[xfn]

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

[Jean-Baptiste Kempf]

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?

[Rémi Denis-Courmont]

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.

[Jean-Baptiste Kempf]

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

[ull]

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

[Jean-Baptiste Kempf]

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

[Repto]

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

[Repto]

Google is my friend....
http://www.jbkempf.com/blog/post/2009/0 ... and-nVidia
Can the instructions be posted?
Also see http://www.splitted-desktop.com/~gbeauchesne/libva/
Now to see if I can get it going...

[Jean-Baptiste Kempf]

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

[Jean-Baptiste Kempf]

When I have time.

[ksng]

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.

[posthumecaver]

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.

[Jean-Baptiste Kempf]

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

[posthumecaver]

It works, thanks for the tips...

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

Thx for the tips...

[posthumecaver]

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
Display Resolution: 1280 x 534
Frame rate: 24

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

[mkv] Track ID 1: video (V_MPEG4/ISO/AVC) "x264@High Profile L4.1 720p", -vid 0

[mkv] Will play video track 1.

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.

[Jean-Baptiste Kempf]

--enable-matroska

You need libebml and libmatroska.

[posthumecaver]

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?

[mc2man]

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

If you get a chance post your complete configure

[posthumecaver]

Sorry my bad,

I did not understand quickly that I have to install also

http://www.splitted-desktop.com/~gbeauc ... pau-video/

Thx again,

eveything is working fine now....

[Jean-Baptiste Kempf]

posthumecaver: Does everything works for you now?

Can you make a post of it?
