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.
