Where to start OpenGL?

Sorry for a post like this, but I couldn’t find a good tutorial series. I like to learn things from tutorial videos, can you suggest me any video series on YouTube or some place for OpenGL?

I am using OpenGL in Android, but C++ videos are fine too.

Thank you.

Here are some great JOGL tutorials.
