Merge audio and video

[choijuho78]

String[] cmd = new String[]{"-i",videoFile.getAbsolutePath(),"-i",audioFile.getAbsolutePath(),"-strict","experimental","-c","copy","-map","0:v","-map","1:a",file.getAbsolutePath()}; Controller.getInstance().run(cmd);

Then app terminated. Help me please.

If by merging you mean removing video-audio and adding new audio then try

String[] cmd = new String[]{"-i",videoFile.getAbsolutePath(),"-i",audioFile.getAbsolutePath(),"-strict","experimental","-c:v","copy","-c:a","aac","-map","0:v","-map","1:a",file.getAbsolutePath()};

Above command will re-encode audio; If above not working then try to re-encode video too.

String[] cmd = new String[]{"-i",videoFile.getAbsolutePath(),"-i",audioFile.getAbsolutePath(),"-strict","experimental","-c:v","libx264","-c:a","aac","-map","0:v","-map","1:a",file.getAbsolutePath()};

If both commands are not working then post some logs. It will help to identify issue.

Please post some logs. It will help to identify problems. Following are some of my guesses.

1. It could be that ffmpeg lib is not installed properly.
2. Files are not in specified path.
3. Code needs to run in background process.

Logs would help to identify problem.

It is library problem. Library does not support libx264 correctly.
