When video decoding happens in RDD process, RenderTextureHostWrapper wraps actual RenderTextureHost. And if the RenderTextureHost does not support RenderTextureHostSWGL, RenderTextureHostWrapper::GetPlaneCount() returns 0.

And RenderDMABUFTextureHost, RenderEGLImageTextureHost seemed not support RenderTextureHostSWGL.

Then RenderDMABUFTextureHost might be related.

But I do not know well about RenderTextureHostSWGL.

:lsalzman, is there a such possibility?
