mpeg4 ts

Recently I am working on merging TS with es + audio of AVS, so the first time involved in the audio section is involved. Some explanations about audio are more messy than video, but this article is a good introduction. Http://mpgedit.org/mpgedit/mpeg_format/mpeghdr.htm It is clear to analyze the audio frequency header information. However, only layer I II III of MPEG-1 MPEG-2 is involved, and the ADTs section used in MPEG2,

on the AV object in the AV scenario. The MPEG-4 standard consists of six main parts: ① DMIF (the dellivery multimedia integration framework) DMIF is the overall multimedia transmission framework. It mainly solves the Operation Problems of multimedia applications in interactive networks, broadcast environments, and disk applications. Establishes interaction and transmission between the client and the server by transmitting multi-channel merging bit information. Through DMIF,

incentive-running-response system for interaction between a human machine. The excitation-response time t is represented by the excitation-response time tc of the circuit system and the software running time ts. The excitation-response time of the circuit system is a small amount of higher order than the software running time, therefore, the software running time forms the main component of T, T = TC + ts

The implementation code is as follows: /* Add the specified sample to the specified time series "Event ". * This function is usually called via latencyaddsampleifneeded (), that * is a macro that only adds the sample if the latency is higher than * server. latency_monitor_threshold. * // * Add the sample to the sample list of the specified event object */void latencyaddsample (char * event, mstime_t latency) {// locate the delayed sample record struct latencytimeseries *
