I need to do live streaming and want 2 links. one is live streaming and another is delay streaming. The delay streaming want in rtp or rtsp to put on the decoder
Unfortunately Nimble does not support streaming from DVR archive via RTMP, only HLS is supported in case of using time-shifting.
As a workaround, you can use FFmpeg to pull time-shifted HLS stream from Nimble and push it to your decoder via RTMP.
