Tried
ffmpeg -f android_camera -i 0 -vcodec flv1 -f flv /sdcard/capture.flv
and
ffmpeg -f android_camera -i 1 -vcodec flv1 -f flv /sdcard/capture.flv
and
ffmpeg -f android_camera -i - -vcodec flv1 -f flv /sdcard/capture.flv
Mistake
Failed to allocate memory for camera_id
Failed to open camera
Failed to open android_camera
0: Generic error in an external library
...
pipe: Generic error in an external library
If so
ffmpeg -f android_camera -map 0 -vcodec flv1 -f flv /sdcard/capture.flv
Mistake
Invalid input file index: 0.
