Firefox 4K HW decode on RK3588 / Orange Pi 5B BSP— VP9 green-screen fix (packaged .deb)

Some 4K VP9 videos — odd/Academy-ratio resolutions like 2970×2160 — hardware-decoded into a solid green frame on RK3588.
Root-caused to a surface-stride alignment bug in the VA-API driver and fixed. Now it's a one-line apt install, no building from source.

Quick start — BSP kernel only (/dev/mpp_service must exist):

cd /tmp
wget https://github.com/defcom5-rockchip/rockchip-vaapi/releases/download/v1.0.11-defcom5.vp9align1/rockchip-vaapi-driver_1.0.11+defcom5.vp9align1_arm64.deb
sudo apt install ./rockchip-vaapi-driver_1.0.11+defcom5.vp9align1_arm64.deb
Then wrap Firefox with LIBVA_DRIVER_NAME=rockchip + MOZ_DISABLE_RDD_SANDBOX=1, and enable media.ffmpeg.vaapi.enabled / media.hardware-video-decoding.enabled in about:config. Full steps — wrapper script, verify, YouTube tip — in the attached guide.
