ffmpeg-commands-executor-library's Introduction

This is AS version
Eclipse version, please refer to Old Eclipse Version

ffmpeg-commands-executor-library

execute ffmpeg commands as a shared librar, you can try example.apk
[Note]: This library may not support all the codecs you want, for example, h264.

Usage

add dependency in your build.gradle

dependencies {
    compile 'cn.dxjia:ffmpegexecutor:0.1.7'
}

import package

import cn.dxjia.ffmpeg.library.FFmpegNativeHelper;

run command

FFmpegNativeHelper.runCommand("ffmpeg -version");

NOTE:

now, runCommand() will return some strings as result, not very friendly;
this library modified some ffmpeg source code, invasion is relatively strong.

Compile library or example by yourself

If you want to compile this library by yourself, you can do that as follow steps.

Step 1

Build jni manually

Linux or Ubuntu

cd library/jni
chmod a+x build.sh
. build.sh

Windows

Make sure you have add your NDK path to your PC Enviroment.
Open a CMD terminal

cd library\jni
build.cmd

Step 2

Android Studio -> Open Existing Project

Step 3

modify code & build project

NOTE: Every time you changed the jni source code, you need to build it manually before building the project from Android Studio.

Any issues and PRs are welcome.

UnsatisfiedLinkError

Caused by: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.archery.archery.tv-2/base.apk"],nativeLibraryDirectories=[/data/app/com.archery.archery.tv-2/lib/arm, /cust/lib, /vendor/lib, /system/lib]]] couldn't find "libavutil-54.so"
这是什么原因，会是和Ijkplayer混用导致的库冲突吗

为什么运行命令找不到？h264??

ffmpeg -i K:/ffmpegtest/20160614104833_10.MP4 -vcodec h264 -s 320*240 -an -f mp4 K:/ffmpegtest/result_m4v.MP4

运行这段命令找不到h264？？还有好多命令都用吧了，但是widows版本的没问题，是不是少编译了东西

Run a same transfer command two times will bring APP to crash

my step：

recorder video profile :
mProfile = CamcorderProfile.get(CamcorderProfile.QUALITY_480P);
mProfile.fileFormat = MediaRecorder.OutputFormat.MPEG_4;
mProfile.videoCodec = MediaRecorder.VideoEncoder.H264;
mProfile.audioCodec = MediaRecorder.AudioEncoder.AAC;
mProfile.videoFrameRate = 15;
mProfile.videoBitRate = 1200000;
create video file : /sdcard/demo.mp4
run ffmpeg -y -i /sdcard/demo.mp4 -vf crop=iw/3:ih:0:0 -strict -2 /sdcard/demo2.mp4

It's perfect for the first time. and not kill app, do the second . the app is dead.

根据runCommand返回值判断命令是否执行成功

FFmpegNativeHelper.runCommand执行成功的返回值是什么？谢谢！

恳请提供64位的库

现在手机基本都是64位的了，32位的放在64位的arm-64，运行就崩溃

这样子的话，项目会不会比so文件大？

ffmpeg报“Out of memory”错误

你好，我用ffmpeg处理视频压缩。
命令如下："ffmpeg -y -i " + url + " -strict experimental -r 20 -vcodec mpeg4 -b 10000 -s 640*480 /storage/emulated/0/abc.mp4"
第一次运行压缩成功，但是第二次运行就会报错，错误如下：
“ffmpeg-jni: [audio format for output stream 0:1 @ 0x9bef4960] Query format failed for 'audio format for output stream 0:1': Out of memory”
必须重启应用才可以再次压缩，然而也只能执行一次，第二次就报错了。

Text relocations on API >= 23

When compiling against API 23+, text relocations are no longer supported. You might recompile lib without relocations.

java.lang.UnsatisfiedLinkError: dlopen failed: /data/app//lib/x86/libavcodec-56.so: has text relocations

http://stackoverflow.com/questions/32346402/libavcodec-so-has-text-relocations

Win10下面直接使用ndk-build编译之后运行出错

编译之后将so文件放入AS中，目录如下:

出错信息如下：

NDK版本为android-ndk-r10e

请教

大神，step2 和step3能否写清楚点？我按照你另一个例子编译出来so库了，但是卡在step2和step3。就是如何将ffmpeg.c改为FFmpegNativeHelper.c那步，以及ndk-build的时候会提示h文件缺失，需要引入include外的ffmpeg源码中的h文件那个步骤。

第二次执行视频转码命令时报错

采用gradle依赖（compile 'cn.dxjia:ffmpegexecutor:0.1.7'）
同一个视频转码命令（"ffmpeg -i /sdcard/Media/VID_1149.mp4 -r 30 -f gif /sdcard/1149_20.gif"）第一次正常执行，第二次报错，错误信息如下：
A/ffmpeg-jni: Option threads not found.
E/ffmpeg-jni: Error, assert_avoptions

不能

FFmpegNativeHelper.c 该文件是怎么生成的呢，我怎么生成的文件都带有包名啊

我是studio 项目，作者给说说在哪个目录执行命令啊生成啊

Please add support for x86_64 and arm64

demo运行视频加水印的命令失败了

能不能同时执行两条命令行

需要同时推两路流，能不能实现

编译出错

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/cn.dxjia.ffmpegexecutor-1/base.apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]]] couldn't find "libavutil-54.so"

java.lang.UnsatisfiedLinkError

compile 'cn.dxjia:ffmpegexecutor:0.1.7' but i'm get error that
java.lang.UnsatisfiedLinkError:dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.jlx.resumeshow-1/base.apk"],nativeLibraryDirectories=[/data/app/com.jlx.resumeshow-1/lib/arm, /data/app/com.jlx.resumeshow-1/base.apk!/lib/armeabi-v7a, /vendor/lib, /system/lib]]] couldn't find "libffmpegjni.so" how do i get this ".so"?

x264

如何支持x264的类库

关于例子中命令行的使用问题

您好，
按照您readme的说明，完成了ffmpeg的编译工作，也成功运行了您的例子。但是例子中的命令行，在cmdutils.c中没找到你实现方法的命令行说明。
我要使用其他命令行，该如何操作，或者说阅读哪些文件，能知道命令行的使用方法。
谢谢您，对代码的开源，对我有很大的帮助。
希望您能给我解答。

如何使用单一的libffmpeg.so文件进行链接呢？

我之前按照项目需求单独生成了libffmpeg.so，把你Android.mk里那一堆prebuild so的地方改成了
include $(CLEAR_VARS) LOCAL_MODULE := ffmpeg LOCAL_SRC_FILES := prebuilt/armeabi/libffmpeg.so include $(PREBUILT_SHARED_LIBRARY)
其他不变，缺失的头文件也从源码里面拷到include里面了。
最后ndk-build的时候出现了一堆undefined引用

请问这个能如何解决呢？还是说我编译ffmpeg configure的时候必须选enable-shared？
