StreamBuffRe

View Media Streams With External Players
StreamBuffRe (Buffer and Redirect Streams) is a tool to buffer media streams and redirect them to an external media player like MPV Player, VLC or others. It can handle URLs pointing directly to media streams, as well as links from various video sites, including YouTube, Vimeo, Twitch and others.
To add a stream, simply paste the URL and it is added to the playlist from where you can play it with an external player or download it to your disk. You can buffer a stream while watching another and also open multiple stream in different players simultaneously.
Other features include built-in conversion (using FFMPEG as the default), remote control via HTTP interface, favorite streams, support for external plug-ins, customizable player profiles, and more.
The trial version can be used for free with some feature limitations.
