Problems solved by technology

[0004] However, the HLS segment files generated by HLS are usually large, and when they are used for subsequent applications such as network transmission (such as live broadcast or recording), problems such as transmission interruption (such as the phenomenon of stuttering experienced by users) are prone to occur. ), especially when the network bandwidth is unstable, it is difficult to achieve a stable transmission effect
[0005] It can be seen from this that existing multimedia data transmission technologies such as HLS described in the above example, because the multimedia data files generated by them are large, it is easy to cause problems such as transmission interruption, and it is difficult to achieve stable transmission effects, which is not conducive to such as network transmission. Waiting for follow-up application

Abstract

The invention provides a device, a method and an electronic device for generating media data, so as to overcome the problem of unstable transmission caused by large generated multimedia data files in the existing multimedia data transmission technology. The above-mentioned equipment includes: an audio recording unit, recording one or more times from the first predetermined time, for each recording, when the first predetermined condition is met, the audio data at the media source is recorded and an audio file is generated, and when the second predetermined condition is met, the audio file is generated. When the predetermined condition stops the current recording and stores the audio file; the image capture unit, from the first predetermined time, captures the video image of the media source at predetermined time intervals and stores it as an image file; and the generation unit generates an index file, together with all The audio file and the image file together serve as media data for the server, and the index file includes index information and time stamps of each audio file and each image file. The above technology of the present invention can be applied to the field of multimedia data transmission.

Description

technical field [0001] The invention relates to the field of multimedia data transmission, in particular to a device, method and electronic device for generating media data. Background technique [0002] With the advancement of science and technology, people's lives are increasingly inseparable from computers and network technology. At present, in the field of computer and network technology, there are many multimedia data transmission technologies. Application developers can usually choose different multimedia data transmission technologies according to different application scenarios. [0003] For example, the existing HLS (HTTP Live Streaming) is a streaming media transmission protocol based on HTTP, which can realize live streaming and on-demand streaming media through network data transmission. According to the HLS protocol, the media data is a bunch of fragmented files, including m3u(8) index files, TS media fragmented files and key encrypted string files, etc., and ...
