Functions
gst_sample_get_buffer ()
GstBuffer *
gst_sample_get_buffer (GstSample *sample
);
Get the buffer associated with sample
Returns
the buffer of sample
or NULL when there
is no buffer. The buffer remains valid as long as sample
is valid.
If you need to hold on to it for longer than that, take a ref to
the buffer with gst_buffer_ref()
.
[transfer none]
gst_sample_get_caps ()
GstCaps *
gst_sample_get_caps (GstSample *sample
);
Get the caps associated with sample
Returns
the caps of sample
or NULL when there
is no caps. The caps remain valid as long as sample
is valid.
If you need to hold on to the caps for longer than that, take a ref to
the caps with gst_caps_ref()
.
[transfer none]
gst_sample_get_info ()
const GstStructure *
gst_sample_get_info (GstSample *sample
);
Get extra information associated with sample
.
gst_sample_get_segment ()
GstSegment *
gst_sample_get_segment (GstSample *sample
);
Get the segment associated with sample
gst_sample_new ()
GstSample * gst_sample_new (GstBuffer *buffer
,GstCaps *caps
,const GstSegment *segment
,GstStructure *info
);
Create a new GstSample with the provided details.
Free-function: gst_sample_unref
Parameters
buffer |
a GstBuffer, or NULL. |
[transfer none][allow-none] |
caps |
a GstCaps, or NULL. |
[transfer none][allow-none] |
segment |
a GstSegment, or NULL. |
[transfer none][allow-none] |
info |
a GstStructure, or NULL. |
[transfer full][allow-none] |
gst_sample_ref ()
GstSample *
gst_sample_ref (GstSample *sample
);
Increases the refcount of the given sample by one.
Types and Values
GstSample
typedef struct _GstSample GstSample;
The opaque structure of a GstSample. A sample contains a typed memory block and the associated timing information. It is mainly used to exchange buffers with an application.
