快速解決Android平臺(tái)移植ffmpeg的一些問(wèn)題

更新時(shí)間：2013年11月02日 09:50:12 作者：

模仿Android的MediaPlayer類(lèi)實(shí)現(xiàn)了ffmpeg的播放接口，如setDataSource(),setDisplay(),start(), stop(),pause()等，缺點(diǎn)是沒(méi)有實(shí)現(xiàn)seek功能

IT行業(yè)是一個(gè)踩在巨人肩膀上前進(jìn)的行業(yè)，否則做的事情不一定有意義，所以我也是基于havlenapetr移植的ffmpeg基礎(chǔ)上做了些改進(jìn)，他做的主要貢獻(xiàn)有：

1. 移植了ffmpeg并將與媒體相關(guān)的結(jié)構(gòu)體在java層重新進(jìn)行了封裝，方便應(yīng)用程序在java層直接操作ffmpeg API,如各種媒體格式轉(zhuǎn)碼及播放，如圖1所示

2. 模仿Android的MediaPlayer類(lèi)實(shí)現(xiàn)了ffmpeg的播放接口，如setDataSource(),setDisplay(),start(), stop(),pause()等，缺點(diǎn)是沒(méi)有實(shí)現(xiàn)seek功能。

3. 實(shí)現(xiàn)了一個(gè)簡(jiǎn)單播放器功能，拋棄掉ffmpeg自帶的ffplay播放器，他重新實(shí)現(xiàn)了音視頻的分離播放和同步處理等播放器應(yīng)有的功能。

基于Android移植ffmpeg的意義在于：

1.解決了Android媒體框架OpenCore的多媒體支持不足，雖然說(shuō)Android平臺(tái)的軟解功耗大，但是從PC機(jī)的發(fā)展歷史看，Android的視頻處理以后也會(huì)走以硬解為主，軟解為輔的路線。

2. 解決Android平臺(tái)直播的問(wèn)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(shè)備上，基于互聯(lián)網(wǎng)的海量視頻服務(wù)提供者還是以http live streaming方案為主，測(cè)試時(shí)可以用ffmpeg將直播流打包成分段的ts流(如10秒鐘),然后組織成m3u8文件實(shí)現(xiàn)完整的直播方案，而且互聯(lián)網(wǎng)的直播內(nèi)容還有很多是基于mms協(xié)議的，視頻格式是wmv,要聚集這些內(nèi)容都是離不開(kāi)ffmpeg軟解的。

移植步驟：

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

2. 基于ndk編譯下載的ffmpeg,出現(xiàn)的編譯問(wèn)題主要是文件的存放路徑不對(duì)，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：

復(fù)制代碼代碼如下:

4.編譯中出現(xiàn) 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(cuò)誤中指定的目錄下。

5. 編譯成功后運(yùn)行的結(jié)果如下：

當(dāng)點(diǎn)擊媒體文件播放時(shí)，發(fā)現(xiàn)畫(huà)面顯示不正常，如下所示：

調(diào)試后發(fā)現(xiàn)MediaPlayer.cpp中沒(méi)有像Android自帶播放器一樣實(shí)現(xiàn)OnVideoSizeChangedListener的回調(diào)函數(shù)，當(dāng)播放視圖(SurfaceView)創(chuàng)建后沒(méi)有根據(jù)實(shí)際播放的視頻大小做調(diào)整，而且畫(huà)面沒(méi)有居中顯示，所以我在此基礎(chǔ)上做了如下改進(jìn)

1. 實(shí)現(xiàn)OnVideoSizeChangedListener接口，通知播放界面調(diào)整大小

2. 播放界面劇中顯示，等比率縮放視頻大小。

3. 實(shí)現(xiàn)Seek功能

3.1 要實(shí)現(xiàn)getCurrentPosition(), 因?yàn)橥蟿?dòng)時(shí)傳過(guò)來(lái)的是時(shí)間millisecond3.2 把milli second轉(zhuǎn)化成timestamp掉用av_seek...3.3 在IDecoder類(lèi)里面加入flush函數(shù),實(shí)際上就是seek的時(shí)候把隊(duì)列里的AVPacket清除掉3.4 通過(guò)av_gettime()函數(shù)作為外部參考時(shí)鐘，實(shí)現(xiàn)音視頻同步，需要hurryup和實(shí)現(xiàn)drop frame的處理。

下面是調(diào)整后播放flv(h264+aac)格式（分辨率為320*240，25幀/S)的結(jié)果，軟解播放達(dá)到平均22幀/s

其它wmv,ts流,avi等格式均可播放，但是音質(zhì)效果需要改進(jìn)。

最近的進(jìn)展情況：

1. 實(shí)現(xiàn)ffmpeg播放的回調(diào)接口，可以通知界面刷新?tīng)顟B(tài)，如去掉緩沖提示等。

復(fù)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(wǎng)絡(luò)播放，需要config.h里enable相關(guān)選項(xiàng)，我的配置參考如下：

FFMpeg自帶的播放器ffplay對(duì)音視頻的處理方法總結(jié)：

1. 如果聲音是CBR的（也就是固定碼率），就以音頻的時(shí)間戳為基準(zhǔn)

2. 如果視頻時(shí)CBR，就以視頻的時(shí)間戳為基準(zhǔn)

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

ffmpeg通過(guò)AVStream結(jié)構(gòu)的time_base（有理數(shù)由分子和分母組成）可以獲取一個(gè)參考時(shí)間單位，所有音視頻流的timestamp都是基于這個(gè)時(shí)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(gè)1/90000等份，更簡(jiǎn)單一點(diǎn)假設(shè)time_base.num=1,time_base.den=1000,就表示1秒分成1000等份，相當(dāng)于1毫秒，那時(shí)間戳就表示是以毫秒為單位的，再做音視頻處理時(shí)候，如果解碼的速度比按照時(shí)間戳顯示的速度快，那就簡(jiǎn)單不用丟幀（Drop Frame）處理，當(dāng)解碼速度很慢時(shí)(比如手機(jī)設(shè)備),就需要丟幀處理，是每?jī)蓭瑏G一幀數(shù)據(jù)，還是每3幀丟掉一幀數(shù)據(jù)，就需要根據(jù)延時(shí)顯示程度來(lái)計(jì)算丟幀的比率

havlenapetr最新的ffmpeg可以直接編譯通過(guò)，不過(guò)有個(gè)bug,就是播放完畢后，video_decoder線程不能退出，主要原因是阻塞在packet隊(duì)列的Queue->get函數(shù)里，這里處理邏輯需要考慮兩種情況：

1. AVPacket隊(duì)列里沒(méi)有音視頻幀數(shù)據(jù)時(shí)，解碼線程掛起進(jìn)入等待狀態(tài)，有新的AVPacket加入隊(duì)列時(shí)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(fā)現(xiàn)隊(duì)列空時(shí)直接退出
