Fallbacksrc impose delay of 2 seconds to input stream

General Discussion

i tried to use fallbacksrc/sink for managing rtsp stream - when stream fails/disappears - it switching to backup image/stream .
looks like everything works, but it is a huge delay between input to fallbacksrc and output time of stream fro mfallbacksrc -it constant 2seconds. where/how to get rid of such delay and rung stream with minimal latency?

2s sounds like the default latency on rtspsrc. You can reduce that via the latency property.

OOC, does your sink have sync=false?
