The alliance is forming and AV1 is comming. Would be nice if vMix would support it in the future.

Knowing the guys at vMix and what they have done with developments like NDI then I think it goes without saying that AV1 once established as an acceptable format will be in a version of vMix before you can say “AV1 is now available in vMix”!

Bringing this back to top of thread now that ADA Generation NVIDIA GPU's have AV1 hardware encocders onboard, and more and more streaming sites are starting to impliment AV1 ingests.

We're keeping an eye on things in regards to AV1 for streaming, but unfortunately there are still some technical hurdles behind the scenes that need to come together
before it will work.
The first is no major streaming provider supports AV1 for ingest just yet.
There has been a lot of talk out there of support in the industry, but the truth is actual implementations outside of lab demos have yet to be seen.
The second is the Transport Stream format for AV1 is still not supported in most of the tools used to encode it, especially FFMPEG.
This piece of the puzzle is necessary to create HLS streams on the fly for example.
We hope to be one of the first to implement AV1 streaming support as soon as the above hurdles have been solved.

Martin

Just Youtube are opening up RTMP+ / enhanced RTMP for support of more codecs, including AV1. (should be lower latency than HLS). Also FFmpeg 6 now has support for nvenc AV1 and QSV AV1. AV1 streaming to YouTube over RTMP is currently in beta in OBS - though I believe they use a custom RTMP integration rather than using FFmpeg's, and I can't see that FFmpeg supports the enhanced RTMP spec yet. As an aside, OBS monitors the RTMP connection and lowers the bitrate if the buffer starts to grow, it would be great if vMix could do similar. As a further aside, YouTube have also joined the SRT Alliance. vMix streaming AV1 over SRT to YouTube with dynamic bitrate control would be my ideal solution (well, with some sort of connection bonding it would be even better) - in case you haven't guessed I stream a lot for semi-remote locations with poor connectivity!

Well after talking to support, IMO I would not expect this anytime soon. Sucks. I just went out and bought 4 4090's for this based on the post they made saying "We hope to be one of the first to implement AV1 streaming support as soon as the above hurdles have been solved.". Does not look like they will be.

vMix This could be useful for linking SRT streams between Vmix machines for the best quaility.

We are still waiting for the full support necessary from the FFMPEG encoder in order to do AV1 streaming.
As soon as they do release full support, we will looking to add AV1 support to vMix also.

Not sure who all missed the last live show like I did, but AV1 will be coming in version 27 and in the beta version when its available.
