I find when playing most XVID movies through XBMC, the video is running at like 2 FPS.

I know it's not my hardware, as I can play the video even on my laptop perfectly.
Hardware is an Intel I5 2500k Nvidia gtx 580 8 gig ram.

How do I correct this? I have a lot of xvid videos, and re-encoding isn't an option, nor should it be, considering XVID is an extremely common codec.

200+ views and not one person has any help?

The only thing I can find is that with each video that does this, the audio is always AC3 or DTS. But that shouldn't cause video problems.

debug log (wiki) needed. Also see if you can run MediaInfo (wiki) on one of the problematic files.

it can very well cause video problems. video is synced to audio, and if you're outputting the ac3/dts wrong, sync will be wonky. e.g. passthrough when no passthrough capable receiver is hooked up through appropriate means.

Ned Scott, here is a copy of the log, and the media info for the file being played that stutters.

Spiff, ok thanks. I think that may be the issue. How do I fix this without re-encoding?
I thought coming from a pc, the audio is just converted to stereo and shipped out that way.

I have my PC hooked up via HDMI to my tv, and the tv audio output to my home theater receiver. Which is incredibly old LOL.
Would upgrading the receiver to something that supports AAC/DTS etc fix this problem?

quixand · 2012-11-13, 17:33

Transcoding the file into AC3 5.1.

If people have such problems with AAC audio types, why use them?

**spiff** · 2012-11-13, 18:48

it looks very much like what i suspected. go to system -> audio output. untick 'dts capable receiver / ac3 capable receiver'.

That did it. You sir, are a genius. I thank you.

I know my receiver is an old crappy one, but it does say it is DTS capable. So I checked DTS available receiver. The other video that WAS stuttering that had DTS audio stopped stuttering, but no audio comes out. Any idea behind that one?

It's PROBABLY my home theater. It's REALLY old, and I need to upgrade it, I just haven't found a good boxed HTC in a reasonable price range.

**jjd-uk** · 2012-11-14, 13:05

The problem is likely that the audio is being passed through the TV and the TV probably doesn't support passthrough of AC3 or DTS from an external source, in this case HDMI. Unticking "dts capable receiver / ac3 capable receiver" means that XBMC will now be decoding the AC3/DTS tracks to PCM which the TV can passthough.

I'm guessing your receiver doesn't support HDMI which is why you have it setup this way, but if you can you might be better off connecting direct from the PC to amp by SPDIF.
