Low udp-buffer-size results in out-of-order frames at sink

logidelic
I have been using rtspsrc pipelines for about two years now, on various platforms, with various GStreamer versions, and have consistently observed something that I can't understand:

If the udp-buffer-size is too low, there can be artifacts & corruption in the resulting video. This by itself can make sense. However, what we also see is that some frames that make it to the sink are out of order: For example we may see a flash of a person in the room, even if that person was already observed having left the frame in the previous several sink buffers.

How can this happen? Is it an error in the packet-drop logic or is there something I'm missing?

Thank you!

- Bill
