• Transcode Adobe Media Encoder live stream using FFMPEG in node.js

  23 juin 2014, par user2757842

  I am using Adobe media live encoder to send a stream up to the adobe media server. What I would like to do is take that stream and transcode it to a local file on my machine in another format other that .f4m

  Here is the code I have so far, it is built using FFmpeg within a node.js app :

  var ffmpeg = require('fluent-ffmpeg');
  
  var fs = require('fs');
  
  
  
  //make sure you set the correct path to your video file
  
  var inStream = fs.createReadStream('rtmp://localhost/livepkgr/livestream live=1'); // this is where the streams are stored
  
  var command = new ffmpeg({ source: inStream});
  
  
  
  //Set the path to where FFmpeg is installed
  
  command.setFfmpegPath("C:\\Users\\Jay\\Documents\\FFMPEG\\bin\\ffmpeg.exe");
  
  
  
  command
  
  //set the size
  
  .withSize('100%')
  
  
  
  // set fps
  
  .withFps(24)
  
  
  
  // set output format to force
  
  .toFormat('ismv')
  
  
  
  // setup event handlers
  
  .on('end', function() {
  
      console.log('file has been converted successfully');
  
  })
  
  .on('error', function(err) {
  
      console.log('an error happened: ' + err.message);
  
  })
  
  // save to file <-- the new file I want -->
  
  .saveToFile('rtmp://localhost/livepkgr/livestream1'); //this is where i want to store the newly converted stream

  I have it working with a local file but when I try it with my live stream, I get this error

  events.js:72
  
          throw er; // Unhandled 'error' event
  
                ^
  
  Error: ENOENT, open 'C:\Users\Jay\workspace\FFMPEGtest\rtmp:\localhost\livepkgr\livestream live=1'

  Anyone seen this before ?

• Windows Batch - Change the beginning of a path but keep the rest

  21 juin 2014, par o_ren

  I’m running FFMPEG for video encoding.
  I have a batch file which will encode files you drop on it, keeping the file’s original name and copy the encoded files to a specific directory.
  I would like that script to "know" the original’s file path and copy the encoded file to a path relative to it, meaning :
  original file dropped on batch file is in C :\some\folder\show\season\episode\file.mov
  encoded file should be encoded to D :\different\directory\show\season\episode\file.mp4
  The part of the path up until \show is fixed.

  This is what I have so far :
  

  @echo on
  
  
  
  set count=0
  
  for %%a in (%*) do (<br />
  
    if exist %%a (
  
  
  
          md \\specific\path\"%%~na"
  
  
  
          %MYFILES%\ffmpeg.exe -i "%%~a" -vcodec libx264 -preset medium -vprofile baseline -level 3.0 -b 500k -vf scale=640:-1 -acodec aac -strict -2 -ac 2 -ab 64k -ar 48000 "%%~na_500.mp4"
  
          copy "%%~na_500.mp4" "\\specific\path\"%%~na"\%%~na_500.mp4"
  
          copy "%%~na_500.mp4" "\\specific\path\"%%~na"\%%~na_500.mp4"
  
          del "%%~na_500.mp4"

  set /a count+=1

  ) else (
  echo Skipping non-existent %% a
  
  

  Thank you,
