Original commit message from CVS: * examples/app/Makefile.am: * examples/app/appsrc-ra.c: (feed_data), (seek_data), (found_source), (bus_message), (main): * examples/app/appsrc-seekable.c: (feed_data), (seek_data), (found_source), (bus_message), (main): * examples/app/appsrc-stream2.c: (feed_data), (found_source), (bus_message), (main): Added 3 more example application for using appsrc in random-access mode, pull-mode streaming and pull mode seekable. * gst-libs/gst/app/gstappsrc.c: (gst_app_src_class_init), (gst_app_src_start), (gst_app_src_do_get_size), (gst_app_src_create): * gst-libs/gst/app/gstappsrc.h: Make stream-type property writable. Unset flushing when starting so that we reuse appsrc. Inform basesrc about the configured size. Emit seek-data signal when we are going to a different offset in random-access mode.
