I have tried to compile the last version of ffmpeg with the android ndk r8b, but i always have errors and i dont know how to solve them. I am reading this tutorial http://www.roman10.net/how-to-build-ffmpeg-for-android/ but the script doesnt work with my environment, i am using this:
-Ubuntu 12.04 LTS.
-Intel Core i7.
-Android ndk r8b
-Last version ffmeg (1.0)
Basically i want to encode films from one format to other.
And that is the script that i am using:
NDK=../android-ndk-r8b
PLATFORM=$NDK/platforms/android-8/arch-arm/
PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86
function build_r8b
{

/android-ndk-r8b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc is unable to create an executable file.
C compiler test failed.
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
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

After many hour of work i have find one way to compile it:
1) give permissions
"chmod 777 ./* -R"in the folder that contains android-ndk and ffmpeg in my case (Be sure to use ‘./‘ and not ‘/‘!)2) install things that i need in my environment.
3) this is my new
.shfile
