The VideoLAN Forums

When we can espect a supporting of hardware decoding of video using Nvidia's vdpau in vlc?

Yes, two students are working on it.

Merci

I forgot one more question:will there any special announcement about a merging source code into git on forum or anywhere?

Normal releases.

Quoi de neuf?

For what it's worth, I have not seen any patch, not even an informal project announcement on the development mailing list.

I'm afraid this remains 100% vaporware at this point in time.

3 students are starting to work on it on monday, so you will have to wait, if they ever succeed

Any progress on this since January? We're getting close to get out of that "ever" time constraint.

Take the libva and vaapi patches on VLC mailing lists. Works great.

Can you give the URL(s) please? In advance many thanks.

Google is my friend....

Can the instructions be posted?
Also see http://www.splitted-desktop.com/~gbeauchesne/libva/
Now to see if I can get it going...

Well, instructions are easy:
- Patch FFmpeg with H264_VAAPI patch
- Patch VLC with the vaapi patch from Mailing list or use VLC 1.1-git
- modify vlc-config with the va flags.
- compile.

Hi,

Is it possible to post here the full process in more detail, namely where to get the patches, how to apply them, etc?

Thanks

When I have time.

Well, instructions are easy:
- modify vlc-config with the va flags.
.

Would you please elaborate more on where to modify in vlc-config! I couldn't find any va related flags in the file.

Hi,

may be I can write here what I have done and you can give us some pointers....

I followed the instructions from the http://wiki.videolan.org/Git and install and compile VLC (I am not sure this 1.1 version but anyway)

And this

http://www.jbkempf.com/blog/post/2009/0 ... 5-commands

Only thing I have to differently is...

I have to change the configure to this

../configure --disable-nls --enable-qt4 --prefix=/opt/vlc --exec-prefix=/usr

Now I am not sure I have to add the lva-x11 in the vlc-config under qt4 or xvideo, while I read somewhere that VLC 1.1 GIT is already patched another question would be that
I have to install the libva (http://www.splitted-desktop.com/~gbeauchesne/libva/) from here or 1.1 GIT is already installed or not?

;;
xvideo)
cppflags="${cppflags} "
libs="${libs} -lva-x11 -lXxf86vm -lXinerama -lSM -lICE -lX11 -lXext -lXv"
;;
xvmc)

Now I install the VLC without this last two steps, it replays the AVI files but the files that are 264 coded it gives a segmentation error...

I am guessing I have already ffm264 there because I already install mplayer with vdpau support and it functions perfectly from here

http://www.avenard.org/media/Ubuntu_Rep ... itory.html

So can you give us some pointers to figure out where is this segmentation falut come from for h264 codengs.

no, it is not in the xvideo where you add those flags, but in avcodec.

It works, thanks for the tips...

720p , H264, %20 (same as MPlayer with VDPAU) load was before %60-%70....

Thx for the tips...

Ok,

It was little bit too early to celebrate...

I have a success to play one file that was crashing before but some others are still crashing with segmentation fault may be I have to add this flags to other places in VLC-config...

The file codecs looks like this for fixed fie from VLC

Stream 0
Type:Video

Language: English
Resoulution: 1280 x 534

But I can get more information if I play the file with MPlayer and it looks like this....

Main difference that I see is one identified as 'Matroska file format detected.' and the other one as 'libavformat file format detected.'..

Do I have to configure something else for libavformat?

Thx agan for the answers.

--enable-matroska

You need libebml and libmatroska.

Now I have a very stupid question somehow libva was not installed correctly by me....

When I look to vainfo, it is complaining that /usr/lib/va/drivers/nvidia_drv_video.so is not there and it is not there....

But I can find such library anywhere in the filesystem and under the libva directories...

What is the trick here?

An another interesting point when I configure the vlc with --enable-matroska option it is complaining me that is an invalid option...

configure: WARNING: unrecognized options: --enable-matroska

is this not valid for VLC 1.1 GIT?

not --enable-matroska , use --enable-mkv

If you get a chance post your complete configure

Sorry my bad,

I did not understand quickly that I have to install also

Thx again,

eveything is working fine now....

posthumecaver: Does everything works for you now?

Can you make a post of it?
