Original commit message from CVS: 2005-08-26 Andy Wingo <wingo@pobox.com> * check/pipelines/simple_launch_lines.c (run_pipeline): Check element_set_state's return val. (test_2_elements): Add test that's been disabled for months. * gst/elements/gstfakesink.c: Cleanups. Add can-activate-push and can-activate-pull properties. * gst/elements/gstfakesrc.c: Cleanups. Add can-activate-push and can-activate-pull properties. Implement is_seekable so fakesrc can operate in pull mode. * gst/base/gstbasesink.c (GstBaseSink): Remove has-loop, has-chain properties. (gst_base_sink_activate, gst_base_sink_activate_pull) (gst_base_sink_activate_push): Make activation mode choosing work. Cleanups. (gst_base_sink_chain, gst_base_sink_loop): Assert activation mode is right. Make pull mode work. Post an eos before pausing in pull mode. (gst_base_sink_change_state): Pay attention to the core's change_state() return val. * gst/base/gstbasesrc.c (GstBaseSrc): Remove has-loop, has-getrange properties. Cleanups. * gst/base/gstbasesrc.h (GstBaseSrc): Remove has_loop, has_getrange and replace with can_activate_pull and can_activate_push. * gst/base/gstbasesink.h (GstBaseSink): Rearrange fields, add locking comments. Remove has_loop, has_chain and replace with can_activate_pull and can_activate_push.
