I am using OpenRTSP to open an RTSP stream (IP Camera) and send it to ffplay using Unix Pipes as input. I see the video playing which is roughly 1 to 1.5 sec delayed than live (Direct RTSP stream view of IP Cam) .
here is my command line ./OpenRTSP -v -Q -D 1 -n rtsp://<IP>:554/11 | ffplay -loglevel verbose -fflags nobuffer -i pipe:0 Now this delay slowly keeps increasing from 1.5 sec upto 4~5 seconds in about 20 minutes. And I assume it will continue to increase with time. So my questions are :- 1 - what is causing the initial delay ? 2 - Why does that delay keeps increasing ? Is there a way to disable "pre caching" of frames in OpenRTSP ? I compare the delay by watching two videos of the same IP camera. One is configured at angelcam.com and other I view locally via the above command line. Surprisingly, it is always Local stream that gets delayed. Angelcam stream keeps functioning as it started.
