Video: 10G switches

I am capacity planning for 8-10K streams of video (150-300Kbps) through a Nexus 7000 or an EX 8200 pair. The same infrastructure will be carrying quite a few audio minutes as well. Does someone have experience with either of these platforms with this scale of audio/video ?

Looking for some practical advice about buffers/specific line cards/things to avoid etc. not for the usual teal/blue debate.
