Detailed Description

Superclass of all handlers of pause events.

A subclass gets registered via mi::rtmp::IStream::register_pause_event_handler() and will be called in the case of a pause event which can be either pause or resume.

Member Function Documentation

 handle()

virtual bool mi::rtmp::IPause_event_handler::handle ( bool  is_pause,
IStream stream 
)
pure virtual

Called on a pause or resume event.

The event handler allows to filter pause or resume events. If it returns true the render loop for the corresponding stream is affected as follows. If is_pause is true the render event handler will not be called anymore. If is_pause is false the render event handler will again be called as often as indicated by the maximum render rate for the stream. If the pause event handler returns false nothing changes.

Pause/resume events are similar to play/stop events but are less expensive w.r.t. the internal state of the RTMP server.

Note
The stream parameter is only valid during the call of the handle() method and cannot be stored (even if proper reference counting is used).
Parameters
is_pausetrue indicates a pause event, false indicates a resume event.
streamThe stream on which to pause or resume playing.
Returns
true if the event should be honored, or false if should be ignored.
