Code Output:

Video encoding complete. Output saved to: /path/to/output/video.mov

Code Explanation:

The program starts by importing the necessary classes. It primarily uses the jcodec library to handle the video encoding. Here’s a step-by-step breakdown of the code:

1. Define the RealTimeVideoEncoder class with fields for SequenceEncoder and outputPath.
2. The constructor takes in the path for the output video file and initializes the SequenceEncoder with it. It sets the output video format to MOV using the jcodec library functions.
3. The method encodeImage takes a BufferedImage as input, which represents a single frame to be encoded. It uses AWTUtil.fromBufferedImage to convert BufferedImage to Picture format that jcodec can understand and encodes it into a video frame.
4. finishEncoding is called after all frames have been processed. It finalizes the video file, making it ready for playback.
5. The main method demonstrates how to use the RealTimeVideoEncoder. It first initializes the encoder with a sample output file path. Then, it loops 100 times, simulating the encoding of 100 video frames. In a real scenario, the images would be captured or created in real-time.
6. Inside the loop, it reads individual frames from a specified path (this is just placeholder code—in an actual application, the images would likely come from a video capture device).
7. It encodes each image as a video frame by calling encodeImage.
8. After all frames are encoded, it calls finishEncoding to wrap up and finalize the video file.
9. The program prints a message upon successful encoding of the video.

Overall, the architecture allows for easy integration into a system that requires real-time video encoding capabilities, useful, for example, in video streaming applications. The built-in loop simulates a scenario where frames are being encoded on-the-fly, which showcases the encoder’s potential in a live environment.
