最简单的基于FFmpeg的音频播放器 2 (SDL 2.0) Simplest FFmpeg Audio Player 2 (SDL 2.0) 雷霄骅 Lei Xiaohua leixiaohua1020@126.com 中国传媒大学/数字电视技术 Communication University of China / Digital TV Technology http://blog.csdn.net/leixiaohua1020 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。 该版本使用SDL 2.0替换了第一个版本中的SDL 1.0。 注意:SDL 2.0中音频解码的API并无变化。唯一变化的地方在于 其回调函数的中的Audio Buffer并没有完全初始化,需要手动初始化。 本例子中即SDL_memset(stream, 0, len); This software decode and play audio streams. Suitable for the beginner of FFmpeg. The solution contains 3 projects: simplest_ffmpeg_audio_player: Audio player based on FFmpeg and SDL. simplest_ffmpeg_audio_decoder: Audio decoder. Uses libavcodec and libavformat. simplest_audio_play_sdl2: Example about using SDL2 play PCM data. This version use SDL 2.0 instead of SDL 1.2 in version 1 Note:The good news for audio is that, with one exception, it's entirely backwards compatible with 1.2. That one really important exception: The audio callback does NOT start with a fully initialized buffer anymore. You must fully write to the buffer in all cases. In this example it is SDL_memset(stream, 0, len);
