Support video decoding using the VPU (using gstreamer)
Don't confuse this with #68 (closed) which only makes sure it's disabled until we can close this very issue (have support).
- Test and enhance what is being worked on upstream: https://lore.kernel.org/linux-media/?q=hantro
- Testing: most probably using gstreamer's gst-launch-1.0 (zero-copy, performance debugging, ...)
- Also important: Document what exact codecs and containers are supported in what exact levels. i.e. what video files users can throw at it.
- nice-to-have: Have good support for a free codeoc like VP9
