<HTML> Warning! Use this instruction at you own risk! You should definitly know what are you doing (especially at “Fix kernel cmdline” section) else you may get unbootable or broken system! </HTML>

Fix kernel cmdline for 3.1.10 kernel

Important! For ubuntu 12.04 you should add console=tty1 to cmdline parameters in /boot/bootimg.cfg

This line need to be changed to this state (just example, not a working config):

cmdline = mem=512M@0M tergapart=something root=UUID=anothersomething  quiet splash console=tty1

Open /boot/bootimg.cfg in you text editor and make changes.

Install latest r16 kernel image by marvin24 and nvidia-tegra drivers

First, remove previous installation if nvidia-tegra

sudo apt-get purge nvidia-tegra
sudo update-alternatives --remove arm-linux-gnueabi_egl_conf /usr/lib/nvidia-tegra/ld.so.conf
sudo update-alternatives --remove-all nvidia_drv

Then download and install new kernel and driver packages.

wget http://flie.no-ip.org:7080/ac100/deb/linux-image-3.1.10-4-ac100_3.1.10-4.5_armhf.deb
wget http://flie.no-ip.org:7080/ac100/deb/nvidia-tegra_16.1.0-0ubuntu3~fly2_armhf.deb
sudo dpkg -i linux-image-3.1.10-4-ac100_3.1.10-4.5_armhf.deb nvidia-tegra_16.1.0-0ubuntu3~fly2_armhf.deb

If you prefer you own kernel, inspect that you have CONFIG_TEGRA_AVP_KERNEL_ON_MMU=y and “CONFIG_TEGRA_NVAVP is not set” in kernel config.

Gstreamer tuninig

gstreamer-properties its a part of gnome-media package. Run

gstreamer-properties

Insert parameters nv_omx_audiosink and nvxvimagesink to its place

(Button Test prodice “could not link ffmpegcsp0 to nvxvimagesink2” error, its dont work with this driver for some reason)

Finally

sudo reboot

Done! Now you can run totem and play videos with relativly high cpu load. At this time window and fullscreen playback working in totem. Example video - h264 720p trailer Should play smoothly in totem, and you can compare it with mplayer -vo x11.

Totem keyboard shortcuts:

 F1 - Help
 F9 - Properties
 F11 - Full Screen
 q - Quit
 r - Zoom In
 t - Zoom Out
 o - Open
 p - Pause
 a - Change Format
 f - (see F11)
 h - Show/Hide Controls
 > - Frame Advance from pause (This is the one I was looking for!!)
 < - Return to pause point from frame advance
 → - Advance 1 min
 SHIFT → - Advance 15 secs
 ← - Back 15 secs
 SHIFT ← - Back 5 secs
 ↑ - Volume up
 ↓ - Volume down

Also, there is some other ways to play video inside window

nvgstplayer -i  file:///media/TOS_AC_AZ/Videos/example.avi --svs="nvxvimagesink"

gst-launch-0.10 playbin2 uri=file:///media/TOS_AC_AZ/Videos/example.avi video-sink=nvxvimagesink  audio-sink=nv_omx_audiosink

for nvgstplayer run programm from terminal and leave focus on it to have control keys.

Check permissions and owners of /dev/nv* files if any problems. It should be 0660 root:video.

OpenGLESv2

Also, you can install packages mesa-utils-extra and glmark2-es2 to watch at movings gears

es2gears

or run more complex benchmark

glmark2-es2

There is some games (even more games on russian wiki) running on ac100 via GLES2 Also check WebGL http://www.khronos.org/webgl/wiki/Demo_Repository in chromium running as

chromium-browser ----use-gl=egl
