Clogging Video/Audio

[gkovacsp]

Bought an LCD TV recently, installed it as a secondary monitor (1360x768 pixels). Of course I use GBPVR on it.

No problem while watching LiveTV, Recordings, not so high resolution videos, but when I try to watch an HD movie, then the video and audio starts to clog. Or cough. Or I actually don't know the english word for it, but the picture jumps every now and then and the audio sounds like an old motorboat engine.

If I watch these movies via MediaPlayer and I put this Mediaplayer to this secondary monitor, go fullscreen, then there is no problem, smooth as it has to be.

I'm pretty sure you will ask the log files and I'll upload them as soon as I can, but probably someone has some idea meanwhile, or have been here.

It sounds like your codecs are not the correct ones. I changed to MPA Decoder and MPV Decoder on my system and the HD video works good now.

Good luck.

Two things I can think of... I read somewhere that a LCD flat panel looks best when it is the primary monitor. In my tests I would concur. As primary, the desktop elements: icons dialog boxes etc, look sharper and have more resolution, even though I had the LCD set to lots of color (true colur -32 bit?)

So this got me thinking that the display adapter acts differently when primary or secondary, and that means to me, the drivers, and probably the codecs act differently.

Other idea is that your codecs broke coincidentally. Remember 'Media Player' might be different than 'Windows Media Player' which uses pretty much the same codecs as GB-PVR would use. The Clasic Media Player has it's own codecs built in...

Thanks for the comments.
I went further with testing and some things I found out:
-even if I play this video on my primary monitor via GBPVR I get the same audio problem
-I uninstalled ffdshow and tried without it --> No help, couldn't see video, audio bad as before
-Installed a Matroska codec pack (CCCP) --> Video is smooth now, audio is still coughing - probably a little less.

The video is in an MKV file and contains OGG audio.

Attached are my log files, if it is a help to anyone.

All my problems were fixed on this forum before, so I'm very positive.

And Sure I used Windows Media Player and the video and audio are just fine there...

'Windows Media Player' ... uses pretty much the same codecs as GB-PVR would use. The Clasic Media Player has it's own codecs built in...

The "pretty much" part is why I think 'Windows Media Player' is not good for debugging problems with GBPVR. I had some mp3's that played fine in WMP, but not GBPVR. Iniitially, that made me think it was GBPVR's fault. It wasn't.

I had to use graphedit to get the same behaviour as GBPVR, and even there, I had to be careful when using ffdshow filters to put GBPVR on the ffdshow audio and video whitelist with graphedit to get the identical behaviour.

WMP does not play things the same way that GBPVR does. It used to, but no longer.

Set the logging level back to Debug, then reproduce the problem and repost the logs, and I'll see if anything stands out.

What audio decoders have you tried?

[gkovacsp]

I'm using Cyberlink Audio decoder, but that is for MPEG2 files only, isn't it? Where should I change the Audio Decoder?

Attached are the logs, watched a 3min James Bond Trailer with bad audio.

The first thing you should try is setting deinterlacing setting (Misc tab) back to 'encoder pass through'. Also set your audio renderer (Playback tab) back to 'system default'.
