Can't force broadcast stream from the camera?

Question

Nginx

Settings in nginx.conf
rtmp {
access_log /var/log/nginx/rtmp_access.log;
server {
listen 1935;
ping 30s;
notify_method get;
application ii {
live on;
exec_pull ffmpeg -i rtsp://192.168.111.120:554/Streaming/Channels/1 -threads 2 -f flv -r 25 -s 1920x1080 -an rtmp://localhost:1935/ii/stream;
}
}
}
what could be the problem, I run it in the terminal:
[email protected]:/etc/nginx# ffmpeg -i rtsp://192.168.111.120:554/Streaming/Channels/2 -c copy -f flv rtmp: //localhost:1935/ii/stream

Answer 1

Why didn't you specify the video codec parameters?
add to ffmpeg
ffmpeg -i rtsp://192.168.111.120:554/Streaming/Channels/1 -threads 2 -vcodec copy -r 25 -s 1920x1080 -an -f flv rtmp://localhost:1935/ii/stream;
