+Dear Seung-Woo,
+I've been interested in using and extending OBS.  In browsing the
+source code I found your excellent contribution [1].  Given that I use
+OBS with Intel QSV on a daily basis, I was wondering if the comments
+in the headers such as "INTEL CORPORATION PROPRIETARY INFORMATION" and
+the reference to the non-disclosure agreement were included in error?

+
+Hi Aidan,
+
+
+
+Yes, I work with OBS and have contributed a few changes (user cmlin2) in the last year. I think your question is more about the code that Seung-Woo contributed, correct?
+
+
+
+Seung-Woo, was the QSV contribution you made still under NDA?
+
+
+
+Thanks,
+
+Christine

+Aidan,
+
+
+
+This is a legal question. Christine is finding the right contact to address the matter.

+
+Hi Aidan,
+
+
+
+We got through to Legal and it looks like the NDA clause that Seung-Woo added 5 years ago to the code he added to OBS doesn’t apply to open source code once it’s been accepted by the community. You can remove it for your modifications.
+
+
+
+Thanks,
+
+Christine
