Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings. The accompanying drawings are used to help understand the technical solutions of the embodiments, and implementation may not be limited to the forms shown in the accompanying drawings.

[0028] In this example, if figure 1 As shown, the data is first read from the streaming media file and then packaged to obtain multiple data packets, and the dumping time of each data packet is set; then check every preset time interval, if there is currently a data packet dumping When the storage time arrives, the data packet is transferred to the sending interface, and then the data packet is sent by the sending interface, otherwise, continue to check whether the data packet dumping time arrives. This method can be performed by a media server on the network side, and the media server has a sending interface for sending media data to the user's ter...

Abstract

The invention provides a method and a device for transmitting stream media data, which solve the problem that the service quality of a media server is reduced because the time accuracy of delay system call or timer system call is poorer. The method in the embodiment comprises the following steps: reading data from a stream media file and then packing the data to obtain a plurality of data packets, and setting unloading time of each data packet; detecting whether the unloading time of the data packets arrives or not every preset time interval, and unloading the data packets to a transmission interface after determining that the unloading time of the data packets arrives, and transmitting the data packets by the transmission interface. For the media server providing the stream media data for a terminal through a network, the technical scheme using the embodiment can improve the service quality.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and device for sending streaming media data. Background technique [0002] In the application of the streaming media server based on the Linux operating system, a large amount of streaming media data needs to be transferred from the disk to the network. When streaming media data is transmitted from the disk to the network, the packet sending interval needs to be controlled according to the format of the media. [0003] The transmission of streaming media data from the disk to the network is performed by the media server, which mainly includes the following three steps: (1) read the streaming media data from the disk space into the user data cache; (2) read the stream stored in the user data cache The media data is packaged into RTP (Real-time Transport Protocol) data packets and then sent to the user's sending buffer; (3) the RTP data packets stored in the use...
