[PATCH] Hardware deinterlacing for both software and DXVA2 decoded material

Nice !

Installed the new build & it works like a charme! Great work and thank you!

Could it be that the information about CPU Usage when pressing "o" while movie is playing is broken?
It always shows me 8.7%, whether DXVA2 is activated or not. No difference.

Task Manager shows me ~50% when DXVA2 is on and ~80% when DXVA2 is deactivated, so I guess DXVA2 is working.

I also have a high CPU Usage when XBMC is in idle mode (~50%), is anything known about that?

Anyway, nice job isidrogar!

Must be a problem with the nightly builds. Ever since I started using the June nightlies I get 0% CPU utilization.

The patch works great but makes XBMC unresponsive on exit. I'm using Win7 32bit with ATI5450 on an old-ish AMD processor.

Hm, exit works as it should. Closes directly.

I installed this version from the first post:
XBMCSetup-20110618-c813ba0-dx.exe

Sorry, I don't really see any difference when playing back videos? How do I know the deinterlacing is working? Is there something I need to do to enable deinterlacing? thanks.

When playing back a file, go to the video menu (that film roll at the bottom) and set deinterlacing to auto.
you can even switch the different modes, when playing back a file (an interlaced file).
You will see the difference (bad deinterlacing will show vertical lines).

Try the installer posted on page 8, it fixes some problems when playing back files with Ati cards.

depends... the patch should be rebased to the latest xbmc/master branch as a lot of deadlock situations have been resolved recently.

Thanks. I installed the installer on page 8 which is compiled June 26 2011. I didn't really notice any difference when compared to the June 06, 2011 nightly build I was using on my AMD E-350. Probably the AMD driver deinterlaces on its own?

One strange thing I noticed is that after installing this version, it always show cpu usage as 0% on whatever I watch, regardless if it is sd videos or 1080p hd videos.

Look at post 82 http://forum.xbmc.org/showpost.php?p=825...stcount=82

Thanks for your comments!

If anybody is having unresponsive/freeze/locking problems during live TV viewing, at the end of DXVA2 decoded videos or during exit here is an updated installer.

I have modified the way Direct3D rendering surfaces are managed in CDecoder and CProcessor in order to avoid some problems of accessing to already relased pointers.
