Videos that are higher bit depth than 8 bit are decoded into floating point formats (so anything that uses 10/12 bits or HDR). Speedup: - Multi-thread GBRA planar -> RGBA interleaved conversion. - If video is rotated, do the rotation step while doing the above conversion directly, instead of a separate rotation afterwards. Cuts down on memory bandwidth usage. Playing back two 1920x1080 video tracks, where both are rotated and H.265 10 bit HDR, on my PC (Ryzen 5950X), average playback frame time goes 47ms -> 32ms (so 21FPS -> 31FPS) Pull Request: https://projects.blender.org/blender/blender/pulls/139439
