I would like to build a h.264 video player that uses as little laptop energy as possible.
I have a program that has about 50% worse CPU usage than QuickTime, and I'd to make it better.
Can you fix my issue?
What would you use Metal for? Color management?
H.264 decoding is not something a GPU can do easily. The good news is that almost every Mac includes a ASIC H.264 decoder, you can use it with the Video Toolbox API.
