New Linux Patches Enhance AMD Radeon Video Encode/Decode For Older GPUs
Since Raven/Picasso APUs and Navi GPUs there is Video Core Next (VCN) as the modern unified video encode/decode block for Radeon graphics
Open-source developer David Rosca who has been working on many improvements to the AMD Radeon video acceleration support for their Linux drivers opened a Mesa merge request to rework the VCE/UVD functionality. This newly opened merge request adds a number of features for older AMD GPUs with VCE and UVD to better match functionality that until now was only supported with the newer VCN hardware. The features being enabled for these older AMD video coding IP blocks include: VCE and UVD: - App DPB management (long term references, P hierarchy, reference invalidation, ...) - Slice encoding (128 maximum slices) - VBAQ - Quality presets (Speed, Balanced, Quality) - Min/Max QP - Max frame size - Intra refresh - Raw packed headers - Encode latency
