9500gt won't play vdpau
 
3 Attachment(s)
I have a Palit 9500GT Super+ 1GB, (which has DDR2), and am unable to use vdpau with it.

My m/b has a 750a SLI chipset, and using the onboard gpu, I am able to get vdpau working, though not smoothly.

I am using the 185.19 drivers.

With the command
Code:

mplayer The\ Simpsons.mpg -vo vdpau -vc ffh264 > ffh264.txt
I see a green screen, then mplayer crashes.

Code:

mplayer The\ Simpsons.mpg -vo vdpau -vc ffh264vdpau > ffh264vdpau.txt
gives no mplayer window, and just prints error messages.


I had the following set in my shell.
Code:

export VDPAU_TRACE=1
export VDPAU_NVIDIA_DEBUG=3


I also have NVRM: Xid errors in my syslog.

Is there something I am overlooking here?

It looks to me like you are trying to play an MPEG1/2 file with the H264 codec. Try using "-vc ffmpeg12vpdau" instead.

Thanks for your reply.

I realise it says "[VD_FFMPEG] XVMC-accelerated MPEG-2." in the attachment ffh264vpdau.txt, but it is in fact an H264 file. In fact, when I run mplayer The\ Simpsons.mpg, in the output is
Code:

Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264)

As I mentioned, when using the onboard video, it is able to play the file. I'll attach equivalent outputs soon.

Could you upload the sample, I am curious to test.
You possibly have a hardware problem;-(

Could you explain how you managed to get UNKNOWN as mplayer version? I ask because I thought this is not possible any more - it makes debugging very hard for me...

PS: Unfortunately, ffmpeg12vdpau will not help.

I realise I didn't say before, but with ffmpeg12[vdpau] I get no video, but do get audio.

Now, using onboard video, I get a picture with both
Code:

mplayer The\ Simpsons.mpg -vo vdpau -vc ffh264 > onboard_ffh264.txt
and
Code:

mplayer The\ Simpsons.mpg -vo vdpau -vc ffh264vdpau > onboard_ffh264vdpau.txt

Re mplayer version, I apt-get source'd version 2:1.0-svn29095-x264-vdpau-0ubuntu1, and recompiled with --enable-debug. I have Jean-Yves Avenard's repo activated. If it helps, I could try to fix this.

It might be worth pointing out that I plan to use vdpau for mythtv, which I have running at present with software decoding. It is also unable to use vdpau, but i thought it would be a good idea to at least get it working in mplayer first.


I have uploaded a sample of the video to http://www.aaatos.net/videos/The_Simpsons_Short.mpg

While I doubt it will make a difference in your case (after all, it works with on-board GPU), please understand that I can only support MPlayer svn.

Stephen will hopefully comment on your original report.

I am working on compiling svn mplayer, but I suspect the problem isn't there, as as you say, it works with onboard gpu, plus mythtv is unable to play it.

Thanks for your help.


Edit:

Ok, for completeness I have attached outputs for the 9500gt trying (and failing) to play the file with MPlayer SVN-r29184-4.3.2 (C) 2000-2009 MPlayer Team.

moliones,

It looks like (at least for the ffh264vdpau case) you've been hit by one of the bugs described in this thread:

http://www.nvnews.net/vbulletin/showthread.php?t=130690

I'm not sure if your ffh264 case is related to this or not.

We'll add you information to the list of problematic HW. Reproducing this and fixing it is one of my highest priority items. however, so far it's been impossible to reproduce...

Stephen,

I added a post in that thread.

It seems to me this is likely a hardware issue, I'm working on acquiring an 8400GS, but obviously for me and others it would be good to resolve this.


Out of interest, has anyone tried the sample I uploaded, and had it work? I assume the video is good, but it would be nice to have some confirmation.

Obviously if anyone wants any more information, or for me to try something, I'll be happy to oblige.

Apart from the fact that it doesn't show the Simpsons as the title promises, video plays fine with -vo vdpau and -vo vdpau -vc ffh264vdpau.

Yeah, I record a few minutes of the preceding program to ensure I don't miss anything. I hope no one is too disappointed.
