Problems solved by technology

On the one hand, timeliness needs to be considered, and the program needs to be cataloged before it can be sent back to the editing center; on the other hand, the complete transmission of a large number of live videos requires a lot of network traffic and requires a lot of storage space to store

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] Such as figure 1 As shown, a method for editing live video with high time-efficiency based on proxy streaming, the steps are as follows:

[0018] 1. The source of on-site shooting is connected to the transcoding server through SDI signal and the source of high-definition satellite stream through UDP signal transmission;

[0019] 2. Perform real-time transcoding of one input and two outputs of the live broadcast source, and a video stream whose output parameter is a low bit rate is called a proxy stream, and the http stream address is published through the http server that comes with the transcoder. Here we will This stream is marked as stream A; the other stream is recorded and stored in the storage space of the server through transparent transmission or high-quality and high-bit-rate transcoding parameters, and here we mark this stream as stream B;

[0020] 3. Th...

Abstract

The invention discloses a scheme based on an agent flow, and provides a method which can preview a live video in a low time delay state and edit a live video with high timeliness. The technical scheme can effectively improve timeliness, does not need to wait for closure of whole live broadcast, can edit and issue videos earlier, and reduce intermediate network transmission quantity and a lot of storage space, and only needs to finally return and keep required videos after transcoding editing.

Description

technical field [0001] The invention relates to a method for editing live video, in particular to a method for editing live stream with high time efficiency by using proxy stream transmission. Background technique [0002] Currently in the field of multimedia, such as figure 2 As shown, the content of the live video needs to be completely recorded, and then the recorded video is transmitted to the storage of the video editing department through the network, and then the video is split, mosaiced, and subtitled, etc. edit operation. In this process, the video needs to be transmitted to the editing center through the network before editing can be completed. On the one hand, timeliness needs to be considered, and the program needs to be cataloged before it can be sent back to the editing center; on the other hand, the complete transmission of a large number of live videos requires a lot of network traffic and requires a lot of storage space for storage. Contents of the inven...
