Abstract

The invention discloses a video frame data packaging method, an intelligent terminal and a storage device. The packaging method comprises the steps that a real-time video code stream of video frame data is received, when a recording instruction is received, first video frame data between a previous nearest I frame and a current video frame are stored in a set cache region, and the nearest I frameis a starting frame of the first video frame data; a second video frame data after the current video frame is recorded; and the first video frame data and the second video frame data are packaged according to a set protocol. Through the mode, the real-time video code stream of the video frame data can be cached, so that the integrity of real-time video frame data encapsulation is ensured, and therecording of potential important data is ensured.

Description

technical field [0001] The present application relates to the technical field of data encapsulation, and in particular to a video frame data encapsulation method, an intelligent terminal and a storage device. Background technique [0002] In a real-time video stream scenario, in order to ensure real-time data, old data (video frames before the current time point) are usually not retained. And when it is necessary to use the Mp4 (full name MPEG-4 Part 14, which is a multimedia computer file format using MPEG-4) protocol encapsulation of the real-time stream, it will generally start from the current frame of the real-time stream and wait until the nearest I frame arrives. , before recording and encapsulating data. [0003] And because the current complete GOP (Group of Pictures, group of pictures) data is not cached, it will be easy to miss the I frame (intra picture, internal picture) in the GOP, and the I frame is usually the first frame of each GOP. It can be used as a re...
