Re: [Live-devel] OpenRTSP stream delay increasing with time

No. Our code delivers data (in this case, to the OS pipe, and from there to your "ffplay" command) once it arrives. The 'increasing delay' that you're seeing has to be caused by your downstream code (your "ffplay" command) not consuming data fast enough. Either your "ffplay" command is CPU bo

[Live-devel] OpenRTSP stream delay increasing with time

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://:554/11 | ffplay -loglevel
