Andrew, I ran out of time today but will test the 2 submitted vaapi patches, although I only have 1 device, just to make sure single device works as expected still (which I am sure it does, but I like to verify whatever I can).

Because I have this dual-gpu laptop with intel and radeon (r600) decoding devices I tried to get second (mesa/r600) device going but init failed .. I looked into decoding example:

and created attached patch
now you can select your specific device with env variable:
CIN_DRM_DEC=/dev/dri/renderD129 DRI_PRIME=1 LIBVA_DRIVER_NAME=r600 bin/cin
in theory same treatment can be applied (with different variable name) to second instance of av_hwdevice_ctx_create (in hw encoder init) but I have no device to test it ...
