The present disclosure belongs to the technical field of
video quality evaluation, and particularly relates to a
video quality evaluation method,
system, device and medium based on multi-
modal parallel analysis, which comprises the following steps: receiving a course video to be audited, loading user preset audit parameter configuration; unpacking the course video to be audited to obtain an initial video coding
stream and an initial audio coding
stream, simultaneously performing audio track integrity checking, terminating the audio analysis process based on the checking result, only performing video analysis, or simultaneously performing video and audio analysis audit processes; pre-
processing the initial video coding
stream and the initial audio coding stream; based on an asynchronous parallel architecture, performing multiple audit tasks on the standard
image frame sequence and the standard audio data in parallel to obtain multiple output results; converging the multiple output results, performing cross-
modal space-
time alignment and fusion deduplication
processing to obtain a
processing result; and generating a structured audit report according to the processing result. The present application improves the efficiency and accuracy of
video quality evaluation.
