The “Record from Webcam” KMC option relies on a Flash widget which will soon be discontinued as we’re in the process of moving away from Flash entirely.
The “Live Stream Entry” option will trigger the creation of a “live stream” Kaltura entry, allowing you to broadcast a video to Kaltura over RTMP.
You didn’t specify whether you are using CE or our SaaS platform.
For CE, live streaming is achieved using Kaltura Nginx and the RTMP module, you can read about that here:
On our SaaS ENV, a different mechanism is used, involving, among other components, the Wowza streaming server.
You can opt to create a VOD entry from your live stream and DVR is also supported.
There are many tools that support streaming over RTMP, I mentioned two of them in my last reply.
From your last reply however, I understand that your intent is to ingest a pre-recorded video file, not a live stream so neither of these options are relevant to that.
