I'm trying to write a standalone EVR in MF that render uncompressed YUV video received over UDP.
Is there a way to "pass" the payload to the renderer as a sample, or would I have to create a custom scheme handler? I have limited (but growing) knowledge of win32 and Media Foundation so I was hoping to just open a port using Winsock2 and parse the packets myself.
Any pointers(!) would be appreciated, this is my first adventure into Windows programming

2021-02-19T17:34:32.553+00:00 Thanks for the reply. Since posting this I have started writing my own custom media source that takes samples from a linked-link on a request sample call . I'm hoping that the EVR can use my source directly without registering the source. If you have any advice for how to do this i'd be greatful.
I'll wait to see what you may come up with in the mean time.

2021-02-26T14:02:07.503+00:00 I'm writing this project for my university dissertation and as such wanted to make it sufficiently "hard". Also my use case is fairly specific so I don't necessarily want any "gunk" that comes with working with media sessions. So implementing a standalone EVR helps keep it lightweight.
