But then you need to copy the memory from the decoder to the video output or you get back to the same problem to work-on.



No, you can use a shared memory segment for a buffer just for that.

It's more coding, certainly, but it's possible. Security is an option if we wanted it.


That's exactly the point above. See my above comment.


I'm not sure, it sounds like you're saying we'd need to copy memory.

The shared memory segment can be a GPU image buffer, so I don't think that's true.


See comment above with "the solution".

Either you need to have multi-process and correct IPC, or you need to copy.
