Method for transmitting streaming media data

Abstract

The invention discloses a method for transmitting streaming media data, and belongs to the technical field of image communication. The method comprises: a step S1 of taking a current write-in positionof the streaming media data as a transmitting position where a transmitting operation is performed; a step S2 of comparing the transmitting position with the write-in position: if the write-in position is greater than the transmitting position and the distance between the transmitting position and the write-in position is less than or equal to a preset length of a sliding window, performing the transmitting operation; and otherwise, stopping the transmitting operation. The technical scheme of the method has the beneficial effects that: a plurality of independent buffer areas are set, a Q value of the transmitting position is calculated before transmission, and whether to perform the transmitting operation is directly judged according to the Q value, thereby improving response speed and reducing consumption of system resources.

Description

technical field [0001] The invention relates to a technology in the field of image communication, in particular to a streaming media data sending method. Background technique [0002] Network cameras are special equipment for collecting external data and are an important part of the current security field. While capturing images, it also provides the function of network transmission, so how to organize, store and forward streaming media data has become a problem that must be faced. What this service needs to solve is an obvious producer-consumer problem. The producer of streaming media data is responsible for writing the generated data into the buffer, and the network sending module, as the consumer of media data, is responsible for taking and sending the data. , but the unequal speed and status between production and consumption aggravate the complexity of problem handling. [0003] In the production and consumption model of code stream, the following processing methods a...

Problems solved by technology

The "control information block" is the medium of communication between multiple producers and multiple consumers. Usually, the synchronization method of process and thread is used to solve the access problem. Commonly used methods include mutex and semaphore, etc. If the solution is not enough Perfect, it is easy to waste computing resources or even deadlock
