This project is a wrapper for media streaming servers that integrates to streaming servers with the Kaltura Server. The Kaltura Media Server is an application built to run over the Wowza Streaming Engine By default, the Kaltura Streaming application is called kLive.
The Kaltura media server can use API client in one of two configurable ways:
- Opposite built-in partner (-5), which impersonates the handled partner for all API calls.
- As an eCDN installation- in this case the streaming server (e.g. Wowza) is installed on the client's machine while the partner continues working opposite the SaaS installation (as opposed to on-prem installations). The streaming server thus installed works only opposite the partnerId it belongs to and does not use impersonation.
The KS is regenerated periodically according to the KS expiry time.
Example URL to kLive application: rtmp://domain/kLive/?p=102&e=0_rkij47dr&i=0&t=dj94kfit
The broadcast URL consists of the following arguments:
- p – partner id.
- e – entry id.
- i – index (0 for primary and 1 for backup).
- t – token.
Stream name example: 0_rkij47dr_1
The stream name consists of entry id, underscore and stream index (between 1 to 3).
The stream index could be used for multiple bitrate streams ingestion, if only one bitrate is streamed the index should be 1.
- Connection – liveStream.authenticate action is called to validate the entry id with the supplied token. The action should return a KalturaLiveStreamEntry object, or an exception in case the authentication failed. The returned entry object could be used later to determine if DVR and recording are enabled for this entry.
- Transcoding - wowza_liveStreamConversionProfile.serve is called for each published entry. This action returns an XML formatted according to the Wowza required structure, indicating the transcoding that the stream should undergo.
