ffmpeg - title to display throughout the video duration

Question

I have used the ffmpeg package to create a wmv file from gif (please see below). The title displays for a few seconds, then disappears. Is there a setting I can apply, in order to have the title appearing in the video throughout the duration?

ffmpeg -i Input.gif -s 300x300 -metadata title="Testing" Output.wmv

Following the suggestion by Maxito, I have modified the code to

ffmpeg -i Input.gif -vf drawtext="text='Text to write is this one,     overlaid':fontsize=20:fontcolor=red:x=100:y=100" Output_Text.wmv

The following error message was received:

[AVFilterGraph @ 0x100115cc0] No such filter: 'drawtext'
Error opening filters!

This is the version of ffmpeg I used on Mac 10.6.8. Is there a need to re-compile?

If by display you mean "in vlc" that's a client/playback thing, not an encoding thing, FWIW — rogerdpack, May 12 '15 at 14:33
Thanks, @rogerdpack. Is there a way to add a text to the video file that will appear in every frame using ffmpeg? — TTZ, May 12 '15 at 14:44

Looks like now that he's got the command right, the question is about the `AVFilterGraph` error. — Jason Sundram, Mar 25 '16 at 21:41

The error with AVFilterGraph and drawtext happens when your ffmpeg is compiled without libfreetype.

To generate images with text, you need to compile ffmpeg with libfreetype. The easiest way to do this is with Homebrew.

Assuming homebrew is already installed:

# If ffmpeg is already installed, you need to uninstall it.
brew uninstall ffmpeg

# you may very well want to specify other options (e.g. --with-faac)
brew install ffmpeg --with-freetype

Thanks for fixing that typo, @LordNeckbeard – Jason Sundram Mar 26 '16 at 20:57
This has to be taken as answer as the --libfreetype is the appropriate solution. – Vijay Kumar Kanta May 11 '16 at 09:50

You can download a ffmpeg binary for OS X if you don't want to compile. It contains support for libfreetype which is required for drawtext filter.

Users of other OS can get binaries via links on the FFmpeg Download page.
