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@192.168.17.153
/axis-media/media.amp -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.
Sppedtest.net shows 32mbps speed.
2. 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
