Frame alignment method, device and device for video stream

Abstract

The invention relates to a video stream frame positioning method and device, and a piece of equipment. The method comprises the steps of receiving video data sent by a distribution server, wherein the video data comprises at least two frames of images; obtaining the image size and data value sum of each frame of image through calculation; judging whether there are repeated images in the video data or not according to the image size and data value sum of each frame of image; and screening the repeated image if there are the repeated images in the video data, and sending the other images in the video data to a decoding module for decoding according to a breakpoint mode. Through comparison of the image size of each frame of image in the received video data with the magnitude of the decoded data, whether there are the repeated frames or not is determined; if there are repeated images, the repeated images are screened and then are sent to the decoding module for decoding; the inaccurate time stamp resulting from the repeated images is avoided; and the data decoding accuracy is ensured.

Description

technical field [0001] The present disclosure relates to computer technology, and in particular to a frame positioning method, device and equipment for video streams. Background technique [0002] With the increasing popularity of the Internet, the data transmitted on the network is no longer limited to text and graphics, but is gradually transitioning to multimedia formats such as audio and video. At present, when transmitting multimedia files such as audio / video on the network, there are basically only two options: downloading and streaming. If streaming audio / video transmission is used, the audio, video, animation and other multimedia files will be sent to the user continuously and in real time by a dedicated streaming media server, so that the user does not have to wait until the entire file is downloaded, but only It takes a few seconds of start-up delay. When the multimedia data is played on the client computer, the rest of the file will continue to be downloaded from...

Problems solved by technology

If streaming audio / video transmission is used, the audio, video, animation and other multimedia files will be sent to the user continuously and in real time by a dedicated streaming media server, so that the user does not have to wait until the entire file is downloaded, but only It takes a few seconds of start-up delay. When the multimedia data is played on the client computer, the rest of the file will continue to be downloaded from the streaming server. In the process of using this method, the image of each frame is pre-loaded The timestamp is set, and the receiving end uses the timestamp to decode, but when the network abnormality or other conditions cause frame repetition and other problems, that is, when the timestamp is incorrect, it is easy to cause internal confusion in the decoder and cause decoding errors
