- clouddrover 8y agoYes, but my point was don't underestimate software decoders on modern mobile devices. As an experiment, I left a local 720p30 VP9 video with Opus audio running in a loop in VLC on my iPhone 7 for 3 hours. Both video and audio are being decoded in software. My battery started at 90% and at the end of three hours it was at 55%. I think that's pretty good for software decoding. I'm not sure which VP9 decoder VLC uses on iOS. I presume it's ffvp9: https://blogs.gnome.org/rbultje/2014/02/22/the-worlds-fastest-vp9-decoder-ffvp9/ https://blogs.gnome.org/rbultje/2014/02/22/the-worlds-fastes...
