aliasTypeFindData = GstTypeFindData *

aliasCollectDataDestroyNotify = void delegate(gstbase.collect_data.CollectData data)

A function that will be called when the #GstCollectData will be freed. It is passed the pointer to the structure and should free any custom memory and resources allocated for it.

Parameters

data the #GstCollectData that will be freed

aliasCollectPadsBufferFunction = gst.types.FlowReturn delegate(gstbase.collect_pads.CollectPads pads, gstbase.collect_data.CollectData data, gst.buffer.Buffer buffer)

A function that will be called when a (considered oldest) buffer can be muxed. If all pads have reached EOS, this function is called with null buffer and null data.

Parameters

`pads`	the #GstCollectPads that triggered the callback
`data`	the #GstCollectData of pad that has received the buffer
`buffer`	the #GstBuffer

Returns

[gst.types.FlowReturn.Ok] for success

aliasCollectPadsClipFunction = gst.types.FlowReturn delegate(gstbase.collect_pads.CollectPads pads, gstbase.collect_data.CollectData data, gst.buffer.Buffer inbuffer, out gst.buffer.Buffer outbuffer)

A function that will be called when inbuffer is received on the pad managed by data in the collectpad object pads.

The function should use the segment of data and the negotiated media type on the pad to perform clipping of inbuffer.

This function takes ownership of inbuffer and should output a buffer in outbuffer or return null in outbuffer if the buffer should be dropped.

Parameters

`pads`	a #GstCollectPads
`data`	a #GstCollectData
`inbuffer`	the input #GstBuffer
`outbuffer`	the output #GstBuffer

Returns

a #GstFlowReturn that corresponds to the result of clipping.

aliasCollectPadsCompareFunction = int delegate(gstbase.collect_pads.CollectPads pads, gstbase.collect_data.CollectData data1, gst.types.ClockTime timestamp1, gstbase.collect_data.CollectData data2, gst.types.ClockTime timestamp2)

A function for comparing two timestamps of buffers or newsegments collected on one pad.

Parameters

`pads`	the #GstCollectPads that is comparing the timestamps
`data1`	the first #GstCollectData
`timestamp1`	the first timestamp
`data2`	the second #GstCollectData
`timestamp2`	the second timestamp

Returns

Integer less than zero when first timestamp is deemed older than the second one.

Zero if the timestamps are deemed equally old. Integer greater than zero when second timestamp is deemed older than the first one.

aliasCollectPadsEventFunction = bool delegate(gstbase.collect_pads.CollectPads pads, gstbase.collect_data.CollectData pad, gst.event.Event event)

A function that will be called while processing an event. It takes ownership of the event and is responsible for chaining up (to [gstbase.collect_pads.CollectPads.eventDefault]) or dropping events (such typical cases being handled by the default handler).

Parameters

`pads`	the #GstCollectPads that triggered the callback
`pad`	the #GstPad that received an event
`event`	the #GstEvent received

Returns

true if the pad could handle the event

aliasCollectPadsFlushFunction = void delegate(gstbase.collect_pads.CollectPads pads)

A function that will be called while processing a flushing seek event.

The function should flush any internal state of the element and the state of all the pads. It should clear only the state not directly managed by the pads object. It is therefore not necessary to call gst_collect_pads_set_flushing nor gst_collect_pads_clear from this function.

Parameters

pads a #GstCollectPads

aliasCollectPadsFunction = gst.types.FlowReturn delegate(gstbase.collect_pads.CollectPads pads)

A function that will be called when all pads have received data.

Parameters

pads the #GstCollectPads that triggered the callback

Returns

[gst.types.FlowReturn.Ok] for success

aliasCollectPadsQueryFunction = bool delegate(gstbase.collect_pads.CollectPads pads, gstbase.collect_data.CollectData pad, gst.query.Query query)

A function that will be called while processing a query. It takes ownership of the query and is responsible for chaining up (to events downstream (with [gst.pad.Pad.eventDefault]).

Parameters

`pads`	the #GstCollectPads that triggered the callback
`pad`	the #GstPad that received an event
`query`	the #GstEvent received

Returns

true if the pad could handle the event

aliasDataQueueEmptyCallback = void delegate(gstbase.data_queue.DataQueue queue)

aliasDataQueueFullCallback = void delegate(gstbase.data_queue.DataQueue queue)

aliasTypeFindHelperGetRangeFunction = gst.types.FlowReturn delegate(gst.object.ObjectWrap obj, gst.object.ObjectWrap parent, ulong offset, uint length, out gst.buffer.Buffer buffer)

This function will be called by [gstbase.global.typeFindHelperGetRange] when typefinding functions request to peek at the data of a stream at certain offsets. If this function returns GST_FLOW_OK, the result buffer will be stored in buffer. The contents of buffer is invalid for any other return value.

This function is supposed to behave exactly like a #GstPadGetRangeFunction.

Parameters

`obj`	a #GstObject that will handle the getrange request
`parent`	the parent of obj or null
`offset`	the offset of the range
`length`	the length of the range
`buffer`	a memory location to hold the result buffer

Returns

GST_FLOW_OK for success
