Convert youtube url to iframe embed code

[kiriku]

I've been trying to find a regex pattern to replace all youtube URLs in a string with the iframe embed code (C#). Obviously the video ID has to extracted. Here is the url patterns that should match:

• http://www.youtube.com/watch?v=bSiDLCf5u3s
• https://www.youtube.com/watch?v=bSiDLCf5u3s
• www.youtube.com/watch?v=bSiDLCf5u3s
• youtu.be/bSiDLCf5u3s
• http://www.youtube.com/watch?feature=player_embedded&v=bSiDLCf5u3s
• www.youtube.com/watch?feature=player_embedded&v=bSiDLCf5u3s

all possible urls should be replaced with:\[code\]<iframe title='YouTube video player' width='480' height='390' src='http://www.youtube.com/embed/VIDEO_ID_EXTRACTED' frameborder='0' allowfullscreen='1'></iframe>\[/code\]Can someone please point me to a right direction.Thank you in advance
