I found a useful nginx module that can split on demand video files in snippets.
It's very useful for building an video on demand cdn.
I've added it to the ebuild and made a pull request.
I'll keep this bug open but bug the PR was rejected due to our nginx 3rd party module policy.
This module supports to build as a dynamic module.
Do you have a work flow to build an ebuild for only the module
or how do you plan to handle dynamic module?
Well, that's the topic of bug 573710. Basically, we need to find a solution (create an eclass or something), to allow/support module ebuilds.
I submitted a PR quite some time ago but I just updated it.
