libx264 encoder error in ffmpeg android build
26 décembre 2013, par kerim yucelRight now, I have a ffmeg build script which recognizes libx264 and compiles succesfully. I have also compiled x264 and obtained libx264.a library. Both ffmpeg and libx264 are built from source. I can build ffmpeg without libx264 succesfully as well. Below you may find my script which tries to build ffmpeg with libx264.

build_oneAbove script doesn't give me libx264.a in ffmpeg output builds.Several other scenarios are as follows.
If I enable x264 encoder, I get undefined reference errors to some variables in x264.c (in libavcodec).
If I enable shared in ffmpeg configure, I get an error which says it can't cd to my prefix directory (no permission issues by the way).I am using latest releases of ffmpeg and x264 (cloned the git today) and ndk 7. Ubuntu runs on VM, installed on Windows 7. For further details about my adventure of ffmpeg/x264 porting to Android, you may refer here.
What should I do to use libx264 with ffmpeg ? I kept on trying this script with different configurations, removed all ffmpeg x264 folders and reinstalled them, but to no avail.
Thanks a lot in advance.
EDIT
Below is my x264 build script. It builds fine, gives me the static library and the headers.export ARM_ROOT=/home/mehmet/Android_NDK_r7b

Yet another ffmpeg/libx264 issue
26 décembre 2013, par kerim yucelMy current situation is ; ffmpeg and libx264 has been compiled for Android, as shared and static libraries respectively. Since I have libx264.a and libffmpeg.so with me, only thing that remains is to link them and obtain a ffmpeg library that would allow me to proceed with my application. However, some questions remain unanswered. I am using Ubuntu with a virtual machine under Windows 7. I am using x264's last version, ffmpeg 0.10.4 release and NDK 7.
I have tried to adjust flags (extracf and extrald) in order to include libx264 to ffmpeg compilation process as well, however I keep failing. Below you may find my build script for ffmpeg and the errors I have encountered.
