[PATCH v3 2/3] bap.c: Add support for multiple BISes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Update broadcast to support the new setup structure.
Change broadcast code from iovec struct to byte array.
Add adapter property for broadcast endpoint.
Make broadcast sink to select broadcast source BISes
based on pac broadcast sink properties.
