FFmpeg Adds H.265 Tile Encoding Support For VA-API With Intel Icelake+
Tile encoding is now exposed for FFmpeg's H.265 VA-API encode path. The number of tiles can be configured by the user but a best effort will be made to use a sane default for the number of tile rows and columns in splitting up the video encode workload. With tile encoding the aim is to offer greater parallelism/efficiency of the process.
The HEVC VA-API tile encode support was merged today into FFmpeg Git. As part of that effort was also introducing the infrastructure for tile slice encoding in VA-API.
