#Iina apple silicon software

I don't have access to an Apple Silicon macOS device, so I could not test AV1 HW support. The drop in CPU utilisation with HW decoding (above) results in only a correspondingly small increase in integrated GPU utilisation (below).Īctivity Monitor: Integrated and Discrete GPU Utilisation (Second Run) IdleĬhrome requires the videotoolbox-vp9-decoding flag to be enabled. HW decoding using the integrated GPU uses less power than SW decoding using the CPU (above).Īctivity Monitor: CPU Core Utilisation (Second Run) Idle Intel Power Gadget: CPU Package, CPU Core, GPU, and DRAM Power Consumption and Utilisation (First Run) Idle If you are interested in translating this website to your language, please feel free to contact us.

I ran a brief test comparing VP9 software and hardware decoding to illustrate the significant difference. As codecs become more complex, the need for hardware decoding becomes more vital for proper playback without excessive power consumption on battery-powered devices like laptops. Playback of a high resolution, high framerate, high dynamic range video using a complex decoder = high CPU utilisation (high power consumption, hot temps, loud fans, bad performance, etc). almost all high quality YouTube videos) and their decoders are very complex. Hardware decoding of these codecs is particularly useful because they're widely used for UHD/HDR/HFR videos (e.g. IINA already supports Video Toolbox and hardware decoding. No Video Toolbox decoding of VPx/AV1 playback, always uses libmpv fallback (as of IINA 1.1.2 Build 128) Use Video Toolbox's native VPx/AV1 decoding to take advantage of hardware decoding on compatible macOS devices (more recent Intel devices for VP8/9 and only Apple Silicon devices for AV1).
