Hello,

 

I’ve written an email to Haihao Xiang regarding the “no deinterlacing” bug
on Clarkdale a week ago and he answered today. He will check this issue.
I’ll hope he can fix it. Will the extended vaapi-ext deinterlacers (temporal
or spatial I guess) also be available on Clarkdale platform? I tried the
extended DXVA hardware deinterlacing on Windows today and it worked fine on
my CoreI3 Clarkdale Laptop CPU J

 

Best regards

Atech

Hi!

 

Please note that you need to increase microversion of intel_vaapi driver so
xbmc gets deinterlacing turned on:

 

See the end of my guide: http://forum.xbmc.org/showthread.php?t=114368

 

Try it like that. For Sandy Bridge it works.

Hi,

I tried the vaapi master and ext-libary including the vaapi-intel-driver
from your repository.

My Hardware:

- intel Clarkdale Core I3 540 / I5 661 (I have two different systems)

- H55 chipset

- TV over HDMI @ 50Hz

Software:

- Arch Linux 64 Bit with:

- Kernel: linux 3.1.9-2 (base) - Xorg: xorg-server 1.11.3-1 (xorg) - Grafik:
xf86-video-intel 2.17.0-2 (xorg-drivers xorg) - libva-ext 20120110-5
VAAPI-ext library for intel cards - vaapi-intel-driver 20120110-2 Intel
backend for VA API: 1.0.17.pre1 (patched to version x.17-pre for xbmc
interlacing option) - Alsa: alsa-utils 1.0.24.2-3 - vdr: vdr 1.7.23-1 -
SoftHD: vdr-plugin-softhddevice-server-git 20120120-1 - Streamdev:
vdr-plugin-streamdev-server-git - ffmpeg 20120111-1 - xbmc-git 20110120-1 

VAAINFO:

libva: VA-API version 0.32.0 libva: va_getDriverName() returns 0 libva:
Trying to open /usr/lib/dri/i965_drv_video.so libva: va_openDriver() returns
0 vainfo: VA-API version: 0.32 (libva 1.0.16.pre1) vainfo: Driver version:

VAProfileH264Baseline :VAEntrypointVLD VAProfileH264Main :VAEntrypointVLD
VAProfileH264High :VAEntrypointVLD 

and also vaapi-master branch 

I checked the newest XBMC-GIT version with vaapi-ext deinterlacing support,
a new vaapi plugin for the vdr (video disk recoder from Klaus Scmindiger to
watch and record TV) with vaapi deinterlacing support and the xine-vaapi
branch form Edgar Hucek.

In addition I checked all available options to select the bob deinterlacer,
but every time I don't get interlace output.

XBMC shows me a doubled framerate count but no deinterlaced video.

Also mplayer-vaapi and VLC with vaapi support don't show any hardware
deinterlacing. To get more informations, I shared my expierences with other
vaapi users and they told me as well that they only have deinterlacied
output with the newer Sandy Bridge chipset only.

Is it now (or in the future) possible to get deinterlaced output with the
first "Core Ix Clardale" prozessor family? Or is there any difference
between the Clarkdale/Sandybridge vaapi version one should regard, to get
the deinterlacing working?

Regards

Atech

Hi Atech,

same problem over here. I am on vaapi-ext and latest xbmc. I can select Bob and
Bob (inverted) as deinterlacers in xbmc. With MPEG2 material deinterlacing
doesn't work at all. With H.264 video it seems to deinterlace, but video is
stuttering and I have lots of frame drops.

Hardware: Core i3 530
Software: Ubuntu 11.11 x86 minimal with latest xorg stuff (edgers:ppa) and
vaapi-ext branch for libva and intel-vaapi

Regards,
Christoph / Flachzange

Hi, 

   I know what is the problem. For some reason, the native pixel format
for MPEG-2 decoding on Clarkdale is I420, however the input pixel format
of deinterlacing is NV12 in the driver, so the driver doesn't support
deinterlacing for MPEG-2 on Clardale. We will try to fix this issue but
don't expect it too soon.

BTW you can send all VAAPI related mail to libva@lists.freedesktop.org
as well.

Thanks
Haihao

Hi  Christoph !

For the stuttering problem it is cause by lack of shader horse power to use
HQ upsacling AND deinterlacing together.
Please try to set the upscaler from auto to "bilinear" or even "nearest" at
the worst case.
Also if you are using xbmc in a composited environment please turn off all
compositing or even try to run xbmc in a separate Xsession.

If that does not help, you probably will never have it working stutter-free
with Clarkdale.

Cheers,

Attila (Team XBMC)

Yes, I noticed this in the meanwhile. GPU top showed me 100% usage :-)

It already was bilinear, but even nearest does not help

No composite environment, but openbox window manager

Yes probably, even with mplayer no chance (68% framedrops)

Thanks!
