We have servers with wowza 4 and a few still which we haven't upgrade and running on wowza 3. The issue is that on wowza 3 it is easy to create a live app change the stream type to default, enter a path for the saving of the videos and that's it, the app will record the live broadcast and the same app will then stream the videos just like vod. this is useful for video comments scripts like the wordpress plugin contus ( wordpress.org/plugins/contus-video-comments/ ). Now with the wowza 4 the engine manager doesn't setup this kind app,at least we haven't had any success. is there a way to do it?
