Hi,
I need help with filter_complex and drawtext.
drawtext on aspect 4:3 are correct but drawtext on aspect 16:9 are
stretched.
thx for help ...
ffmpeg -i C:\ffmpeg\test-4.3.mp4 -filter_complex
"drawtext=fontfile=/Windows/Fonts/arial.ttf:text='0123456789':fontsize=20:fontcolor=white:x=10:y=10"
-aspect 4/3 -map 0 -map -0:d -vcodec libx264 -acodec aac -y
