A default error function that uses g_printerr() to display the error message
and the optional debug string.. Read more
Gets the corresponding ControlBinding for the property. This should be
unreferenced again after use. Read more
Obtain the control-rate for this self. Audio processing Element
objects will use this rate to sub-divide their processing loop and call
sync_values() in between. The length of the processing segment
should be up to control-rate nanoseconds. Read more
Returns the parent of self. This function increases the refcount
of the parent object so you should gst_object_unref() it after usage. Read more

the object hierarchy. Only useful (or used) for debugging. Read more

Activates or deactivates the given pad in mode via dispatching to the
pad’s activatemodefunc. For use from within pad activation functions only. Read more
Checks if the source pad and the sink pad are compatible so they can be linked. Read more
Check and clear the PadFlags::NEED_RECONFIGURE flag on self and return true
if the flag was set. Read more
Creates a stream-id for the source Pad self by combining the
upstream information with the optional stream_id of the stream
of self. self must have a parent Element and which must have zero
or one sinkpad. stream_id can only be None if the parent element
of self has only a single source pad. Read more
Calls forward for all internally linked pads of self. This function deals with
dynamically changing internal pads and will make sure that the forward
function is only called once for each pad. Read more
Gets the capabilities of the allowed media types that can flow through
self and its peer. Read more
Gets the capabilities currently configured on self with the last
EventType::Caps event. Read more
Gets the direction of the pad. The direction of the pad is decided at construction time so this function does not take the LOCK. Read more
Gets the FlowReturn return from the last data passed by this pad.
Get the offset applied to the running time of self. self has to be a source
pad. Read more
Gets the template for self. Read more
Gets the capabilities for self’s template. Read more
Gets the peer of self. This function refs the peer pad so
you need to unref it after use. Read more
v1_18 only.If there is a single internal link of the given pad, this function will return it. Otherwise, it will return NULL. Read more
Returns a new reference of the sticky event of type event_type
from the event. Read more
v1_10 only.v1_12 only.Get self task state. If no task is currently
set, TaskState::Stopped is returned. Read more
Check if self has caps set on it with a EventType::Caps event. Read more
Checks if the pad is blocked or not. This function returns the
last requested state of the pad. It is not certain that the pad
is actually blocking at this point (see is_blocking()). Read more
Links the source pad and the sink pad. Read more

pub fn link_maybe_ghosting_full<P>(

) -> Result<(), BoolError> where
P: IsA<Pad>, [src]v1_10 only.Mark a pad for needing reconfiguration. The next call to
check_reconfigure() will return true after this call. Read more
Check the PadFlags::NEED_RECONFIGURE flag on self and return true
if the flag was set. Read more
Pause the task of self. This function will also wait until the
function executed by the task is finished if this function is not
called from the task function. Read more
Gets the capabilities of the peer connected to this pad. Similar to
query_caps(). Read more
Check if the given pad accepts the caps. Read more
Gets the capabilities this pad can produce or consume.
Note that this method doesn’t necessarily return the caps set by sending a
gst_event_new_caps() - use current_caps() for that instead.
gst_pad_query_caps returns all possible caps a pad can operate with, using
the pad’s CAPS query function, If the query fails, this function will return
filter, if not None, otherwise ANY. Read more
Activates or deactivates the given pad. Normally called from within core state change functions. Read more
Set the offset that will be applied to the running time of self. Read more
Stop the task of self. This function will also make sure that the
function executed by the task will effectively stop if not called
from the GstTaskFunction. Read more
Store the sticky event on self Read more
Unlinks the source pad from the sink pad. Will emit the signal::Pad::unlinked
signal on both pads. Read more
A helper function you can use that sets the FIXED_CAPS flag This way the default CAPS query will always return the negotiated caps or in case the pad is not negotiated, the padtemplate caps. Read more
