Comment (by beloko):
Shared the "enable" option filters with others is a nice goal, FFmpeg can
solve many use cases.
Ex: With "draw" option, I can make a text readable on any high resolution
video file in just one FFmpeg command line. Otherwise, I have to detect
the input video resolution width before call a specific FFmpeg command for
each width.
I prefer switch between different font sizes than having an auto-scale
text I can't size properly.
For now, I built a new FFmpeg binary by merging your patch. "Drawtext"
error messages are left after the command line, but the text content
doesn't appear on the output video file.
