Problems solved by technology
For strategy 2, since the data replication speed is generally several orders of magnitude higher than the source data generation speed, there will be basically no data loss caused by insufficient source buffers, but the copying and repeated storage of data will reduce the distribution efficiency
[0005] Therefore, the existing technology has the disadvantages of low distribution efficiency, large resource occupation, and abnormality of one target flow that affects other target flows

Embodiment Construction
[0107] The specific method proposed according to the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0108] The general idea of the present invention is that streaming media distribution method:
[0109] Fragmentation of stream data, better video stream is divided into one piece per frame, audio stream uses data of corresponding time length as one piece; stream data after fragmentation has a corresponding slice information, including the stream type of the slice, whether it is critical Frame, read lock count (currently locked and unused count, initialized to 0), read remaining count (currently need to be used but not yet used count, initialized to the number of target streams) ; Fragmented stream data and corresponding slice information form a stream slice;
[0110] The object that generates the stream is called the source stream, and the object that uses the stream is called the target stream; ...

The invention discloses a streaming media distribution method and a device, which are invented aiming at the defects that in the prior art, the distribution efficiency is low, and other target streams are affected when one path of target stream is abnormal. The method comprises the following steps of: step S101, judging whether a source stream is created or not, if not, turning to a step S201, and if yes, turning to a step S301; step S201, creating the source stream, and turning to the step S301; step S301, creating a target stream; step S401, adding the source stream to the target stream; step S501, distributing the target stream; step S601, stopping the distribution after the target stream receives a command; step S701, deleting the target stream through the source stream; step S801, destroying the target stream; step S901, judging whether the target stream in the source stream is deleted or not, if yes, turning to a step S1001, and if not, finishing the process; and step S1001, destroying the source stream, and finishing the process.
Description
technical field [0001] The invention relates to the field of wireless data transmission, in particular to a streaming media distribution method and device. Background technique [0002] At present, when streaming media is forwarded, a certain method is generally used to distribute the streaming media. There are two main forms of distribution. One form is to convert the source flow of the unicast protocol into the target flow of the multicast protocol for distribution. This method needs the support of routing for multicast, so it is mainly used for distribution in the LAN. The second form is that the forwarding server multiplexes the source streams and distributes them into multiple target streams using a unicast protocol. This method requires the forwarding server to adopt a certain method to multiplex the source stream. Mobile front-end devices generally use WAN to communicate with servers, so the distribution of mobile streaming media will mainly take the second form. T...
