Merged this week to FFmpeg Git for this widely-used open-source multimedia library are a number of NVIDIA video encoding "NVENC" improvements for benefiting the new GeForce RTX 50 "Blackwell" graphics processors.

Among the FFmpeg changes merged are [1]4:2:2 HEVC/H.264 encoding and H.264 10-bit encoding for Blackwell GPUs. Plus similar changes on the [2]video decoding side. There is also now [3]UHQ for AV1 encoding to support Ultra High Quality AV1 video encoding. Plus [4]Temporal Filtering for AV1 and H.264 to yield video coding efficiency improvements by 4~5%.

Lastly there are also some changes around [5]NVIDIA Video Codec SDK 13.0 support.

Great seeing NVIDIA working on getting these Blackwell NVENC/NVDEC improvements merged into FFmpeg in a timely manner for benefiting video acceleration on the new [6]GeForce RTX 50 graphics cards.
