Been searching for the API to embed a Youtube channel\'s user_uploads for channels which have the new channel_id (starting with UC) instead of a user n
Never seen such a username. Do you have a link to a user (youtube website) with such a username ?
Update.
It looks like it is a part of the new V3 api from youtube and I filed a bug report at the youtube dev forum since it wont't work withe the user_uploads iframe
http://code.google.com/p/gdata-issues/issues/detail?id=6463
For example this channel
https://www.youtube.com/channel/UCpAOGs57EWRvOPXQhnYHpow
then ID is UCpAOGs57EWRvOPXQhnYHpow
Now try to load this
http://www.youtube.com/embed/?listType=user_uploads&list=UCpAOGs57EWRvOPXQhnYHpow
This isn't working, Only with real usernames
