How do I pass an image to an RTMP address in Python? - sockets

Question

My goal is to stream a video to an RTMP link. I have gotten this to work by saving the video (.mp4) to a file and then using FFmpeg to stream the file to the link. However, I want to make this process faster, so I want to stream without going through the file system. My idea was to set up a client using the socket library and send the data to the RTMP server I have running via NGINX:
images = [img_as_ubyte(frame) for frame in predictions] # Contains the images that make up the video
PORT = 1935
SERVER = "localhost/live/face" # Desired RTMP Address: rtmp://localhost/live/face or rtmp://localhost:1935/live/face
ADDR = (SERVER, PORT)
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect(ADDR)
for img in images:
send = client.send(img)
I've tried putting many different things in the SERVER variable (e.g. rtmp://localhost/live/face, localhost, etc.) and I can't seem to fix the errors I've been getting (socket.gaierror: [Errno -2] Name or service not known or ConnectionRefusedError: [Errno 111] Connection refused). Does someone have any advice as to how I should pass the data to the RTMP link?
Additionally, here is my nginx.conf file:
worker_processes auto;
events {
worker_connections 768;
# multi-accept on;
}
rtmp {
server {
listen 1935;
application live {
live on;
interleave on;
hls on;
hls_path /tmp/hls;
hls_fragment 3s;
}
}
}
http {
default_type application/octet-stream;
server {
listen 4040;
#location /tv {
#root /tmp/hls/;
#}
location / {
root /tmp;
}
}
types {
application/vnd.apple.mpegurl m3u8;
video/mp2t ts;
text/html html;
}
}
