I'm trying to create a video using ffmpeg but I can't get the text watermark on the bottom right corner. It appears on the middle of the video. How should I change the following command?
-vf drawtext="fontfile=C\\:/Windows/Fonts/Arial.ttf: \
text='Stack Overflow': fontcolor=white: fontsize=24: box=1: boxcolor=black: \
x=(w-text_w)/2: y=(h-text_h-line_h)/2"
