FFMPEG 1.0 ANDROID NDK R8B

我試圖用android ndk r8b編譯ffmpeg的最後一個版本，但我總是有錯誤，我不知道如何解決它們。我正在閱讀本教程http://www.roman10.net/how-to-build-ffmpeg-for-android/，但該腳本不適用於我的環境，我正在使用： -Ubuntu 12.04 LTS。 -Intel Core i7。 -Android ndk r8b 最新版本ffmeg（1.0）FFMPEG 1.0 ANDROID NDK R8B

基本上我想編碼從一種格式的電影到其他。

這是我使用的腳本：

NDK=../android-ndk-r8b 
PLATFORM=$NDK/platforms/android-8/arch-arm/ 
PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86

這是終端結果

[email protected]:~/Descargas/ffmpeg$ bash build_android.sh 
/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 
[email protected] 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.

的工作，我有找到一個方法來編譯多小時後：

1）在包含android-ndk和ffmpeg的文件夾中給予權限"chmod 777 ./* -R"在我的情況下（Be確定使用'./ '而不是'/'！）
2）安裝我需要的東西在我的環境中。
3）這是我的新.sh文件
