ok, i see what you mean. though vp9 usually gets me 1/4 or 1/5 of h264 video so i thought it was worth to save the network traffic(even av1 got me larger file at incredibly slow speed) but as you directly pointed out, without direct support on the hardware, like h264 has these days, it will become a bottleneck so i would have to sacrifice traffic for speed and practicality and i guess vp9/av1 makes sense for youtube, bitchute or simply video HOSTING service, not for lvie streaming. thanks for lighting the bulb above my head :D
