vdpauh264dec plugin not recognized by playbin

[Robert Szelepcsenyi]

Thanks to all who replied to my post.

I have made some progress, but stiall I am unable to get HW accelerated
playback of h264 video in webkit.

I changed the rank of vdpauh264dec to primary (I had some problem with
marginal, which I haven't investigated yet). Now playbin2 can autoplug the
plugin and play a h264 video. I have also tried totem, which is based on
gstreamer. Totem can also open and play h264 files with HW acceleration. So
far no problem.

However, I can't play h264 files in webkit. Just nothing happens. I don't
know, how to debug it. Do you have any idea what to look at?

Should I recompile webkit? I thought this was not necessary.

rank=0 elements are not auto-plugged. You need to change it in the code
to have e.g. GST_RANK_MARGINAL
