The script downloads videos from boomstream.com streaming service.

The service stores video chunks encrypted using HLS AES-128 algorithm. In order to decrypt them AES initialization vector and 128-bit key are required. Initialization vector is encrypted in the first part of #EXT-X-MEDIA-READY variable which is contained in m3u8 playlist using a simple XOR operation. The key is supposed to be recevied via HTTP using a URL that starts with https://play.boomstream.com/api/process/ and contains a long hex key that can be computed using session token and the second part of #EXT-X-MEDIA-READY.

Spicify --url and --pin in command line arguments:

https://play.boomstream.com/TiAR7aDs?ppv=EswAWlFa --pin 123-456-789

You can also specify a resolution using --resolution command line argument:

https://play.boomstream.com/TiAR7aDs?ppv=EswAWlFa --pin 123-456-789 --resolution "640x360"

If resolution is not specified, the video with a highest one will be dowloaded.

• openssl
• curl
• python-requests
• lxml
• ffmpeg (for enconding ts -> mp4)

As the script was written and tested in Linux (specifically Ubuntu 18.04.4 LTS) it uses GNU/Linux cat tool to merge the video pieces into one single file. I think this is the only thing that prevents it from running in Windows. If you have time to make a PR to fix that I will really appreciate.
