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 ffmpeg version N-80801-gc0cb53c Copyright © 2000-2016 the FFmpeg developers built with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-17) configuration: --extra-cflags=-I/root/ffmpeg\_build/include –extra-ldflags=-L/root/ffmpeg\_build/lib --pkg-config-flags=–static –enable-gpl --enable-nonfree --enable-libfdk-aac --enable-libfreetype –enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx –enable-libx264 --enable-libx265 libavutil 55. 27.100 / 55. 27.100 libavcodec 57. 48.101 / 57. 48.101 libavformat 57. 40.101 / 57. 40.101 libavdevice 57. 0.102 / 57. 0.102 libavfilter 6. 46.102 / 6. 46.102 libswscale 4. 1.100 / 4. 1.100 libswresample 2. 1.100 / 2. 1.100 libpostproc 54. 0.100 / 54. 0.100 [rtsp @ 0x46594e0] SDP: v=0 o=- 45356132 1 IN IP4 192.168.5.100 s=Session streamed by stream i=1 t=0 0 a=tool:LIVE555 Streaming Media v2009.01.26 a=type:broadcast a=control:\* a=range:npt=0- a=x-qt-text-nam:Session streamed by stream a=x-qt-text-inf:1 m=video 0 RTP/AVP 96 c=IN IP4 0.0.0.0 b=AS:506 a=framerate:30.00 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1;profile-level-id=640028;sprop-parameter-sets=Z2QAKKzoB4 AiflQ=,aO48MA== a=control:track1 m=audio 0 RTP/AVP 0 c=IN IP4 0.0.0.0 b=AS:64 a=control:track2 [rtsp @ 0x46594e0] setting jitter buffer size to 0 ``` Last message repeated 1 times ``` Guessed Channel Layout for Input Stream #0.1 : mono Input #0, rtsp, from ‘rtsp://admin:admin@[ip cam address]:554/channel1’: Metadata: ``` title : Session streamed by stream comment : 1 ``` Duration: N/A, start: 0.000000, bitrate: N/A ``` Stream #0:0: Video: h264 (High), 1 reference frame, yuv420p, ``` 1920x1080 (1920x1088), 30 tbr, 90k tbn, 180k tbc ``` Stream #0:1: Audio: pcm_mulaw, 8000 Hz, 1 channels, s16, 64 kb/s ``` [flv @ 0x4696240] Using AVStream.codec to pass codec parameters to muxers is deprecated, use AVStream.codecpar instead. ``` Last message repeated 1 times ``` Output #0, flv, to ‘rtmp://[nginx server]:1935/live/test10’: Metadata: ``` title : Session streamed by stream comment : 1 encoder : Lavf57.40.101 Stream #0:0: Video: h264, 1 reference frame ([7][0][0][0] / 0x0007), ``` yuv420p, 1920x1080 (0x0), q=2-31, 30 tbr, 1k tbn, 90k tbc ``` Stream #0:1: Audio: pcm_mulaw ([8][0][0][0] / 0x0008), 8000 Hz, ``` mono, 64 kb/s Stream mapping: Stream #0:0 -\> #0:0 (copy) Stream #0:1 -\> #0:1 (copy) Press [q] to stop, [?] for help [flv @ 0x4696240] Timestamps are unset in a packet for stream 0.
