The one thing I've always wanted from nginx-rtmp was the ability to pull from a source input instead of running a separate process with ffmpeg to push the stream over. If they could get that working my life would become less complicated quickly.

yeah I use nginx-rtmp for local video capturing (basically the functionality of a mirror) and the lag that needing to re-encode + chunk + starting off at the beginning of the chunks in the playlist introduces is meh. I think I'm going to transition my project over to WebRTC though, since the mobile device I'm using to display the video can handle that now.

  iOS still doesn't support webrtc...

    Neither does a lot of Android! Luckily the product I'm using uses https://crosswalk-project.org/ https://crosswalk-project.org/ -- that sounded like an ad!

  Currently to get the stream from ffmpeg into nginx you have to do the following: ffmpeg -re -i input_file -c copy -f flv rtmp://nginx_server_url:1935/app It would be nice to have the ability to set up an app block that looked kind of like this application source1 { exec fffmpeg -f decklink -i 'DeckLink Quad (1)@8' -f flv rtmp://localhost/app/$name } ffmpeg is still pushing the stream to nginx, but nginx is in charge of starting that process.

    I think you might be looking for the exec_pull (or exex_static) directive https://github.com/arut/nginx-rtmp-module/wiki/Directives#exec_pull https://github.com/arut/nginx-rtmp-module/wiki/Directives#ex...

      I've tried, and it doesn't work so well. I don't think it works for every OS either.

    Is there an advantage that an nginx process like that has over streaming servers like liquidsoap?
    - bcryptd 10y ago
      liquidsoap is audio only right? Most streaming servers are bloated and slow. If nginx can do for video streaming what they've done for web servers it would be great.

        Nope, liquidsoap does video. http://liquidsoap.fm/doc-svn/video.html http://liquidsoap.fm/doc-svn/video.html
