Yes, that makes perfect sense, given it's an MKV file.

I believe this is a known issue. We already have clips that reproduce this problem and are working on it. I don't think we need anything from you, unless we say the issue is fixed in some future release, and you still see the problem then.

Hi Stephen,

Thanks so much for being so available on the forum to answer all these questions-- thought you might want to take a look at this:

http://svn.mythtv.org/trac/changeset/19227/

It's a small tweak to libavcodec to fix rendering issues with MPEG-2 material. I know that some of us have seen it with mplayer as well, so this may help for the next patch set.

Now, if I might, a quick question for myself. I have the new ASUS P5N7A-VM 9300 IGP board. I have had no luck whatsoever getting any sort of VC-1 acceleration with this board. I may have misunderstood the original compatibility list, but should I be getting VC1 with this board? If not, perhaps it's just a small issue with the driver?

Thanks!

Sure thing; it helps us to know what problems people are seeing.

I *think* that should work, although sometimes it's hard to tell given the way marketing names work. If you get error 14 (VDP_STATUS_INVALID_DECODER_PROFILE) when creating the decoder object, it's not valid HW, otherwise it most likely is.

Anyway, a number of people have apparently been having problems on systems using 256M graphics RAM (not system RAM). On an IGP board, there may be a BIOS option to bump the video RAM size up to 512M, which might help you.

Otherwise, please follow the VDPAU debug instructions in the sticky, and we should be able to tell what the problem is from the debug spew.

Stephen,

Thanks. It is indeed the dreaded error 14. I had bought the motherboard hoping to get offload of VC-1, but that's just the way the cards fall sometimes. Perhaps (if the IGP variety of the 9300 allows it) I'll see hardware offload of VC-1 at some point in the future. Anyway, at this point it's a non-expanding group of my titles (stuff I pulled off of my HD-DVDs) and all the new stuff is generally profile 4.1 h.264 from my blu-ray disks. So, no worries, I'm awfully satisfied with VDPAU so far and if the VC-1 accel comes, it comes. Thanks for your time.

Never mind about the below. I had Composite turned off in my xorg.conf.

I have an nVidia 8400GS (256M). I used the mplayer-vdpau-3139462 package to build a VDPAU patched mplayer. This is an Ubuntu Hardy system.

I installed the 180.11 driver and then compiled mplayer.

I then attempt to play an mpeg2 file. I get great sound but the image is a green screen. Below is attached
the output of mplayer with the VDPAU_NVIDIA_DEBUG (etc...) set as instructed in the sticky. Also an nvidia-bug-report.log. The mpeg file I was attempting to play is the mpeg file linked to by the README.txt file in the mplayer-vdpau-3139462 package.

Also, if i use -vc ffmpeg12 instead of -vc ffmpeg12vdpau I *still* get a green screen when using the compiled mplayer. My system installed mplayer works just fine (but without VDPAU of course).

Thank you.

2 DVB-T files one plays but jumpy, the other plays at 50% speed.

Good news: The next driver release will fix the H.264 reference frame limits. We will support level 4.1 (or very close to it) in all cases[1]. The decision of how many reference frames to actually allocate is up to the client application (a minor VDPAU API change). We'll naturally release updated MPlayer patches to go with this change.

[1] Some very unusual resolutions on some subset of GPUs will end up supporting 1 less reference frame than full 4.1 conformance requires. In practice, you're quite unlikely to spot this limitation in the field. Fixing this will take some more work, although it may happen eventually.

Stephen-

Thanks to you and the nvidia team for listening to our nags and requests.

I realize that this initially was not a priority at all, so I appreciate you listening to what it is that the users actually want and making it happen.

yes this is good. Ill keep checking back to see when the new driver is updated.

Stephen, if you dont mind me asking what is the projected timeline for this driver to come out of beta? Are you on a project plan or is it done when its done?

Just curious.

Mitchell

I really can't comment on driver release schedules. Don't worry, I imagine it won't be too long of a wait though.

This is wonderful. I know lots of us would have been regularly hitting that limitation.
