarely a black one presented.

For HDTV, it seems now very good, but I have to disable any hardware acceleration in LAV to have a good result.

Also, it seems these changes have broke the PIP feature, so their's still work to do.

I think Morpheus will put online a new build ASAP for you to help us to close this issue once for all! Maybe we will work on it again for some days before, I can't say... But we (mostly Morpheus) are working hard on it! I've been myself testing the last changes the all evening...

Thanks to all for your help and support, you will be kept informed.

Cheers.

Smeulf.

Also, it seems these changes have broke the PIP feature, so their's still work to do.

The builds which are presented here are builds with unclean code, just to test how video problems like the frame flashing problem can be solved. They only try to fix the playback problems and could break other functions. But that is no problem because the only reason of those builds is to track down the playback problems.
When we have found the problem, we'll repair the original MP2 code, which can always be downloaded from github.
So all those builds presented in this thread or in the context of bug finding are explicitly declared "unstable".

new build added above: https://forum.team-mediaportal.com/811847-post71.html
also see notes...

please provide feedback how the playback looks now. better test without stats enabled, the impression is more important then the renderstats....

Indeed it it unstable and for this particular issue only, and my point was not to report a new bug, but just to point out that the new way was not working with PIP at the moment. I just very hope it's not incompatible... It was writted most as a side note

Will now check last build...

Cheers.

EVRCustomPresenter using Texture mode: 0 : Small shuttering here as well in all three renders. Almost watchable now like mode 1. There isn't much difference between the modes.


EVRCustomPresenter using Texture mode: 1: Flickers very little, but still noticable in all three render modes. Screen flashes black for like 1ms. It actually begins to be watchable.



---------------------------------------------------------------------------------------------------------------------------------------------------------------

There definite a difference between my laptop and htpc. Htpc is allmost watchable while laptop is still flickering very badly.

Tried Ffdshow DVAX and shutting was still large in all test cases

 

[Smeulf]

Please, can you also try with subtitles disables ? Here it seems it makes the video perfect without subs...

 

[1stdead]

Hi Smeulf,
I don't think i have subtitles enabled at all

 

[Smeulf]

Oh tks 1stdead.

So here I have :

UseTextureCallback = False => not good at all

UseTextureCallback = True => Good for my mkv test file as soon as I remove the subtitles. If subs are enabled, it stutters when the sub appears it seems, but not always.

For an another file (HDTV), I have some stutters from time to time. No matter the screen refresh rate or the rendering mode.

[Edit] Oh btw, A/V sync is now very ok!! [/Edit]

Quick rectification : my MKV still stutter, but very few. But you're on the right way Morpheus.
