@Elan.. Thanks for that (and the latest release), I don’t have a massive amount of 1080i material but thought I’d mention it just in case

@jms_uk, in XBMC on the Xbox the de-interlace filters are disabled by default, you need to enable it manually from the OSD while playing the video. I understand the reason for this is that the auto-detection routine used in order to detect interlaced video is far from perfect which causes it to activate on many progressive videos as well which is not good at all as de-interlacing a video that is not interlace will make the quality of it really bad.

Maybe the de-interlace filter is disabled by default on OS X as well?

@Elan,

I don’t know if this is of interest, but I’ve noticed that some 1080i MPEG2 content is not de-interlacing correctly on playback. I’ll try and get you a sample if possible, but thought I’d give you the heads up..

@bisebusen: i am pretty sure i am able to do that already.. have some DVD (tv-show) images and they work as far as digital sound goes.. with mixdown they would even play at normal speed, with sound

If the “skiploopfilter” does not do anything to performance when you try to enable it then you must not really have enabled it, because inloop decoding is very CPU intense (so keep an eye on your CPU activity), as “skiploopfilter” skips the inloop deblocking process when decoding H.264 it make a significant difference.

You would also notice a visual quality difference when the skiploopfilter is enabled, that is worse quality.

However if you use lavdopts=skiploopfilter=bidir (in MPlayer) then only the deblocking of b-frames will be skipped which is a good compromise as you then will hardly notice any blocking artifacts or quality degradation. I suggest that you try it with MPlayer for OS X just test.

I assume this would translate to “skip_loop_filter = AVDISCARD_BIDIR” for FFmpeg?

@cyantist: Funny you should mention that, because I’ve been experimenting with skiploopfilter, doing “skip_loop_filter = AVDISCARD_ALL”. I haven’t observed the slightest benefit from the “bird scene” in Planet Earth, so I’m a bit confused, but also a bit drunk.

I also have to add that even though I’d never use it, I think the ‘-skiploopfilter’ option would be a great feature to add. It would at least give people the option and choice to use it if they had to. Even though a 720p stream without the filter would most likely look better, that might not always be an option.

Options are good. It makes life easier to live on the bleeding edge.

@Weavus,

Which option do you use to exit using the Aeon skin? I remember there being a few options such as “Power”, “Restart”, “Reboot”, etc. I had the most luck using “Reboot” (which I’ve since renamed “Shutdown”). It exits properly, not actually rebooting or restarting as you would think. On closer inspection, the command given by “Reboot” was in fact XBMC.ShutDown. You can find all of this in the file Homescrollers.xml in the /skin/Aeon/PAL/ folder. Customize at will, just remember to backup the original first. After a little investigation and experimenting I’ve gotten my Aeon skin tweaked just the way I like it now.

Playing with XBMC over the last little while has given me a new appreciation for the xml language. I can only imagine how the coders feel…
