File Encoder/Decoder

This project consists of two main scripts: an encoder that converts files to a series of images and then to a video, and a decoder that reverses this process to recover the original file.

Encoder Usage

The encoder script converts a file into a series of images, which are then compiled into a video.

python encoder.py --encode <path_to_file> [--output <output_video_name>]

Arguments:

• --encode: (Required) Path to the file you want to encode.
• --output: (Optional) Name of the output video file. Default is "output.avi".

Example:

python encoder.py --encode my_secret_file.zip --output encoded_file.avi

This command will:

1. Convert my_secret_file.zip into a series of images.
2. Compile these images into a video named encoded_file.avi.
3. Delete the temporary image files.

Decoder Usage

The decoder script extracts images from a video and reconstructs the original file.

python decoder.py --decode <path_to_video> [--output <output_file_name>]

Arguments:

• --decode: (Required) Path to the video file you want to decode.
• --output: (Optional) Name of the output file. Default is "restored_file.zip".

Example:

python decoder.py --decode encoded_file.avi --output recovered_secret_file.zip

This command will:

1. Extract frames from encoded_file.avi as individual images.
2. Convert these images back into binary data.
3. Save the reconstructed file as recovered_secret_file.zip.
4. Delete the temporary image files.

Notes:

• Ensure you have the required dependencies installed (opencv-python, numpy, Pillow).
• The encoder uses the FFV1 codec for lossless compression.
• The default image size is 1920x1080. Modify IMAGE_SIZE in the scripts if needed.
• Temporary files are automatically cleaned up after processing.
