  • How to convert audio in each directory by FFmpeg and batch script.

    16 juin 2013, par Stallman

    After a hard study, I have created a batch file :

    for /R  D:\storytelling\MusicFiles %%a in (*.3gp) do ffmpeg -i %%a -y %%~na.mp3

    However, it can't reach my goal since the scenario is a little different here :

    Here is my directory structure :
    enter image description here

    I have several directories under a certain path :D:\storytelling\MusicFiles\ and new directories could be created by another application. And I put ffmpeg.exe file in this path : D:\storytelling\MusicFiles\.
    Also, In each directory, I have hundreds of .3gp files, and my target is to convert them to .mp3 in the directory where they used to stay at.
    But this script

    for /R  D:\storytelling\MusicFiles %%a in (*.3gp) do ffmpeg -i %%a -y %%~na.mp3

    would convert every .3gp file in each directory to the path : D:\storytelling\MusicFiles\

    It leads to :enter image description here
    But I want the publicUser_XXX.mp3 files are still in the directory publicUser and after conversion all the files remain in their original directory. The only change is that I got new a media copy with different media format like : enter image description here

    Please help and give me some advise.

  • FFMPEG Convert HTML 5 Video NOT Working

    2 juillet 2016, par Brad

    I am using FFMPEG to convert a video to .mp4, ,ogg, .webm so that it may be viewed in all HTML5 capable browsers using the video tag. The problem is that I manage to convert the video to the 3 required formats but it does not display the video in the video tag, all I get is IE9 : red cross, Firefox : Grey cross, could it be a problem with the conversion or is it something to do with the way I am adding them to the source of the video tag. Here is what I have done :

    1. FFmpeg command line(s) :

      ffmpeg -i test.mp4 test.mp4
      
ffmpeg -i test.mp4 test.ogg
      
ffmpeg -i test.mp4 test.webm

    2. Here is the video tag :

      <video height="340" width="470" preload="true" autobuffer="true" controls="true">
      
    <source src="test.ogg" type="video/ogg"></source>
      
    <source src="test.mp4" type="video/mp4"></source>
      
</video>

    3. Webconfig lines for the video support :

      <staticcontent>
      
    <mimemap fileextension=".mp4" mimetype="video/mp4"></mimemap>
      
    <mimemap fileextension=".ogg" mimetype="audio/ogg"></mimemap>
      
    <mimemap fileextension=".oga" mimetype="audio/ogg"></mimemap>
      
    <mimemap fileextension=".ogv" mimetype="video/ogg"></mimemap>
      
    <mimemap fileextension=".webm" mimetype="video/webm"></mimemap>
      
</staticcontent>

    It would be great if someone could send me the required parameters for ffmpeg to convert the video to the 3 required formats and an example of how they setting the source in the video tag to display them again. And any other advise would be great like how to set the quality up etc when doing the conversion.

    Thanks in advance.

  • Building my JAVA parameter array for FFMPEG

    29 janvier 2016, par user3541092

    FFmpeg Version : N-63893-gc69defd Copyright (c) 2000-2014 the FFmpeg developers
    built on Jul 16 2014 05:38:01 with gcc 4.6 (Debian 4.6.3-1)

    Machine : Amazon Linux t2.micro (free tier)

    Sample File : sample_iTunes.mov
    Sample File URL : https://support.apple.com/en-us/HT201549

    I’m trying to replicate the following FFmpeg command, using a string array and then pass this array into the Runtime.getRuntime().exec().

    ffmpeg -i file:/var/local/ffmpegtest/media_input/sample_iTunes.mov -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand="mp42" -b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler="Stereo" /var/local/ffmpegtest/media_output/sample_iTunes.mp4 -y

    NOTE : This works when I pass the full command, as a single string into Runtime.getRuntime().exec().

        String _cmd = "ffmpeg -i %s -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand=\"mp42\" "
    
            + "-b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler=\"Stereo\" %s -y";
    
    String _ffmpegCommand = String.format(_cmd, _inputFile, _outPutFile);
    
    p = Runtime.getRuntime().exec(_ffmpegCommand);
    
    BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
    String _line = null;
    

    
    while((_line = _reader.readLine()) != null) {
    
        lw.writeLine(_logPath + _logName, _line);
    
        System.out.println(_line);
    
    }

    I started out with just a basic parameter list. As I add add each additional parameter, I re-build the JAR file and upload it to my EC2 instance to test for any errors.

    The following string array works :

    try
    
        {
    
            String[] _params = {"ffmpeg",
    
                       "-i",
    
                       String.format("%s", _inputFile),
    
                       "-pix_fmt",
    
                       "yuv420p",
    
                       "-c:v",
    
                       "libx264",
    
                       String.format("%s", _outPutFile),
    
                       "-y"};
    

    
            p = Runtime.getRuntime().exec(_params);
    

    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    
        }
    
        catch (Exception e) {
    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    

    
        }

    However, when I continue to build the array with additional parameters, I begin to experience problems (lets add -vtag mp42) :

    try
    
        {
    
            String[] _params = {"ffmpeg",
    
                       "-i",
    
                       String.format("%s", _inputFile),
    
                       "-pix_fmt",
    
                       "yuv420p",
    
                       "-c:v",
    
                       "libx264",
    
                       "-vtag", // &lt;---- New
    
                       "mp42", // &lt;---  New
    
                       String.format("%s", _outPutFile),
    
                       "-y"};
    

    
            p = Runtime.getRuntime().exec(_params);
    

    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    
        }
    
        catch (Exception e) {
    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    

    
        }
