Server:

Linux CentOS 6.(x)

NGINX with RTMP module enabled (compiled myself using an online tutorial)



I use FFmpeg to stream to this server, and one stream works perfectly.


Example of perfectly working stream from IP camera:



ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test1



and to pull the stream, I use VLC/FFplay, and rtmp url is like so:



ffplay rtmp://[nginx server]:1935/live/test1



Problem comes when I try to stream two streams simultaneously, like so:



ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test1

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test2



in this case, both streams is mostly choppy, and sometimes one stream fails
to load at all.



If I extend this to 10 inputs like so:

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test1

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test2

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test3

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test4

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test5

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test6

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test7

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test8

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test9

ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test10



Then although I can see all console are streaming perfectly fine, like so:



ffmpeg -loglevel verbose -rtsp_transport tcp -i rtsp://admin:admin@[ip cam
address]:554/channel1 -c copy -f flv rtmp://[nginx server]:1935/live/test10

Can anyone tell why multiple RTMP streams are not being entertained? Is
there any streaming restriction on nginx I am unaware of?
