Embodiment Construction
[0036] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0037] Such as figure 1 As shown, the application includes two ends, respectively CDN end 1 and live video format conversion server 2 end, wherein, CDN (Content Delivery Network) end 1 is used to receive the original live video flow from the streaming client, and is used to A file in a preset format after the format conversion of the media file is received from the live video format conversion server. The live video format conversion server 2 is used to receive media files from the CDN, convert the media files, and send the converted files to the CDN for storage.
[0038] Specifically, CDN is a content distribution network. It is a layer of intelligent virtual network based on the existing Internet form...

The application provides a storage method and device for a live video. A live video format conversion server receives a download address of live video streaming from a CDN end, sends a video download request including the download address to the CDN end, receives a media file corresponding to the video download request from the CDN end, converts the received media file into a file in a preset format and sends the file in the preset format to the CDN end for storage; the live video streaming before format conversion is stored at the CDN end, and thus, guarantee in the aspect of a network bandwidth of a CDN is obtained, the live video format conversion server can acquire the complete media file before format conversion from the CDN end for format conversion, and the problem of live video streaming missing caused by limitation to the network bandwidth of a server set up by the self in the prior art cannot exist; and in addition, the file in the preset format after format conversion is also stored at the CDN end, so that the complete video steaming can be guaranteed to be played.
Description
technical field [0001] The present application relates to a method and device for saving live video. Background technique [0002] The preservation of the current live video is to save the audio and video data in the media stream of the live protocol such as rtmp (Real Time Media Protocol), hls (HTTP LiveStreaming) and rtp (Real-Time Transport Protocol) as a file of the corresponding local format. Considering the compatibility of various playback devices, the media file format of mp4 (MPEG-4 Part14) is generally adopted. The traditional way of saving files is to push the media stream to the server built by oneself during the live broadcast. After the live broadcast ends, the data collected on the server is converted into mp4 files using common third-party tools (such as ffmpeg). However, due to the impact of network bandwidth, the data collected by the server is often missing, and the third-party tools are not good enough to deal with the audio and video out-of-sync problem...
