Best Language for dynamically watermarking videos?

Question

I'm looking to dynamically add watermarks to a video on a website. What, in your opinion, is the best language and library to do so?

Answer 1

You can do this using ffmpeg (from command line or using one of its API such as ffmpeg-php) with the watermark or drawtext vhook component, depending of what you want to add (a logo or a simple text).

Answer 2

I believe you have a couple choices.

Both Flash and Silverlight should allow you to create a separate layer and have your watermark displayed.

I'm not sure if there is a way to do this with mpeg/qt videos.

Answer 3

Of course, http://ffmpeg-php.sourceforge.net/ is better to dynamically add watermarks to a video on your website.
