FFmpeg on Android

Question

I have got FFmpeg compiled (libffmpeg.so) on Android. Now I have to build either an application like RockPlayer or use existing Android multimedia framework to invoke FFmpeg

Answer 1

Strange that this project hasn't been mentioned: AndroidFFmpeg from Appunite

It has quite detailed step-by-step instructions to copy/paste to command line, for lazy people like me ))

Answer 2

After a lot of research, right now this is the most updated compiled library for Android that I found:

https://github.com/bravobit/FFmpeg-Android

• At this moment is using FFmpeg release n4.0-39-gda39990
• Includes FFmpeg and FFProbe
• Contains Java interface to launch the commands
• FFprobe or FFmpeg could be removed from the APK, check the wiki https://github.com/bravobit/FFmpeg-Android/wiki

Answer 3

To make my FFMPEG application I used this project (https://github.com/hiteshsondhi88/ffmpeg-android-java) so, I don't have to compile anything. I think it's the easy way to use FFMPEG in our Android applications.

Answer 4

First, add the dependency of FFmpeg library

implementation 'com.writingminds:FFmpegAndroid:0.3.2'

Then load in activity

FFmpeg ffmpeg;
    private void trimVideo(ProgressDialog progressDialog) {

    outputAudioMux = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES).getAbsolutePath()
            + "/VidEffectsFilter" + "/" + new SimpleDateFormat("ddMMyyyy_HHmmss").format(new Date())
            + "filter_apply.mp4";

    if (startTrim.equals("")) {
        startTrim = "00:00:00";
    }

    if (endTrim.equals("")) {
        endTrim = timeTrim(player.getDuration());
    }

    String[] cmd = new String[]{"-ss", startTrim + ".00", "-t", endTrim + ".00", "-noaccurate_seek", "-i", videoPath, "-codec", "copy", "-avoid_negative_ts", "1", outputAudioMux};


    execFFmpegBinary1(cmd, progressDialog);
    }



    private void execFFmpegBinary1(final String[] command, ProgressDialog prpg) {

    ProgressDialog progressDialog = prpg;

    try {
        ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
            @Override
            public void onFailure(String s) {
                progressDialog.dismiss();
                Toast.makeText(PlayerTestActivity.this, "Fail to generate video", Toast.LENGTH_SHORT).show();
                Log.d(TAG, "FAILED with output : " + s);
            }

            @Override
            public void onSuccess(String s) {
                Log.d(TAG, "SUCCESS wgith output : " + s);

//                    pathVideo = outputAudioMux;
                String finalPath = outputAudioMux;
                videoPath = outputAudioMux;
                Toast.makeText(PlayerTestActivity.this, "Storage Path =" + finalPath, Toast.LENGTH_SHORT).show();

                Intent intent = new Intent(PlayerTestActivity.this, ShareVideoActivity.class);
                intent.putExtra("pathGPU", finalPath);
                startActivity(intent);
                finish();
                MediaScannerConnection.scanFile(PlayerTestActivity.this, new String[]{finalPath}, new String[]{"mp4"}, null);

            }

            @Override
            public void onProgress(String s) {
                Log.d(TAG, "Started gcommand : ffmpeg " + command);
                progressDialog.setMessage("Please Wait video triming...");
            }

            @Override
            public void onStart() {
                Log.d(TAG, "Startedf command : ffmpeg " + command);

            }

            @Override
            public void onFinish() {
                Log.d(TAG, "Finished f command : ffmpeg " + command);
                progressDialog.dismiss();
            }
        });
    } catch (FFmpegCommandAlreadyRunningException e) {
        // do nothing for now
    }
}

  private void loadFFMpegBinary() {
    try {
        if (ffmpeg == null) {
            ffmpeg = FFmpeg.getInstance(this);
        }
        ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
            @Override
            public void onFailure() {
                showUnsupportedExceptionDialog();
            }

            @Override
            public void onSuccess() {
                Log.d("dd", "ffmpeg : correct Loaded");
            }
        });
    } catch (FFmpegNotSupportedException e) {
        showUnsupportedExceptionDialog();
    } catch (Exception e) {
        Log.d("dd", "EXception no controlada : " + e);
    }
}

private void showUnsupportedExceptionDialog() {
    new AlertDialog.Builder(this)
            .setIcon(android.R.drawable.ic_dialog_alert)
            .setTitle("Not Supported")
            .setMessage("Device Not Supported")
            .setCancelable(false)
            .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finish();
                }
            })
            .create()
            .show();

}

Also use another feature by FFmpeg

===> merge audio to video
String[] cmd = new String[]{"-i", yourRealPath, "-i", arrayList.get(posmusic).getPath(), "-map", "1:a", "-map", "0:v", "-codec", "copy", "-shortest", outputcrop};


===> Flip vertical :
String[] cm = new String[]{"-i", yourRealPath, "-vf", "vflip", "-codec:v", "libx264", "-preset", "ultrafast", "-codec:a", "copy", outputcrop1};


===> Flip horizontally :  
String[] cm = new String[]{"-i", yourRealPath, "-vf", "hflip", "-codec:v", "libx264", "-preset", "ultrafast", "-codec:a", "copy", outputcrop1};


===> Rotate 90 degrees clockwise:
String[] cm=new String[]{"-i", yourRealPath, "-c", "copy", "-metadata:s:v:0", "rotate=90", outputcrop1};


===> Compress Video
String[] complexCommand = {"-y", "-i", yourRealPath, "-strict", "experimental", "-vcodec", "libx264", "-preset", "ultrafast", "-crf", "24", "-acodec", "aac", "-ar", "22050", "-ac", "2", "-b", "360k", "-s", "1280x720", outputcrop1};


===> Speed up down video
String[] complexCommand = {"-y", "-i", yourRealPath, "-filter_complex", "[0:v]setpts=2.0*PTS[v];[0:a]atempo=0.5[a]", "-map", "[v]", "-map", "[a]", "-b:v", "2097k", "-r", "60", "-vcodec", "mpeg4", outputcrop1};
String[] complexCommand = {"-y", "-i", yourRealPath, "-filter_complex", "[0:v]setpts=1.0*PTS[v];[0:a]atempo=1.0[a]", "-map", "[v]", "-map", "[a]", "-b:v", "2097k", "-r", "60", "-vcodec", "mpeg4", outputcrop1};
String[] complexCommand = {"-y", "-i", yourRealPath, "-filter_complex", "[0:v]setpts=0.75*PTS[v];[0:a]atempo=1.5[a]", "-map", "[v]", "-map", "[a]", "-b:v", "2097k", "-r", "60", "-vcodec", "mpeg4", outputcrop1};
String[] complexCommand = {"-y", "-i", yourRealPath, "-filter_complex", "[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]", "-map", "[v]", "-map", "[a]", "-b:v", "2097k", "-r", "60", "-vcodec", "mpeg4", outputcrop1};



===> Add two mp3 files 

StringBuilder sb = new StringBuilder();
sb.append("-i ");
sb.append(textSngname);
sb.append(" -i ");
sb.append(mAudioFilename);
sb.append(" -filter_complex [0:0][1:0]concat=n=2:v=0:a=1[out] -map [out] ");
sb.append(finalfile);
---> ffmpeg.execute(sb.toString().split(" "), new ExecuteBinaryResponseHandler()




===> Add three mp3 files

StringBuilder sb = new StringBuilder();
sb.append("-i ");
sb.append(firstSngname);
sb.append(" -i ");
sb.append(textSngname);
sb.append(" -i ");
sb.append(mAudioFilename);
sb.append(" -filter_complex [0:0][1:0][2:0]concat=n=3:v=0:a=1[out] -map [out] ");
sb.append(finalfile);
---> ffmpeg.execute(sb.toString().split(" "), new ExecuteBinaryResponseHandler()
