...and I think you mean "inloop" (or "in-loop") filter, not "loopback" filter.
XBMC for Linux uses XBMC's own in-house developed video-player that we call "DVDPlayer" that is based on FFmpeg.
PS! FYI; Elan tested disabling "inloop" filtering for FFmpeg inside DVDPlayer in XBMC for Mac OS X and it did not yeild much speed gain (only one frame per socond or so IIRC).

I recently discovered that adding lavdopts=skiploopfilter=bidir, or lavdopts=skiploopfilter=all, or lavdopts=skiploopfilter=nonref to the mplayer.conf file turns off different deblocking modes in MPlayer.
My question is: does this affect all codecs or are there only certain ones that this affects? Ideally I would like to have this setting only affect H.264 playback, and all other video playback be unaffected...
Also, is there any way we can get this added to the GUI, so the setting can be changed very quickly? This setting drastically improves the playback of H.264 files encoded with the deblocking filter with various changes in quality. the "bidir" setting seems to look the best, while still reducing dropped frames by more than 50%!!! If the file has no deblocking, then it is more likely it will playback better, with no reduced quality.
If this were a GUI setting...
Skip Deblocking:
+ None (Default)
+ BiDir
+ NonRef
+ All (BiDir + NonRef)
Easy as that... half the H.264 playback issues solved with a simple little setting provided conveniently to the user! Let's push this!

I'm pretty sure I meant "lavdopts", just like the thread title... IDK... maybe they both do the same thing, but a Google search of "lavdopts" yields 450 results, and "lavcopts" only yields 4.
.conf files for each movie is a little overboard IMO. There's no way to only have this turned on during H.264 playback? I'm sure there's a way -- anything is possible!

Apologies. I originally thought that was a typo as I'd never seen it before. A little research shows the lavdopts are just additional libavcodec debugging parameters. According to the man page, this parameter only applies to H264.

So, technically, this feature would be a valuable addition to the GUI, wouldn't it? How can we formally make a feature request? I'm sure this wouldn't take any time to program, and would be really beneficial for fellow Xbox+XBMC users...
Sorry if this has been asked before...

Hi,
Thank you to all involved in XBMC - it's amazing!
I've noticed that my mp4s don't look as good (more pixilated) when playing through xbmc as they do when I'm just using the apple tv - is this a setting that I need to modify? Divx, etc all look the same as through nito tv but the difference on mp4s is quite noticeable.
