Embodiment 1

[0153] A video decoding design scheme based on fault-tolerant mechanism, (1) create a network receiving task to block receiving image data, and use a ring buffer to synchronize multi-channel image data; (2) establish a mechanism for filtering error frames for multi-channel image data, according to (2 ) analyzing the encoding rule and the h265 frame protocol, and filtering error frames for the video stream; (3) establishing a fault-tolerant mechanism, according to (3) analyzing the frame type in the encoding rule and recording and saving it as an analysis basis, and dynamically adjusting the reference frame of each image; ( 4) Monitor the decoding module in real time, and restore the decoding error state through soft restart.

[0154] Further, the above (1)(2) provides a cache mechanism and an error frame mechanism for the processing of multi-channel video.

[0155] Further, (3) by analyzing the error frame type, dynamically record the type of the protocol frame in the image fr...

Abstract

The invention relates to a multi-channel video decoding method based on a fault-tolerant mechanism, and belongs to the field of video encoding and decoding. The method comprises the following steps: firstly, configuring a network receiving thread, and synchronizing each path of image data through a buffer area mechanism; secondly, analyzing original image data and a coding rule, and performing error frame filtering on received data; then, adopting a fault-tolerant mechanism to carry out reference frame adjustment on the image data frame sequence; and finally, starting a sending task of the video stream, monitoring the state of a decoding channel in real time, resetting parameters through soft restart of the decoding module, applying error image data to the decoding module, and dynamically controlling a video stream output task according to a decoding requirement.
