An “award winning software” program (their words, not mine) is VDownloader. Be careful when installing as it installs third-party software, so make sure to uncheck everything during the install. Windows only installation 🙁
It seemed to catch URLs that I copied on Chaturbate (albeit the previous one) and offered to start downloading. Otherwise, it has a built in browser and catches when you watch a cam. Once you start a download, there is no way to stop it, only cancel it.
Still under review.
