快速解決Android平台移植ffmpeg的一些問題

IT行業是一個踩在巨人肩膀上前進的行業，否則做的事情不一定有意義，所以我也是基於havlenapetr移植的ffmpeg基礎上做了些改進，他做的主要貢獻有：

1. 移植了ffmpeg並將與媒體相關的結構體在java層重新進行了封裝，方便應用程序在java層直接操作ffmpeg API,如各種媒體格式轉碼及播放，如圖1所示

2. 模仿Android的MediaPlayer類實現了ffmpeg的播放接口，如setDataSource(),setDisplay(),start(), stop(),pause()等，缺點是沒有實現seek功能。

3. 實現了一個簡單播放器功能，拋棄掉ffmpeg自帶的ffplay播放器，他重新實現了音視頻的分離播放和同步處理等播放器應有的功能。

基於Android移植ffmpeg的意義在於：

1.解決了Android媒體框架OpenCore的多媒體支持不足，雖然說Android平台的軟解功耗大，但是從PC機的發展歷史看，Android的視頻處理以後也會走以硬解為主，軟解為輔的路線。

2. 解決Android平台直播的問題，雖然Android支持RTSP/RTP的直播方案，但是這種方案主要是普遍用在電信設備上，基於互聯網的海量視頻服務提供者還是以http live streaming方案為主，測試時可以用ffmpeg將直播流打包成分段的ts流(如10秒鐘),然後組織成m3u8文件實現完整的直播方案，而且互聯網的直播內容還有很多是基於mms協議的，視頻格式是wmv,要聚集這些內容都是離不開ffmpeg軟解的。

移植步驟：

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

2.  基於ndk編譯下載的ffmpeg,出現的編譯問題主要是文件的存放路徑不對，修改jni目錄下的Android.mk文件，增加頭文件目錄$(LOCAL_PATH)/../include/android，修改Vector.h文件為：

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

3.utils目錄下缺少TypeHelpers.h，添加該文件：

4.編譯中出現 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. 需要把下載的ffmpeg中的libjniaudio.so和libjnivideo.so放到錯誤中指定的目錄下。

5. 編譯成功後運行的結果如下：

當點擊媒體文件播放時，發現畫面顯示不正常，如下所示：

調試後發現MediaPlayer.cpp中沒有像Android自帶播放器一樣實現OnVideoSizeChangedListener的回調函數，當播放視圖(SurfaceView)創建後沒有根據實際播放的視頻大小做調整，而且畫面沒有居中顯示，所以我在此基礎上做了如下改進

1. 實現OnVideoSizeChangedListener接口，通知播放界面調整大小

2. 播放界面劇中顯示，等比率縮放視頻大小。

3. 實現Seek功能

3.1 要實現getCurrentPosition(), 因為拖動時傳過來的是時間millisecond3.2 把milli second轉化成timestamp掉用av_seek...3.3 在IDecoder類裡面加入flush函數,實際上就是seek的時候把隊列裡的AVPacket清除掉3.4 通過av_gettime()函數作為外部參考時鐘，實現音視頻同步，需要hurryup和實現drop frame的處理。

下面是調整後播放flv(h264+aac)格式（分辨率為320*240，25幀/S)的結果，軟解播放達到平均22幀/s

其它wmv,ts流,avi等格式均可播放，但是音質效果需要改進。

最近的進展情況：

1. 實現ffmpeg播放的回調接口，可以通知界面刷新狀態，如去掉緩沖提示等。 
復制代碼 代碼如下:
public interface IFFMpegPlayer {
     public void onPlay();
     public void onStop();
     public void onRelease();
     public void onError(String msg, Exception e);
    }

2. 定制話播放控制欄界面，效果如下：

替換ffmpeg自帶的控制欄界面

如何支持http網絡播放，需要config.h裡enable相關選項，我的配置參考如下：

FFMpeg自帶的播放器ffplay對音視頻的處理方法總結：

1. 如果聲音是CBR的（也就是固定碼率），就以音頻的時間戳為基准

2. 如果視頻時CBR，就以視頻的時間戳為基准

3. 如果都是VBR的，就參考外部時鐘，通過av_gettime()獲取微妙集的時鐘。

ffmpeg通過AVStream結構的time_base（有理數由分子和分母組成）可以獲取一個參考時間單位，所有音視頻流的timestamp都是基於這個時間單位順序遞增，比如time_base.num=1,time_base.den=90000,表示把1秒分成90000等份，音視頻的pts和dts值就表示有多少個1/90000等份，更簡單一點假設time_base.num=1,time_base.den=1000,就表示1秒分成1000等份，相當於1毫秒，那時間戳就表示是以毫秒為單位的，再做音視頻處理時候，如果解碼的速度比按照時間戳顯示的速度快，那就簡單不用丟幀（Drop Frame）處理，當解碼速度很慢時(比如手機設備),就需要丟幀處理，是每兩幀丟一幀數據，還是每3幀丟掉一幀數據，就需要根據延時顯示程度來計算丟幀的比率

havlenapetr最新的ffmpeg可以直接編譯通過，不過有個bug,就是播放完畢後，video_decoder線程不能退出，主要原因是阻塞在packet隊列的Queue->get函數裡，這裡處理邏輯需要考慮兩種情況：

1. AVPacket隊列裡沒有音視頻幀數據時，解碼線程掛起進入等待狀態，有新的AVPacket加入隊列時激活解碼線程

2. 如果文件讀取到末尾，Queue->get直接返回-1，解碼線程發現隊列空時直接退出
