I can't seem to use Lanczos or Sinc upscaling anymore in beta2. In beta1 at least i was able to solve it with an advancedsettings.xml like this:

Code:

<advancedsettings>
   <videoplayer>
        <highqualityupscaling>1</highqualityupscaling>
        <upscalingalgorithm>8</upscalingalgorithm>
   </videoplayer>
</advancedsettings>

But since beta2 it does not work at all. I see it from the picture quality and also from th cpu utilization.

How can i get it back ?

Thanks in advance !

guisettings.xml

guisettings.xml

I tried it there also with these settings:

Code:

<videoplayer>
        <adjustrefreshrate>true</adjustrefreshrate>
        <highqualityupscaling>1</highqualityupscaling>
        <synctype>0</synctype>
        <teletextenabled>false</teletextenabled>
        <upscalingalgorithm>8</upscalingalgorithm>
        <usedisplayasclock>true</usedisplayasclock>
        <vdpaustudiolevel>false</vdpaustudiolevel>
        <vdpauupscalinglevel>false</vdpauupscalinglevel>
    </videoplayer>

With the same settings beta1 worked but not beta2.

I'm having the same problem as well with beta 2 (tried guisettings and advancedsettings) and no change (can tell by CPU usage)...

Also once this does get fixed, which algorithm number corresponds to bicubic? I don't have enough CPU for the others...

I've created a ticket for the problem:
http://trac.xbmc.org/ticket/8096

[alanwww1]

I think i found the problematic commit. Somehow xbmc wrongly reports that the renderer is not supporting the upscaling method. (note that i had used the normal glsl renderer without any vdpau) Here is the line in the log:

Code:

WARNING: CLinuxRendererGL::UpdateVideoFilter - choosen scaling method 8, is not supported by renderer

Here is the problematic commit: http://trac.xbmc.org/changeset/25047

@elupus Could you please check ?

I tested a revision just before this commit and it was working beautifully. So surely this is the cause.

Thanks for the investigation & bug report.
This is annoying. PQ is noticeably worse with beta2 because of this.
I hope there is an easy way to upgrade the code without having to release a new beta!
[I guess this is what betas are for]

[alanwww1]

Checking the code i found out that hq sw upscaling is totaly disabled. I enclosed a patch in my original ticket to re-enable that.
Please Devs put back at least the possibility to use these scalers at least with the advancedsettings.xml It is just removing TWO lines in the code!
This really should be in Camelot final so that people won't have to recompile xbmc for using this great option.

[freddyflinty]

Is there any way to check if this has been fixed in the newly release Camelot RC1? I'm so happy with LIVE right now that I'd hate to go back to nightly PPA's or compiling myself...

It doesn't seem to be in RC1. Not from the notes on the bugtrac site.

Meanwhile great devs Bobo1on1 and Elupus picked up the problem and solved it.
The solution is also backported to Camelot release branch. This means that it will be working in the final Camelot release. All you guys have to do is put the following code into ~/.xbmc/userdata/advancedsettings.xml

Code:

<advancedsettings>
  <video>
    <highqualityscaling>1</highqualityscaling>
    <highqualityscalingmethod>8</highqualityscalingmethod>
  </video>
</advancedsettings>

Thanks for the Devs for making the Camelot release even better.

ps.:
Note that 7 is for Bicubic (SW), 8 is for Lanczos (SW) (the best quality in my oppinion), 9 is for Sinc (SW)

Thanks for the great work in getting this fixed & put back in, everybody.

[freddyflinty]

I second that. THANK YOU!

Can you please post the <videoplayer> section of your guisettings.xml?

I think the options I have in there are preventing this from working.

Thanks.

Note that the fix is only in svn yet. It will be only available in rc2 or in the final version.

Or you built from svn ?
