The rule placed every video4linux and media node in video-capture, but most are not capture devices: on an rk3588 board five of the six V4L2 nodes are the RGA blitter and the Hantro and rkvdec stateless codecs, and only the HDMI receiver captures anything. A media player then had to join video-capture to reach a decoder, which also granted it every camera on the box. Put the DRM and media nodes in video, and add v4l-id, which runs VIDIOC_QUERYCAP and prefers device_caps over capabilities so that what it describes is the node. Given a device alone it prints one boolean per V4L2_CAP_ flag as JSON. Given a rule string as well, a list of CAP[,CAP...]:GROUP separated by semicolons in which * matches any node, it puts the node into the group of the first rule which matches it. The rule string is parsed in full before the device is opened, so a capability name the kernel does not define is reported whichever rule it appears in, and no node is touched. A V4L2 node is created with no group and v4l-id assigns one, since exec is queued by procd and may not run at all; holding the node at root until the driver answers keeps a camera out of video.

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.8+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.
