[SUGGESTION] Can AVX/AVX2/AVX-512 optimizations speed up encoding ? #175

Closed MarcoRavich closed 1 year ago

rigaya commented 1 year ago

Already AVX2 is used on colorspace conversion, and AVX2/AVX512 for bitstream parsing.

AVX2/AVX512 will not help for encoding tasks on the GPU side (as it is a CPU feature).

Sorry, the message body hasn't been posted, here it is:

Many a/v de/en-coders are introducing (even compiler-only) AVX* optimizations, here's a couple of examples:

Anyway thanks for the tech explaination.
