From Pad

newFromStaticTemplate gst.pad.Pad newFromStaticTemplate(gst.static_pad_template.StaticPadTemplate templ, string name): Creates a new pad with the given name from the given static template. If name is null, a guaranteed unique name (across all pads) will be assigned. This function makes a copy of the name so you can safely free the name.
newFromTemplate gst.pad.Pad newFromTemplate(gst.pad_template.PadTemplate templ, string name): Creates a new pad with the given name from the given template. If name is null, a guaranteed unique name (across all pads) will be assigned. This function makes a copy of the name so you can safely free the name.
linkGetName string linkGetName(gst.types.PadLinkReturn ret): Gets a string representing the given pad-link return.
activateMode bool activateMode(gst.types.PadMode mode, bool active): Activates or deactivates the given pad in mode via dispatching to the pad's activatemodefunc. For use from within pad activation functions only.
addProbe gulong addProbe(gst.types.PadProbeType mask, gst.types.PadProbeCallback callback): Be notified of different states of pads. The provided callback is called for every state that matches mask.
canLink bool canLink(gst.pad.Pad sinkpad): Checks if the source pad and the sink pad are compatible so they can be linked.
chain gst.types.FlowReturn chain(gst.buffer.Buffer buffer): Chain a buffer to pad.
chainList gst.types.FlowReturn chainList(gst.buffer_list.BufferList list): Chain a bufferlist to pad.
checkReconfigure bool checkReconfigure(): Check and clear the #GST_PAD_FLAG_NEED_RECONFIGURE flag on pad and return true if the flag was set.
createStreamId string createStreamId(gst.element.Element parent, string streamId): Creates a stream-id for the source #GstPad pad by combining the upstream information with the optional stream_id of the stream of pad. pad must have a parent #GstElement and which must have zero or one sinkpad. stream_id can only be null if the parent element of pad has only a single source pad.
eventDefault bool eventDefault(gst.object.ObjectGst parent, gst.event.Event event): Invokes the default event handler for the given pad.

getCurrentCaps gst.caps.Caps getCurrentCaps(): Gets the capabilities currently configured on pad with the last #GST_EVENT_CAPS event.

iterateInternalLinksDefault gst.iterator.Iterator iterateInternalLinksDefault(gst.object.ObjectGst parent): Iterate the list of pads to which the given pad is linked to inside of the parent element. This is the default handler, and thus returns an iterator of all of the pads inside the parent element with opposite direction.

linkFull gst.types.PadLinkReturn linkFull(gst.pad.Pad sinkpad, gst.types.PadLinkCheck flags): Links the source pad and the sink pad.

linkMaybeGhostingFull bool linkMaybeGhostingFull(gst.pad.Pad sink, gst.types.PadLinkCheck flags): Links src to sink, creating any #GstGhostPad's in between as necessary.
markReconfigure void markReconfigure(): Mark a pad for needing reconfiguration. The next call to gst.pad.Pad.checkReconfigure will return true after this call.
needsReconfigure bool needsReconfigure(): Check the #GST_PAD_FLAG_NEED_RECONFIGURE flag on pad and return true if the flag was set.

peerQuery bool peerQuery(gst.query.Query query): Performs gst.pad.Pad.query on the peer of pad.
peerQueryAcceptCaps bool peerQueryAcceptCaps(gst.caps.Caps caps): Check if the peer of pad accepts caps. If pad has no peer, this function returns true.
peerQueryCaps gst.caps.Caps peerQueryCaps(gst.caps.Caps filter): Gets the capabilities of the peer connected to this pad. Similar to gst.pad.Pad.queryCaps.
peerQueryConvert bool peerQueryConvert(gst.types.Format srcFormat, long srcVal, gst.types.Format destFormat, long destVal): Queries the peer pad of a given sink pad to convert src_val in src_format to dest_format.

pushList gst.types.FlowReturn pushList(gst.buffer_list.BufferList list): Pushes a buffer list to the peer of pad.
query bool query(gst.query.Query query): Dispatches a query to a pad. The query should have been allocated by the caller via one of the type-specific allocation functions. The element that the pad belongs to is responsible for filling the query with an appropriate response, which should then be parsed with a type-specific query parsing function.
queryAcceptCaps bool queryAcceptCaps(gst.caps.Caps caps): Check if the given pad accepts the caps.
queryCaps gst.caps.Caps queryCaps(gst.caps.Caps filter): 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.Event.newCaps - use gst.pad.Pad.getCurrentCaps 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 null, otherwise ANY.

queryDefault bool queryDefault(gst.object.ObjectGst parent, gst.query.Query query): Invokes the default query handler for the given pad. The query is sent to all pads internally linked to pad. Note that if there are many possible sink pads that are internally linked to pad, only one will be sent the query. Multi-sinkpad elements should implement custom query handlers.
queryDuration bool queryDuration(gst.types.Format format, long duration): Queries a pad for the total stream duration.
queryPosition bool queryPosition(gst.types.Format format, long cur): Queries a pad for the stream position.
removeProbe void removeProbe(gulong id): Remove the probe with id from pad.
sendEvent bool sendEvent(gst.event.Event event): Sends the event to the pad. This function can be used by applications to send events in the pipeline.

setOffset void setOffset(long offset): Set the offset that will be applied to the running time of pad.
startTask bool startTask(gst.types.TaskFunction func): Starts a task that repeatedly calls func with user_data. This function is mostly used in pad activation functions to start the dataflow. The #GST_PAD_STREAM_LOCK of pad will automatically be acquired before func is called.
stickyEventsForeach void stickyEventsForeach(gst.types.PadStickyEventsForeachFunction foreachFunc): Iterates all sticky events on pad and calls foreach_func for every event. If foreach_func returns false the iteration is immediately stopped.
stopTask bool stopTask(): Stop the task of pad. This function will also make sure that the function executed by the task will effectively stop if not called from the GstTaskFunction.
storeStickyEvent gst.types.FlowReturn storeStickyEvent(gst.event.Event event): Store the sticky event on pad
unlink bool unlink(gst.pad.Pad sinkpad): Unlinks the source pad from the sink pad. Will emit the #GstPad::unlinked signal on both pads.
