How to combile live video streams using VideoMixingRenderer9?

I want to combine multiple live streams in single stream. So my code will take multiple streams as input & after combining it will provide single stream as output.

I have created an application which takes multiple vid开发者_Python百科eo files as input & shows them in single video.

Waiting for reply.

The only way you can get mixed output from the VMR is to implement a custom allocator/presenter. Then you will get access to the surface containing the mixed image for output.
