Decoding Video Using Ffmpeg For Android

I tried to decode video using FFMpeg library from the sample examples available on internet, i figure it out with new version of ffmpeg, here is the code which I called from my cla

Solution 1:

Looking at the instruction causing problem...

$ rasm2 -a arm -d 4ff0e92d stclcs 0, cr15, [r9, #316]!

stc instruction documentation.

Searching for it, it might not be possible to do that from user space: Getting ILL_ILLOPC (illegal opcode) when trying to execute MRC or MCR instructions on Android

Then however this shouldn't be really your problem right? :)

Try to just print some logging messages in native (or at least do that before av_register_all()), don't add any other extra library, and see if you get that right.

Solution 2:

I think you built FFmpeg with compiler options not suitable for Android.

I would recommend to follow android-ffmpeg-tutorial, it has working example for FFmpeg on Android. It has reference to article about building FFmpeg for Android as well.

You also may want to have a look at much more advanced Android code with FFmpeg player AndroidFFmpeg, it works OK even in Genymotion emulator, I tested. Detailed instructions how to build, worked from the box.

Your code uses deprecated FFmpeg calls, code from the links above was updated for that matter.
