Problems solved by technology

In this way, the process of loading 40 frames of video data will seriously affect the efficiency of the entire transcoding
[0004] It can be seen that the transcoding process in the prior art will waste more time in multiple stages, resulting in slower transcoding speed and longer waiting time for users

Embodiment 1

[0019] The present application provides a transcoding method for audio and video streams, and the transcoding method can be applied to a transcoding device or a transcoding process. see figure 2 , the method may include the following steps.

[0020] S1: Acquire an audio and video source stream from the source server, and specify a preset encapsulation format as the encapsulation format of the audio and video source stream when transcoding the audio and video source stream.

[0021] In this embodiment, the source server may be a server that stores an original audio and video stream, and the original audio and video stream may be the above-mentioned audio and video source stream. Before the audio and video source stream needs to be provided to the client for playback, the audio and video source stream can be converted into a format that can be recognized by the client through a transcoding device or a transcoding process.

[0022] In this embodiment, after the audio and video...

Embodiment 2

[0036] see Figure 4 , the present application also provides a transcoding device for audio and video streams, the device comprising:

[0037] An encapsulation format specifying unit, configured to obtain an audio and video source stream from a source server, and specify a preset encapsulation format as the encapsulation format of the audio and video source stream when transcoding the audio and video source stream;

[0038] The decoder initialization unit is used to parse the header file data of the audio and video source stream, obtain the configuration information of the audio and video source stream, and initialize the video decoder and the audio decoder respectively according to the configuration information;

[0039] A re-encoding unit, configured to use the initialized video decoder and audio decoder to decode the audio and video source stream, re-encode the decoded audio and video data into a target audio and video stream, and push the target audio and video stream to ...

Abstract

The invention discloses an audio-video stream transcoding method and equipment. The method comprises the following steps: acquiring audio-video source stream from a source server, and specifying a preset package format as a package format of the audio-video source stream when performing transcoding on the audio-video source stream; analyzing the head file data of the audio-video source stream to obtain configuration information of the audio-video source stream, and respectively initializing a video decoder and an audio decoder according to the configuration information; decoding the audio-video source stream by using the initialized video decoder and the audio decoder, and recoding the decoded audio-video data as the target audio-video stream, and pushing the target audio-video stream to alive server. Through the transcoding method and equipment of the audio-video stream provided by the application, the transcoding speed can be improved.

Description

technical field [0001] The present invention relates to the technical field of audio and video processing, and in particular, to a method and device for transcoding audio and video streams. Background technique [0002] With the continuous development of Internet technology, the dominant content in the Internet has gradually developed from text and pictures to audio and video. Currently, due to the variety of audio and video formats, the formats of audio and video uploaded by different users to the Internet are not uniform. However, the client that plays audio and video may not be able to adapt to all formats of audio and video. Therefore, before providing audio and video to the client, the format of the audio and video is usually converted to a format supported by the client, so that the client can play normally. received audio and video. [0003] see figure 1 , at present, when transcoding audio and video, it usually includes several processes of protocol parsing, strea...
