Abstract

The invention discloses a non-interlaced audio data reading method and device, and relates to the technical field of streaming media. The method includes: intercepting the original instruction for reading the data block of the TS stream file; according to each video frame number in the original instruction, finding the information of each data packet corresponding to the video frame number in the source file; according to the Describe the data packet information of each video frame number, extract each audio frame information corresponding to the video frame number requirement; generate a minimum audio data read command for each audio frame information, and read the audio according to the minimum audio data read command framedata; returns the audio frame data as the audio data of the original instruction. The present invention only reads audio data and does not read any other invalid data, which greatly reduces the amount of data read, thereby saving system resources, especially a lot of bandwidth resources in a network environment, and reducing the load of the system.

Description

technical field [0001] The invention relates to the technical field of streaming media, in particular to a non-interleaved audio data reading method and device. Background technique [0002] With the rapid development of multimedia video services, the storage media of files is not limited to cassettes or CDs. TS (Transport Stream, which is suitable for wireless transmission, is a transport stream. TS streams are composed of many different types of packets. These data packets are 188 or 192 bytes in size, these bytes contain two parts, the header and the data load, the header includes synchronization information, packet information, etc., and the data load is the transmitted data, and these loads can be composed Data streams such as PES streams (Packetized Elementary Streams, packaged elementary streams) or private streams, because of the above structure, when the transmission error destroys the synchronization information of a TS packet, the receiver can detect it in the pac...
