Zusammenfassung:	The present disclosure relates to systems and methods for synchronizing audio and video. The systems and methods may perform operations including: obtaining a data stream including a sequence of video frames and a sequence of audio samples; inputting the sequence of video frames into a video channel, the sequence of video frames being processed and outputted from the video channel; inputting, for processing, the sequence of audio samples into an audio channel, the audio channel including a data buffer configured to buffer processed audio samples, a volume threshold of the data buffer being determined according to a time for processing one or more successive video frames; determining that a data volume of audio samples buffered in the data buffer exceeds the volume threshold; and in response to a determination that the data volume of buffered audio samples exceeds the volume threshold, outputting the buffered audio samples from the audio channel.
