## Detailed Description

An end of stream event.

See create() for more details.

## Member Function Documentation

static Glib::RefPtr<Gst::EventEos> Gst::EventEos::create | ( |  | ) |
| static

Create a new EOS event.

The eos event can only travel downstream synchronized with the buffer flow. Elements that receive the EOS event on a pad can return Gst::FLOW_UNEXPECTED as a Gst::FlowReturn when data after the EOS event arrives.

The EOS event will travel down to the sink elements in the pipeline which will then post the Gst::MESSAGE_EOS on the bus after they have finished playing any buffered data.

When all sinks have posted an EOS message, an EOS message is forwarded to the application.

Returns
  The new EOS event.
