Question: Could we have the ability to return custom IVideoFrame objects from a video processor in the future? Alternatively, could some userdata fields be added to IVideoFrame objects? Thanks!

    Hmm returning custom implementations would be more difficult. We could add a userdata, I think, via the Extended() interface. But what is the use case of such?

    I'm writing a plugin to apply effects rendered on the GPU. Right now I'm always copying data back and forth betweens frames and GPU, but if I could detect that a frame is already on the GPU I could skip that

    hmm can you retain a copy of the frame that you return, and then return that same frame later on?

    (and when you want to purge a frame the gpu, purge it and release your associated handle?)

    Hey sorry for the late reply, lost track of this one! I don't really see how to do what you propose across different plugin instances, i.e. an instance creates a frame on the GPU then passes it on to a subsequent instance. I'm not sure how to handle that case
