I want to use openCV in a commercial product. This should basically be possible because of the BSD license. However, I also need ffmpeg for video decoding. ffmpeg can be compiled with either GPL or LGPL license, depending on which components are used. GPL would be a problem for my purpose.
Now my question is: what is the license of the prebuilt ffmpeg binary (opencv_ffmpeg.dll) shipped with openCV? Or, to put it another way, does it include any GPL or non-free parts? Is it safe to use it for a commercial application? I did not find any detailed information on this matter... I think building my own ffmpeg binary with the according flags could be an alternative, but it seems to be quite cumbersome so I would like to avoid this.
Thanks in advance for any help!
