I’m going to guess … and, mind you, this is only a guess! But I did a bit of searching and here’s what I’m thinking: the concert was in Munich in 2005 (so it says). Searching on that information, it appears that the orchestra is the Münchner Rundfunkorchester (Munich Radio Orchestra). So I went to the orchestra roster page, and from there to the page where oboists are listed. The principal is a man, as is the third player listed, so I’m just guessing that perhaps this is the second player, Yeon-Hee Kwak. Now of course all of this is merely my guesswork, so I could easily be wrong.
But the searching was fun! 
Update: doing more searching, I’m not certain this was in 2005; some search results came up with 2004. Just FYI.
(I do wonder about YouTube and copyright issues; will they eventually be sued? I believe there is supposed to be a DVD of this concert … IF it’s the concert in question.)
