During the video transmission process, the original picture is generally sent to the background server, and the server encodes the original picture according to the resolution selected by the client (that is, the playback software video player client), and sends the encoded file to the video player client Then the video playback client decompresses and plays it. This is the step of switching resolution during video playback. Since data packets need to be retransmitted, it generally takes several seconds to tens of seconds to complete the resolution switching process, which affects Viewing effect, secondly, during the playback process, if the client needs to perform a partial zoom-in operation during the playback process, since the video playback client is not playing the original picture, the image quality will be reduced after zooming in

Embodiment Construction
[0021] The technical solution of the present invention will be further described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following description.
[0022] refer to figure 1 As shown, a video playback system based on cloud streaming media clipping, the system includes:
[0023] The camera group used to obtain the original picture of the video. The video images captured by the camera group are divided into two outputs, one output is connected to the nonlinear editing module, and the other output is connected to the video switching matrix;
[0024] The nonlinear editing module is connected to the storage server, the storage server is connected to the cloud processing module, and the video signal processed by the cloud processing module is uploaded to the network platform as the first video output link;
[0025] The output end of the video switching matrix is divided into two outputs, one is co...

The present invention relates to a video playback system based on cloud streaming media clipping, including a camera group, one output of the camera group is connected to a nonlinear editing module, and the other output is connected to a video switching matrix; the nonlinear editing module is sequentially connected to a storage server and The cloud processing module is connected as the first video output link; the output end of the video switching matrix is divided into two outputs, one is connected to the slice encoder as the second video output link, and the other is connected to the video conversion matrix and video clipping The array is used as the third video output link; the video playback client of the network platform selects the corresponding video output link according to the user operation, and the present invention adopts the multi-channel conversion module to synchronously encode the original picture into images of different resolutions, and then upload the Complete the picture cutting operation, so that almost zero waiting is achieved during the resolution switching process, and the browsing experience is improved.
Description
technical field [0001] The present invention relates to the field of streaming media playback, in particular to a video playback system based on cloud streaming media clipping. Background technique [0002] Streaming media refers to a media format played on the Internet in a streaming manner. Streaming media is also called streaming media, which means that businesses use a video transmission server to send programs as data packets and transmit them to the network. After the user decompresses the data through the decompression device, the program will be displayed as it was before transmission. In the process of video transmission, the original picture is generally sent to the background server, and the server encodes the original picture according to the resolution selected by the client (that is, the playback software video player client), and sends the encoded file to the video player client Then the video playback client decompresses and plays it. This is the step of sw...
