meta-openhd
===========

This layer provides support for building [OpenHD](https://github.com/OpenHD/OpenHD), an open-source digital video transmission system, with the Yocto Project.

Dependencies
------------
* Compatible with the Yocto Project "scarthgap" release
* Depends on the core `poky` layer

## Build Dependencies

To compile `openhd-webui`, the host machine must have the .NET 9 SDK installed.

### Ubuntu 22.04:

To make the WebUi work you need to add dotnet (9) to your host 
```bash
sudo apt update
sudo apt install -y wget apt-transport-https software-properties-common
wget https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt update
sudo apt install -y dotnet-sdk-9.0
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y --allow-downgrades --allow-remove-essential --allow-change-held-packages nodejs npm -o Dpkg::Options::="--force-overwrite"
```

Adding the layer to your build
------------------------------
Clone this repository into your Yocto build tree and register the layer:

    bitbake-layers add-layer meta-openhd

Building OpenHD
---------------
Once the layer is added, the OpenHD application can be built with:

    bitbake openhd

The `openhd_git.bb` recipe tracks the latest commits from the OpenHD GitHub repository. The layer sets `BB_SRCREV_POLICY = "latest"` and the recipe uses `SRCREV = "${AUTOREV}"`, ensuring the build system checks for new upstream revisions each time the recipe is executed.
