Java uses Apache commons codec for MD5 encryption, BASE64 encryption and decryption, and executes system commands, commonsbase64
Before writing the code, let's first introduce the two packages we will use;
Commons-codec-1.10.jarTool packages used to process common encoding methods in the Commons project, such as DES, SHA1, MD5, Base64, URL, and Soundx.
Commons-exec-1.3.jarApache Commons Exec is a Java proje
I. PrefaceFFmpeg is an open source project based on Linux development, and its source code is incompatible with the C + + compiler provided by the most common Visual Studio under Windows, so it does not support msvc++ compilation. You need to configure a Linux-like compilation environment under Windows to compile.Compiling the dynamic-link library DLLs will make no difference in usage as with other dynamic-link libraries. You can use msvc++ to link these libraries to other programs, in other wor

The arm11 hardware codec routine provided by Hua Heng.Abstract: This article introduces how to transmit the data collected by cameras over the network after hardware Encoding Based on the hh3c platform. The client (Linux) receives and displays the data in real time over the network; this article mainly introduces the hard
Java8 BASE64 Codec Java has always lacked the BASE64 encoding API, which is often used by third-party API implementations in project development. However, Java 8 implements the BASE64 codec API, which contains the Java.util package. I'm going to do an introduction to the Java 8 BASE64 API below. The Java.util.Base64 tool class provides a set of static methods for obtaining the following three BASE64 codecs

about Opus
The Opus codec is a specially designed interactive voice and audio transmission for the Internet. It was designed by the IETF's codec workgroup, merging Skype's silk and xiph. ORG's Celt technology.The Opus codec is designed to handle a wide range of interactive audio applications, including voice over IP,

Many smartphones now support multimedia features, especially audio and video playback, and the AMR file format is a widely supported audio file format for mobile phones. AMR, full name: Adaptive multi-rate, Adaptive multi-rate, is an audio encoded file format d
In "Let WEBRTC support H264 codec" I provide a priority to use the H264 codec thinking. We can verify it on the browser side.
There are three ways to verify: In JS print SDP view Chrome's log chrome_debug.log (see Open Chrome Log) Grab bag using webrtc-internals
The first three kinds are no longer introduced, we look at the webrtc-internals.
The WEBRTC status information in the current browser can be see

Java Implementation BASE64 codecAuthor: Chszs, reproduced in the note. Blog home:Http://blog.csdn.net/chszsBASE64 and other similar coding algorithms are often used to convert binary data into textual data, which is intended to simplify storage or transmission. In more detail, the BASE64 algorithm is primarily used to convert binary data into ASCII string formats.The Java language provides a good implementation of the BASE64 algorithm, the Apache Commons cod
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 pa
When writing a file using Python, or when writing a network stream to a local file, in most cases you will encounter: Unicodeencodeerror: ' GBK ' codec can ' t encode character ' \xa0 ' in position ... The problem. There are a lot of similar files on the network about how to solve this problem, but nothing is encode,decode related, is this the real cause of the problem? No. Many times, we used decode and encode, tried all kinds of code, utf8,utf-8,gbk
