                           GstBuffer * enhancement_data)

Attaches GstLcevcMeta metadata to buffer.

Parameters:

buffer –

a GstBuffer

enhancement_data –

the parsed LCEVC enhancement data

Returns (GstLcevcMeta *) –

the GstLcevcMeta on buffer.

gst_buffer_get_lcevc_meta

GstLcevcMeta *
gst_buffer_get_lcevc_meta (GstBuffer * buffer)

Find the GstLcevcMeta on buffer with the lowest id.

Buffers can contain multiple GstLcevcMeta metadata items when dealing with multiview buffers.

Parameters:

buffer –

a GstBuffer

Returns (GstLcevcMeta *) –

the GstLcevcMeta with lowest id (usually 0) or NULL when there is no such metadata on buffer.

Since : 1.26

gst_buffer_get_lcevc_meta_id

GstLcevcMeta *
gst_buffer_get_lcevc_meta_id (GstBuffer * buffer,
                              gint id)

Find the GstLcevcMeta on buffer with the given id.

Buffers can contain multiple GstLcevcMeta metadata items when dealing with multiview buffers.

Parameters:

buffer –

a GstBuffer

id –

a metadata id

Returns (GstLcevcMeta *) –

the GstLcevcMeta with id or NULL when there is no such metadata on buffer.

Since : 1.26
