Original commit message from CVS: Patch from vishnu: The attached patch adds event support to bytestream. Here's how it works: When bytestream encounters an event, the event is saved and it returns NULL. Then you must call a new API to retrieve the event and handle it: void gst_bytestream_get_status (GstByteStream *bs, guint32 *avail_out, GstEvent **event_out); Whatever is necessary to handle the event is left up to the plugin. Once the event is retrieved then the bytestream continues as usual.
