  I run the funtion indianull and expected it to convert a video , in my desired format + add logo + add subtitles ! Takes the original Video from on folder , Subtitles from another folder , and converts the video , and saves it in another folder ..

  


  the issue i see only is :
"\[af#0:1 @ 0x600001ad9cb0\] Error sending frames to consumers: No space left on device \[af#0:1 @ 0x600001ad9cb0\] Task finished with error code: -28 (No space left on device) \[af#0:1 @ 0x600001ad9cb0\] Terminating thread with return code -28 (No space left on device) \[out#0/mp4 @ 0x600001dd8540\] video:0KiB audio:0KiB subtitle:0KiB other streams:0KiB global headers:0KiB muxing overhead: unknown"

  


  I do defenitly have over 400GB free on My SSD !
Is an an speciffic folder that is full ? and can not hold any files ?

  


  Any idea how to solve this ? or any suggestion how to try to solve ?

  FFmpeg Successfully Pushes Stream to Nginx RTMP but Unable to Play with ffplay or VLC

  


  I followed the tutorial below :tutorial

  


  to set up an RTMP server using Nginx, and successfully pushed a stream with FFmpeg.
Here is the nginx.conf file :

  


  rtmp {
        server {
                listen 1935;
                chunk_size 4096;
                allow publish 127.0.0.1;
                deny publish all;

                application live {
                        live on;
                        record off;
                        allow play all;
                }
        }
}


  


  and here is the console output from pushing the stream :

  But when I try to play the stream using ffplay or VLC, it gets stuck in a waiting state.

• Live streaming multiple bitrates with FFmpeg and node.js

  14 juillet 2014, par user2757842

  I am looking for an efficient way of transcoding a live stream and breaking it up into different bit rates, I have it working as of now but I have to state each time which video I would like to address as well as each different bit rate, example below :

  var spawn = require('child_process').spawn;
  
  
  
  /*
  
  var ffmpeg = spawn('C:\\Users\\Jay\\Documents\\FFMPEG\\bin\\ffmpeg.exe', [
  
      '-i',
  
      'rtmp://192.168.201.8/livepkgr/livestream2 live=1',
  
      '-movflags',
  
      'isml+frag_keyframe',
  
      '-f',
  
      'ismv',
  
      'http://192.168.201.237/LiveSmoothStreaming.isml/Streams(video2)'
  
  ]);
  
  */
  
  
  
  var ffmpeg = spawn('C:\\Users\\Jay\\Documents\\FFMPEG\\bin\\ffmpeg.exe', [
  
      '-i',
  
      'rtmp://192.168.201.8/livepkgr/livestream live=1',
  
      '-ac',
  
      '2',
  
      '-b:a',
  
      '64k',
  
      '-c:v',
  
      'libx264',
  
      '-b:v:0',
  
      '150k' /* first bit rate i want */ ,
  
      '-movflags',
  
      'isml+frag_keyframe',
  
      '-f',
  
      'ismv',
  
      'http://192.168.201.237/LiveSmoothStreaming2.isml/Streams(video1)',
  
      '-c:v',
  
      'libx264',
  
      '-b:v:0',
  
      '500k' /* second bit rate i want */ ,
  
      '-movflags',
  
      'isml+frag_keyframe',
  
      '-f',
  
      'ismv',
  
      'http://192.168.201.237/LiveSmoothStreaming2.isml/Streams(video3)'
  
  ]);

  As you can see, this is not a very efficient way of doing it as this is only for 2 bit rates, I have to give a video name (video1, video 3 etc) each time I want a new bit rate and then I have to give it it’s bit rate (150k, 500k etc). If I wanted anymore bitrates, the code lines would go on and on and it would quickly become messy.

  Has anyone worked within the world of Node.js and FFmpeg that could maybe point me in the direction of managing this more efficiently ? Or even link me to a page which would help me out ?

  Cheers
