Everything here is really niche, except video calls (and even that...).
replyIn other words, unless on smart phones, don't expect broadly distributed AV2 encoding hardware.
If it does happen on PC, it will be most likely some courtesy of the hardware chip designers.
Screen recording is not niche, anyone who works remotely probably does video calls daily and the others are somewhat more niche but I'd guess that at least 50-70% of people do at least one of these things
replyVideo calls are niche, and offline encoding of video isn't?
replyAre you sure this isn't just “things I do are commonplace, and things I don't are incredibly niche”?
