Video Channel Authorization [MSDK Only]

[MSDK Only] MSDK wraps the WeChat Channels authorization interface. By calling the ChannelPermissionAuth interface, currently WeChat requires passing snsapi_channels_livestream. In MSDK’s callback, obtain tdiAuthBuffer for subsequent live stream login. This feature does not impose restrictions on the login channel or login status, meaning the interface can be invoked across platforms.

note

• Currently only supports: "WeChat"
• Currently, please set the permission list to snsapi_channels_livestream. This also serves as the marker for distinguishing normal login from permission requests at the lower level. WeChat may update the required permissions in the future
• In the video account authorization callback, tdiAuthBuffer is present in the extraJson field, returned in Base64 format. Parse it via JSON and use standard Base64 decoding
• Timeout callback logic is not supported yet
• MSDK only returns tdiAuthBuffer. Contact WeChat points [jaryqiu] and [gisonyang] to check actual usage.
