VA-API would be difficult anyway as it is tied to Linux DRM. My question remains
though: why isn't this implemented with the NVDEC API? FFmpeg already support
NVDEC natively with the same set of codecs as this patchset, and presumably
with all the necessary codec state tracking.
This would also address Timo's concerns by moving the driver into a library,
and shield FFmpeg from hypothetical L4T ABI breaks.
