  • ffmpeg command failed

    25 octobre 2015, par Asad kamran

    I am experimenting FFMPEG command to convert any video format to mp4.

    Server admin execute the below command created by me and show me the errors :

    ffmpeg -ss 00:03:00  -i  /video/1444107854.mov -c:v libx264 /video/player/1444107854.mp4  -vframes 1 /video/thumb/1444107854.jpg

    This is error :

    [aac @ 0x2b845a0] The encoder ’aac’ is experimental but experimental
    codecs are not enabled, add ’-strict -2’ if you want to use it.

    how can i avoid this error and also experimental codec, so can any one let me know what can be best codec if i explicitly specify it.

    my ffmpeg and server are as follow :

    ffmpeg version N-75903-g14573b9 Copyright (c) 2000-2015 the FFmpeg
    developers built with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-16)

    EDIT 1 :
    I change the command a bit and add -c:a copy to copy audio stream as it is but still no hope :

    New command :

    ffmpeg -ss 00:03:00  -i  /video/1444107854.mov -c:v libx264 -c:a copy /video/player/1444107854.mp4  -vframes 1 /video/thumb/1444107854.jpg

    After executing this i got a file of 23k size, apparently as in log it only copy audio stream and no video is added in final output.
    Its Log is as follow :

  • 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),
