<doc xml:space="preserve" filename="../subprojects/gst-plugins-bad/gst-libs/gst/basecamerabinsrc/gstbasecamerasrc.c">Base class for the camera source bin used by camerabin for capture.
Sophisticated camera hardware can derive from this baseclass and map the
features to this interface.
The design mandates that the subclasses implement the following features and
behaviour:
* 3 pads: viewfinder, image capture, video capture
During `construct_pipeline()` vmethod a subclass can add several elements into
the bin and expose 3 srcs pads as ghostpads implementing the 3 pad templates.
However the subclass is responsible for adding the pad templates for the
source pads and they must be named "vidsrc", "imgsrc" and "vfsrc". The pad
templates should be installed in the subclass' class_init function, like so:
|[
static void
my_element_class_init (GstMyElementClass *klass)
{
GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
// pad templates should be a #GstStaticPadTemplate with direction
// #GST_PAD_SRC and name "vidsrc", "imgsrc" and "vfsrc"
gst_element_class_add_static_pad_template (gstelement_class,
&vidsrc_template);
gst_element_class_add_static_pad_template (gstelement_class,
&imgsrc_template);
gst_element_class_add_static_pad_template (gstelement_class,
&vfsrc_template);
// see #GstElementDetails
gst_element_class_set_details (gstelement_class, &details);
}
]|
It is also possible to add regular pads from the subclass and implement the
dataflow methods on these pads. This way all functionality can be implemented
directly in the subclass without extra elements.
The src will receive the capture mode from `GstCameraBin2` on the
#GstBaseCameraSrc:mode property. Possible capture modes are defined in
#GstCameraBinMode.</doc>
