资源内容介绍

本程序实现了音频的解码和播放。是最简单的FFmpeg音频解码方面的教程。通过学习本例子可以了解FFmpeg的解码流程。项目包含3个工程：simplest_ffmpeg_audio_player：基于FFmpeg+SDL的音频解码器simplest_ffmpeg_audio_decoder：音频解码器。使用了libavcodec和libavformat。simplest_audio_play_sdl2：使用SDL2播放PCM采样数据的例子。

In this * example it is SDL_memset(stream, 0, len); * * Version 2.0 */#include <stdio.h>#include <stdlib.h>#include <string.h>#define __STDC_CONSTANT_MACROS#ifdef _WIN32//Windowsextern "C"{#include "libavcodec/avcodec.h"#include "libavformat/avformat.h"#include "libswresample/swresample.h"#include "SDL2/SDL.h"};#else//Linux...#ifdef __cplusplusextern "C"{#endif#include <libavcodec/avcodec.h>#include <libavformat/avformat.h>#include <libswresample/swresample.h>#include <SDL2/SDL.h>#ifdef __cplusplus};#endif#endif#define MAX_AUDIO_FRAME_SIZE 192000 // 1 second of 48khz 32bit audio//Output PCM#define OUTPUT_PCM 1//Use SDL#define USE_SDL 1//Buffer://|-----------|-------------|//chunk-------pos---len-----|static Uint8 *audio_chunk;
