Original commit message from CVS: 2005-02-22 Andy Wingo <wingo@pobox.com> * gst/elements/gstidentity.h * gst/elements/gstidentity.c (gst_identity_handle_buffer): New proc, factored out of the old chain func. (gst_identity_chain): Use handle_buffer. Lock the stream. (gst_identity_getrange): Lock the stream. Still doesn't do any reporting tho. (gst_identity_event): Handle flush events in the loop-based and decoupled cases. (identity_queue_flush, identity_queue_pop, identity_queue_push): New procs, implement a 1-data buffer pen between threads in decoupled operation. (gst_identity_class_init, gst_identity_get_property) (gst_identity_set_property): Use PROP_FOO instead of ARG_FOO. It's not null if we get it, but I might remove five year old code. Add has-src-loop, has-sink-loop, has-chain, has-getrange properties, remove loop-based. (gst_identity_finalize): Free mutex and cond. (gst_identity_init): Alloc mutex and cond. (gst_identity_sink_loop, gst_identity_src_loop): New procs. (gst_identity_set_dataflow_funcs): New proc.
