早在去年九月份时，写过一篇《手把手图文并茂教你用Android Studio编译FFmpeg库并移植》，今天用去年编译好的3.1.3的ffmpeg，进行在Android平台上解码直播流。看下Agenda:

  • 环境
  • Java代码
  • ndk代码
  • 解码运行

环境：

  • Mac OX
  • Android Studio 2.2
  • android-ndk-r10e
  • FFmpeg 3.1.3

Android Studio + NDK的环境配置，由于很简单，这里就不再脑补了。

建立一个工程

写Java代码：

NativePlayer:

生成头文件：javah -d jni com.hejunlin.ffmpegdecoder.NativePlayer

这里写图片描述

拷贝ffmpeg3.1.3中android目录下的include文件，共5个子文件夹，以及对应的5个so，到prebuilt下，include,prebuilt这个可以自己建立一个folder。

这里写图片描述

然后写make文件：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := avcodec
LOCAL_SRC_FILES := prebuilt/libavcodec-57.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := avformat
LOCAL_SRC_FILES := prebuilt/libavformat-57.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := avutil
LOCAL_SRC_FILES := prebuilt/libavutil-55.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := swresample
LOCAL_SRC_FILES := prebuilt/libswresample-2.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := swscale
LOCAL_SRC_FILES := prebuilt/libswscale-4.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_SRC_FILES := yuiopffmpeg.c
LOCAL_LDLIBS += -llog -lz -landroid
LOCAL_MODULE := yuiopffmpeg
LOCAL_C_INCLUDES += $(LOCAL_PATH)/include

LOCAL_SHARED_LIBRARIES:= avcodec avformat avutil swresample swscale

include $(BUILD_SHARED_LIBRARY)

这里写图片描述

同时写下Application.mk，这个主要是用于编译不同平台的库，对应内容如下,由于引用了native_window.h，要加上一句APP_PLATFORM := android-10 ：

APP_ABI := armeabi armeabi-v7a x86
APP_PLATFORM := android-10


这里写图片描述

接下来，最主要就是写jni相关代码，yuiopffmpeg.c这个文件，之前生成的那个头文件，拷贝里面那个方法名，贴到这里来

    }
    // Determine required buffer size and allocate buffer
    // buffer中数据就是用于渲染的,且格式为RGBA
    int numBytes=av_image_get_buffer_size(AV_PIX_FMT_RGBA, pCodecCtx->width, pCodecCtx->height, 1);
    uint8_t * buffer=(uint8_t *)av_malloc(numBytes*sizeof(uint8_t));
    av_image_fill_arrays(pFrameRGBA->data, pFrameRGBA->linesize, buffer, AV_PIX_FMT_RGBA,
                         pCodecCtx->width, pCodecCtx->height, 1);
    // 由于解码出来的帧格式不是RGBA的,在渲染之前需要进行格式转换
    struct SwsContext *sws_ctx = sws_getContext(pCodecCtx->width,

                             AV_PIX_FMT_RGBA,
                             SWS_BILINEAR,
                             NULL,
                             NULL,
                             NULL);
    int frameFinished;
    AVPacket packet;
    while(av_read_frame(pFormatCtx, &packet)>=0) {
        // Is this a packet from the video stream?
        if(packet.stream_index==videoStream) {
            // Decode video frame
            avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &packet);
            // 并不是decode一次就可解码出一帧
            if (frameFinished) {
                // lock native window buffer
                ANativeWindow_lock(nativeWindow, &windowBuffer, 0);
                // 格式转换
                sws_scale(sws_ctx, (uint8_t const * const *)pFrame->data,
                          pFrame->linesize, 0, pCodecCtx->height,
                          pFrameRGBA->data, pFrameRGBA->linesize);
                // 获取stride
                uint8_t * dst = windowBuffer.bits;
                int dstStride = windowBuffer.stride * 4;
                uint8_t * src = (uint8_t*) (pFrameRGBA->data[0]);
                int srcStride = pFrameRGBA->linesize[0];
                // 由于window的stride和帧的stride不同,因此需要逐行复制
                int h;
                for (h = 0; h < videoHeight; h++) {
                    memcpy(dst + h * dstStride, src + h * srcStride, srcStride);
                }
                ANativeWindow_unlockAndPost(nativeWindow);
            }
        }
        av_packet_unref(&packet);
    }
    av_free(buffer);
    av_free(pFrameRGBA);
    // Free the YUV frame
    av_free(pFrame);
    // Close the codecs
    avcodec_close(pCodecCtx);
    // Close the video file
    avformat_close_input(&pFormatCtx);
    return 0;
}

这时就可以执行编译了，完成就能发现会多一个so,就是那个libyuiopffmpeg.so，这就是我编译出来的。
这里写图片描述

这时候，在Android studio下的main目录下，建立一个jniLibs，把刚刚那个so拷贝到这里就行了，就只要这个so就可以了。不同平台，如arm,x86,这些文件夹名字不能随便改。记得还要加如下配置，在build.gradle中。本文出自逆流的鱼yuiop：http://blog.csdn.net/hejjunlin/article/details/59225373

接下来就运行这个工程，运行时，又有问题。

这里写图片描述

然后发现原来没有加网络权限，在AndroidManifest.xml中，加上

 <uses-permission android:name="android.permission.INTERNET" />

最后，就可以运行了，效果图，如下：
