Hi, and big thanks to the nvidia people for supplying vdpau. Your recommended samples and Apples 1080p demo's play just fine on my machine. However, trying this high-bitrate sample crashes mplayer:

http://rapidshare.com/files/82525583...ampla.x264.mkv

Input #0, avi, from '/home/vdr/video/killa.sampla.x264.avi':
Duration: 00:00:22.91, start: 0.000000, bitrate: 35098 kb/s
Stream #0.0: Video: h264, yuv420p, 1920x1080, 23.98 tb(r)
Stream #0.1: Audio: ac3, 48000 Hz, 5.1, s16, 448 kb/s

I've converted it to an avi but it still fails the same way. It plays with -vc ffh264 but not at full speed. I follow this with great interest and have tried all 180.xx versions and all your mplayer patch versions.
BTW: 256MB video RAM.
And one other thing. I run mplayer directly under X and have no window manager and if I don't start mplayer with -fs, all video samples show just random junk in correct resolution. Scaling to 1360x768, it looks just fine.

The M3N78 Pro has the following BIOS options to increase the shared video memory, could you check if you can find these ?

Under Advanced>Chipset>

iGPU Frame Buffer Control [Auto]
needs changing to [Manual]

Frame Buffer Size [256M] needs changing to [512M]

Using VDPAU
With metacity cpu0 utilization is always under 1% max 2% , cpu1 0% (fantastic !! ).
With compiz or kwin (composit enabled) cpu0 always is over 74% and 1% max 2% cpu1.
Not Using VDPAU
under metacity cpu0 20% max 23% and cpu1 6% max 15%
under metacity cpu0 45% max 50% and cpu1 30% max 36% under compiz.
Is this something known from nvidia ?
I am always under compiz-fusion, and I never succeed in really using vdpau, I have to try from my ratpoison WM then...

Looking through the device IDs I had noticed a while back that the 8800 GT of mine has an ID (0x0611) that is inline with the 9800's that were released at the same time that I bought it back in April. This differs (0x0602) from the original 8800 GT's that came out last year.

I figured there was prolly some small difference but wasn't all the interested at the time. Now I'm thinking that the extra video decoding features of the 9800's might be that difference and included in the second revision of the 8800 GT's.

Hi. Thanks for the clip. I've reproduced the issue. We'll look into it.

Thanks to you , Stephen. That clip seems to be the benchmark on a lot of forums and so far no one has managed to play it on linux without at least dual 3Ghz. If you made that work on vdpau there would be a LOT of talk about it.

I think you negelected to see the previous posts on this topic. I wasn't saying that people didn't need to deinterlace. I was asking about why *I* would need to deinterlace when I am playing an interlaced video on an interlaced display (someone had suggested that I needed to deinterlace; I was asking why I would need to).

My original question, which has been obscured by this tagent into deinterlacing, is this: is it considered a problem that, when using VDPAU, I experience terrible tearing when playing an interlaced video on my interlaced display. Is this something nVidia is aware of? Are they interested in bug reports about this? I haven't seen any discussion about this which is why I am asking.

@Senor Hubris,

Tearing is a known issue in some X configurations right now. This will probably end up affecting interlaced output worse than progressive output, since the frame buffer is always "progressive", and hence tearing will affect multiple output fields in subtly odd ways.

You could try disabling the X composite extension to see if that works better for you (also disable SLI and any desktop rotation).

Hey Stephen I have a new error that no one else has (or so I think)! The file to test it is easy and legal to get too. You can get the file here: http://blip.tv/file/get/Jupiterbroad...0Review722.mp4 I used ffh264vdpau and the file started okay for around 44 seconds but then crashed.

Error:
Code:
vdp_presentation_queue_block_until_surface_idle(3, 23, -)
VDPAU nvidia: Error detected 3 438 
VDPAU nvidia: Backtrace:
01: /usr/lib/libvdpau_nvidia.so [0xb5c2fd0e]
02: /usr/lib/libvdpau_nvidia.so [0xb5c2fdd9]
03: /usr/lib/libvdpau_nvidia.so [0xb5c3e5db]
04: /usr/lib/libvdpau_nvidia.so [0xb5c3e63b]
05: /usr/lib/libvdpau_nvidia.so [0xb5c39a52]
06: /usr/lib/libvdpau_nvidia.so [0xb5c3519a]
07: /usr/lib/libvdpau_trace.so [0xb5e240e1]
08: ./mplayer [0x80b6aae]
    -> 2
Error 2 at libvo/vo_vdpau.c:1074
Hmm I think this could be just a file problem. If it is just a file problem it would be nice for it to handle these problems instead of crashing. WIthout VDPAU there is a little error in the video but it doesn't crash. Anyways...

Thank you for the update Stephen.

When I disable Composite I get a green screen whenever I play anything. I'm not using SLI or
desktop rotation.

You're probably hitting a known bug.

Do you have 2 displays plugged in, or do you have 2 X screens configured? Try not doing either of those, or using a different display connector on your graphics card may help, or even plugging in another unused display to another connector. Hopefully we'll get this resolved soon.
