5 years ago, WebM VP9 support was promised. Now nothing. Any probability of follow through?

As seen in this thread 5 years ago: https://forum.unity.com/threads/video-player-in-5-6.459757/

Unity staff suggested WebM VP9 support would be added, yet still nothing has changed in the past 5 years.

WebM VP9 is important because it is the file format used by Blender which is probably the #1 3D rendering program most Unity users are also using with it.

WebM VP8/9 are the only ways to get good compression videos with transparent backgrounds.

If we have VP9 support, we could export such videos directly from Blender and then import them directly to Unity. However, currently that's not possible. We must export from Blender to a PNG sequence and then manually use command line tools to try to create a VP8 video that Unity can support.

I am not an expert on this. But I have read others online claiming that if Unity can already support VP8, it would be trivial to add the option for VP9. Is this not the case?

Is there any reason it still hasn't been done? Is there any chance it might be done any time soon? It would help a lot.

Thanks.

 

I'm having an issue related to this video format as well, but Unity does seem to support VP9 decoding in it's new webrtc package. https://docs.unity3d.com/Packages/com.unity.webrtc@2.4/manual/sample.html, go figure.
