Description

public File convertToMp4(File file) throws IOException, FrameGrabber.Exception, FrameRecorder.Exception { FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(file); grabber.start(); FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(file, 0); recorder.setFormat("mp4"); recorder.setFrameRate(grabber.getFrameRate()); recorder.setSampleRate(grabber.getSampleRate()); recorder.setVideoCodec(grabber.getVideoCodec()); recorder.setAudioCodec(grabber.getAudioCodec()); recorder.start(); Frame frame; while ((frame = grabber.grabFrame()) != null) { recorder.record(frame); } recorder.stop(); recorder.release(); grabber.stop(); grabber.release();

}  guys, please tell me what I'm doing wrong, I'm trying to convert these files to mp4 format, point to the errors, the user from the web application will convert his video file to mp4.

Research direction
Inspect the code: the same File object is used for both reading and writing. Create a separate output file for the MP4 conversion to avoid overwriting the original.
