  • phplondon conference 2008

    9 juin 2010, par Mikko Koppanen — Everything else, Imagick, PHP stuff, phplondon08

    To summarize it : I had fun :) My conference preparations started about two weeks before the conference. The PHPLondon fellows (Paul, Matt and Richard) asked me to do a small presentation about Imagick at the pre-conference social event. The presentation I assembled ended up being a little over two hours, give or take. The hardest part was to trim down from two hours to about 40 minutes (I didn’t want to bore the people with too many code examples). The slides are available at http://valokuva.org/talks if you need them for some reason.

    My conference day was pretty hectic from the beginning to the end. I gave a few demos about the products that we represent and the moment I opened my mouth for the first time people started leaving the room. I hope that it had something to do with the “My Framework is better than yours ?” talk starting at the same time ;)

    I met quite a lot of new people at the conference and of course it was nice to see the familiar faces from other conferences and PHPLondon meetings. I was especially happy that I was able to answer the questions Nigel James had ;)

    A huge thanks to the organizers for making this day possible !

  • 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", // <---- New
                          "mp42", // <---  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);
               }

           }

    Don't throw an error when attached picture isn't recognized.
    

    The MIME type field is required per the FLAC standard, but it's
    not an error just because ffmpeg doesn't recognize it.
