Using Live Stream and Live Capture Concurrently
A Lightspeed Live Server can host Lightspeed Live Capture or Lightspeed Live Stream
independently, or host both applications simultaneously, sharing SDI and network-
based sources.
Note: Release notes and Support Services are the best sources of compatibility
information regarding the use of Live Stream and Live Capture on the same server.
Although both applications can operate stand-alone, the greatest benefits are realized
when Lightspeed Live Stream is installed on a Lightspeed Live Server with Live Capture
coupled to Telestream’s Vantage platform for complete workflow orchestration. In this
configuration, you can concurrently stream, capture, and process live content for
consumption on a wide variety of platforms.
Lightspeed Live Capture, in addition to operating as a standalone capture system, can
extend live encoding capability by providing live capture in a number of high-quality
mezzanine formats in the Vantage Media Processing Platform. Through this integration,
users can simultaneously make use of both the real-time streaming capability and the
full range of video manipulation that Vantage offers.
Shared Resource Allocation
Since Live Capture and Live Stream use shared operating resources, care is needed to
avoid over subscription of CPU, GPU, memory, and other resources. Source content
coming through the Lightspeed Live server inputs can be used by both Live Capture
and Live Stream. See
Lightspeed Live Capture Resource Calculator in the Lightspeed Live
Capture User Guide (this guide) for details on calculating Live Capture resource usage.
Certain Stream Sources are Not Supported for Capture Use
Lightspeed Live systems do not limit how Capture and Stream can be configured
together, which allows for nearly unlimited combinations of resources. Live Stream
enables you to create File Loop, RTMP, Slate, and Transport Streams Sources. When
Stream and Capture are used on a server concurrently, these Sources also display in the
Sources list of the Capture action, in addition to the SDI sources that Capture and
Stream can both use.
File Loop and Slate sources are available as sources but are not supported for Capture
workflows, and are reserved for use in the Stream Web app. For information on where
the sources are selected, see the Capture
Program Input Panel in the Creating Capture
and Tape Action Workflows chapter.
