SimdYuva444pToBgraV2 #219

Closed mikeversteeg closed 1 year ago

mikeversteeg commented 2 years ago

I'm interested in SimdYuva444pToBgraV2. I currently create a reduced size of an YUV420P by first converting to YUV444P, resize it and then use SimdYuv444pToBgraV2to display. However if the original is YUVA420P, I currently don't see an efficient way to end up with reduced size BGRA.

Thanks.

Alternatively a new SimdYuva420pToBgraV2would work for me as well, I would then skip the 444 intermediate step. Either makes me happy :).

I added Base implementation of function SimdYuva444pToBgraV2. Optimizations will be soon.

Super, thanks!

Thank you for bug report. I fixed this bug.

Compiles fine now. Will let you know how it performs.
