Abstract

The invention relates to the technical field of live broadcast pushing stream, and particularly relates to a live broadcast data multiplexing method, apparatus and device, and a storage medium. Live broadcast data comprise video data, audio data and lyrics data. The method comprises the following steps: step S1, respectively encoding multiple frames of video data packets, multiple frames of audiodata packets and the multiple frames of lyrics data packets at a preset frame rate; step S2: respectively storing the data packets in a video buffer queue, an audio buffer queue and a lyrics buffer queue according to the sequence of timestamps; and step S3: respectively extracting a first frame of video data packets, a first frame of audio data packets and a first frame of lyrics data packets at the head of the queues from the video buffer queue, the audio buffer queue and the lyrics buffer queue; and step S4: extracting the data packet with the minimum timestamp from the first frame of videodata packets, the first frame of audio data packets and the first frame of lyrics data packets, adding frame header information to the data packet with the minimum timestamp, performing live broadcasttransmission, and skipping to step S3 until all data packets in all queues are transmitted.

Description

technical field [0001] The present invention relates to the technical field of live stream pushing, and in particular to a live data multiplexing method, device, storage medium and equipment. Background technique [0002] With the rapid development of science and technology, more and more electronic multimedia technologies are applied to people's daily life, among which live video broadcasting is one of the emerging applications. The live video broadcast can be broadcast live in the form of video on different communication platforms through the network system at the same time, which is intuitive, fast and interactive. [0003] Currently there is a live video method, that is, the anchor plays the song through the live video, and the lyrics of the song will also be broadcast live to the audience simultaneously. For how to synchronously broadcast the lyrics to the audience, the existing technology adopts the method of superimposing the lyrics in the video stream and encoding t...
