This article briefly translated the x264 option (encoding option, which is later called the English name) analysis report x264 codec strong and weak points by MSU lab. After reading it, I felt that the analysis was very thorough, and the method used was also very useful for reference. Therefore, I should record the key points in the analysis for memo. As we all know, there are a lot of options for x264. It is really a headache to combine these many parameters to make the encoded video smaller in

End-to-end neural network MT (end-to-end Neural machine translation) is a new method of machine translation emerging in recent years. In this paper, we will briefly introduce the traditional method of statistical machine translation and the application of neural network in machine translation, then introduce the basic coding-decoding framework (Encoder-decoder) in NMT.Reprint Please specify source: http://blog.csdn.net/u011414416/article/details/51048

Update (originalpwd. getbyetes ());Byte [] digestedbytes = md. Digest (); It also uses the message digest to create a unique ID (also called a digital fingerprint) of the checksum and text ). When the ARJ file is signed, the checksum is calculated based on the content of the ARJ file an

The basic description of speex includes a command line encoder and decoder. these tools generate and read the speex files packaged in the Ogg container. although it can encapsulate speex in any container, Ogg is recommended as a file container. this section describes how to use the command line tool for the speex file of Ogg. 4.1 speexencThe speexenc unit is used to create a speex file through a raw PCM or wave file. You can use the following command:

close to an envelope. That is to say, the "best preset" is not affected by the video content (of course, there is still a little bit, but the degree is not big ). This report uses the "bus" test video sequence experiment results. Summary This report uses four methods to analyze the x264 option:1. Use convex hull to analyze the optimal option. 2. Use the "color Cloud Chart" to analyze the option. This method is simple and intuitive, but cannot be accurately quantified. 3. Use Lambda paramete

Refer to the following article:http://blog.csdn.net/a992036795/article/details/54286654First, prefaceAs I said in the previous article, I used libx264 to encode video h264 very inefficiently, because libx264 uses soft coding. So I searched online to learn that using the system API can hard code video, thereby reducing the pressure on the CPU, to improve the efficiency of the role. I wrote a demo and tried it, and it was obvious that efficiency was improved.second, the idea1. Core class Med
