gstreamer-vaapi no plugins

[Suniel Mahesh]

Hi all,

I am trying to test video encoding on rockchip PX30 SOC,
using gstreamer-vaapi plugins.

Rockchip PX30 is a rockchip RK3326 variant which has ARM
Quad-Core Cortex-A35 and Mali-G31 GPU.

I have integrated gstreamer-vaapi onto yocto build and using export
GST_VAAPI_ALL_DRIVERS=1

gst-inspect-1.0 vaapi complains:
WARN vaapi gstvaapiutils.c:78:gst_vaapi_warning:
vaGetDriverNameByIndex() failed with unknown libva error, driver_name
= (null)

vainfo:
libva info: VA-API version 1.10.0
libva error: vaGetDriverNameByIndex() failed with unknown libva error,
driver_name = (null) vaInitialize failed with error code -1 (unknown
libva error),exit

I dont see any vaapi plugins, especially:
 vaapih264dec vaapih265dec vaapih264enc vaapih265enc

However, I am using VAAPI user space implementation libva-v4l2-request
from bootlin.
https://github.com/bootlin/libva-v4l2-request

with this, it shows few plugins, but it is not convincing:
vaapidecodebin
vaapipostproc
vaapisink

Any inputs/suggestions. Thanks

Regards
