Video Toolbox
Resolved Issues
Fixed an issue and now on Apple Silicon, if width or height is greater than 4096 columns or rows and content uses 4:2:0 chroma subsampling and 8-bit depth, the hardware decoder driver will reject it and a software decoder will be automatically selected to ensure artifact-free decoding. AVC (H.264) content at level 5.2 or lower can be handled by the hardware decoder. Content that otherwise conforms to level 5.2 but is high frame rate (e.g. 4k at 100 or 120 fps) is labelled level 6, 6.1 or 6.2 and is also handled by hardware. If content is 10-bit, 4:2:2 or 4:4:4, the hardware decoder will be used. (122448862)
