Mesa 24.3 Radeon VCN Adds HDR Metadata Support For AV1 Encoder

([Radeon] 5 Hours Ago RadeonSI VCN)


The latest video acceleration improvements to report on with the open-source AMD Radeon driver front is support in Mesa 24.3-devel for passing HDR metadata in the AV1 encoder.

This newly-merged code to Mesa Git allows passing High Dynamic Range (HDR) metadata from the Video Acceleration (VA) front-ends onto the Video Core Next (VCN) AV1 encoder with the AMD graphics hardware.

AMD engineer Ruijing Dong explained in [1]the merge request :

"radeonsi/vcn: add support of HDR meta data in AV1 encoder

Add HDR meta data support in AV1 encoder, when the source contains MDCV (mastering display color volume) or CLL (content light level), when doing transcoding/encoding, these HDR MDCV and CLL information can be transferred to av1 bitstream as meta data."

This improvement for AMD AV1 encoding/transcoding of HDR content is now in Mesa Git for next quarter's v24.3 release.

phoronix

Leslie West heads for the sticks, to Providence, Rhode Island and
tries to hide behind a beard. No good. There are still too many people
and too many stares, always taunting, always smirking. He moves to the
outskirts of town. He finds a place to live -- huge mansion, dirt cheap,
caretaker included. He plugs in his guitar and plays as loud as he wants,
day and night, and there's no one to laugh or boo or even look bored.
Nobody's cut the grass in months. What's happened to that caretaker?
What neighborhood people there are start to talk, and what kids there are
start to get curious. A 13 year-old blond with an angelic face misses supper.
Before the summer's end, four more teenagers have disappeared. The senior
class president, Barnard-bound come autumn, tells Mom she's going out to a
movie one night and stays out. The town's up in arms, but just before the
police take action, the kids turn up. They've found a purpose. They go
home for their stuff and tell the folks not to worry but they'll be going
now. They're in a band.
