Hi @OCX,
Using this method, the system will fetch the remote file, ingest it to the system as the source for the entry and then go on to convert it to the various flavours just as it would when uploading a file from your desktop.
That said, the system is also capable of getting a URL to a remote m3u8 and serve that stream.
For that, create a Kaltura Live Entry by going to KMC->Upload->Live Stream Entry.
For Live Stream Type, select “Manual Live Stream URLs”, provide a meaningful name for the entry, for example “My Live Test”, and input “/url/to/m3u8” in the “HLS stream URL” text box.
