You want to build an app using ffmpeglib, is that right ?
If so, are you using clickable ?

With clickable, you can provide the dependencies-target to use an external lib :

Did I get it wrong?
是不是我哪里理解错了?

@AppLee Hello! I have an application based on FFMPEG. I want to compile it to uborts and rely on ffmpeg lib. I can't root to install ffmpeg lib

@wangqinfeng
You cannot add the lib to the system, it's locked for safety reasons.
(Well you can but shouldn't)

You need to embed the dependencies you're using within your click package.
If you're using clickable, it takes care of it for you using the params I gave you in the clickable.json

How do you build your click ?

build ffmpeg_lib

bash>:docker run -v home/xxxx/netplay:/home/xxxx/netplay -w home/xxxx/netplay/libs/ffmpeg_source -u 1000 -e HOME=/tmp -i -t clickable/ubuntu-sdk:16.04-armhf

bash:>
./configure --target-os=linux --arch=arm64 --disable-asm --disable-x86asm --enable-cross-compile --cc=/usr/bin/arm-linux-gnueabihf-gcc --prefix=/home/xxxx/netplay/libs/ffmpeg_source/build --disable-ffmpeg --disable-ffplay --disable-ffprobe

bash:>make -j 8

vim CMakLIst.txt:

bash:> clickable clean build click-build launch logs

Finally, it can be used! build ffmpeg_lib to ubports!
