Help with gstreamer-vaapi + rockchip vpu vaapi driver

[Ezequiel Garcia]

Hi guys,

I'm trying to get gstreamer-vaapi to work with the VPU codec driver
I'm working (for Rockchip platforms).
However, despite having a seemingly working vaapi driver:

# vainfo
error: can't connect to X server!
libva info: VA-API version 1.2.0
libva info: va_getDriverName() returns -1
libva info: User requested driver 'v4l2_request'
libva info: Trying to open /usr/lib/va/v4l2_request_drv_video.so
libva info: Found init function __vaDriverInit_1_2
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.2 (libva 2.2.0)
vainfo: Driver version: v4l2-request
vainfo: Supported profile and entrypoints

v4l2-request: Unable to set MG2S format for type 10: Invalid argument
      VAProfileH264Main               :    VAEntrypointVLD
      VAProfileH264High               :    VAEntrypointVLD
      VAProfileH264ConstrainedBaseline:    VAEntrypointVLD
      VAProfileH264MultiviewHigh      :    VAEntrypointVLD
      VAProfileH264StereoHigh         :    VAEntrypointVLD

Gstreamer-vaapi don't output any elements:
