Struct I420AVideoFrame
Single video frame encoded in I420A format (triplanar YUV + alpha, 18 bits per pixel). See e.g. https://wiki.videolan.org/YUV/#I420 for details.
Namespace: Microsoft.MixedReality.WebRTC
Assembly: Microsoft.MixedReality.WebRTC.dll
Syntax
public struct I420AVideoFrame
Remarks
The use of ref struct
is an optimization to avoid heap allocation on each frame while
having a nicer-to-use container to pass a frame accross methods.
