MP4 H.264 - Flash Media Server

Greetings all

I have a stack of MP4 H.264 videos that I have been asked to create a flash player for. This flash player will be put up online to view. So my question is the following…

Do I need Flash Media Server to stream mp4?

Also, if I convert an MP4 to flv (in order to import into flash in the usual way) will the quality be affected?

As ever, any help would be really appreciated.
