* The theory of operation is like this: All buffers received are put

- * in chunks of the desired size using gst_adapter_peek(). After the data is
- * processed, it is freed using gst_adapter_flush().
+ * in chunks of the desired size using gst_adapter_map()/gst_adapter_unmap()
+ * and/or gst_adapter_copy(). After the data has been processed, it is freed
+ * using gst_adapter_unmap().
*
* Other methods such as gst_adapter_take() and gst_adapter_take_buffer()
- * combine gst_adapter_peek() and gst_adapter_flush() in one method and are
+ * combine gst_adapter_map() and gst_adapter_unmap() in one method and are
* potentially more convenient for some use cases.
*
* For example, a sink pad's chain function that needs to pass data to a library
* gst_adapter_push (adapter, buffer);
* // while we can read out 512 bytes, process them
* while (gst_adapter_available (adapter) >= 512 && ret == GST_FLOW_OK) {
+ * const guint8 *data = gst_adapter_map (adapter, 512);
* // use flowreturn as an error value
- * ret = my_library_foo (gst_adapter_peek (adapter, 512));
