WebM v1 aka VP8/Vorbis WebM v2 aka VP9/Opus in the future it will probably look like this WebM v3 aka AV1/Opus the preferred container for av1 is webm as the encoder and decoders has a muxer and demuxer built in already you can still put it in matroska, mov, and other containers, but webm has a much better compatibility guaranteed than other containers, its much closer to mp4 which only has AVC/HEVC with AAC audio etc

As regards the codec HEVC. In the Magix Vegas 14 codec Intel HEVC is in MOV container. PS Even half a year ago it was added to the VPX codec MOV. Now is blocked and the problem solved. Sam codec AV1 IVF currently can't be added to the Matroska container. Quote:
VP9 in MP4 support is experimental, add '-strict -2' if you want to use it. That may change in a month. ffmpeg.exe -i input.mov -f mp4 -c:v libvpx-vp9 -vb 2000k -strict -2 output.mp4 At one time the user RBO wrote two articles about the construction of codecs in containers VP9 / AV1. Unfortunately I don't received information, will codecs vpx be implemented in MP4Box? Last edited by Jamaika; 24th January 2017 at 16:20. |

In the press from the previous year was just a suggestion:
While this collaboration falls far short of Apple joining the Alliance for Open Media, it does signal that the two companies can work together effectively. It also indicates that Apple, long and publicly intransigent on MPEG DASH, is willing to contribute to new standards that benefit the common good. Will Apple join the Alliance? “We’ve been talking to a lot of companies, and recruiting definitely isn’t our challenge," Gabe Frost said. "The hard part is the engineering effort, taking the next step, and driving contributions through the open source project.” |

Google has stopped encoding 4k videos in h264, leaving Safari users on Mac OS without that option. VP9 is still impacting battery life though so my guess is Apple will start shipping AV1 decoders once bitstream is frozen. Implementing VP9 now would be a bit pointless and Apple has been sticking with h264/AAC for a rather long time, hence they will most likely want the same ROI on the next set of codecs.
Joining the AOM now might just completely break down support for HEVC as well since Apple is one of the final large holdouts not shipping consumer devices with VP9. Not sure if Apple wants to do that or if they are bound by agreements with the MPEG LA not to relicense their patents to others. At this stage they are probably just waiting for AV1 to be complete and then making a decision. |

An overview of AOM from last year. Mostly old news and a recap, though in response to a question they do mention that AV1 is not the final name for the codec. Also justifies some of Youtube/Google's design decisions around sending video to people in countries where the CPU available is higher than the bandwith. |

And it is hasn't pass IP test, I can bet the bitstream wont be frozen until next year. It is good they didn't rush it. But another year for HEVC to gain. Let's just hope Apple hold off HEVC for another year. |

No-one is adopting h265. Only broadcast and ultra hd bluray are using it. Almost no digital cameras record in h265 even though there have been hardware encoders for years for mobile devices. AV1 shall be the king for many years on the web. We really could do with safari adding support for vp9 though in the meantime.
