Date: Sun, 10 Dec 2023 15:38:15 +0100
Message-ID: <DU0P250MB07475EFBDCBDED1440E73A9E8F88A@DU0P250MB0747.EURP250.PROD.OUTLOOK.COM> (raw)

Nuo Mi:
> vvc decoder plug-in to avcodec.
> split frames into slices/tiles and send them to vvc_thread for further decoding
> reorder and wait for the frame decoding to be done and output the frame
>
> Features:
> + Support I, P, B frames
> + Support 8/10/12 bits, chroma 400, 420, 422, and 444 and range extension
> + Support VVC new tools like MIP, CCLM, AFFINE, GPM, DMVR, PROF, BDOF, LMCS, ALF
> + 295 conformace clips passed
> - Not support RPR, IBC, PALETTE, and other minor features yet
