Problems solved by technology

In the process of compressing the stream, if a larger key frame interval is used, a smaller stream file can be obtained, which is conducive to the upload of the stream file. However, due to the large key frame interval, it is not conducive to dragging the file. It can also cause problems such as long loading times
Conversely, if a smaller keyframe interval is used for compression, although it is beneficial to drag and load files, it is not conducive to uploading the stream file due to the large size of the stream file
[0003] There is no effective solution to this situation in the existing technology, so that the effect of convenient uploading and smooth live broadcast cannot be achieved at the same time

Embodiment Construction

[0020] The principle and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are given only to enable those skilled in the art to better understand and implement the present invention, rather than to limit the scope of the present invention in any way.

[0021] figure 1 is a flow chart showing the stream compression method 100 for live broadcast according to the first embodiment of the present invention. It should be understood that the various steps recorded in the method 100 may be executed in different orders, and / or executed in parallel. The method 100 may also include additional steps and / or omit performing the illustrated steps. The scope of the invention is not limited in this respect.

[0022] After the method 100 starts, at step S102, the first compression is performed on the stream to be broadcasted to obtain the first compressed stream. The "stream to be broadcast...

Abstract

The invention relates to a stream compression method and device for live. The method comprises the following steps: performing the first compression on a to-be-lived stream to acquire a first compressed stream; uploading the first compressed stream; performing the second compression on the first compressed stream to acquire a second compress stream. According to the execution mode of the method, a relatively distinct and smooth video can be lived under relatively less uplink bandwidth.

Description

technical field [0001] Embodiments of the present invention generally relate to the live broadcast field, and more specifically, relate to a stream compression method and device for live broadcast. Background technique [0002] With the continuous development of network and computer technology, live broadcast applications are becoming more and more popular. A live broadcast process often includes a series of processes such as collecting streaming signals, compressing them, and uploading them to the server. In the process of compressing the stream, if a larger key frame interval is used, a smaller stream file can be obtained, which is conducive to the upload of the stream file. However, due to the large key frame interval, it is not conducive to dragging the file. It can also cause problems such as longer loading times. Conversely, if a smaller key frame interval is used for compression, although it is beneficial to dragging and loading files, it is not conducive to uploadi...
