I uploaded a sample to http://www.sendspace.com/file/r5c3d7
It was recorded with vdr-1.6.0 and it plays perfectly using "xine -V xv". I'm getting same errors on vdr-1.7.7 so it's not a problem with vdr version.
There are two issues with these clips. One is a VDPAU issue. We've developed a fix and it should appear in a driver release soon.

However, even with the VDPAU fix, xine doesn't decode the clips correctly, even though MPlayer does. This indicates that there's also some problem with the DPB or picture parameters that xine is providing to VDPAU.

Is anyone else seeing out of sync audio using xine-vdpau? With the video renderer as vdpau the audio is ~1/4 second or so off the picture. It almost seems to get worse the longer the video is played but I can't definitively say that.

With video.driver=xv I do not see the issue. It's only present when video.driver=vdpau.

This happens on all different video types, not just DVD's. I'm using the nvidia driver 180.51 but it happened with previous versions as well...

I do not see this behavior when using vdpau in mythtv.

Thank you for the VDPAU fix. I'll try to get ahold of xine-vdpau developer in irc after the driver release.

Default Re: Xine vdpau announcement

does it possible to add in xine-vdpau the possibility of choice the deinterlace algorithm for SD 576i and HDTV 1080i channels ?
for example - for HDTV channels I would like to set half_temporal algo, for SD 576i channels I would like to set spatial_temporal algo

That's already the case. temporal_spatial is always used for SD, and video.output.vdpau_deinterlace_method is used for HD.

What post processing is available with xine-vdpau? I'd like to do what I can to maximize the quality of DVD's that I watch and with non-vdpau xine I was using some tvtime filters.

Thanks!

Hi, I'm not sure whether I can still report an xine-vdpau issue with this thread. It is on random rectangular blocks keep occurring when playing a Hong Kong h264 HD TV broadcast channel, either live or from a recorded file. A sample of a recorded clip can be downloaded from http://www.sendspace.com/file/gqmyge

I've tried on all combinations of GeForce 9300GS/9500GT, and Nvidia driver versions 185.18.14/190.18-beta. The rectangular blocks would start to occur after 10 to 20 secs of playing, but would disappear temporarily on scene change, and then would gradually reappear.

Thanks and Regards,
KS Ng

ksng, Can you try playing that file without using VDPAU, or in other applications using VDPAU (please also try MPlayer SW and VDPAU decoding). Does the problem still occur? Does the problem always look the same and appear in the same place in the file?

If you don't see any problems without VDPAU can you post an nvidia-bug-report, and upload the file to NVIDIA's file drop (see VDPAU sticky); I can't access filesharing sites. Thanks.

i've checked that file and found it's a DPB issue, not nvidia's one.

Hi Stephen, I've tried various players with following results:
1. ffplay - s/w decode only, plays fine, though exhausting CPU to 100%
2. mplayer, w or w/o vdpau - cannot play the file. I've logged a bugzilla report
3. vlc - plays fine, though exhausting CPU to 100%
4. vlc with vaapi (vdpau backend for vaapi) - basically plays OK without the random blocks, but there's some flickering
5. xine with xine-lib 1.1.16, no vdpau - video screen can show up but the clip cannot be played smoothly, plus lot of errors keep occurring. See attached. There's no such error when playing with xine-vdpau.

When playing with xine-vdpau, the random blocks seems always occurring at same locations.

I'm not sure if it is vdpau issue. Anyway I've uploaded the file xine_vdpau_random_blocks.ts to the Nvidia file drop.

Thanks,
ksng

No visible artefacts with mplayer -tsprobe 71850 -mc 2 (both with and without vdpau).
