Due to BSD license ,I opted OpenCV for extracting face from a video in a commercial product. For processing video need ffmpeg dll . I want to know : 1. what kind of license of opencv_ffmpeg.dll shipped in openCV package? 2. is this include GPL or non-free parts? 3. Is it safe to use ffmpeg.dll for a commercial application?
[see ffmpeg license]
Q: Is it perfectly alright to incorporate the whole FFmpeg core into my own commercial product?
A: You might have a problem here. There have been cases where companies have used FFmpeg in their products. These companies found out that once you start trying to make money from patented technologies, the owners of the patents will come after their licensing fees. Notably, MPEG LA is vigilant and diligent about collecting for MPEG-related technologies.
Addendum: Avoid using ffmpeg.dll at all costs. It is simply prohibited by its license, unless you take a redistribution license from them.
How about just building OpenCV without ffmpeg support and using any other video backend depending on which OS you are using like DSHOW, V4L, GSTREAMER, ... which can be used in any commercial packages.
