Ask HN: video manipulation libraries?

4 pointsby hernan7almost 15 years ago

Anybody has any good/bad experiences with libraries that do programmatic video manipulation? Especially something that can be driven by a scripting language. Free/inexpensive if possible...<p>Thanks in advance!

Like what exactly?<p>I've found ffmpeg and OPENrtsp both pretty easy to setup and use for basic video conversion and simple stuff. Not sure though if you're just trying to convert to a different format, add watermarks, detect scene activity, or something different.

For anything related to computer vision, OpenCV: <a href="http://opencv.willowgarage.com/wiki" rel="nofollow">http://opencv.willowgarage.com/wiki</a><p>It also includes a bunch of useful generic image processing routines like scaling, convolutions, etc.
