Description
|
|
Packit |
a6ee4b |
Applications should create a GstDeviceMonitor when they want
|
|
Packit |
a6ee4b |
to probe, list and monitor devices of a specific type. The
|
|
Packit |
a6ee4b |
GstDeviceMonitor will create the appropriate
|
|
Packit |
a6ee4b |
GstDeviceProvider objects and manage them. It will then post
|
|
Packit |
a6ee4b |
messages on its GstBus for devices that have been added and
|
|
Packit |
a6ee4b |
removed.
|
|
Packit |
a6ee4b |
The device monitor will monitor all devices matching the filters that
|
|
Packit |
a6ee4b |
the application has set.
|
|
Packit |
a6ee4b |
The basic use pattern of a device monitor is as follows:
