now I want to make sure it works and plays appropriately on andoid and IOS, could anyone tell me how to test this file on android and IOS ?

How to build FFMPEG lib with android ndk

27 janvier 2017, par S. Le Galloudec

I introduce my problem : I’m a student working on a project asked by a company to my school.
My part is to develop an android application (i have to use c++) who can make an authentication, ask to an api wich camera the client can watch, then display in real time the stream of the IP camera (using RTSP protocol)

To be honnest i’m pretty lost. I’ve found the library FFMPEG, wich looks like useful to my project. If i got it right, the library can display a stream from a camera. So i built the library for my project, and then i tried to include it in my program.

I did it the same way i did to include the library curl that i already use.

But when i try to run my program, i got this message :

FAILURE : Build failed with an exception.

What went wrong :
Execution failed for task ’:app:externalNativeBuildDebug’.
Build command failed.
Error while executing ’/local/Android/Sdk/cmake/3.6.3155560/bin/cmake’ with arguments —build /local/Bureau/Projet2/videosurveillance/Application_Android/App_Android/app/.externalNativeBuild/cmake/debug/x86 —target lecteur

Try :
Run with —stacktrace option to get the stack trace. Run with —info or —debug option to get more log output.

And i know that the problem comes from my cmakelist, or from my tree. But i don’t see the mistake, so if you could help me. Here is my cmakelist :

If you want to understand how i made my cmake, and what looks like my program you can check here : https://github.com/samylegalloudec/android-ndk-ffmepg

Hope i was clear

Best regards

Edit n°1 :

I think i’ve made a mistake in my cmakelist.txt so i fixed it (i guess) this way :
