Generally it's H.264, but here's a chart for everything: http://en.wikipedia.org/wiki/YouTube#Quality_and_codecs

You used to be able to encode your videos within certain parameters to avoid a re-encode. You could also hex edit files to trick YouTube in allowing higher quality videos. However, now they just re-encode everything regardless. There might be new tricks you can try, but it is always changing. Either find somewhere better to put streaming videos or just leave a link for a HQ download for those who care about quality.

YouTube re-encodes everything due to an issue with VBV sizing. Nothing you can do about it currently. They also use relatively low bitrate, and IIRC a somewhat old build of x264 with their own custom crap rolled in. Don't quote me on that though.
