Original commit message from CVS: * docs/design/draft-keyframe-force.txt: Fix typo. * gst/playback/gstqueue2.c: (update_buffering), (gst_queue_handle_src_query): Set buffering mode in the messages. Set buffering percent in the query. * tests/examples/seek/seek.c: (update_fill), (msg_state_changed), (do_stream_buffering), (do_download_buffering), (msg_buffering): Do some more fancy things based on the buffering method in use.
