Question

所以开始吧...我试图使用ffmpeg将一组图像编译成Android上的视频。

我已经在线阅读了各种教程，并且已经能够为Android编译lib并且仍然需要项目运行。现在使用的回购可以在这里找到：https://github.com/Batterii/android-ffmpeg-x264

我对setttings.sh做了一些调整，只是为了纠正ndk的位置。除此之外，我按照说明进行操作，似乎完美无瑕。

之后，我将“Project”项目转换为Android stdio库模块。 Screenshot of android studio module

我没有得到任何编译错误，也没有得到任何运行时错误，或者我可以检测到的任何其他错误......在logcat上没什么......但我绝对没有得到任何视频out.mp4。在特定活动的onCreate中，我正在运行此代码：

Videokit vk = new Videokit();
vk.run(new String[]{"ffmpeg", "-r", "1/5", "-i", "%d.jpg", "-c:v", "libx264", "-r", "30", "-pix_fmt", "yuv420p", project.getProjectDirectory() + "/out.mp4"});

此命令取自此处的命令行示例： https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images

提前感谢所有花时间浏览这篇文章的人...我对此感到非常困惑，因为我找不到任何错误，也没有视频...... 感谢

原来它实际上并没有正确编译......但我找到了一些东西。这是项目的Eclipse版本的make文件

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE  := videokit
# These need to be in the right order
FFMPEG_LIBS := $(addprefix ffmpeg/, \
 libavdevice/libavdevice.a \
 libavformat/libavformat.a \
 libavfilter/libavfilter.a \
 libavcodec/libavcodec.a \
 libswscale/libswscale.a \
 libavutil/libavutil.a \
 libswresample/libswresample.a \
 libpostproc/libpostproc.a )
# ffmpeg uses its own deprecated functions liberally, so turn off that annoying noise
LOCAL_CFLAGS += -g -Iffmpeg -Ivideokit -Wno-deprecated-declarations 
LOCAL_LDLIBS += -llog -lz $(FFMPEG_LIBS) x264/libx264.a
LOCAL_SRC_FILES :=  ffmpeg/cmdutils.c ffmpeg/ffmpeg.c videokit/uk_co_halfninja_videokit_Videokit.c
include $(BUILD_SHARED_LIBRARY)

以下是gradle为我自动生成的make文件...感谢Android Studio ...

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE := videokit
LOCAL_CFLAGS := -g -Isrc/main/jni/ffmpeg -Isrc/main/jni/videokit -Wno-deprecated-declarations

最后，这是我的build.gradle

apply plugin: 'android'

        minSdkVersion 14

        }
    }

        jniLibs.srcDir 'src/main/libs'
        jni.srcDirs = ['src/main/jni/ffmpeg/cmdutils.c',
                       'src/main/jni/ffmpeg/ffmpeg.c',
                       'src/main/jni/videokit/com_t10_project_util_FfmpegHelper.c']
    }

    productFlavors {
        x86 {

            ndk {

            }
        }
        armv7 {

            ndk {
                abiFilter "armeabi-v7a"
            }
        }
        arm {

            ndk {

            }
        }
        fat
    }

    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:19.0.0'
    compile fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
}

正如您所看到的，我的build.gradle生成的内容非常接近原始内容......但不一样。当我尝试运行/编译它时，gradle吐出来

我现在已经搞乱了几个小时，而且几乎每次，我都在大吼大叫，因为它无法找到一些文件。我开始认为可能是因为我的LOCAL_LDLIBS与原来的顺序不一样......？我不完全确定......有没有其他人有任何想法......？

尝试使用FFMPEG for android。编译但仍无法正常工作
