If that block is entered, then start_time becomes GST_CLOCK_TIME_NONE.
Since start_time is invalid, the code will enter the block at line 434 and
new_base_time will be set there.
Move the checks for using an unscheduled entry from the unsafe GstClock to the
SystemClock object so that we can perform the correct locking.
fix a leak and potential deadlock then the async thread fails to start.
Sprinkle some G_LIKELY around because we can.
Keep a counter for the amount of outstanding wakeups that we produce and only
perform a write/read to the control socket when 1 or 0 respectively.
don't poll when waiting for the entries to be unblocked and clear their wakeup
counts, just act on the signal when the wakeup count is 0.
unscheduled entries will clear their wakeup count themselves.
Keep track of when we wakeup the async thread because the list of entries has
changed.
don't try to see if the list changed because we can't really know when one entry
is added multiple times.
Only wake up the async thread when we add an async entry to the head of the list
and the old entry was BUSY.
when an entry being waited on in the async thread is unscheduled, clear the
wakeup queue so we can continue waiting on other entries.
When an entry being waited on in the async thread is unlocked because an earlier
entry was added to the list, set the entry to OK again. This makes sure that
only the entries being waited on have the BUSY flag set and wake up the timer
poll when they are unscheduled.
Add some cleanups to the system clock tests, to free all the memory and
unschedule/unref all clock IDs we allocate.
Use a mutex in one test to avoid potential threading problems on multicore
machines.
Yes, 'codec' isn't exactly the best word, but let's be consistent with AUDIO_CODEC
and VIDEO_CODEC (which may be 'raw' formats as well after all). Prerequisite for
bug #576552.
Running configure with e.g. --disable-dst-debug was compiling out the debug
system (ABI break). Now stubs are added and only if one does e.g.
make CFLAGS="-DGST_REMOVE_DISABLED" the symbols are ommitted.
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.
When generating arrays of control changes timestamp variable was used instead
the local ts variable that we increment when stepping through the array.
