• 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,

• 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'

• How to access windows enviroment variables on MSYS ?

  15 octobre 2016, par Mostafa Sataki

  I want to build ffmpeg by vs2015 from msys2.

  In the first add vs2015\vc\bin\amd64 in to path enviroment in windows.

  Run "vs2015 x64 command prompt" as administrator then run vcvarsall.bat amd64.

  In the final go to "msys" path and then run "msys2_shell.cmd".

  I use "which cl" command for localize cl.exe.

  Output :

  which : no cl in
  (/usr/local/bin :/usr/bin :/bin :/opt/bin :/c/Windows/System32 :/c/Windows :/c/Windows/System32/Wbem :/c/Windows/System32/WindowsPowerShell/v1.0/)

  How to access to windows enviroments in the msys ?
