Bug Description

With the release of a package with the official nvidia tegra drivers in Quantal, I hoped that I will able to read my video files on my ac100 with hardware acceleration (as with original Android).

With mplayer provided by default with the lubuntu distribution, the whole system freezes for each format I tried (mpeg2, H264 ...)
I would try VLC (that support OpenMAX), but I doesn't find how to rely it with the NVidia implementation (given by libnvomxilclient.so I suppose)

I don't know if I had completly miss the good way to read a video with Quantal, or if I'm on the right direction ...
I think that if I'm right, I will not be the only one that is interested by this subject ...

Thanks a lot
Flo

I search a bit more and discover "nvgstplayer" included in the linux4tegra SDK.
It works great (seems, not tested so mush) with very low cpu usage, for divx and 480p h264 files !!!
But I have errors for 720p h264 (insufficient ressource) or mpeg1/mpeg2 (insufficient ressource too, but it's very strange because it occurs even on very low resolution video size, by opposition of h264 files that works under 480p)

Here what I did to install it (not sure all is mandatory) :
- copy from SDK "usr/lib/gstreamer-0.10" and "lib/firmware/nvmm_*" and "usr/lib/nvgstplayer"
- create some link
   ln -s /usr/lib/nvidia-tegra/libEGL.so.1 /usr/lib/libEGL.so
   ln -s /usr/lib/nvidia-tegra/libGLESv1_CM.so.1 /usr/lib/libGLESv1_CM.so
   ln -s /usr/lib/nvidia-tegra/libGLESv2.so.2 /usr/lib/libGLESv2.so
   ln -s /usr/lib/gstreamer-0.10/libgstomx.so /usr/lib/arm-linux-gnueabihf/gstreamer-0.10/
   ln -s /usr/lib/gstreamer-0.10/libgstnvxvimagesink.so /usr/lib/arm-linux-gnueabihf/gstreamer-0.10/
- install some gstreamer-0.10 packages (alsa, pulseaudio, good, bad, ugly, base ...)
And then launch nvgstplayer -i pathtovideofile

Next chapter of my quest
DivX/XVid is OK with nvgstplayer, but I want to play my mpeg2 (DVD) files !!!

VLC can read them softly with fbdev2 driver (80%CPU), but without resize and colorspace conversion.
So I recompile vlc with --enabled-egl flag.
But when I try then with opengl driver, it doesn't work with this log :

[0x40b07ac0] main gl debug: looking for opengl module: 1 candidate

I think I'm not far from the goal, if someone have an idea ...

VLC can use EGL (to use OpenGL) but does't work with OpenGL ES
