• ffmpeg - caching ahead piped input as insurance while maintaining low latency and real-time output

  5 décembre 2020, par hedgehog90

  I'm piping a live transcoded stream into ffmpeg (simplified for brevity) :

  


  mpv playlist --o=- | ffmpeg -re -i - -tune zerolatency -f flv rtmp://blah.com/live

  


  The piped input usually runs above 1x encoding speed, but every now and then it can run a little slower than real-time (just a momentary 0.99x or 0.98x dip).
When this happens, the rtmp server (a popular streaming service with an audience) output will pause momentarily for a couple seconds usually.

  


  To overcome this I want ffmpeg to cache a few seconds in advance, so mpv's output (which outputs at whatever speed it's read, so potentially very fast) can supply ffmpeg with a little extra, and whenever mpv goes a little under 1x speed, there's a little insurance that ffmpeg has cached away. This should be doable while maintaining the lowest possible latency.

  


  Question is, how ?

  


• Best and latest live video streaming soloution [on hold]

  3 avril 2015, par Ford

  I have read a few old posts on StackOverflow about live video streamins, but as they are from around 2008, i assume things have moved on from then... and wonder if a current thread will be useful to me and others.
  Also looking on google gives lots of stuff, but again i dont know who is best to listen to and who is trying to sell their stuff (not that i am against paying).

  Basically what are the main points i need to know in order to add/develope a feature to a website in order to offer "1 on 1" and "1 to many" MULTIPLE live streaming webcam, with voice and text chat.

  I am quiet competent with PHP, OK with basic JavaScript (of course fine with HTMLL/css), but do not know what code i would need for client side software, or if any "off the shelf" software is suitable.
  I have played with ffmpeg and noticed this offers streaming, but i dont know if it would be suitable or the best available option.?
  I have a dedicated server with virtualization so can add a dedicated box for streaming if needed/better.

  Any info that can point me off in the right direction of how to add a live streaming service to a website would be much appreciated !
