How to download MP2T video (from Twitch, for example)?
Open the channel page on Twitch and start playing the video. Click on the add-on button, select the desired video quality for recording (Sourch, High, Medium, Low, Mobile) and click on Start Recording.
The video will start recording, and you will see the add-on icon change.
When you are done watching the channel, click on the add-on button and then click on Stop Recording.
Wait for the small video fragments (sites like Twitch transmit videos in fragments) to be joined into a single one. When the process is completed, you will see a message letting you know the video is ready and you can open it.
