IMO, Yes. The bubbles look far to 'stringy' to be yeast. I've only had infections in my ciders but this looks similar to the white slick I had rather than your typical porridge-y krausen yeast bubbles.
Let some other folks weigh in before you do anything drastic.
Often times you can rack out from under it, hit it campden/K-meta and then repitch. There's also the bold option of letting it sit for a while and seeing how it turns out.
