Hi All,

spent a significant time but not able to solve this. Any help will be highly appreciated.

Context is I am using ffmpeg to generate http streaming using below command

ffmpeg -rtsp_transport tcp -r 30 -i rtsp://root:kastle@ -c:v libx264 -video_size 640*480 -crf 35 -preset ultrafast -maxrate 500k -bufsize 500k -r 15 -g 30 -movflags +faststart -tune zerolatency -hls_time 1 -hls_list_size 4 -start_number 0 -hls_wrap 4 -hls_segment_filename S:/playlist_%RANDOM%_%1d.ts -hls_allow_cache 0 -threads 1 -loglevel warning -y S:/playlist.m3u8

it works well for upto 5 camera.

As and when I start 6th i started facing two errors:

  1. The delay in video start to increase, that is if single camera I have delay of 8 second with six it will increase more than 30 seconds. shows 32mbps speed.
  1. I started getting frequent warning of cseq once I start streaming sixth camera, like cseq 8 expected 7 received. Its continuous.

So it shows with increased number of camera there is some issue that might needs some command parameter updates? any suggestion.

Also how much maximum number of camera streaming I can support on following configuration
4cpu, 2 core, 7.5 GB Ram

Please remove the warning option and provide the command line that allows to reproduce the issue you see together with the complete, uncut console output to make this a valid ticket.
