5.0 Play Video and Check CPU Utilization
1. Ensure that MPlayer is built with vaapi enabled:
mplayer -vo help
vaapi should be among the list of video output drivers listed by the above
command.
2. Play the video with MPlayer using hardware acceleration:
mplayer -vo vaapi -va vaapi -ao alsa <example_video_clip>.mp4
3. To check CPU utilization, open another terminal and enter:
top
Max CPU utilization for the MPlayer application should be about 10% (with 1080p
videos).
6.0 Run Glxgears and Check CPU Utilization
1. To check whether graphics hardware acceleration is enabled, enter the following
commands:
glxinfo | grep renderer
The string
OpenGL renderer string: PowerVR SGX545 should appear in the
output, indicating that the PVR-CDV OpenGL driver has been correctly installed.
glxinfo|grep direct
In the output, look for the string
direct rendering: Yes, which indicates that
graphics hardware acceleration is enabled.
2. Launch the glxgears demo:
glxgears -fullscreen
A full screen animation of three rotating gears starts to play.
Press the Esc key to stop glxgears.
3. Launch the
glxgears demo (non-full screen):
glxgears
The glxgears animation starts in a new window.
4. To check that CPU utilization, open another terminal and enter:
top
Maximum CPU utilization for the glxgears application should be less than 2%.
