解决Android平台移植ffmpeg的一揽子问题

IT行业是一个踩在巨人肩膀上前进的行业，否则做的事情不一定有意义，所以我也是基于havlenapetr移植的ffmpeg基础上做了些改进，他做的主要贡献有：

1. 移植了ffmpeg并将与媒体相关的结构体在java层重新进行了封装，方便应用程序在java层直接操作ffmpeg API,如各种媒体格式转码及播放，如图1所示

2. 模仿Android的MediaPlayer类实现了ffmpeg的播放接口，如setDataSource(),setDisplay(),start(), stop(),pause()等，缺点是没有实现seek功能。

3. 实现了一个简单播放器功能，抛弃掉ffmpeg自带的ffplay播放器，他重新实现了音视频的分离播放和同步处理等播放器应有的功能。

基于Android移植ffmpeg的意义在于：

1.解决了Android媒体框架OpenCore的多媒体支持不足，虽然说Android平台的软解功耗大，但是从PC机的发展历史看，Android的视频处理以后也会走以硬解为主，软解为辅的路线。

2. 解决Android平台直播的问题，虽然Android支持RTSP/RTP的直播方案，但是这种方案主要是普遍用在电信设备上，基于互联网的海量视频服务提供者还是以http live streaming方案为主，测试时可以用ffmpeg将直播流打包成分段的ts流(如10秒钟),然后组织成m3u8文件实现完整的直播方案，而且互联网的直播内容还有很多是基于mms协议的，视频格式是wmv,要聚集这些内容都是离不开ffmpeg软解的。

 

移植步骤：

1. 下载havlenaptr移植的ffmpeg(https://github.com/havlenapetr/FFMpeg/zipball/debug).

2.  基于ndk编译下载的ffmpeg,出现的编译问题主要是文件的存放路径不对，修改jni目录下的Android.mk文件，增加头文件目录$(LOCAL_PATH)/../include/android，修改Vector.h文件为：

#include <cutils/log.h>
#include <utils/VectorImpl.h>
#include <utils/TypeHelpers.h>

3.utils目录下缺少TypeHelpers.h，添加该文件：

4.编译中出现 make: *** No rule to make target `/cygdrive/e/workspace/myffmpeg/obj/local/armeabi/libjniaudio.so', needed by `/cygdrive/e/workspace/myffmpeg/obj/local/armeabi/libmediaplayer.a'.  Stop. 需要把下载的ffmpeg中的libjniaudio.so和libjnivideo.so放到错误中指定的目录下。

 

5. 编译成功后运行的结果如下：

    

 

当点击媒体文件播放时，发现画面显示不正常，如下所示：

 

调试后发现MediaPlayer.cpp中没有像Android自带播放器一样实现OnVideoSizeChangedListener的回调函数，当播放视图(SurfaceView)创建后没有根据实际播放的视频大小做调整，而且画面没有居中显示，所以我在此基础上做了如下改进

1. 实现OnVideoSizeChangedListener接口，通知播放界面调整大小

2. 播放界面剧中显示，等比率缩放视频大小。

3. 实现Seek功能

• 3.1 要实现getCurrentPosition(), 因为拖动时传过来的是时间millisecond
• 3.2 把milli second转化成timestamp掉用av_seek...
• 3.3 在IDecoder类里面加入flush函数,实际上就是seek的时候把队列里的AVPacket清除掉
• 3.4 通过av_gettime()函数作为外部参考时钟，实现音视频同步，需要hurryup和实现drop frame的处理。

 

下面是调整后播放flv(h264+aac)格式（分辨率为320*240，25帧/S)的结果，软解播放达到平均22帧/s

 

 

其它wmv,ts流,avi等格式均可播放，但是音质效果需要改进。

 

最近的进展情况：

 

1. 实现ffmpeg播放的回调接口，可以通知界面刷新状态，如去掉缓冲提示等。 

public interface IFFMpegPlayer {
     public void onPlay();
     public void onStop();
     public void onRelease();
     public void onError(String msg, Exception e);
    }

2. 定制话播放控制栏界面，效果如下：

 

替换ffmpeg自带的控制栏界面

 

如何支持http网络播放，需要config.h里enable相关选项，我的配置参考如下：

FFMpeg自带的播放器ffplay对音视频的处理方法总结：

1. 如果声音是CBR的（也就是固定码率），就以音频的时间戳为基准

2. 如果视频时CBR，就以视频的时间戳为基准

3. 如果都是VBR的，就参考外部时钟，通过av_gettime()获取微妙集的时钟。

 

ffmpeg通过AVStream结构的time_base（有理数由分子和分母组成）可以获取一个参考时间单位，所有音视频流的timestamp都是基于这个时间单位顺序递增，比如time_base.num=1,time_base.den=90000,表示把1秒分成90000等份，音视频的pts和dts值就表示有多少个1/90000等份，更简单一点假设time_base.num=1,time_base.den=1000,就表示1秒分成1000等份，相当于1毫秒，那时间戳就表示是以毫秒为单位的，再做音视频处理时候，如果解码的速度比按照时间戳显示的速度快，那就简单不用丟帧（Drop Frame）处理，当解码速度很慢时(比如手机设备),就需要丢帧处理，是每两帧丟一帧数据，还是每3帧丟掉一帧数据，就需要根据延时显示程度来计算丢帧的比率

 

havlenapetr最新的ffmpeg可以直接编译通过，不过有个bug,就是播放完毕后，video_decoder线程不能退出，主要原因是阻塞在packet队列的Queue->get函数里，这里处理逻辑需要考虑两种情况：

1. AVPacket队列里没有音视频帧数据时，解码线程挂起进入等待状态，有新的AVPacket加入队列时激活解码线程

2. 如果文件读取到末尾，Queue->get直接返回-1，解码线程发现队列空时直接退出
