Video monitoring method based on H.264 coding technology

Abstract

Disclosed is a video monitoring method based on an H.264 coding technology. In the method, a circuit structure of a video monitoring server includes a data acquiring circuit, a data coding circuit and a data transmission circuit; and a circuit structure of a monitoring client includes a data receiving circuit and a data decoding / displaying circuit. Output / input ends of the above-mentioned circuits are connected sequentially in an end-to-tail way. The above-mentioned circuits all adopt multi-thread input / output control. The data coding circuit and the data decoding / displaying circuit all adopt an H.264 coding / decoding mechanism. The video monitoring method has the characteristics of fluent and highly real-time videos; different threads are adopted in data acquiring and coding so that data acquiring and coding can be carried out simultaneously; and at the same time, queues with buffers are adopted so that video acquiring rate and coding rate are greatly improved. Therefore, fluency and real-time performance of the videos are ensured. At the same time, a multi-thread framework is also adopted by the monitoring client so that data receiving and data decoding can be carried out simultaneously. Therefore, real-time performance of the system is further improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video monitoring method based on H.264 encoding technology which improves real-time performance and fluency of video transmission. Background technique [0002] With the development of computer, image acquisition, image coding and other technologies, video surveillance is widely used in security, automation control and other fields. [0003] H.264 is a brand-new digital video coding standard. It has high coding efficiency, strong network adaptability of code stream structure, increased error recovery capability, and can well adapt to the application of IP and wireless networks. In the current monitoring system, the video acquisition rate is often lower than 25 frames per second, which cannot meet the smoothness requirements of video playback, and will also bring hidden dangers to areas with high security requirements; at the same time, monitoring The real-time perform...
