    Calling all video codec experts. What determines whether a video is decoded in the hardware(GPU) or software(CPU)?

    Does this have anything to do with the actual codec (HAP, etc) used?
    Or is it the application that loads the video and performs the playback?
    I'm trying to optimize 4K video playback and I see that CPU usage is often at 70% or more.
