Android FFMPEG java concat multiple files
17 juillet 2015, par Kim TI’m using a fork of the cordova-plugin-video-editor library :
https://github.com/jbavari/cordova-plugin-video-editor/pull/13
Which uses the android-ffmpeg-java library here :
https://github.com/guardianproject/android-ffmpeg-java
The out of box cordova plugin example works well to encode a single video using the following code :
File tempFile = File.createTempFile("ffmpeg", null, appContext.getCacheDir());
FfmpegController ffmpegController = new FfmpegController(appContext, tempFile);
TranscodeCallback tcCallback = new TranscodeCallback();
Clip clipIn = new Clip(videoSrcPath);
Clip clipOut = new Clip(outputFilePath);
clipOut.videoCodec = "libx264";
clipOut.videoFps = "24"; // tailor this to your needs
clipOut.videoBitrate = 512; // 512 kbps - tailor this to your needs
clipOut.audioChannels = 1;
clipOut.width = outputWidth;
clipOut.height = outputHeight;
clipOut.duration = videoDuration;
ffmpegController.processVideo(clipIn, clipOut, true, tcCallback);This calls the android-ffmpeg-java code here :
They have a multiple file concat test example here :
So I have modified the cordova plugin code to match the example :
ArrayList<clip> listVideos = new ArrayList<clip>();
Clip clip = new Clip();
clip.path = new File(videoSrcPath).getCanonicalPath();
ffmpegController.getInfo(clip);
clip.duration = 5;
listVideos.add(clip);
Clip clip2 = new Clip();
clip2.path = new File(videoSrcPath2).getCanonicalPath();
ffmpegController.getInfo(clip2);
clip2.duration = 5;
listVideos.add(clip2);
Clip clipOut = new Clip();
clipOut.path = new File(outputFilePath).getCanonicalPath();
ffmpegController.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false, new ShellUtils.ShellCallback() {
@Override
public void shellOut(String shellLine) {
System.out.println("fc>" + shellLine);
}
@Override
public void processComplete(int exitValue) {
if (exitValue < 0)
System.err.println("concat non-zero exit: " + exitValue);
}
});
</clip></clip>However when run I get the error :

video proccesing : extract frames and encrypt them then insert them back to the video in java using xuggler
24 juillet 2015, par Anas M. JubaraI’m working on a video encryption application .. the main idea is to input the video file to the application and the application should output it in an encrypted form... am using xuggler library to manipulate the video and get to the frames and AES for encryption.
my code works fine for accessing the frames and encrypting them, what i need help with is how to write the encrypted frame back to the video file to replace the original one without corrupting the video file for the video players.
Here is my codepackage xuggler;
