(This post was last modified: 2015-09-23, 17:53 by zag.)
For example :
screen resolution : 1920x1080
video file format : 640x360
XBMC will force upscaling 640x360 to 1920x1080.
It's good but I wish to have an option to disable upscaling and output
with its native 640x360 resolutioin.
sometimes I use windows + KMPlayer, when playing video file, KMPlayer will output native resolution, and it looks better than upscaling.
I also use XBMC for Xbox, set to 480P only to disable upscaling,
but since 1080p is more popular these days, XBMC for Win/UBUNTU will be set to 1920x1080 screen resolution, and force upscaling video output,
but some low-resolution video become blurred if upscaling.
Is it possibe that XBMc can do native video file resolution output like KMPlayer do ( eg. DVD ISO output with 720x480, not upscaling to 1920x1080 ), and switch back to screen resolution ( eg. 1920x1080 ) when stop playing and back to XBMC desktop ?
or user can have an option eg. advancedsetting.xml
if file name string with "480p" character, output with 480p resolution ?
so user can rename the video file name to match the output.
thanks !

Thanks for your reply, I understand it now.
If I set XBMC 1080 and press "select" during play to switch resolution, there will be a "native" resolution but only small center area if the video is lower resolution.
My Sony KF50XBR800 seems did upscaling better than XBMC did....

I'm surprised your computer allows output at 640x360 resolution.
I suspect it doesn't, and you're actually getting it rescaled twice.

This is come up a few times in the past, would be great for those with external scalers.
including me ;-)
so another +1

Bump for Eden? I would love to see this so I can have my receiver do all the work in decoding the audio (Bitstreaming) and if this is implemented, use its superior scaling.

I think something like that is not really possible (or at least not practical):
- your pc has to change the output resolution every time you watch a different movie (would look ugly i guess and take wuite some time)
- how should the menu parts be displayed, eg.: you watch a movie in 720x480 and than you want to go to the menu (the movie keeps playing in background), xbmc would either have to scale down the menu from fullhd to your resolution (or even a different aspect ratio!!!) or has to change to fullhd in that moment again. i don't think, that something like that would be practicle ...
a better thing would be to work on the upscaling techniques (using different algorithms, adding support for add in cards if things like this exist, ...)

Switching TV resolution will be absolutely essential if XBMC is to ever support proper interlaced output in the future.

why do you want to have interlaced output? it is simply a question of which instance does the upscaling or deinterlacing -> tv or a/v receiver or external upscaler or pc with xbmc.
i don't see a proper possibility that it is done outside of the pc running xbmc, but if anybody has an idea, i would love it ...

All HDTVs and most home theater receivers deinterlace video and do so at MUCH greater quality than XBMC can. Not to mention it would SIGNIFICANTLY lessen the load on PCs.
I was thinking about having to render the interface at lower resolutions and different aspect ratios, the upshot to this is XBMC skins must already support all those odd resolutions and AR's anyways so the work there is done. It might not look as nice as an interface rendered at 1080p, but it wouldn't be as bad as you think.

for me it simply brings to much problems that cannot be dealt with, but maybe that is a matter of taste.
