[RFC 0/6] VP8 H1 stateless encoding

[Hugues Fruchet]

Hi all,

Here is an RFC to support VP8 encoding using Hantro H1 hardware
of STM32MP25 SoCs (Verisilicon VC8000NanoE IP).
This work is derived from work done to support Rockchip RK3399
VPU2 in RFC [1] with a reshuffling of registers to match H1
register set.

This has been tested on STM32MP257F-EV1 evaluation board using
GStreamer userspace [2]:
gst-launch-1.0 videotestsrc num-buffers=500 ! video/x-raw,width=640,height=480 \
! v4l2slvp8enc ! queue ! matroskamux ! filesink location=test_vp8.mkv

For the sake of simplicity I have embedded here the RFC [1] before the
changes related to this exact RFC, all rebased on v6.6 + STM32MP25
hardware codecs support [3].
