Class: SabrStreamingAdapter
Defined in: src/core/SabrStreamingAdapter.ts:76
Adapter class that handles YouTube SABR integration with media players (e.g., Shaka Player).
What it does:
- Sets up request/response interceptors so proper SABR requests can be sent (UMP response parsing must be done in the player adapter).
- Keeps track of initialized formats and their metadata.
- Handles SABR-specific things, such as redirects, context updates, and playback cookies.
