RTMP Pull and hls

[mekk55]

I've just started using Nginx with rtmp module. I set up nginx.conf to "pull" from exsiting rtmp link

 application stream {
            live on;
            pull rtmp://111.222.333.444:1937/origin_appname live=1;

            hls on;
            hls_nested on;
            hls_path /mnt/hls/stream/;
            hls_fragment 3s;
            hls_playlist_length 10;
            hls_type event;

        }

Then I config for hls to alias /mnt/hls/stream/ now I can open RTMP but I'm not understand that why If I'm not open RTMP parallel with HLS there is no playlist created in /mnt/hls/stream/ it's mean that If I call only HLS Nginx will return "not found" and I checked that there is no playlist file in path.

What's mistake of configuration ?
How can I config Nginx to create playlist when call only HLS ?

Another question is I configed "secure_link" and "secure_link_md5" to HLS and now it's work for protect playlist.m3u8 but playlist didn't include secure_link after .ts so Nginx return "forbiden" for .ts inside playlist.m3u8.

How can I fix this problem ?

location /test {
        
            add_header Cache-Control no-cache;

            secure_link $arg_md5,$arg_expires;
            secure_link_md5 "$secure_link_expires$uri$remote_addr PASSWORD";

            if ($secure_link = "") { return 403; }
            if ($secure_link = "0") { return 410; }
            
            types {
            application/vnd.apple.mpegurl m3u8;
            video/mp2t ts;
            plain/text key;
            }
            alias /mnt/hls/stream/;

        }

pull is only triggered when a client is connected and playing the stream.
When there's no active rtmp client, the stream just terminated, so there no content to save to hls folder.
you can run a exec_static ffmpeg ... to pull the stream automatically

Can I wildcard exec_static ffmpeg pull like normal "pull" command ?

I had the same problem myself, which I raised in the StackOverFlow forum a little while ago. But I found the answer myself.
