Get currently loaded app

Post by patrickrho » Fri Apr 24, 2015 5:01 am

We want to solve this problem where when multiple people are looking at the same screen and one goes back or closes the app then the app is unloaded for everybody.

Would it be possible for us to actually load multiple apps at the same time?

Or can we get currently loaded app to handle this situation? For example, we want to prevent other users to load other apps if an app is already loaded.
Thanks!

First off, the bazaar infrastructure is not designed for support of multiple concurrent sessions. It might be possible to add support for one master plus multiple viewers with limited control capabilities - eg no loading or unloading of apps and no changing of hardware parameters like trigger settings.

That is also possible, and not very difficult to achieve. The source files
Bazaar/nginx/ngx_ext_modules/ngx_http_rp_module/src/rp_bazaar_cmd.c and
Bazaar/nginx/ngx_ext_modules/ngx_http_rp_module/src/rp_bazaar_app.c
handle loading and unloading of apps. You could probably store the session of the app-starter and prohibit other sessions from using the load / unload functions.
