One Answer:
If you want to see only the traffic related to you tube, you just need to apply an ip filter But if you want something more accurate you might want to include some of this other filters answered 18 Aug '11, 14:42  sfrj |
That won't mean he only captures packets to or from YouTube; it captures all packets and then filters them out later.
Unfortunately, it's really hard to have a capture filter for YouTube - I just played a video, and it was sent over HTTP from a host named "o-o.preferred.nuq04s10.v2.lscache2.c.youtube.com", so it's probably very hard to predict what host will send the video. I'd say "capture without a filter and look for YouTube traffic".
