## What it is
DDTV is a cross-platform tool for Bilibili live streams offering multi-window viewing, stream-start notifications, automatic recording with danmaku/SC/gift capture, and automatic file merging and transcoding. It ships as a .NET Core library, an ASP.NET server with an authenticated API and WebUI, and a Windows WPF desktop client.

## Use cases
- watch multiple bilibili live streams at once
- get notified when a streamer goes live
- automatically record bilibili live streams
- record danmaku and super chats with the stream
- merge and transcode recorded stream files
- self-host a bilibili live monitoring webui

## When to choose
- you follow bilibili streamers and never want to miss a broadcast
- you need reliable timeline-accurate recording including danmaku and gifts
- you want a self-hosted webui or API for automation and secondary development

## When to avoid
- you record platforms other than bilibili
- you need a lightweight headless recorder without a webui
- you require a permissive license (it is GPL-2.0)
