dual video cards : vlc + avcodec select the "wrong" card
Config
VLC media player 3.0.12 Vetinari (revision 3.0.12-1-0-gd147bb5e)
Ubuntu 21.04 (Wayland)
Mesa 21.0.3
2 video cards
- AMD RX 5700 XT
- AMD HD6450 (very limited hardware decoding capability, not enough memory to handle 4K video)

I'd like to use the RX5700 XT for hardware decoding with VAAPI backend. (for H264, HEVC files) Test file used : https://s3.amazonaws.com/x265.org/video/BigBuckBunny_2000h264.mp4 from https://x265.com/hevc-video-files/
What happens
vlc + avcodec seems to select the wrong card ("CAICOS" = HD6450) instead of the "NAVI" ( = RX5700XT) ( /usr/lib/x86_64-linux-gnu/dri/r600_drv_video.so instead of /usr/lib/x86_64-linux-gnu/dri/radeonsi_drv_video.so ?) On screen : a black picture is displayed.
$ vlc -v BigBuckBunny_2000h264.mp4

You have to invoke vlc with LIBVA_DRIVER_NAME=radeonsi :
$ LIBVA_DRIVER_NAME=radeonsi vlc -v BigBuckBunny_2000h264.mp4

I guess it is probably safe to put this in my ~/.profile ?
