CastingWasapiLoopbackStop event

Previous pageReturn to chapter overviewNext page



Occurs when a WASAPI loopack device, through a call to the the CastingStop method, stops a casting session previously created by one between the CastingCreateFromStreamMixer, CastingWmaPubPointOpenForStreamMixer or CastingWmaNetworkOpenForStreamMixer methods and started through the CastingStart method .


This event may also occur if the connection with the server should die for external reasons: in this case the error code would be reported inside the nResult parameter.


This event is only intended for usage with Windows Vista and later versions.


Further information about management of casting sessions can be found inside the How to use the control as a source for streaming servers like SHOUTcast tutorial.
