How can i build an axecutable ffmpeg binary for android instead of .so file?

NDK 是14b

./init-config default
./compile-android-ffmpeg.sh all

下面是armv7报的错

怎么编译成.so？

./init-config-ffmpeg all 不存在

init-config.sh default|lite|min|litehevc|mp3|mp4"

Hi
This is just a query

As per the new android playstore policy we need to make the native code support 64 bit. is this library support 64 bit?

I found your repository in bilibili/ijkplayer#4558

I was able to compile FFMPEG libs by following the instructions in README_FFMPEG.md but I can't integrate with ijkplayer.
I copied the directories and files generated in /product and pasted in /ijkplayer/android/contrib/build/ but it didn't work. The script /ijkplayer/android/compile-ijk.sh don't run.

Do you have any tip? Could you please help me?
Thanks!

I see the wrong code here.

Revision : 0d82357
File : contrib/src/ffmpeg/rules/Makefile Line 178
F FMPEGCONF += --disable-mmx --disable-mmxext --disable-inline-asm

Should we remove the char "F" in the beginning ?

我看代码很像从ijkplayer里面抽取出来的， 如果是的话最好注明一下来源和license。

Hi bro.

I wanna to start with FFMPEG but it is really hard to find the good documents for newbie like me.
My idea in the beginning is just to write a video player to play a mp4 file by JNI code.

Could you help me to gain knowledge or give me lib/tutorial to start ?

ndk18 去掉了gcc, 如何在shell脚本里指定clang. 需要如何配置，麻烦您指点一下。

I have download the newest ffmpeg and openssl, then add ffmpeg-armv7a 、openssl-armv7a to dir android manually on my Mac(NDK19). after that, run:

./init-config-ffmpeg.sh lite
./compile-android-openssl.sh armv7a

everything work(libssl.a is in the dir : /build/openssl-armv7a/output/lib),but when :

./compile-android-ffmpeg.sh armv7a

it goes error , nothing *.so generate in dir : /build/ffmpeg-armv7a/output/lib :

ERROR: openssl not found

The same operation on my ubuntu(NDK19) work well .

ffmpeg ffbuild config.log

Thx .

Hello,
I am using cygwin on Windows 10 machine and have Android Studio installed.

Copied your repository .

cd ~/libs-build-tool

export ANDROID_HOME=/cygdrive/C/Users/kulka/AppData/Local/Android/Sdk

Then ran following command:->

$ ./android.sh --lib-ffmpeg --ffmpeg-config-min --arch-armeabi-v7a

INFO: Unknown option "".
See ./android.sh --help for available options.

When I checked the code, looks like --lib option is not being handled in ./android/main.sh file.

Any help will be appreciated.

Thanks
Rajiv

1、生成的libsffmpeg.so 会不会因为配置项变小？（这个我会去尝试，如果你有经验可以节约我很多时间）

我目前的功能只需要录制保存（主要是编码），用lite会打出17.5m感觉有些接受不了。

2、看了下打印的日志，兼容到r19的方式应该是通过生成clang3.6和Android-21 的独立工具链吧？

感觉这样和希望的使用最新的版本，比如Android-28不太符合。

3、编译的过程中充斥这个警告

warning: unknown warning option '-Wno-psabi' [-Wunknown-warning-option]
warning: unknown warning option '-Wno-bool-operation'; did you mean '-Wno-bool-conversion'? [-Wunknown-warning-option

ps.因为我也是刚接触，所以目的可能比较理想还请见谅。
如果能解答，给下解决方法就好了，如果可以更新库就更好了，谢谢

[*] configurate ffmpeg

GNU assembler not found, install/update gas-preprocessor

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

工具链的路径怎么是在当前项目路径下?

支持iOS吗?
顺便问一下 看到说需要 python 是python2.x还是python3.x

在window10的linux子系统下执行编译的时候会报错（openssl 和ffmpeg编译都没有结果）:

[*] Finished
我的确是在d盘python37下面有windows的python.

另外：
初始化FFmpeg配置模块：中的default模式是相对于
https://blog.csdn.net/biezhihua/article/details/86186420
这个文档中的all配置吗？
如果你需要更多的编码和格式
./init-config-ffmpeg all

环境：
win10 1903 with kali subliunx.

看着和ijkplayer的那一套编译差不多的. 有考虑过用CMakeList组织么? 这样更方便源码引入FFmpeg到现有项目中?
