Methods

buildAuthToken_(token) → {Uint8Array}

Parameters:
Name Type Description
token string
Source:
Returns:
Type
Uint8Array

connect(webTransportnon-null, confignon-null, authorizationTokenopt, nullable) → {Promise<!shaka.extern.MsfSession>}

Performs this draft's setup handshake over an established WebTransport connection and returns the resulting session. The handshake is part of the dialect because it is not stable across drafts: draft-16 opens a single bidirectional stream and exchanges CLIENT_SETUP and SERVER_SETUP over it, while draft-17 collapsed the two into one SETUP message sent on each of a pair of unidirectional streams.
Parameters:
Name Type Attributes Description
webTransport WebTransport
config shaka.extern.MsfManifestConfiguration
authorizationToken string <optional>
<nullable>

The primitive codec for this draft, which encodes and decodes the variable-length integers every other field is built from.
