primary encoder, I suggest having it as a backup encoder.
Case 1: Single-Rig Live VR Streaming
With Vahana VR or Teradek Sphere
Figure 6 maps out a single-camera VR workflow I assembled through trial and error to use
in relatively simple VR productions.
At the heart of this setup is a VR camera rig
with HDMI/HD-SDI outputs and a workstation
PC for live stitching and encoding.
If you’re planning on building your VR work-
flow around Vahana VR, here are a few things
• For Vahana VR, software stitching is
sufficient, but for better stitching results,
consider importing a PTGui template.
• Vahana VR can be buggy at times, so I highly
recommend using a separate encoder.
• As of August 2017, Vahana VR is the only
software available that offers live-view with
Case 2: Z Cam S1-Based Complete IP Workflow
The setup diagrammed in Case 2 (see Figure
7 on page 98) shows a complete IP workflow
achieved with a Z Cam S1. To assemble this
kit, you need only one Ethernet cable between
the Z Cam S1 and a WonderLive installed ma-
chine. The Z Cam controller, WonderStitch, and
WonderLive used in the Case 1B setup, are sold
as bundled software. The caveat is that one
unique license is required per camera.
As in Case 1, software stitching is sufficient
for baseline use, but for better stitching results,
import a PTGui template.
For 360° livestreaming to the general public,
I recommend encoding directly to platforms
such as Facebook or You Tube. You can also
stream to other CDNs or services such as Bitmovin, Wowza, or Visbit when you need more
robust or customized solutions. Overall, using
Facebook or You Tube is great for standard 4K,
since they are both easy to configure and provide comprehensive dashboards to work with.
You Tube has continuously refined its live
platform and is very straightforward in its approach to panoramic live streaming. In our
projects, it has proven the most consistent and
stable platform while at the same time delivering good, high-resolution 4K streams.
You Tube supports VR streaming at up to
4K 60 fps, but depending on your bandwidth,
I suggest using more conservative specs, such
as 2560x1440 at 30 fps, uploaded at 6–10Mbps;
