Youtube player iframe embed not working for my channel

I am trying to add a youtube player for my channel using iframe on my website.

I picked up code from here

The channel is - http://ift.tt/1Ht1yL7

I have used the channel id - UCYPhPtoN64fI2hfge6Iw_gQ in the below html code snippet on my website.

<iframe id="ytplayer" type="text/html" width="400" height="225" src="//www.youtube.com/embed/?listType=user_uploads&list=UCYPhPtoN64fI2hfge6Iw_gQ" frameborder="0" allowfullscreen></iframe>

I get error inside player -

An error occurred. Please try again later

Also, I could see in the network tab that I am getting a 400 [BAD REQUEST] http response for the request

http://ift.tt/1yMHfxz

The error is

{"errors": ["The URL contained a malformed username.", "Invalid request."]}

I need help with embedding this channel using channel id on a webpage. Any help will be appreciated.
