mp4 to mpeg2

MPEG2 encoder can be divided into two layers: compression layer and reuse layer. Es streams are generated from the compression layer.ES--PES, and then reuse can be PS stream or TS stream, PS is used for storage (such as DVD) ts for transmission (such as TV station playback ). In multimedia signal transmission, high-quality sound and images can be parsed only when audio and video signals are effectively encoded. This article introduces

1. Macro Block matching pixel precision: In MPEG2, the motion estimation accuracy is 12 pixels, which can be implemented through linear insertion (which may be simply corrected ); both H264 and MPEG4 support 14-pixel precision. 2. Number of reference frames: MPEG2. P frames of MPEG4 can only have one reference frame, and B frames can have two reference frames. H. 264 can have up to 15 reference frames, one

mp4 should be considered a more complex media format, originating from QuickTime. It took a while to study, especially how to integrate it perfectly into the video-on- Demand application, but also a great deal of effort, the main problem is to handle the large "media head" of MP4 file. Of course, streaming media On demand can also be used in the FLV format, FLV can also encapsulate the video data, but Ad

It should be said that after truly understanding TS and reading the book "digital TV business information and coding" recommended by friends, MPEG2 TS and digital TV are closely inseparable, it is worth summarizing some of these relationships.

To put it simply, the MKV and AVI formats only encapsulate containers, which encapsulate video streams and audio streams. The container does not affect the image quality. What affects the quality is what is encapsulated in the container. Therefore, changing the container does not affect definition subtitle audio. I would like to add some basic knowledge about video. Maybe there is something wrong with it. First, the video format does not determine the definition. The definition of a video depend

Generally, there is a unit separator nal at the beginning, and the data packet between the two unit delimiters is an image. 00 00 01 09, which is the unit separator. However, the Protocol does not say that the nal stream must be so organized, and there may be other forms of organization. My h264 files are organized in this way. The byte stream of h264 does not have the frame concept. Please carefully study the protocol for specific reasons. It depends on how you understand it. Compared with

The preceding three sections summarize the basic formats of MPEG2 ts, including PES, PS, ts, and related fields. As a transmission stream, TS will package and reuse the content, convert the media content into ts for transmission, and finally decode the content on the decoding end. To put it simply, ts is a transport layer protocol stack that supports transmission of various content, such as MPEG, WMV, h264, and even IP addresses, how is the transmissi
