Supporting Hardware Codecs in a Linux system

on YouTube ↗35m

" summary

Mainline Linux gains a working path to Allwinner hardware codecs: a reverse‑engineered Allwinner Cedar stack plus a v4l2 driver in staging (mpeg‑2 merged in 4.20) and a funded effort that adds h.264 and h.265 support via a v4l2 request API now merged for newer kernels. Userspace integrates through libva/VDPAU shims to feed slices to Kodi/GStreamer/VLC, but tiling formats, X11 compositor limits and Mali driver gaps make display and scaling slow or awkward unless KMS/DRM stages the buffers directly.
