Yes, unless VLC fails to proxy everything to the socks proxy

I made a quick test (socks 127.0.0.1:9150 with TBB OP), it's working but 
indeed VLC fails to proxy everything, we see direct http requests to yt, 
probably a VLC bug.

"tons of tracking stuff" is an euphemism in the case of yt, the 
audio/video will play if yt receives what it expects after the yt 
"handshake" (get_video_info), and this looks like this:

GET 
/videoplayback?ms=au&itag=22&mv=m&ratebypass=yes&source=youtube&key=yt5&id=o-AFIyvZzsT98MLcoQTXGmoPAdVWLv5JNhzKGhYDSX3jkz&sparams=id%2Cip%2Cipbits%2Citag%2Cratebypass%2Csource%2Cupn%2Cexpire&expire=1401228751&upn=v80J3yeuBUg&fexp=935503%2C945043%2C934804%2C929305%2C914048%2C919118%2C945528%2C913434%2C923341&sver=3&signature=9189C9550B66A7A106E42F0FF7DDB92095F7A748.157A1E1BBEB1396D3216155561DE1A3E6E8C4204&mt=1401203257&ip=aa.bb.cc.dd&mws=yes&ipbits=0 
HTTP/1.1

The ip address will not be yours but other params have to be analyzed.

Conclusion: do not use VLC as it is or wait for FF to have implemented 
the MSE API, according to google yt uses MSE for most HTML5 playbacks
