Description

Trying to download lives and vods on twitcasting.tv without any luck. Even the index.m3u8 mentioned a few months ago doesn't work anymore.

[Igetin]

The website doesn’t seem to use playlists anymore, or at least there are no requests to an M3U8 file like there used to be.

Just leaving this here for others looking for a solution: streamlink does still support Twitcasting currently… but only for livestreams.

Example usage:

streamlink -o output_file.ts https://twitcasting.tv/USERNAME best

Password-protected stream:

streamlink -o output_file.ts --twitcasting-password password_here https://twitcasting.tv/USERNAME best

Edit: this tool seems to work for VODs as well, including password-protected ones.
