Answer 1

Why are you ever want to avoid using something that designed especially for the task? Anyway there is a plenty of commercial and open-source tools/libraries that can help you with this, and some of them probably have API's or bindings for what you working with...

It's possible with ImageMagick using frame extraction with convert command:

convert movie.mpg[0]

You can also create animated GIF from range of frames:

convert movie.avi[0,100,200] -background white -compose darken -flatten out.gif

OR

convert movie.avi[100-200] -background white -compose darken -flatten out.gif

Answer 2

Bitmap bm = MediaStore.Video.Thumbnails.getThumbnail(getContentResolver(), 1, 1, null);
ImageView iv = (ImageView) findViewById(R.id.ImageView01);
iv.setImageBitmap(bm);
