something like this.

but it still does not work from console

configure:

./configure --enable-jni --enable-mediacodec --enable-neon
--target-os=android --disable-outdevs --disable-indev=xcbgrab

run:

./ffmpeg  -pixel_format nv12 -loglevel trace -f android_camera
-camera_index 1 -input_queue_size 5 -video_size 1280x720 -i 0:0 -c:v
libx264 -g 30 -b:v 980k -r 30 -s 1280x720 -b:a 28k 11test.mp4

it just sits here doing nothing, I guess waiting for application window?
