Hi All,

We are having some problem regarding gstreamer Vaapi Plugin would like to discuss.

We are using gstreamer0.10.36 for our 1080p mp4 playback and we have used following gstraemer pipeline.
filesrc-> decodebin->queue->ffmpegcolorspace->xvimagesink

Here we are facing lot of buffer drop and video is displaying like slow motion so, we think that may be xvimagesink is not using the video acceleration provided by Intel, hence we moved to vaapivideosink. However we found the following error while using vaapivideosink

libva: VA-API version 0.32.0
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/dri/i965_drv_video.so
libva: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

Even the same error we are getting while doing 'vainfo' also.

We have gone through some INTERNET search, but did't find useful informations.

Basically we have 2 quires
1. Is it possible to play 1080p mp4 playback with software decoders smoothly ? How we will fix buffer drop issue ?
2. How we will use vaapi sink in other case (solving the va_openDriver() error)? Do we need to rebuild some other vaapi versions to make it work ?


Our platform information:
a. Intel-E3800 Baytrail
b. Yocto Dora build
c. Base Kernel Linux Baytrail32 3.8.0-yocto standard

Thanks in advance.

Thanks & Regards,
Meena
