ffmpeg restreaming to nginx, connection refused

Question

New to ffmpeg and read a dozen of guides and howto, but still can't get it to work.

I have a Tvheadend server that receives channels from DVB, the channels work without any problem, but I need to transcode it so that U can see the channel outside my home.

I tried installing nginx+rtmp module with ffmpeg on a more powerful server (ubuntu 18.08), but whatever I do I can't seem to get it to work.

Here's what I'm trying:

ffmpeg -f mpegts -i http://username:[email protected]:4445/stream/channelid/9 -deinterlace -vcodec libx264 -vb 1000k -acodec libfacc -ar 48000 -ab 48k -f flv rtmp://192.168.0.58:1935/test

The source is a tvheadend server and the rtmp server is the ffmpeg where the transcoding is going to be done.

"Unknown encoder 'libfacc'" — start with that issue. Use -acodec aac instead. — slhck, Commented Jul 17, 2018 at 8:22

the aac syntax did work, but now i get a connection refused error — hans gerte, Commented Jul 17, 2018 at 10:24
Well, do you have a server running on 192.168.0.58 and listening on TCP port 1935? If not, you have to configure and start the server appropriately. — slhck, Commented Jul 17, 2018 at 10:52

The OP solved the problem by re-installing the nginx-rtmp module, making sure that the RTMP port was open using netstat -altun. He also made sure that the string of ffmpeg was the same as the nignx server.
