AMD has been on a streak recently of improving their open-source video acceleration capabilities for the RadeonSI Gallium3D driver.

Following the RadeonSI async VA-API and other recent RadeonSI video acceleration work, AMD's open-source Gallium3D driver for their modern GPUs has now landed multi-slice video encoding.

This RadeonSI multi-slice video encoding work is for both AVC and HEVC/H.265 formats. In turn this multi-slice encoding should yield better performance when targeting AVC and HEVC.

In addition, a deblocking filter was also merged for the AVC video encode path.

More details on the RadeonSI video acceleration support via this merge request that made it into mainline Mesa 22.3-devel on Wednesday.
