PURPOSE: A MPEG-2 transport stream encoder is provided to generate a transport stream packet by configuring one packetized elementary stream packet as one frame. CONSTITUTION: A MPEG-2 TS(Transport Stream) encoder includes a PES(Packetized Elementary Stream) header generator(10), a control signal...
FFMpeg MPEG2的TS流的解码流程
MPEG-2 Transport streams tMyn 1 MPEG-2 Transport streams • The MPEG-2 Systems Standard specifies two methods for multiplexing the audio, video and other data into a format suitable for transmission and storage, namely the program stream and the transport stream. • The Program Stream is de...

wiki上说“An elementary stream (ES) is defined by MPEG communication protocol is usually the output of an audio or video encoder” 恩,很简单吧,就是编码器编出的一组数据,可能是音频的,视频的,或者其他数据 说到着,其实可以对编码器的流程思考一下,无非是执行:采样,量化,编码这3个步骤 ...
TS(Transport Stream): PS(Program Stream): 这两个上面已经有所提及,后面会详细分析TS,我对PS格式兴趣不大. 3.步入正题 才进入正 题,恩,看来闲话太多了:(,直接看Code. 前面说 过,TS是一种传输协议,因此,对应到FFmpeg,可以认为他是一种封装格式。因此 ...
离散馀弦变换编码器主要是利用空间上的冗馀(Spatial Redundancies),而动态估计及补偿器则是利用时间上的冗馀(Temporal Redundancies)来压缩资料;最后资料经过可变长度编码器编码后送至MPEG-2的系统多工器(System Multiplexer,SysMux),再由Transport或Program Stream将资料送出。
The Microsoft MPEG-2 Encoder filter encodes MPEG-2 audio and video and multiplexes the streams to generate an MPEG-2 program stream or transport stream. Nóta This filter is not supported on IA-64-based platforms. Filter Information Filter Interfaces ...
