Abstract

The invention discloses an H264 video data processing method and system based on a mobile terminal. According to the method and the system, the H264 video data can be stably played and displayed at the Andriod mobile terminal. Specifically, the method comprises that: an Andriod end receives H264 video data packets coming from a video collection end; unpacking and framing operation is carried out to the H264 video data packets so as to obtain the framed video data; the framed video data is stored in a shared memory; a bottom layer decoding end interacts the data in the decoding process of the framed video data with the Andriod end through the shared memory so as to obtain the decoded video data; the Andriod end extracts the decoded video data from the shared memory. Visibly, according to the invention, the memory space of the mobile terminal is fully utilized; and the problems in the prior art that copy operation and conversion operation are frequent, therefore decoding is not in time, and further the data interaction is blocked are effectively solved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a video data processing method and system based on a mobile terminal. Background technique [0002] Nowadays, with the popularization of 4G network and the wide application of video surveillance in personal, property and intelligent buildings, people pay more and more attention to remote video surveillance based on mobile terminals. [0003] In practical applications, mobile terminals with video surveillance functions mainly obtain video data collected by the camera through the communication network, and then display the video data after unpacking, framing, decoding, and rendering. [0004] However, in the process of processing video data by Android mobile terminals, there are the following problems: in the process of decoding the video data after framing, the Android end (i.e. SDK layer) and the underlying decoding end (i.e. NDK layer) are required Perform frequent data...
