General-purpose compute
A practical starting point for mixed workflows, evaluation, and deployments where the preferred instance family is widely available.
Browser-based production monitoring
Callaba Multiview
Arrange live inputs on a browser Multiview board and check picture, audio and stream state before the feed reaches its next job.
Visible operator workflow
Many live inputs, one operating view
Bring configured sources into one private or public board, arrange up to 16 tiles, and identify the exact stream, picture, codec, resolution, frame rate, bitrate, audio level, and connection state that needs attention.
COMPUTE PATH
Choose the Multiview compute path from the workload
Callaba Multiview can run on general-purpose compute, while selected builds and deployment regions may expose an FPGA-accelerated option. Both serve the same operator job: decode the required feeds, compose the wall, and keep signal health visible.
FPGA media acceleration
A specialised path for supported media workloads when the compatible Callaba image, accelerator instance, and region are available.
Validate the real wall before choosing capacity
- Build the production layout with the actual codecs, resolutions, and frame rates; input count alone is not a capacity test.
- Run all expected sources together and inspect utilisation, decoded video, and output stability.
- Leave headroom for reconnects, layout changes, and event-day variation.
- Confirm the current Callaba build, cloud region, and instance availability before committing the production design.
AWS VT1 instances use Xilinx Alveo U30 media accelerator cards. Published AWS performance examples are platform guidance, not a guarantee for an untested Multiview layout. Review the current AWS VT1 specification and availability.
What the product does
A multiview built around real input states
Give operators one shared board for live feeds, layouts and signal checks.
Bring SRT, RTMP, NDI, and browser cameras together
Use configured SRT or RTMP streams, discovered NDI devices, and phone-camera invitations as inputs to the same board. Reuse an invitation until an operator explicitly revokes it.
Choose layouts from one tile to 16
Use single-view, picture-in-picture, 2, 4, 6, 9, 10, 12, or 16-tile layouts and update the board as the production changes.
See the signal context on every tile
Expose the label, VU meter, protocol, codec, resolution, frame rate, bitrate, status, mute state, visibility, volume, and connection events that belong to the selected stream.
Use cases
One product for distributed video operations
Use the board with live telemetry, then continue to recording, routing or playback.
Remote production
Give producers and engineers a common view of contribution feeds without shipping a dedicated monitor wall to every location.
Broadcast and streaming control rooms
Keep contribution, program, and delivery inputs together while operators inspect the state of each tile during a live workflow.
Security and site monitoring
Combine compatible camera feeds in a browser wall for live observation when the requirement is operational viewing rather than a full VMS.
Read-only stream-health assessment
See the live path before changing it
Pair Multiview with current SRT/RTMP operator telemetry to understand live state and establish a normal baseline from observed samples.
- 01
Observe the live state
Place program pictures beside current source state, bitrate, and SRT RTT where available.
- 02
Establish a working baseline
Compare live observed samples with the normal bitrate, RTT, and source-state range for this production.
- 03
Review reason-coded warnings
Turn deviations into clear operator warnings and require approval before any route change.
Technical specification
What the product supports, and what to verify
Supported behavior sits beside a practical acceptance check. The installed Callaba interface and the real source, destination, and infrastructure profile remain authoritative.

Deployment
Run Multiview in the cloud or on your Linux infrastructure
Use the same product workflow with a managed Callaba instance or a self-hosted Callaba Engine deployment.
Cloud deployment
Deploy a Callaba instance and build the board through the web interface without preparing your own server.
Deploy Callaba on AWSSelf-hosted deployment
Install Callaba Engine on Linux when infrastructure placement, networking, and data control must stay with your team.
Install on LinuxAPI is the second layer

After the operator flow is clear, use the Multiview API to create, update, start, stop, inspect, and join boards from your own control plane.
- Create or update the Multiview board and its layout
- Start the board and inspect its current state
- Join through the reviewed private or public access path
Multiview questions
What is Callaba Multiview?
Callaba Multiview is a browser-based live video board that combines configured inputs into an operator-selected layout and exposes the state of each tile.
Which inputs can I place in a Multiview board?
The released workflow supports selected streams from configured SRT and RTMP servers, discovered NDI devices, and phone-camera invitations. An invitation can be reused until it is explicitly revoked.
How many tiles and layouts are available?
The product includes one-tile, picture-in-picture, 2, 4, 6, 9, 10, 12, and 16-tile layouts. The useful layout depends on the number and role of your sources.
Can a Multiview board be shared?
A board can be configured as private or public. Treat a public board identifier as shareable access material and use a private board for restricted operations.
Can I control Multiview through the API?
Yes. The API exposes reviewed operations for creating, updating, removing, starting, stopping, inspecting, and joining Multiview boards.
What is a video wall?
A video wall is a visual arrangement of multiple video sources on one display surface or across several displays. Callaba Multiview is the operator-facing software view that decodes, composes, and monitors those live inputs; the physical screens and their controllers remain a separate display layer.
What is a video wall and how does it work?
A video wall is a view that arranges several video sources on one display surface or across multiple displays. Callaba Multiview is the browser-based operator view: add the accepted live inputs to a board, choose a layout, inspect each tile and share the board when appropriate. The physical displays, mounting, and any display-controller hardware remain a separate layer; verify the live input and tile state before relying on the view in production.
