Supported Boards

This firmware is supported on the following to boards;

• Digilent Atlys - BOARD=atlys - http://digilentinc.com/atlys/

  The original board used for HDMI2USB prototyping.

  

• Numato Opsis - BOARD=opsis - https://crowdsupply.com/numato-lab/opsis

  The first production board made in conjunction with TimVideos.us project.

  

For a comparison between the supported boards, see the HDMI2USB Hardware page.

Development Boards

• Pipistrello - http://pipistrello.saanlima.com/

  BOARD=pipistrello

  A small FPGA board with only one HDMI output port. Due to the lack of video inputs, this board is only useful for developers.

• miniSpartan6+ - https://www.scarabhardware.com/minispartan6/ - In progress

  BOARD=miniSpartan

  A small FPGA board with HDMI input and HDMI output. Due to the low speed ram and USB interface, this board is only useful for developers who want to work on the HDMI subsystem and need a small board that fits in their pocket.

Getting started

For using a HDMI2USB board, prebuilt versions of the firmware are available in the HDMI2USB-firmware-prebuilt repository.

For helping with the development, instructions for setting up the build environment are found in the scripts/README.md file.

Documentation

User documentation is found on the HDMI2USB website.

High level developer documentation for the firmware can be found in the doc directory. More documentation is found in the source code.

Current Status

HDMI2USB

The hdmi2usb targets are for doing capturing and streaming using the FX2 USB interface.

Atlys

atlys_hdmi2usb

• VideomixerSoC validated: MiniSoC + 2 x HDMI in + 2 x HDMI out
• HDMI2USBSoC validated: VideomixerSoC + JPEG encoder + USB streaming

Opsis

opsis_hdmi2usb

• VideomixerSoC validated: MiniSoC + 2 x HDMI in + 2 x HDMI out
• HDMI2USBSoC validated: VideomixerSoC + JPEG encoder + USB streaming

HDMI2Eth

The hdmi2eth targets are for doing capturing and control using the Ethernet found on many boards.

Atlys

atlys_hdmi2eth

• EtherboneSoC validated: BaseSoC + 10/100Mbps HW Ethernet UDP/IP stack and Etherbone

• VideomixerSoC validated: EtherboneSoC + HDMI in + HDMI out

• HDMI2ETHSoC validated: VideomixerSoC + JPEG encoder + UDP streaming

Base

The base targets are used during initial bring up and verification of basic features. Getting MiniSoc running on new hardware is the first step towards supporting it. All the other, more functional, targets are built on top of this target.

Atlys

atlys_base

• BaseSoC validated: CPU + DDR2 + UART
• MiniSoC validated: BaseSoC + 10/100Mbps Ethernet MAC handled by the CPU

Opsis

opsis_base

• BaseSoC validated: CPU + DDR3 + UART
• MiniSoC validated: BaseSoC + 1Gbps Ethernet MAC handled by the CPU

Pipistrello

pipistrello_base

• BaseSoC: CPU + LPDDR + UART
• VideomixerSoC: BaseSoC + HDMI out

miniSpartan6+

• BaseSoC: CPU + UART

The HDMI2USB Project

The HDMI2USB project develops affordable hardware options to record and stream HD videos (from HDMI & DisplayPort sources) for conferences, meetings and user groups.

We are currently developing our own hardware (the Numato Opsis, and also provide firmware for various prototyping boards.

HDMI2USB started in 2013, and is an active ongoing project in its third iteration of hardware prototyping. Today you can download early working firmware and have real capture happen, but we actively wish to improve and are seeking assistance:

• For video recording individuals+teams: Be an early adopter; get a board, start using it, report back to us with feedback

• For software/FPGA developers: Get involved in contributing code both to the capture software + FPGA stack

Our aim is this becomes the defacto, incredibly affordable and easy to use video recording hardware for conferences, meetings and user groups worldwide.
