The above 'plugin' is a very old addon for the 'more fields' plugin, very outdated. This 'plugin' adds a custom field type 'kaltura' which allows us to browse our kaltura videos from the kaltura server and then choose and insert a selected video into a custom field.

I've been trying to 'convert' this concept to work with Jared's custom meta box plugin, but I am currently stuck.

Can someone help out in converting the above logic to work with Jared's plugin?

thanks

Can you show (with another gist) what you've tried so far?

I'd post what I have tried, but absolutely nothing has come even close to working. 90% of the time I end up 500 error etc..
I'll keep working on it, and if I get any closer at all, I'll post it here for everyone.
