Inclusion of FFmpeg Libraries

[Alexandertyler-zz]

Hi, I compiled ffmpeg on linux and tried to include it into the project but it started throwing errors on the ffmpeg-jni.c file.

Here is the output:
/home/alex/Cs/youtube-yt-watchme-bca6784/app/src/main/jni/ffmpeg-jni.c

This is weird because in yt-watchme/app/src/main/jni/Android.mk already defined C99 mode.

You need to build the ffmpeg with the provided JNI code and Android.mk
Also you need to cross-compile it as in: https://trac.ffmpeg.org/wiki/CompilationGuide/Android

Hello,

I had exactly the same problem.
I have solved it this way: Do not try to generate the apk with android studio because it will not use the android.mk provided. Instead open a command line shell, go to the jni folder and enter the following command to build the native code:
$ ndk-build

With this, you will go further, but with this I am stuck with the following problem:
libavutil/common.h:83:23: fatal error: config.h: No such file or directory

And actually in this file, I have

ifdef HAVE_AV_CONFIG_H
include "config.h"
include "intmath.h"
endif

Is there someone else who had this problem?

Thank you!

Hi,
config.h is located in the ffmpeg source folder, you should copy to your "third_party/include" folder.
And intmath.h and other headers you may need could be found in libavutil, under ffmpeg source folder.

I don't remember the specific headers needed but all of them are in libavutil.

I have the same problem. =(

I have tried to build with all FFmpeg sources at Compilation Guide but in all cases got some error. Can anyone that had a successful FFmpeg inclusion and app construction help us? I will keep trying and with any success I will post here. Thanks in advance!

Hi, Guys
I'm trying to use the watch but I had many difficulties
With much efforts I compiled it but some .so file is still missing after compile
And when I click start screaming, the camera screen is displayed and app crashed after 2 or 3 seconds and no recording on event
Please give me an advice
Everything will be really appreciated
