[LINUX/MAC/WINDOWS] Video Post-Processing Filter support in XBMC's DVDPlayer

I would like several post processing options available. The post processing in the XBOX version of XBMC rocks. I hope that some day this will be ported to windows, without post processing i'll stick to my FFdshow and windows media player...

I just came here to find out if XBMC had any post processing abilities on windows.
I'm currently using Mediaportal (sooo unstable! even v1.0) and can't wait to switch to XBMC once TV capabilities are here, but no post processing is going to be a bummer when running xvids through my tv at 1920x1080

Are there any plans to provide any form of post processing on the windows platform ?

Cheers!

Hi all,

I am looking to move to XBMC on my main HTPC as soon as Live TV support arrives.
I'm currently using mediaportal and its reaaaaally unstable.. so looking forward to the move to XBMC.

I would like to know if XBMC can do post processing on videos ?

I currently use FFDShow under Mediaportal and have it resizing videos to 1920x1080 and adding de-noise, blur and sharpen filters.

It would be a real shame if I can't do the same with XBMC as some of my videos are the greatest quality to start with so without filters they look quite shabby on a 37" @ 1080.

Cheers!

Check this thread for scaling details -

Thanks, I have played with the scaling settings and they didn't really seem to do anything much in terms of quality.

Are there any other post processing filters such as NR, blur, sharpen etc.. ?

Cheers

No, XBMC's DVDPlayer (the video player in XBMC for Linux/Mac/Windows) does not currently offer any video postprocessing features (so today if the source video is crap then XBMC will currently display crap).

Quote:Unimplemented Features...
* Post-Processing filters to enhance visual quality and remove artifacts, etc. (port mainly from MPlayer and FFdshow?)
* SSP (Statistical-Post-Proc.), DeBlocking, DeRinging, Sharpen, Soften, ReQuantization, Auto-Luminance, Blurring/DeNoising

Feel free to submit a feature request or better yet code and submit a patch:

PS! XBMC's DVDPlayer could probably also do with a new software deinterlacing filter:

Quote:Unimplemented Features....
* Automatic deinterlace for interlaced DVDs on progressive TVs, (possible port deinterlacer from YADIF, DScaler, or y4mscaler?)

Thanks for the detailed reply Gamester, good reading.. I didn't realise DVD player was whats used for all video in XBMC windows - thats why I got confused with the PP capabilities.
I will submit a feature request, as for the moment I only know some VB6/VB.net - C/C# is my next learning mission

Thanks!

FYI; XBMC is mostly C++ with some C (like FFmpeg that is used by DVDPlayer), see:

Hello,

Would it be possible to add adjustable luma/chroma scaling in the GL shader? I mean something like option "-vo gl:yuv=2:lscale=5:cscale=5:filter-strength=<value>" in mplayer. I am using this in mplayer as a simple "sharpening postprocessing" and since it is done by the driver/GPU it has low performance impact. In my case the typical scenario is when viewing low res video but could be used to soften as well.

Also it seems that since the shaders are already used in XBMC the code change might be just minor (just my guess).

It may also satisfy some of the users asking for any postprocessing. Alternatively expose the option to load custom fragment programs (like the option customprog in mplayer)?

I use XBMC for Windows and I love it, I have a last generation ATI video card, an Intel dual-core 3.3GHz and I've a Sony 52-inch LCD panel.

I note that the video quality of XBMC, especially on SD video and DVD (but also on HD videos) is very poor when I compare it with other decoding systems, such as ffdshow, benefiting by a series of software filters to improve visual quality (denoise, sharpness, HQ scaling, deinterlacing, deblocking, etc..);

furthermore the only Media Player Classic has a series of filters (shaders) which use the accelerated graphics hardware so egregious (scaling and sharpness).

I would like to have these software or/and hardware filters in XBMC, which is an excellent mediacenter, but just like video quality/settings, which it's the main function of a mediacenter, disappoints me a little.

(Excuse me for my bad english)
