packaging, the screen video files and track files packaged together, and according to certain rules to establish sorting and indexing, easy to play player or play software to index playback. Includes Avi/ps (program Stream)/TS (Transport Stream)/MKV (Matroska), etc. 4) I frame: Intra-frame coding frame is also called Intra picture,i frame is usually the first frame of each GOP (MPEG

familiar with, is the 263 video logo. (If there is audio data, it will be with the video data staggered together, but our goal is only real-time coding video streaming, do not need to process audio, so in the initialization of the Mediarecorder I do not want to Mediarecorder.setaudiosource, so there's no audio data. ）

3D-HEVC Coding Framework3D-HEVC coding structure is the expansion of HEVC, each point of view texture and depth map coding mainly using HEVC coding framework, but on the basis of a number of new coding techniques to make it more conducive to depth and multi-view coding.Figur

Bit rate control is actually a coding optimization algorithm, which is used to control the video stream size. So what is the purpose of its control? We can imagine that the same video encoding format, the code flow is large, it contains more information, then the corresponding image is clearer, and vice versa. The two current control modes are VBR and CBR,VBR are

Static Image Compression and is applicable to consecutive color or grayscale images. It consists of two parts:1. distortion-free Coding Based on DPCM (spatial Linear Prediction) technology, 1. distortion-free Algorithms Based on DCT (discrete cosine transformation) and Harman coding,The compression ratio is very small, and the latter algorithm is mainly used.The most common method in nonlinear editing is t

0 IntroductionWith the development of video coding and decoding technology, computer network technology, digital signal processing technology and embedded system, the remote video surveillance system with embedded network video server as the core has begun to emerge in the market. The system transmits the analog

. Background Knowledge This chapter mainly introduces where FFmpeg is used (only a few of what I know here is actually far more than this ). To put it bluntly, FFmpeg is very important. Use FFMPEG as the kernel Video Player: Mplayer, ffplay, shooter player, storm video, kmplayer, QQ video... Use FFMPEG as the DirectShow filter of the kernel: Ffdshow, LAV fil

1. Video Coding ConceptsVideo encoding refers to the way in which a video format file is converted to another video format file by a specific compression technique .2. Why video compression? Data is too large: uncompressed digital

HEVC Video Coding FrameworkThe HEVC coding framework is similar to the H.26X standard coding framework, and is based on a mixed block model.Figure 1 HEVC Coding Framework1. First, the video encoder divides the input

usually low, for some information or even no compression effect, without regard to the Code table, Huffman coding compression rate is higher However, in fact, for video compression, the advantages of similar to the compression ratios provided by Huffman coding are far from sufficient, and additional code tables are required. Therefore, in the actual
