RTSP Proxy: Start from keyframe

[ethaniel]

Describe the feature

Thank you for your amazing solution. I wanted to request a small feature - is it possible to keep the last keyframe of a RTSP stream in memory, so when clients connect to the proxy, they would receive this last keyframe first?

if I understand correctly, right now clients starts receiving streams from the moment they connect (which is most likely to be a non-keyframe), resulting in a weird image:

If we prepended the client's stream with a cached keyframe, the picture would be much much nicer till a proper keyframe arrives.

Just to be clear - I'm advocating for keeping a rolling storage of keyframes only (as a new keyframe arrives, the old one gets deleted from memory).
