1, open the encoder, set the code frame parameters Profile@level, according to the needs of the direct choice of 720p or 1080p, etc. on the line. 2, the following encoding type (Encoding type) is more important. First is single, which is the simplest type of encoding, with the advantage of being fast, but with the same compression rate per frame, which can be wasteful or inadequate. In general, this is enough, choose Single Pass mode, the followin

Record Cool The settings in the Encoder window will directly affect the video's quality, sound and bitrate. Video size: If you want to record HD video, just select "HD Mode", one of the "original quality" is the best, but the resulting file and network code flow will be the largest, "super clear quality" slightly less clarity, but a small half of the file, fluency will also be much higher, you can choose 1/2 size, will be recorded in half the size;

Windows Media Encoder is an easy-to-use, powerful software that provides users with the ability to record their own images, recording from an image capture device or a desktop screen, and providing the ability to convert file formats. The main features are easy to use, high quality coding, enhanced programmable and management features: New user interface and wizards, easier to set up and make movies, to provide network live playback or demand playback

My blog tells about WMS9, can implement streaming media server, but without WME (Windows Media Encoder) support, always feel the lack of something, Here's how to get the device video audio stream through the. NET implementation WME and push it to remote (of course, local) streaming media broadcast publishing point. First, download the WME9 SDK, installation completed: This step is to experience the main WME can achieve those functions. The reader can

the generation of self-encoder against network Aegan 1 Introduction Autoencoder is a good special functions extraction model, however, if we use Autoencoder's decoder part as a generator, the effect is not good, the main reason is that we extract the H itself is a heuristic feature, without any explicit meaning, So when we use decoder to do generation, we can't give a meaningful distribution of H.Gan is the most good generation model, there is also

Switch that specifies that script encoder are to work silently; That is, produce no screen output. If omitted, the default is to provide verbose output. /F Optional.

Compiling ffmpeg (svn version) and x264 (git version) decoding encoder ffmpeg in Ubuntu (Linux) is a tool for decoding and encoding multimedia videos and audio files, it is used to play and convert a large number of multimedia (mainly video and audio) files. X264 is a library file for encoding/decoding H264 video format. It is more efficient than xvid or other popular codecs and provides better image quality after conversion. Avidemux, VLCPlayer, MEnc

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

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

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:
