queue

Function	Native GStreamer plugin. When this plugin outputs data, another thread is created for subsequent processing to decouple the input data from the output data, create a buffer queue, and store the data that has not been output to the downstream plugin.
Constraints	By default, the buffer queue can store fewer than 200 buffers whose size is smaller than 10 MB. The storage duration is 1 second.
Plugin Base Class (Factory)	queue
Input/Output	Input: buffer and metadata Output: buffer and metadata
Property	For details, see Table 1.
