Turn on the VAAPI ?

Hello Sir

How do we turn on the VAAPI and know the status (turn on / off) of the VAAPI? 

We do play h264 streamer(1080P FPS = 30) on  yocto + Qt5 + VAAPI + E3950 board,

The CPU usage is too high (130 %), if we play two 1080P video streams, the videos will be slowly

( FPS downgrade from 30 to 40 ) 

The  VAAPI seems to launch from below console log. 

-sh-4.4# ./customvideowidget
libva info: VA-API version 1.7.0
libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_7
libva info: va_openDriver() returns 0

 

Thanks 

Michael Wu
