Hello anony,

For Intel® Distribution of OpenVINO™ toolkit version 2021.4 we have the following under LGPL license:

1.    FFMPEG in OPENCV folder

Referring to:

<install_root>/opencv/third-party-programs.txt and <install_root>/opencv/ffmpeg-download.ps1

FFMPEG wrappers for Windows are not supplied with the distribution. If you need to read and write video files on Windows via FFMPEG, please download the files using the provided script.

Note that these wrappers are subjects to LGPL license. The full source code is available at the same repository on GitHub:

https://github.com/opencv/opencv_3rdparty/tree/ffmpeg/master_<timestamp>_src

Example: https://github.com/opencv/opencv_3rdparty/tree/ffmpeg/master_20211005_src

2.     GStreamer

GStreamer is an open-source framework licensed under LGPL.

See https://gstreamer.freedesktop.org/documentation/frequently-asked-questions/licensing.html?gi-language=c. 

You are solely responsible for determining if your use of GStreamer requires any additional licenses. Intel is not responsible for obtaining any such licenses, nor liable for any licensing fees due, in connection with your use of GStreamer.

Thank you very much.

I checked about FFMPEG and found that in "\opencv\etc\licenses\ffmpeg-readme.txt" it says "If LGPL/GPL software can not be supplied with your OpenCV-based product, simply exclude opencv_videoio_ffmpeg*.dll".
I am assuming that since the program I am using excludes the DLL, it does not violate the GPL, is that correct?
Also, how can I determine if I am using or not using gsstreamer?
I am assuming that the configuration I provided in my link does not include gsstreamer, is that correct?

Hello anony,

We’ve got replies for both of your questions:

(1) Yes, you don't violate GPL license since you didn't use opencv_videoio_ffmpeg*.dll in your program.

(2) Referring to the list of dlls in the following message: No, you don’t use GStreamer in this list of dlls.
