3D MVC MKV Freeze and center audio is lost

KrissKross · March 2, 2017 at 11:27 AM

Hello everybody

I upgraded mi Raspberry Pi3 from 7.95.3 via .tar file in the update folder. Update worked fine but I still have the same issue since upgrading from 7.0.3.:

With 3D MVC MKV Files (Remuxed by Makemkv and original Streams) the picture freezes when I forward the movie by chapter or forwarding by steps.
I also have lost center audio during playback with passthrough from the original audio Stream (DTS-HD). When the audio Stream ist decoded to PCM the audio works fine. All other movies work fine, also when I have a ripped 3D MKV (SBS o. TAB). I tried all different kind of settings, but didn't solve the problem.

Does anybody have the same problem or do I have problem with the settings?

Thanks

Hello

Did some research and did the following:

- Fresh reinstall of Libreelec 8.0.0. Didn't solve the problem!
- Did some twinkeling with the advancedsetting.xml file in the userdata folder. The playback got more stable and kodi didn't crash anymore. Put in the following:

The problem still occurs though. During playback of 3D MVC MKV files (ex. San Andreas) when I jump to the next chapter the screen freezes. If I go a step forward the movie starts playing again. Some chapters seem to work, but then I get the buffering screen and the movies starts again after a couple of seconds. Under Libreelec 7.0.3 everything runs smooth. Looks like there is some buffering problems or also with the cache.

Also with DTS HD Audio streams when its configured to PCM 5.1 and best match the center audio is lost. If it's configured to fixed, audio is fine. Works also fine with Libreelec 7.0.3.

I'm not an expert, so help would be appreciated. Otherwise this looks like a bug.

Regards

This won't work with LibreELEC 8.0.0 because of the changes to Kodi krypton.
These tags above are no longer in <network>, info here.

Also you don't need to put "spaces" before and after the tags.
e.g.: <memorysize>0</memorysize>

Based on what you posted above you should have this in your advancedsettings.xml file in Kodi krypton

XML

<?xml version="1.0" encoding="UTF-8"?>
<advancedsettings>
    <cache>
        <buffermode>1</buffermode>
        <memorysize>104857600</memorysize>
        <readfactor>3.0</readfactor>
    </cache>
</advancedsettings>

I would put a higher value than "3.0" for the <readfactor>, "8.0" or even "12.0" should be fine, default is "4.0".

Okay, changed the advancedsettings file like mentionned. Helped a little with the performance, but didn't solve the problems.

After upgrading to Libreelec 8.0.1 the audio problem was solved after switching the audio to HDMI an Analoge. But the chapter Search was still broken and kodi crashed.

Updated to latest testbuild (29.04.2017) last weekend, which solved the problems. 3D MVC MKV Files play now smooth again and the chapter search runs perfect again. Also Audio with regular HDMI configuration works again.

Don't now what the problem was but everything runs smooth again.
