[gentoo-user] vdpau-able ?

[meino.cramer]

Hi,

 as far as I think to know ;) (quite unsure about this), NVidia
 has introduced a new protocol (?something like this), which is
 useful for less-CPU-consumpting display of video streams.

 MPlayer (and may be other video-related applikations) does
 support vdpau. 

 First tests on my Linux-box with

    mplayer -vo vdpau <video>

 results in a movie "display" with best audio, no video at all
 and concerns from mplayer:

    [vdpau] Error when calling vdp_device_create_x11: 1
    Error opening/initializing the selected video_out (-vo) device.

 Unfortunately I have absolutely no clue for waht I have to search
 for.
 What/where I have to reconfig/recompile/install/etc. to make my Linux
 box vdpau-aware.

 Or is it such a new thing, that I better have to keep my fingers off
 that?

 Have a nice sunday!
 Best regards,
  Meino Cramer

Well, I entered this exact line above into google and the first two hits took 
me to the NVNews forum where you will find heaps of help. Such as:

-not every nvidia card supports it
-not every nvidia driver supports it
-you must run the nvidia bug reporting tool to find out if you can use it
-as of February, vdpau and xinerama were incompatible

You'll get better quality help at NVNews than here, as the nvidia devs watch 
that forum and do respond.

Thanks for point out this. I didn't know that NVidia introduced such
an important feature.

Your command didn't work for me, too. First, I checked that my video
card was capable of supporting
this new API. Then, I updated the nvidia video driver and recompiled
mplayer. For mplayer, make sure
to activate the local use flag vdpau.

Assuming that you want to playback a H.264 video, then right command should be

mplayer -vo vdpau -vc ffh264vdpau <file>

to force the selection of the HW accelerated codec from FFMPEG. Can
anyone confirm that?

This is correct.

To use VDPAU hardware acceleration you need to specify a hardware codec also
- As I use VDPAU all the time i have this configured in my mplayer config
(~/.mplayer/config) as so:

vo=vdpau
vc=ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau,ffh264vdpau,

Which lists all of the VDPAU codecs, and allows for fallback to the other
codecs if a matching codec cant be found (thats what the trailing , is for).
I have never had an issue with video in this setup.
If you wish to run that from the command line I beleve the command would be:
`mplayer -vo vdpau -vc ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau,ffh264vdpau,
<file>`

My understanding is the VDPAU works on all GeForce 8 series or better cards
(8*** 9*** 2**), I'm not sure what driver version you need to use VDPAU,
however its working for me with 180.60. However I have only tested this with
a 9600GT and a 8600GT.

As for it working with Xinerama, I can't comment - however it seams to work
_mostly_ using NVidia's TwinView which seams to provides all of the Xinerama
information to the desktop (ie. windows don't maximize over all my monitors,
just one). (As for the 'mostly' I only realy have an issue with subtitles,
particulay if I pass -ass to mplayer)

Interesting... I found on the web a similar command-line, but I didn't
understand the meaining
of the traling comma.

I think that I will modifiy my ~/.mplayer/config too.

There is also a xine-vdpau project which is necessary for vdpau
support in miro, vdr, and others.  There's a *.9999 ebuild for it in
the berkano overlay.  To use vdpau with miro, launch miro like this:

miro --set xine-driver=vdpau

The problem I'm having with it is with Blu-Ray rips.  The problem is
described here and a patch is included:

http://www.nabble.com/Re:--xine-user--No-audio-from-Blu-Ray-rips-td23121024.html

The problem is that the patch can't be applied to xine-vdpau because
it was synced with xine-lib so long ago.  I'm waiting for xine-vdpau
to be integrated into xine-lib so the patch can be applied.
