The policy on how a media input should process the frame.
ProcessFramePolicy affects how media packets move from one processing element to the next in a media track. The default behaviour is synchronous, which is recommended for almost all applications. There are a few niche use cases (generally server-side) where a media track includes a branch with hundreds or thousands of leaves, in which case processing asynchronously (with accompanying thread-pool tuning) can eliminate the effects of favoritism in processing time towards the first leaves.
