IOException: Error running exec() Command, When calling FFmpeg method

i am trying to create a slide show mp4 using this ffmpeg method but i keep getting this IOException

Error running exec(). Command
when i click the button.

here is my call

ffmpegController = new FfmpegController(getTempDirectory(), new File(""));
ffmpegController.createSlideshowFromImagesAndAudio(slideFrames, getAudioPath(), getOutPath(), 500, mCallbackResponse);


Here is the source code of the small project.
Here is the apk

And here is my Error message

Error running exec(). Command: [ffmpeg, -y, -i, /storage/emulated/0/TestFFmpeg/frame1.png, /storage/emulated/0/TestFFmpeg/temp/image-000.jpg]

any help would be appreciated

Answer

you will need to copy ffmpeg binaries to res/raw folder as discussed here.

you may also need to build them first (dont just copy from above project), and make sure they can run on the device you are planning to test.
