This article complements the two examples in the simplest ffmpeg+sdl-based audio player: The FFmpeg audio decoder and the SDL audio sampling data player. These two sections are the two examples that are split out from the audio player. The FFmpeg audio decoder enables the decoding of video data to PCM sampled data, while the SDL audio sampling data player enables the playback of PCM data to audio devices. I

H.264 reference image management in decoderPeter Lee 2005.11.24 videosky.9126.com [preface] Because H.264 adopts multi-Reference Frame Prediction Technology, it is complicated to manage reference images. Go50 only explains how to use it and does not explain why it is used. After reading it, you may have many questions. This article provides a detailed explanation of the problem of reference image management, aiming to further unveil its haze. :) Note: to facilitate the management of reference im
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:

Libmad: is an open source High-precision MPEG Audio Decoder library that supports MPEG-1 (Layer I, Layer II and LAYERIII (i.e. MP3). Libmad provides 24-bit PCM output, fully fixed-point computing, and is ideal for use on platforms without floating-point support. With a series of APIs provided by Libmad, MP3 data decoding can be done very simply. In the Libmad source code file directory of the Mad.h file, you can see most of the library's data structur

Create an MP3 decoder-use mad (MPEG audio decoding library) in Symbian
Some time ago, I wrote a program on newlc.com to create an MP3 player for Series 60. I have received many emails about MP3 decoding and using it on Symbian. Here, we use mad (MPEG audio decoding library) in Symbian to solve the problem.
Overview
Because in Symbian 7.0, you can use MMF to play MP3 videos in smartphones. However, if your mobile phone does not support MP3 decoding, o
In H.264 decoder, the implementation of cabac hardware accelerator H.264 has two kinds of entropy encoding solutions: one is context-based adaptive variable-length encoding developed from the variable-length encoding solution, and the other
One is context-based adaptive binary arithmetic code cabac developed from arithmetic coding. Compared with cavlc, cabac can save about 7% of the bitstream, but increase the computing speed by 10%.

Decoding is the inverse process of encoding. Its function is to identify binary codes with specific meanings and convert them into control signals. A logic circuit with decoding function becomes a decoder.The decoder can be divided into two types:CodeConvert to one of the valid signals. This
