• Android ICS FFMPEG scale video not working

  20 avril 2015, par Android-Developer

  I am using Guardian Project Android Java FFMPEG library to resize videos. Current code which is working on android 5.0.1 / 5.1.0 / 4.4.4 :

      File fileTmp = getCacheDir();
  
      FfmpegController fc = null;
  
      try {
  
          fc = new FfmpegController(this, fileTmp);
  
      } catch (IOException e) {
  
          e.printStackTrace();
  
      }
  
      String path = Environment.getExternalStorageDirectory().getPath() + "/Movies/nexus.mp4";
  
      final String outPath = Environment.getExternalStorageDirectory().getPath() + "/Movies/test.mp4";
  
      final Clip out = new Clip(path);
  
      try {
  
          if (fc != null) {
  
              fc.convert(out, outPath, new ShellUtils.ShellCallback() {
  
                  @Override
  
                  public void shellOut(String shellLine) {
  
                      Log.e("", "SHELL OUT: " + shellLine);
  
                  }
  
  
  
                  @Override
  
                  public void processComplete(int exitValue) {
  
                      Log.e("", "PROCESS COMPLETE: " + exitValue);
  
                  }
  
              });
  
          }
  
      } catch (Exception e) {
  
          e.printStackTrace();
  
      }

  Using this code on Android 4.0.4 (Ice Cream Sandwich) doesn’t do anything. While testing on other devices exitValue in processComplete is always equal to 0, but on ICS it’s 11. Here is the output in LogCat :

  SHELL OUT: /data/data/org.hardartcore.ffmpeg/app_bin/ffmpeg -y -i /mnt/sdcard/Movies/NEXUS.mp4 -ab 160k -r ntsc-film -vf scale=568:320 -strict -2 /mnt/sdcard/Movies/Test.mp4
  
  PROCESS COMPLETE: 11

  I don’t think it’s something from ffmpeg, more like a problem when the library is trying to execute ffmpeg executable from raw folder in internal memory, but I can’t see any logs or errors which indicate that too.

  So my question is, if there is any mistake which I am doing using / running this code or something which can prevent ffmpeg executable from running on old devices with Android ICS ?

  Thanks in advance !

• FFmpeg and bash, Transcode multiple files to another drive with save path

  18 juillet 2016, par Виктор Гусев

  I have folder that contain files in many different path, for example : folder1/subfolder1/file.mov
  folder1/subfolder2/file.mov

  i need to convert and copy all files to another format, and save all paths after folder 1, for example :
  folder2/subfolder1/file.mp4
  folder2/subfolder2/file.mp4

  I have this script, but it save transcoded files in original location.

  #!/bin/bash
  
  MOVIES=/Volumes/drive/
  
  find "$MOVIES" -name '*.MP4' -exec sh -c 'ffmpeg -i "$0" -map 0 -c copy "${0%%.MP4}.mov"' {} \; exit;

  Please help
  Thank you !
