Posting to make it clearer on what’s possible and what’s not, at this time
1. Using the plugin alone, only admin can broadcast; you may use the static rtmp feature and distribute RTMP URLs to broadcasters, this way they can broadcast without actually interacting with the backend
2. If using the theme, it is possible to enable broadcasting for regular users, see this and this
3. Broadcasting in PPV as a regular user is not yet supported; it has been requested repeatedly and we are considering it for the next release; you can upvote it right here
4. Setting up multi-vendor (#3 assumes all funds go to admin) is a more complex undertaking and honestly not a very popular one; we will still consider it if asked for repeatedly
We are happy to announce that by popular demand, our next update includes a feature allowing broadcasting as a regular user (i.e not admin) and WooCommerce multivendor. Please watch the space in this thread and be the first to implement it.
Thanks for your question. I can confirm that WpStream works with any plugin and theme on WordPress. Moreover, we often recommend that our customers use WooCommerce for Payments with selling their videos so I am sure any WooCommerce multivendor plugin will work. Of course, please do not hesitate to let us know if anything goes wrong.
