Till now, I only tried to stream a local mp4 media file to nginx rtmp
server and replay the stream simultaneously. The steps are shown
below:
1. Start the self-compiled nginx rtmp server with the following
settings appended at the end of the default
/usr/local/nginx/conf/nginx.conf:
rtmp {
server {
listen 1935;
application live {
live on;
}
}
}
2. Publishing a Stream via FFMPEG:
$ ffmpeg -re -i in.mp4 -c copy -f flv "rtmp://127.0.0.1:1935/live"
3. Pull the steam with vlc:
Fill out the following URL in "vlc --> Media --> Open Network Stream"
and click on the play button:
rtmp://127.0.0.1:1935/live
> What will be the use?
Currently, I'm participating in a remote driverless car monitoring
system, which utilize the camera installed on the car to capture the
real-time state of the surrounding environment and transfer it to the
monitoring device located remotely. The platform installed on the car
is an embedded Linux distribution, say, Raspberry Pi.
I plan to do this with the following ideas: ffmpeg is used to capture
the camera device and then rtmp(s)/hls protocols are used to publish
the stream to the rtmp(s)/hls server supplied by nginx running on a
cloud based VPS. On the remote client/monitoring side, we can access
the nginx server by a rtmp(s)/hls capable client software/browser,
e.g. VLC/Firefox/Chrome for real time monitoring.

I think it should do the both simultaneously.

See the detailed description of the above-mentioned project background.

Wonderful notes and valuable experiences. Thanks a lot for sharing it
with me. But I still have a question on your notes, to be more
specific, I think for the rtmps/hls protocols, the stream URLs should
look like "rtmp://" and "hls://". But I don't know how to setup these
type of nginx based streaming servers. Furthermore, I also learned
that rtmps ptotocol is not supported by nginx rtmp module currently as
told by the notes give by
<https://dev.to/lax/rtmps-relay-with-stunnel-12d3>:
Unfortunately nginx-rtmp-module doesn't support replaying to an
rtmps:// address, and the feature is not supposed be added in a recent
release.
There's an issue nginx-rtmp-module#1397 discussing about this.

Thanks again for your hard work and due diligence. I will make further
attempts according to your notes and give the necessary feedback.
Best regards
