Hyperthreading technology and parallel computing Analysis in H.264 Encoder [Author: Wang Yu, Lin Tao, Tongji University] H.264 is a new generation of video compression standard jointly developed by ITU-T and ISO. Compared with the previous standards, the computing accuracy and some specific algorithms are greatly improved. These improvements enable H.264 to provide higher compression ratios and lower bit rates. Ho

Principle of incremental rotary encoder The incremental rotary encoder converts the sequence and Phase Relationships of its angle data disk through two photosensitive receiver tubes, and obtains the increase (positive direction) or decrease (negative direction) of the angle data disk displacement ). After joining a digital circuit, especially a single-chip microcomputer, the incremental rotary

Simplest Video Encoder: Compile Recently I have studied several common video encoders: x264, x265, and vpx. This article briefly records their compilation methods. The three open-source video encoders x264, x265, and vpx can be said to be the "most popular" Video Encoder today. X264 currently occupies H. 264 video encoder is half the country; x265 is the best ope

serialization is not very good, so many times we need to use other serialization methods, Common have kryo,jackson,fastjson,protobuf and so on. What we want to write here is not the focus of what serialization is, but how we design our decoder and encoder.First we write a encoder, we inherit from the messagetobyteencoder @Override protected void encode (channelhandlercontext ctx, Object msg, bytebuf out) throws Span style= "color: #000000;" > E

Coding | Scripting Overview A scripting encoder is a simple command-line tool that enables script designers to encode the final script so that Web hosts and Web clients cannot view or modify their source code. Note that this code only prevents others from accidentally looking at your code, and does not prevent a deliberate hacker from viewing your encoded content and its methods. Web Designer in the Web page and server Active Sever pages (. ASP), en

This article introduces a simple Video Encoder Based on FFMPEG. The YUV420P pixel data is encoded as H.264 compressed data. The code of the encoder is very simple, but every line of code is very important. It is suitable for a good study. After the code is clarified, the encoding process of FFMPEG is basically clarified. At present, although I have already completed the program, I still haven't fully unders

1. The main task accomplished was the ability to translate English into French, using a encoder-decoder model, in which the sequence was transformed into a vector in the encoder RNN model. In decoder, a vector is transformed into an output sequence, and encoder-decoder can be used to add sequential information between words and words.2. Another task is to express

For a sparse automatic encoder trained, I want to see what the learned function looks like. For an image trained, calculate the output value of each hidden layer node: The Visualized function is a function calculated by the hidden layer node, which takes a 2D image as the input parameter (ignoring the offset. In particular, we regard it as a non-linear feature of input. We would like to know: what kind of image can make it the biggest incentive? Anot

With the completion of my graduation thesis, I finally made room for free these two days, and I had time to study FFMPEG. I thought that I had been engaged in FFMPEG decoding and seldom involved in FFMPEG encoding. So I plan to study FFMPEG encoding. I read some examples on the Internet and found that it would be slightly more difficult, or the class library would be outdated, so I decided to develop an encoding example for later study. The encoder in
