Aliases

GstCollectDataDestroyNotify alias GstCollectDataDestroyNotify = void function(GstCollectData* 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.
GstCollectPadsBufferFunction alias GstCollectPadsBufferFunction = GstFlowReturn function(GstCollectPads* pads, GstCollectData* data, GstBuffer* buffer, void* userData): 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.
GstCollectPadsClipFunction
alias GstCollectPadsClipFunction = GstFlowReturn function(GstCollectPads* pads, GstCollectData* data, GstBuffer* inbuffer, GstBuffer** outbuffer, void* userData): A function that will be called when inbuffer is received on the pad managed by data in the collectpad object pads.
GstCollectPadsCompareFunction alias GstCollectPadsCompareFunction = int function(GstCollectPads* pads, GstCollectData* data1, GstClockTime timestamp1, GstCollectData* data2, GstClockTime timestamp2, void* userData): A function for comparing two timestamps of buffers or newsegments collected on one pad.
GstCollectPadsEventFunction alias GstCollectPadsEventFunction = int function(GstCollectPads* pads, GstCollectData* pad, GstEvent* event, void* userData): A function that will be called while processing an event. It takes ownership of the event and is responsible for chaining up (to CollectPads.eventDefault) or dropping events (such typical cases being handled by the default handler).
GstCollectPadsFlushFunction alias GstCollectPadsFlushFunction = void function(GstCollectPads* pads, void* userData): A function that will be called while processing a flushing seek event.
GstCollectPadsFunction alias GstCollectPadsFunction = GstFlowReturn function(GstCollectPads* pads, void* userData): A function that will be called when all pads have received data.
GstCollectPadsQueryFunction alias GstCollectPadsQueryFunction = int function(GstCollectPads* pads, GstCollectData* pad, GstQuery* query, void* userData): 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 Pad.eventDefault).
GstDataQueueCheckFullFunction alias GstDataQueueCheckFullFunction = int function(GstDataQueue* queue, uint visible, uint bytes, ulong time, void* checkdata): The prototype of the function used to inform the queue that it should be considered as full.
GstDataQueueEmptyCallback alias GstDataQueueEmptyCallback = void function(GstDataQueue* queue, void* checkdata)
GstDataQueueFullCallback alias GstDataQueueFullCallback = void function(GstDataQueue* queue, void* checkdata)
GstTypeFindHelperGetRangeFunction
alias GstTypeFindHelperGetRangeFunction = GstFlowReturn function(GstObject* obj, GstObject* parent, ulong offset, uint length, GstBuffer** buffer): This function will be called by TypeFind.helperGetRange 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.

Enums

GstBaseParseFrameFlags enum GstBaseParseFrameFlags: Flags to be used in a gst.BaseParseFrame.BaseParseFrame
GstBaseSrcFlags enum GstBaseSrcFlags: The gstreamer.Element flags that a basesrc element may have.

Manifest constants

BASE_TRANSFORM_SINK_NAME enum BASE_TRANSFORM_SINK_NAME;: The name of the templates for the sink pad.
BASE_TRANSFORM_SRC_NAME enum BASE_TRANSFORM_SRC_NAME;: The name of the templates for the source pad.

Structs

GstAggregator struct GstAggregator: Undocumented in source.
GstAggregatorClass struct GstAggregatorClass: The aggregator base class will handle in a thread-safe way all manners of concurrent flushes, seeks, pad additions and removals, leaving to the subclass the responsibility of clipping buffers, and aggregating buffers in the way the implementor sees fit.
GstAggregatorPad struct GstAggregatorPad: Undocumented in source.
GstAggregatorPadClass struct GstAggregatorPadClass: Undocumented in source.
GstBaseParse struct GstBaseParse: Undocumented in source.
GstBaseParseClass struct GstBaseParseClass: Subclasses can override any of the available virtual methods or not, as needed. At minimum handle_frame needs to be overridden.
GstBaseParseFrame struct GstBaseParseFrame: Undocumented in source.
GstBaseSinkClass struct GstBaseSinkClass: Subclasses can override any of the available virtual methods or not, as needed. At the minimum, the render method should be overridden to output/present buffers.
GstBaseSrcClass struct GstBaseSrcClass: Subclasses can override any of the available virtual methods or not, as needed. At the minimum, the create method should be overridden to produce buffers.
GstBaseTransformClass struct GstBaseTransformClass: Subclasses can override any of the available virtual methods or not, as needed. At minimum either transform or transform_ip need to be overridden. If the element can overwrite the input data with the results (data is of the same type and quantity) it should provide transform_ip.
GstBitReader struct GstBitReader: Undocumented in source.
GstBitWriter struct GstBitWriter: Undocumented in source.
GstByteReader struct GstByteReader: Undocumented in source.
GstByteWriter struct GstByteWriter: Undocumented in source.
GstCollectData struct GstCollectData: Structure used by the collect_pads.
GstCollectPads struct GstCollectPads: Undocumented in source.
GstDataQueue struct GstDataQueue: Undocumented in source.
GstDataQueueClass struct GstDataQueueClass: Undocumented in source.
GstDataQueueItem struct GstDataQueueItem: Structure used by gst.DataQueue.DataQueue You can supply a different structure, as long as the top of the structure is identical to this structure.
GstDataQueueSize struct GstDataQueueSize: Structure describing the size of a queue.
GstPushSrcClass struct GstPushSrcClass: Subclasses can override any of the available virtual methods or not, as needed. At the minimum, the fill method should be overridden to produce buffers.
