The project also contains simple scripts that completes the pipeline from video files to GitHub activity.

User Guide

TLDR;

Usage: bash end_to_end.sh "VIDEO_FILE.mp4" | "YOUR SYSTEM'S CLIPBOARD UTILITY"

MacOS: bash end_to_end.sh "VIDEO_FILE.mp4" | pbcopy

Linux: bash end_to_end.sh "VIDEO_FILE.mp4" | xclip

Then simply paste the copied data into the browser console.

Conversion of video to frames

Usage: python extract_frames.py "VIDEO_FILE.mp4"

The above script will create a folder video_frames, and dump all the image frames from the video file into it.

Conversion of frames to array

There is a choice between using compressed data or uncompressed data.
Compressed data requires more pre-processing, but code injection will be quicker, vice versa for uncompressed data.

(Lossless) Compressed data

Usage: python dump_compressed_data.py

The above script will search the video_frames array and dump the base64 encoded data to standard output.
The data is precompressed with Huffman encoding

Example output can be seen in frame_data_compressed.

Uncompressed data

Usage: python dump_data.py

The above script will search the video_frames array and dump the formatted (Javascript) array string to standard output.

Users are advised to redirect the output to their clipboard utility to prepare for the next step, as per below.

MacOS: python dump_data.py | pbcopy

Linux: python dump_data.py | xclip

Injection of Javascript into browser

  1. Navigate to your desired GitHub profile
  2. Open the browser console
  3. Input the data
    • (For compressed data) Type compressedData = followed by the encoded string from the dump. Complete declaration of the variable.
    • (For uncompressed data) Type videoArr = followed by the array string obtained by the dump. Complete declaration of the variable.
      NOTE: This step is likely to freeze the browser for a while if the array is large.
  4. Insert the script in github_activity_animator.js into the console.
    Tweak the FPS in the script if need be.
  5. Enjoy
