daecaf0e8a Remove GST_DEBUG_FUNCPTR where they're pointless
There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.

a8e03abd17 gst/base/basesink: Remove dead assignment.
The code was previously:
* checking if ret was != OK
* .. but if it was FLOW_STEP, swith it to OK
* .. and then not using ret

Instead we just make it more compact by checking if it's OK or STEP.

6e633cbe33 basesink: update segment start/stop for clipping
When we start stepping, store the start/stop values of the segment before we
install new start/stop values for clipping in non-flushing steps.

for non-flushing steps, update the element start time. For flushing steps, it
does not change because running_time does not advance

Make sure we always perform the stop_stepping operations even when we drop
frames.

89c42f8506 stepping: do flushing steps correctly
Note in the docs that a flushing step in PLAYING brings the pipeline to the lost
state and skips the data before prerolling again.

Implement the flushing step correctly by invalidating the current step
operation, which would activate the new step operation.

13f8041238 basesink: fix once-per-second 'emergency rendering' for case where all buffers but the very first are late
Due to a typo basesink didn't do any emergency rendering of late buffers
if the only buffer ever rendered was the first one with timestamp 0. This
means that in cases where the decoder is very very slow, we'd never see
any buffers but the very first one rendered. Fixes #576381.

805569c873 Don't forward LATENCY event when not ready

also don't try to forward the latency event because that might cause unexpected
errors when upstream is not yet linked.

fe4233120c GstBaseSink: avoid calling preroll multiple times
Fix a regression introduced by fix for #567725 in commit
1c7ab4ed4f. We should only call the preroll
function once namely when we did not yet commit the state change.

Add a unit test to check that we call the preroll function when interrupting the
clock_wait (see #567725).
