Abstract: Embodiments of the disclosure provides a method, apparatus, electronic device and storage medium for video bitrate switching. The method includes: in response to a determination that a condition for video bitrate switching is satisfied, determining a target video bitrate to be switched to; determining, based on a playback time of a delivered audio and video frame, target switching data for switching to a target video stream corresponding to the target video bitrate; and in response to a determination that an audio and video frame to be delivered is consistent with the target switching data, delivering audio and video frames in the target video stream to a client in sequence.

Abstract: A data deduplication method includes: acquiring a live streaming data stream to be processed, wherein the data stream includes at least one audio/video packet; and executing following operations on one audio/video packet, each audio/video packet carrying an identifier, and the identifier being determined according to the order of the audio/video packet in the live streaming data stream; determining, according to the identifier of the audio/video packet, whether the audio/video packet is a repeatedly acquired audio/video packet, and if so, discarding the audio/video packet. Accordingly, it is ensured that no unduplicated data is sent to a user, and the problem that in a live streaming process, due to the fact that an intermediate link is reconnected, a user acquired part of duplicated data, and the audio/video rollback phenomenon caused by the duplicated data being played is solved.
