How can I stream an flv file via http, which is currently being recorded using rtmpdump

Question

RTMP

At work, the computer is behind a proxy, which makes it almost impossible to find live sports broadcasts (almost all of them are broadcast via rtmp). Having my own VPS server, I came up with the idea to record an rtmp stream on it and then broadcast via http. The first part went well, I successfully write rtmp to an flv file, but I can’t find how to broadcast this stream now. I tried the JW player, but it determines the current length of the video and only shows up to this point, but I would like the file to be sent constantly, non-stop, taking into account the video data being added to the end of the file at that time.
PS Perhaps there is another way to convert rtmp on the go without intermediate recording of the stream to a file?
I will be glad to any ideas.

Answer 1

vlc can stream an unfinished file (I did this after rtmpdump) but takes up almost all the resources of the computer.
