Video Structure:

An Event object often specifies a Video object, which contains information on the streaming URLs and protocols.

Below is an example indicating a typical structure. Depending on the Event State different URL objects are populated, but the structure within each is similar.

Other infrastructure information is also included, such as rampServers, and this is defined by the selected Channel and it’s configuration.

PUT /event/forcestop/{id}

Use this method to force an event into a stopped state. This function will also force stop the encoder channel running - bypassing the concurrency lock mechanism and removing any existing locks. Should be used as a last resort in case the lock synchronisation becomes out of sync.

Warning: Potentially dangerous as no checks will be made to see if a different Event is running on the associated Channel.

Response: 200 OK

---

PUT /event/state/{id}

Update the Event state.

Send 1 (LIVE_UNPUBLISHED) or 2 (LIVE_PUBLISHED) to start the encoder.
