I am running the lastest SVN as of last night 8 pm and I am having the same issue as the poster earlier where everything seems to be blue when enabling vdpau explicitly. Is that a configuration error on my part or a bug?

Thanks

changed: vdpau must now be explicitly selected from gui options to be active

Looks like setting the renderer to Auto will not use VDPAU anymore.

well that answers that at least however the stuttering is my biggest issue

Latest is not a version... Wink

SVN builds move so fast that sometimes between checking out a new SVN and compiling it for install another one is available Wink

hey guys... just compiled the newest svn (says r1414 in xbmc's info but i believe it said 19297 after svn checkout).... made sure to get all build-dep and the nvidia vdpau headers before compiling, running nvidia's 180.44 drivers and compiled with vdpau enabled and pulse disabled.... still 1920x1080 @ 60 hz, vdpau selected and lots and lots of stuttering... tried a 720p vid i had and the kill sample... new logs here:

What fps does you video have ?
If you try to play a 25 or a 24 fps movie on 60hz you SURE have a lots of stuttering.

720p vid getting about 21-22fps with consistent drops and the killasample getting 16-18fps with tons of drops... but i should be getting 25 consistently should i not? a few builds back upon my first 180.44 driver install i was getting smooth video playback under vdpau for most of my 1080p and 720p vids at 25fps until a few videos later it crashed and i haven't been able to get that back since...

What's the latest with 8400GS? Are they still buggy as hell with VDPAU?

EDIT: I know VDPAU has nothing to do with xvid/divx/rm etc. but will this still play, just relying on CPU for processing instead?

720p H.264 is reported working with 8400GS (pci) vdpau.

1080p h264 works on my MSI NX8400GS 512 MB video card (PCI-E).

What should I try next?

I have the exact same issue. Did you ever find a solution?


- alanwww1 - 2009-04-07 20:07

New Nvidia driver came out today with interestinf VDPAU improvements:

Code:
#  Fix VDPAU to eliminate some cases of GPU hangs when decoding H.264 video on G84, G86, G92, G94, G96, or GT200 GPUs, and supplying a DPB missing some reference frames.
# The VDPAU presentation queue now syncs to VBLANK in the blit path. The environment variable VDPAU_NVIDIA_SYNC_DISPLAY_DEVICE selects which display to sync to when TwinView is enabled; see the README for details.
# On systems using integrated graphics, VDPAU now uses system RAM instead of video RAM for many purposes. This should prevent "out of resources" problems in most cases, even when the video RAM carve-out is configured as low as 128M.

Great work form Nvidia and Motd2k ! Smile

sounds interesting.... just installed them however they dont fix my problem Sad... doesn't seem to be offloading any used memory to my ram either (but vdpau isn't working right anyway so who knows what that means).... still getting lots of stuttering/drops from 1080p and 720p video.... new logs using 185.19 below

not sure what it means, but this seems to be consistent in my xbmc.log:

14:21:33 T:2784562064 M:1398951936 ERROR: (VDPAU) Error: UNKNOWN(159752824) at VDPAU.cpp:933

I tried the new drivers.

I can not see any visual improvements in playback smoothness.

I have a complete smooth playback with SW decoding, but with vdpau i see frequent micro stutering.

Always loved XBMC, and then stumbled on this thread today, great job guys, looks really exciting...

Also since the announce of the ION platform http://www.engadget.com/2009/04/07/acer-launches-first-nvidia-ion-based-nettop-aspirerevo/
this would make for an amazing HTPC.... however do you guys think that the atom will be enough ?
