Streaming videos with alpha/transparency possible?

[ValentinKraft]

Hey,

I'd like to know if it is possible to also stream semi-transparent video content in the RealtimeStreaming project for Unity on the HoloLens. On https://github.com/microsoft/MixedRealityCompanionKit/tree/master/RealtimeStreaming it says that the client uses the DXGI_FORMAT_NV12 format but it is not clear for me if transparency is supported or not.

If not - is there a way to implement/pack a transparency value inside the data/texture?

Thanks!

Point of information: NV12 does not have native support for the alpha channel (See https://wiki.videolan.org/YUV#NV12).
So my guess here is no.
