a78857c296 Improve _adjust_unlocked() so that it overflows less.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
* gst/gstclock.c: (gst_clock_adjust_unlocked),
(gst_clock_unadjust_unlocked), (gst_clock_set_calibration):
* gst/gstclock.h:
Improve _adjust_unlocked() so that it overflows less.
Add gst_clock_unadjust_unlocked to convert from external time to
internal time based on calibration.
Add some more debug.

most clock implementations.
Document vmethods.
Flesh out docs about resolution methods.
API: GstClockClass::wait_jitter

Original commit message from CVS:

(gst_clock_id_wait_async), (gst_clock_id_unschedule),
(gst_clock_init), (gst_clock_get_internal_time),
(gst_clock_set_master), (do_linear_regression),

* gst/gstclock.h:
Review docs.
Small cleanups.
Fix a possible segfault when the window-size is made smaller.
Calculate jitter before performing the clock wait. Ideally
the clock implementation should calculate jitter but we need
API breakage for that.
* gst/gstsystemclock.c: (gst_system_clock_init):
Docs review.
* libs/gst/base/gstbasesink.c: (gst_base_sink_do_sync):
Remove leftover else
* tests/check/gst/gstsystemclock.c: (GST_START_TEST),

Original commit message from CVS:
2005-11-23  Andy Wingo  <wingo@pobox.com>

* check/net/gstnetclientclock.c (test_functioning): Adjust to
rate_num/rate_denom change.

* gst/net/gstnetclientclock.c
(gst_net_client_clock_observe_times): Take the SLAVE_LOCK not the
OBJECT_LOCK. Don't call add_observation with the lock.

* gst/gstclock.c (gst_clock_init): Initialize the rate as a
fraction.
(gst_clock_adjust_unlocked): Adjust using uint64_scale and the
rate fraction.
(gst_clock_set_calibration, gst_clock_get_calibration): Change to
deal with rate as a fraction whose numerator and denominator are
GstClockTime values.
(gst_clock_set_master): Only use the OBJECT_LOCK to set the
master; the other fields are protected by the SLAVE_LOCK.
(do_linear_regression): Note that this must be called with the
SLAVE_LOCK.
(gst_clock_add_observation): Take the SLAVE_LOCK, not the
OBJECT_LOCK. Call set_calibration instead of touching the
variables directly.
(gst_clock_set_property, gst_clock_get_property): Protect
master/slave parameters with the SLAVE_LOCK.

* gst/gstclock.h (GstClock): Remove rate, add rate_numerator and
rate_denominator. PR3C1S3. Add a new lock, the SLAVE_LOCK, and
note that all of the instance variables that add_observation and
the set_master functions use are protected by that lock and not
the OBJECT_LOCK.
(GST_CLOCK_SLAVE_LOCK, GST_CLOCK_SLAVE_UNLOCK): New macros.

* gst/gstclock.c (gst_clock_add_observation): No longer requires
the caller to take the object lock.

* gst/gstbin.c: (gst_bin_set_clock_func), (gst_bin_add_func):

* gst/gstclock.c: (gst_clock_entry_new), (gst_clock_id_wait),

(gst_clock_get_master), (do_linear_regression),
(gst_clock_add_observation), (gst_clock_set_property),
(gst_clock_get_property):
* gst/gstclock.h:
Implement master/slave. When setting a clock as a slave, a
periodic timeout is scheduled to sample master and slave times.
Then the slave clock is recalibrated to match offset and rate
of the master clock.
Update logging a bit.
Add flag so that a clock can state that is cannot be slaved to
another clock.

* gst/gstelement.c: (gst_element_set_clock):
* gst/gstelement.h:
The set_clock returns a gboolean for when an element cannot
deal with the selected clock in the pipeline.

* gst/gstpipeline.c: (gst_pipeline_change_state),
(gst_pipeline_set_clock):
* gst/gstpipeline.h:
Handle the case where the selected clock cannot be set on
the pipeline.

* gst/net/gstnetclientclock.c: (gst_net_client_clock_class_init),
(gst_net_client_clock_init), (gst_net_client_clock_finalize),
(gst_net_client_clock_set_property),
(gst_net_client_clock_get_property),
(gst_net_client_clock_observe_times):
* gst/net/gstnetclientclock.h:
Use regression code in GstClock parent, remove duplicated
functionality.

2005-11-18  Andy Wingo  <wingo@pobox.com>

* gst/net/gstnetclientclock.c (do_linear_regression): Use all
integer arithmetic. Return the minimum of the domain, which can be
set as "internal" for gst_clock_set_calibration.
(gst_net_client_clock_observe_times): Call _set_calibration.
(gst_net_client_clock_new): Call _set_calibration instead of
rate_offset.

* check/net/gstnetclientclock.c (test_functioning): Use the right
adjustment api.

* gst/gstclock.h:
* gst/gstclock.c (gst_clock_get_calibration)
(gst_clock_set_calibration): New functions, obsolete the ones I
added yesterday. Doh. Precision issues mean we have to extrapolate
from a point in the more recent past than 1970.
(gst_clock_get_rate_offset, gst_clock_set_rate_offset): Mark as
obsolete.
(gst_clock_adjust_unlocked): Use the right calibration data.

Original commit message from CVS:
* gst/gstclock.c: (gst_clock_init), (gst_clock_adjust_unlocked),
(gst_clock_set_rate_offset), (gst_clock_get_rate_offset):
* gst/gstclock.h:
Anonymous structs are a gcc (and some other compilers) extension, so
don't use them. Since this is only for ABI-compatibility, and our
API/ABI freeze is over in a few days, this whole thing will only
last a few days, so don't bother trying to think up a meaningful
name for the struct.

for the freeze break.

* gst/gstclock.c (gst_clock_adjust_unlocked): Implement using rate
and offset, trying to keep precision and avoiding
underflow/overflow.
(gst_clock_set_rate_offset, gst_clock_get_rate_offset): New
functions. Make gst_clock_set_time_adjust obsolete.
(gst_clock_set_time_adjust): Note that this function is obsolete.
Will file bug soon.

* gst/gstelement.c (gst_element_dispose): Protect against multiple
invocations.

* gst/schedulers/gstoptimalscheduler.c
I added a mess of prototypes at the top of the file by way of
documentation. Some of the operations on chains and groups were
re-organized.

(create_group): Added a type argument so if the group is enabled,
the setup_group_scheduler knows what to do.
(group_elements): Added a type argument here, too, to be passed on
to create_group.
(group_element_set_enabled): If an unlinked PLAYING element is
added to a bin, we have to create a new group to hold the element,
and this function will be called before the group is added to the
chain. Thus we have a valid case for group->chain==NULL. Instead
of calling chain_group_set_enabled, just set the flag on the group
(the chain's status will be set when the group is added to it).
(gst_opt_scheduler_state_transition, chain_group_set_enabled):
Setup the group scheduler when the group is enabled, not
specifically when an element goes PAUSED->PLAYING. This means
PLAYING elements can be added, linked, and scheduled into a
PLAYING pipeline, as was intended.
(add_to_group): Don't ref the group twice. I don't know when this
double-ref got in here. Removing it has the potential to cause
segfaults if other parts of the scheduler are buggy. If you find
that the scheduler is segfaulting for you, put in an extra ref
here and see if that hacks over the underlying issue. Of course,
then find out what code is unreffing a group it doesn't own...
(create_group): Make the extra refcount floating, and remove it
after adding the element. This means that...
(unref_group): Destroy when the refcount reaches 0, not 1, like
every other refcounted object in the known universe.
(remove_from_group): When a group becomes empty, set it to be not
active, and remove it from its chain. Don't unref it again,
there's no floating reference any more.
(destroy_group): We have to remove the group from the chain in
remove_from_group (rather than here) to break refcounting cycles
(the chain always has a ref on the group). So assert that
group->chain==NULL.
(ref_group_by_count): Removed, it was commented out anyway.
(merge_chains): Use the remove_from_chain and add_to_chain
primitives to do the reparenting, instead of rolling our own
implementation.
(add_to_chain): The first non-disabled group in the chain's group
list will be the entry point for the chain. Because buffers can
accumulate in loop elements' peer bufpens, we preferentially
schedule loop groups before get groups to avoid unnecessary
execution of get-based groups when the bufpens are already full.
(gst_opt_scheduler_schedule_run_queue): Debug fixes.
(get_group_schedule_function): Ditto.
(loop_group_schedule_function): Ditto.
(gst_opt_scheduler_loop_wrapper): Ditto.
(gst_opt_scheduler_iterate): Ditto.

I understand the opt scheduler now, yippee!

add concept of "element time" and functions to get/set this time.
* gst/gstelement.c: (gst_element_change_state):
update element time correctly.
* gst/gstelement.c: (gst_element_get_compatible_pad_filtered):
This is a debug message, not a g_critical.

handle discontinuous events right with element time.
* gst/gstscheduler.c: (gst_scheduler_state_transition):
update to clocking fixes.
set clocks on elements in READY=>PAUSED. The old behaviour caused
a wrong element time on the first element that started playing.
