Rewind to past moments in live streams and download or play excerpts

Ytpb is a playback for YouTube live streams written in Python. It lets you go back to past moments beyond the limits of the web player. You can keep selected moments by downloading excerpts or play them instantly in your video player via MPEG-DASH.

Check out also mpv-ytpb <https://github.com/xymaxim/mpv-ytpb>__ to play and rewind live streams interactively without leaving a player.

Features

• Download audio and/or video excerpts

  • Save excerpts in different available audio and video formats
  • Precisely cut to exact moments without slow re-encoding

• Play and rewind instantly via MPEG-DASH
