ffmpeg text watermark bottom left

Question

I have found out how ffmpeg can add image watermark at the bottom left of a video

ffmpeg -i "C:\test.mp4" -i "C:\test\watermark.png" -filter_complex "overlay=10:main_h-overlay_h-10" "C:\test-watermark.mp4"

but I am looking for a way to add text (white, 12px text, with black shadow to make the text readable) instead of an image. Can somebody help me?

Use the drawtext filter.

ffmpeg -i "C:\test.mp4"
 -vf "drawtext=text='Place text here':x=10:y=H-th-10:
               fontfile=/path/to/font.ttf:fontsize=12:fontcolor=white:
               shadowcolor=black:shadowx=5:shadowy=5"
"C:\test-watermark.mp4"
