" H.264/AVC Video Codec technology detailed" video tutorial has been in the "CSDN College" on-line, the video details of the background, standard protocol and implementation, and through a practical project in the form of the standard of the resolution and realization of H. A, welcome to watch. "The paper came to the end of the light, I know this matter to preach", only by themselves in accordance with the standard document in the form of code to op

FLV (Video: H. +, Audio: AAC) transcoding to AVI (Video: MPEG2, audio MP3). The process of visible video transcoding is generally the equivalent of "recording" the video and audio again.This procedure works as shown in the following diagram:By the figure, this program does not do video and audio codec work, so this program and ordinary transcoding software compared to the following two features:Processing speed is extremely fast. The audio

Video is an important part of Multimedia Systems in computers. To meet the needs of video storage, people have set different video file formats to put the video and audio in one file for simultaneous playback. Video files are actually a container that contains different tracks. The Container formats used are related to the scalability of video files. FourCC is the Four-Character Codes. It consists of 4 characters (4 bytes) and is a Four-byte format that uniquely identifies the video data stream,

After reading the introduction of H264/AVC codec, I just left the following three articles in my mind:1, H264 does not understand how to implement a codec, just a coded video bit stream syntax, and the Bitstream decoding method, this is similar to MPEG.2, H264 and once the standard (such as H261, H263, MPEG-1, MPEG-4) codec implementation process is not much diff

How to compile the Opus audio codec library for AndroidThe Opus audio codec library is the next generation of the Speex audio codec library. It has made great progress in terms of codec performance and quality. Opus compilation is very simple, but the official did not provide a detailed Android version Compilation Guid

In addition, Samsung's linux BSP is open-source to drive it. A friend who has read the MFC driver will surely find out that the kernel need

commons-codecis a package provided by the Apache Open source organization for digest operations and encoding. In this package is divided into four types of encryption: Binaryencoders, Digestencoders, Languageencoders, Networkencoders.Today I would like to introduce you how to use commons-codec the package to complete the common coding, digest operations.Base64Example code:@TestpublicvoidtestBase64(){ System.out.println("==============Base64=========

OpenSSL to Base64 codec specification support is poor, using it to encode and decode the results of other languages such as PHP processing is not convenient, notice a few of the following collation1, if the PHP encryption results do base64 encoding length less than 64, you need to add a newline character OpenSSL to decode;2,php needs to insert a newline character for Base64 encoding results every 64 characters, and OpenSSL decodes it. (The reason is t

"unicodeencodeerror: ' ASCII ' codec can ' t encode"Python default environment encoding can be obtained by using the following method:　　The ASCII encoding is essentially the way in which Python naturally calls the ASCII codec to process the character stream, and throws an exception if the character stream is not within the ASCII range (ordinal not in range (128)).The solution is simple, modify the default e

For Java-provided object input and output streams ObjectInputStream and ObjectOutputStream, you can write Java objects directly to the file as a stored byte array, or you can transfer them to the network. For Java developers, the default JDK serialization mechanism avoids manipulating the underlying byte array, which can improve development efficiency.1. Why serialization is requiredNetwork Transmission and serialization of ObjectsWhat the 2.java codec
