Start a RequestReceiving method call.

<p>Request that a remote contact stops or starts sending on this stream.</p> <p>The <tp:member-ref>CanRequestReceiving</tp:member-ref> property defines whether the protocol allows the local user to request the other side start sending on this stream.</p>

`proxy` : | the TpProxy
`timeout_ms` : | the timeout in milliseconds, or -1 to use the default
`in_Contact` : | Used to pass an 'in' argument: <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>Contact from which sending is requested</p> (TpContactHandle)
`in_Receive` : | Used to pass an 'in' argument: <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>If true, request that the given contact starts to send media. If false, request that the given contact stops sending media.</p>
`callback` : | called when the method call succeeds or fails; may be `NULL` to make a "fire and forget" call with no reply tracking
`user_data` : | user-supplied data passed to the callback; must be `NULL` if `callback` is `NULL`
`destroy` : | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL`
`weak_object` : | If not `NULL`, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be `NULL` if `callback` is `NULL`
Returns : | a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.

Set the stream to start or stop sending media from the local user to other contacts.

`proxy` : | the TpProxy

Connect a handler to the signal LocalCredentialsChanged.

Emitted when the value of <tp:member-ref>LocalCredentials</tp:member-ref> changes to a non-empty value. This should only happen when the streaming implementation calls <tp:member-ref>SetCredentials</tp:member-ref>, so this signal is mostly useful for debugging.
