Claim 14:
15. A non-transitory computer readable storage medium storing computer instructions, wherein, the computer instructions, when executed by a processor, cause the processor to perform operations, the operations comprising:
acquiring a target processing request including a target audio and video data stream, wherein the target processing request records a processing purpose in a preset field in a format that is easy to identify;
determining a target audio and video pipeline corresponding to the target processing request; the audio and video pipeline being constituted based on a plurality of functional components arranged in a chain structure, and the functional components being uniformly dispatched input data and recovered output data by a preset data stream dispatching module;
calling the target audio and video pipeline to continuously process the target audio and video data stream, and continuously outputting a processed audio and video data stream obtained after processing;
controlling the data stream dispatching module to detect a time stamp of received audio and video data; and
in response to determining that new audio and video data is processed prior to old audio and video data based on the time stamp, discarding the unprocessed old audio and video data; wherein the new audio and video data and the old audio and video data correspond to a same generating source, and a generated duration of the new audio and video data is shorter than a generated duration of the old audio and video data.
