Original commit message from CVS: * docs/pwg/advanced-types.xml: Fix description for buffer-frames=0. * docs/gst/tmpl/gstbin.sgml: * gst/gstbin.c: (gst_bin_child_state_change_func), (gst_bin_change_state), (gst_bin_change_state_norecurse): * gst/gstbin.h: * testsuite/threads/Makefile.am: * testsuite/threads/threadi.c: (cb_timeout), (cb_quit), (cb_eos), (cb_state), (cb_play), (main): Fix non-recursive state changes to *really* change the state of the object, and not just call parent_class->state_change. Fix a lot of lockups caused by this. Fixes #132775. Add test for the problem. Also enable test to show #142588 (fixed). * gst/gstthread.c: (gst_thread_change_state), (gst_thread_child_state_change): Don't exit the thread if we go to NULL and are inside thread context. Instead, return control to the main thread context and exit from there. * gst/gstelement.c: (gst_element_disable_threadsafe_properties): Don't unset virtual functions, since those may still be used. That's not necessarily correct, but suffices for now. * configure.ac: * testsuite/Makefile.am: * testsuite/pad/Makefile.am: * testsuite/pad/chainnopull.c: (gst_test_sink_class_init), (gst_test_sink_base_init), (gst_test_sink_chain), (gst_test_sink_init), (main): * testsuite/pad/getnopush.c: (gst_test_src_class_init), (gst_test_src_base_init), (gst_test_src_get), (gst_test_src_init), (main): * testsuite/pad/link.c: (gst_test_element_class_init), (gst_test_element_base_init), (gst_test_src_get), (gst_test_src_loop), (gst_test_src_init), (gst_test_filter_chain), (gst_test_filter_loop), (gst_test_filter_init), (gst_test_sink_chain), (gst_test_sink_loop), (gst_test_sink_init), (cb_error), (main): Add tests to show #150546. Pass, but should fail (currently disabled from the testsuite). * gst/gstscheduler.c: (gst_scheduler_dispose): Dereference child schedulers on dispose (#94464). * testsuite/bytestream/filepadsink.c: (gst_fp_sink_init): Fix typo. * testsuite/threads/thread.c: (main): Add more debug.

* GstBinFlags:

* @GST_BIN_FLAG_MANAGER: this bin is a manager of child elements, i.e.
|
|
* a pipeline or thread.
|
|
* @GST_BIN_SELF_SCHEDULABLE: the bin iterates itself.
|
|
* @GST_BIN_FLAG_PREFER_COTHREADS: we prefer to have cothreads when its
|
|
* an option, over chain-based.
|
|
* @GST_BIN_FLAG_FIXED_CLOCK: bin has one clock that cannot be changed.
|
|
* @GST_BIN_STATE_LOCKED: indicator that we are in a non-recursive
|
|
* state-change on the bin, or that kids should not change parent state.
|
|
* Both are internally used to prevent infinitely recursive loops of
|
|
* state changes. Since they are mutually exclusive and serve the same
|
|
* purpose, we use the same flag for them.
|
|
* @GST_BIN_FLAG_LAST: the last enum in the series of flags in a bin,
|
|
* derived classes can use this as first value in a list of flags.
|
|
*
|
|
* GstBinFlags are a set of flags specific to bins. Most are set/used
|
|
* internally. They can be checked using the GST_FLAG_IS_SET () macro,
|
|
* and (un)set using GST_FLAG_SET () and GST_FLAG_UNSET ().
