Element base_time is a signed quantity, which leads to basesink returning
a position of 0 when dealing with a negative base time - which are quite
legal when clocks (such as the audio clock) are close to 0.
This doesn't manifest in normal pipelines, of course - but can happen
(at least) when manually setting the base time on a pipeline.
This avoids:
* triple-checking for the GType when type-checking is enabled (see #597260)
* Avoids going through an expensive no-argument checking which landed in
glib-2.22
* Avoids going through 2 extrac functions (g_object_new -> g_object_new_valist)
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.
This avoids having to do the sorting everytime we use typefind
The behaviour of gst_type_find_factory_get_list has subtlely changed
in the sense that the order was previously undefined, whereas now
it returns them sorted by rank and then by name.
Use g_slide instead of nomal g_new, Also don't init struct with 0 as we need to
init it anyway with the real values.
Also join the 3 flags checks into one.
The list against which we run the comparefunc will only contain
GstPluginFeature, therefore remove the 6 expensive type checks we do
for every single comparision.
When we quickly switch from PLAYING to PAUSED and back to PLAYING it's possible
in some cases that the task refuses to start, This is because when we go to
PAUSED, we unschedule the clock timeout, which could return UNSCHEDULED when
we're back to PLAYING, causing the task to PAUSE again with a wrong-state.
This patch checks if we are running when we return with an UNSCHEDULED return
value and if we are, try to create a new buffer.
Fixes#597550
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.
In most places in core and baseclasses we just need the caps to do caps-
intersections. In that case ref'ed caps are enough (no need to copy).
This patch also switches the code to use the new functions.
API: gst_pad_get_caps_refed(), gst_pad_peer_get_caps_refed()
The normal functions are always useful to have for bindings, especially
runtime-created bindings like Seed or new GObject-Introspection based
Python bindings.
Add a simple version check when starting the plugin-scanner so we can
verify we're talking to one that talks the same language.
First try a plugin-scanner in the installed path, then try one via the
GST_PLUGIN_SCANNER env var if that doesn't work.
Update the uninstalled script.
Install the plugin-scanner to the libexec dir
Apparently the sed that ships on Solaris 10 doesn't support character
classes like [:alnum:], so don't use them. We don't need them for the
symbol names that are being extracted anyway.
Also, use $(SED) instead of 'sed'
