Thank you, that is probably what I was missing as I do not frequently deal with the Apple ecosystem. On the note of YouTube, my understanding is that they gracefully fall back on H.264 if you lack support for VP9 on your hardware (they probably are or will do the same for AV1). Google is most likely promoting VP9 this way for their own long-term benefit. HLS has also been an issue as the RFC mandates proprietary codecs, but Apple have silently added VP9 support recently in their implementation [1]. The HLS container formats are still proprietary though from what I can understand. MPEG-DASH should support VP9 and AV1, but I have not read up on it much as MPEG-DASH is proprietary as a protocol [2].
