Using FFmpeg with Android-NDK

Question

I want to use FFmpeg with Android-NDK and I am very basic in this section, I need some help and I research about this topic before on the net, but got no satisfactory solution.

1 - How can I use FFmpeg through Windows OS. (I do not want to use Ubuntu, please do not suggest.)

2 - How can I inset FFmpeg commands via NDK ?

Last notice : I using android-ndk-r7b and Cygwin .

Any suggestion would be appreciated.

Answer 1

From your question it is hard to tell what exactly you want/need... so here some general information:

• Using FFmpeg with Android
• Good starting point for FFmpeg on Android based on ndkr5
• Another good starting point for building FFmpeg for Android
• Helpful information to build FFmpeg for android see here , here and here
• Make sure that you use Windows paths instead of /cydrive... when doing ffmpeg/android/cygwin/windows dev

If you need further help please explain exactly what you want to achieve and what is not working...

UPDATE - as per comments:

To use ffmpeg via command line on Android you need to copy ffmpeg into your application's files directory and chmod 755 it using getRuntime.exec() then you can run ffmpeg with the following line for example:

Process p = Runtime.getRuntime().exec("/data/data/yourpackagename/files/ffmpeg -i infile.mp4 outfile.mp4")
