This software allows you to download HLS video streams from GetCourse without loss of quality, without the need for transcoding, and to merge them into a single video file. The program is written in Go language and is designed for use in Mac OS X operating system.
The bin folder contains the compiled version.
Software requires ffmpeg to work.
If you do not have Homebrew installed, run the following commands in the terminal, otherwise skip this paragraph.
Run this command to install Homebrew:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Then install FFmpeg using this command (terminal):
brew install ffmpeg
Then verify that the installation completed successfully:
ffmpeg -version
- Open the page with the video in Chromium / Google Chrome browser.
- Right-click on the video, select "View Code".
- In the developer panel that opens, open the "Network" tab.
- Reload the page in your browser.
- Select the desired video resolution in the GetCourse video player settings.
- Start playing the video, let it play for a couple of seconds, then pause it.
- Find and copy the link ("Request URL") to the downloaded file with a number name that matches the resolution of the video in the player (360, 720, 1080, etc.).
Simply download the program binary from the bin directory and run it with the following parameters:
./getcourse-video-downloader <playlist_url> <output_file>, where:
playlist_url — link to HLS video stream playlist
output_file — file name where the final video should be saved (video.mp4)
You know what to do.
The general logic is inspired by mikhailnov, but his solution at the moment of publishing this readme has a significant problem with sound in clips after assembling them (obvious clicks at the beginning of each segment of the HLS video stream).
