Comment:

 Replying to [comment:7 beloko]:
 > Shared the "enable" option filters with others is a nice goal, FFmpeg
 can solve many use cases.

 Note that it's not a "goal", it actually is the case:
 {{{
 ☭ ./ffmpeg -v error -filters|grep -c '^ T'
 49
 }}}

 > 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.

 text I can't size properly.

 Sorry, I have no idea what you are talking about here, but I'm probably
 very tired.

 > 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 in the output video file.

 That patch is now applied. I don't like that solution much because I
 believe we should add a "display-the-text-only-if-it-fits-in" in drawtext,
 but since it's somehow a regression, I applied that version.

 What error messages are you talking about?
