Phoronix: Big Video Encoding Rework Lands For AMD Open-Source Mesa 24.3 Driver

A set of a dozen patches have reworked the video encode handling within Mesa 24.3 for the Video Acceleration (VA) front-end and the RadeonSI/VCN driver code. This rework aims to enable new features moving forward, enhance the overall driver, and bring "significant" memory savings for H.265/HEVC video encoding...

The biggest problem with AMD's hardware encoding is not the drivers, it's the hardware.

Even on Windows where the drivers are mature and hardware encoding is well supported via rigaya VCEEnc, the quality of the encoded file is significantly lower than that produced by Intel and NVIDIA hardware encoders.

AMD did buy Xilinx, which had an excellent hardware encoding solution and AMD does offer hardware encoding solutions based on that IP that are supposedly excellent, they are not including the same hardware in their consumer products, which is understandable,

If you want hardware encoding in the consumer space, you forget about AMD and go with either NVIDIA or Intel.

With av1 I don't think there is any problem with encoding on Linux on Radeon cards

Are there recently video quality comparisons across various hardware encoders in low end CPUs?

I'm interested in seeing comparisons for real-time 1080p H264 and HEVC encoding for N100, Rockchip SoCs, AMD's etc.

Many of the recent tests I've found have been high-end GPUs only.

It only seems understandable if nvidia didn’t have such a superior product. Using Xilinx solutions on-board would allow a catch-up to four.
