a GstBuffer that can then be retrieved with gst_buffer_peek_memory().
GST_BUFFER_DATA(), GST_BUFFER_MALLOCDATA(), GST_BUFFER_FREE_FUNC() and
- GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer. Use the
- memory API to get access to the buffer data. GST_BUFFER_SIZE() can be
- replaced with gst_buffer_get_size() but if also access to the data is
- required, gst_buffer_map() can return both the size and data in one go.
+ GST_BUFFER_SIZE() are gone, along with the fields in GstBuffer.
The most common way to access all the data in a buffer is by using
gst_buffer_map() and gst_buffer_unmap(). These calls require you to specify
the access mode required to the data and will automatically merge and return
a writable copy of the data.

The buffer must be writable (gst_buffer_is_writable()) in order to modify
the fields, metadata or buffer memory. gst_buffer_make_writable() will not
automatically make a writable copy of the memory but will instead increase
