** Description changed:
Beginning with Ubuntu 14.04 mesa will be shipping with vdpau drivers
that can be used by e.g. radeon / radeonsi OSS drivers. This allows low
power systems, like AMD E350, Kabini and so on to playback Full HD h264,
vc1, mpeg4 and mpeg2 videos.

It sounds reasonable. Please could you subscribe to bug reports and

FWIW, here's a quick comparison, bob vs temporal deinterlacing:

Notice the increased sharpness in the second image.

I've got to admit, i'm struggling to see the improvement, and I *want*
to, agreeing with the request of this bug.
But perhaps the conversion to jpeg is wiping it out? Should be using a
lossless capture there, I reckon.

Hint: Make both fullscreen and check the power supply lines.
Bob clearly has artifacts, e.g. line is not even continuous
differentiable vs temporal: all fine

ok, i *can* see the improvement if i view the images at full size
switching between browser tabs (which the site's own page doesn't seem
to let you do, bizarrely; initially i'd just thought they were SD
captures). Yes, 2nd image is better; but *still* it would probably be
better reflection if not
A fix for this is only showing the top or bottom fields, but that means
losing half of the horizontal resolution.

Conversion to .jpg is probably destroying it. But yes it's very visible
in mostly static images. 'bob' deinterlacing is called that way because
objects bob up and down when top and bottom fields are shown
alternately. The horizontal resolution of each field is only half a
frame, so vertical
There are other advanced methods, e.g. combining temporal information
with spatial information, that you find in the nvidia proprietary
implementation for example.
Also intel tries to get something done in their MADI and MACI
implementations, but with only one forward reference i am not so sure
This bug was fixed in the package mesa - 10.1.0~rc3-0ubuntu1
