最简单的基于FFmpeg的视频播放器 2 Simplest FFmpeg Player 2

本程序实现了视频文件的解码和显示(支持HEVC,H.264,MPEG2等)。 是最简单的FFmpeg视频解码方面的教程。 通过学习本例子可以了解FFmpeg的解码流程。 项目包含6个工程: simplestffmpegplayer:标准版,FFmpeg学习的开始。 simplestffmpegplayersu:SU(SDL Update)版,加入了简单的SDL的Event。 simplestffmpegdecoder:一个包含了封装格式处理功能的解码器。使用了libavcodec和libavformat。 simplestffmpegdecoderpure:一个纯净的解码器。只使用libavcodec(没有使用libavformat)。 simplestvideoplaysdl2:使用SDL2播放YUV的例子。 simplestffmpeg_helloworld:输出FFmpeg类库的信息。

备注: 标准版在播放视频的时候,画面显示使用延时40ms的方式。这么做有两个后果: (1)SDL弹出的窗口无法移动,一直显示是忙碌状态 (2)画面显示并不是严格的40ms一帧,因为还没有考虑解码的时间。 SU(SDL Update)版在视频解码的过程中,不再使用延时40ms的方式,而是创建了 一个线程,每隔40ms发送一个自定义的消息,告知主函数进行解码显示。这样做之后: (1)SDL弹出的窗口可以移动了 (2)画面显示是严格的40ms一帧

This software is a simplest video player based on FFmpeg. Suitable for beginner of FFmpeg. Solutions contains 6 Project: simplestffmpegplayer: Standard Version, suitable for biginner. simplestffmpegplayersu: SU(SDL Update)Version, Add SDL Event. simplestffmpegdecoderpure: A pure decoder. Only use libavcodec (Without libavformat). simplestffmpegdecoder: A decoder that can demux container format. Uses libavcodec and libavformat. simplestvideoplaysdl2: Example about using SDL2 play YUV data. simplestffmpeg_helloworld: Output informations about FFmpeg libraries.

Remark: Standard Version use's SDLDelay() to control video's frame rate, it has 2 disadvantages: (1)SDL's Screen can't be moved and always "Busy". (2)Frame rate can't be accurate because it doesn't consider the time consumed by avcodecdecode_video2() SU(SDL Update)Version solved 2 problems above. It create a thread to send SDL Event every 40ms to tell the main loop to decode and show video frames.
