Accessing Buffer Data in GStreamer 1.0

In GStreamer 1.0, the function 'GST_BUFFER_DATA_PTR' is not explicitly declared like in older versions. However, you can still access the data pointer of a buffer using the 'data' member of the 'GstBuffer' structure.

Here's an example of how you can get the data pointer in GStreamer 1.0:

GstBuffer *buffer;
guint8 *data;

// Obtain a buffer
buffer = ...;

// Get the data pointer
data = GST_BUFFER_DATA(buffer);

The 'GST_BUFFER_DATA' macro expands to access the 'data' member of the 'GstBuffer' structure.
