This plugin writes incoming data to a custom GIO GOutputStream.
It can, for example, be used to write a stream to memory with a GMemoryOuputStream or to write to a file with a GFileOuputStream.
The following example writes the received data to a GMemoryOutputStream.
#include <gst/gst.h>
#include <gio/gio.h>
...
GstElement *sink;
GMemoryOuputStream *stream;
// out_data will contain the received data
guint8 *out_data;
...
stream = G_MEMORY_OUTPUT_STREAM (g_memory_output_stream_new (NULL, 0,
(GReallocFunc) g_realloc, (GDestroyNotify) g_free));
sink = gst_element_factory_make ("giostreamsink", "sink");
g_object_set (G_OBJECT (sink), "stream", stream, NULL);
...
// after processing get the written data
out_data = g_memory_ouput_stream_get_data (G_MEMORY_OUTPUT_STREAM (stream));
...
