base on Connect external monitors to your system via Wifi-Display specification also known as Miracast # MiracleCast - Wifi-Display/Miracast Implementation [](https://gitter.im/albfan/miraclecast?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [](https://albfan.semaphoreci.com/projects/miraclecast) [](https://coveralls.io/github/albfan/miraclecast?branch=master) The MiracleCast project provides software to connect external monitors to your system via Wi-Fi. It is compatible to the Wifi-Display specification also known as Miracast. MiracleCast implements the Display-Source as well as Display-Sink side. The Display-Source side allows you to connect external displays to your system and stream local content to the device. A lot of effort is put into making this as easy as connecting external displays via HDMI. *Note: This is not implemented yet. Please see [#4](../../issues/4).* On the other hand, the Display-Sink side allows you to create wifi-capable external displays yourself. You can use it on your embedded devices or even on full desktops to allow other systems to use your device as external display. ## Requirements The MiracleCast projects requires the following software to be installed: - **systemd**: A system management daemon. It is used for device-management (udev), dbus management (sd-bus) and service management. Systemd >= 221 will work out of the box. For earlier versions systemd must be compiled with --enable-kdbus, even though kdbus isn't used, but only the independent, experimental sd-libraries. *required*: >=systemd-213 - **glib**: A utility library. Used by the current DHCP implementation. Will be removed once sd-dns gains DHCP-server capabilities. *required*: ~=glib2-2.38 (might work with older releases, untested..) - **gstreamer**: MiracleCast rely on gstreamer to show cast its output. You can test if all needed is installed launching [res/test-viewer.sh](https://github.com/albfan/miraclecast/blob/master/res/test-viewer.sh) - **wpa_supplicant**: MiracleCast spawns wpa_supplicant with a custom config. - **P2P Wi-Fi device** Although widespread these days, there are some devices not compatible with [Wi-Fi Direct](http://en.wikipedia.org/wiki/Wi-Fi_Direct) (prior know as Wi-Fi P2P). Test yours with [res/test-hardware-capabilities.sh](https://github.com/albfan/miraclecast/blob/master/res/test-hardware-capabilities.sh) - **check**: Test-suite for C programs. Used for optional tests of the MiracleCast code base. *optional*: ~=check-0.9.11 (might work with older releases, untested..) - copy the dbus policy **res/org.freedesktop.miracle.conf** to `/etc/dbus-1/system.d/` ## Build and install To compile MiracleCast, you can choose from: - [autotools](http://en.wikipedia.org/wiki/GNU_build_system) - [cmake](http://en.wikipedia.org/wiki/CMake) - [meson](http://mesonbuild.com/) See more info on wiki [Building](https://github.com/albfan/miraclecast/wiki/Building) ## Automatic interface selection with udev If you want to select the interface to start miraclecast with, add a udev rule with the script [res/write-udev-rule.sh](https://github.com/albfan/miraclecast/blob/master/res/write-udev-rule.sh) and configure miraclecast with $ ../configure --enable-rely-udev You can also choose the interface with `--interface` option for miracle-wifid. ## Linux Flavours and general compilation instructions ### Ubuntu Check your systemd version with: $ systemctl --version If you are on 221 or above your systemd has kdbus enabled. If you are below 221, an alternative repo was created to install systemd with dbus https://github.com/albfan/systemd-ubuntu-with-dbus See there was interface changes on systemd 219, if you are below that version, use branch [systemd-219](https://github.com/albfan/miraclecast/tree/systemd-219) to compile miraclecast > See specific instructions on that repo ### Arch linux Use existing [AUR package](https://aur.archlinux.org/packages/miraclecast-git/). Remember to enable kdbus to systemd-git dependency if you are below 221 systemd. $ export _systemd_git_kdbus=--enable-kdbus You can achieve installation using [yaourt](https://wiki.archlinux.org/index.php/Yaourt) ### Other flavours If you feel confidence enough (since systemd is the entrypoint for an OS) extract instructions from arch linux AUR PKGBUILD: - [systemd-kdbus](https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=systemd-kdbus) - [miraclecast](https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=miraclecast) ## Documentation ### Steps to use it as sink 1. shutdown wpa_supplicant and NetworkManager $ systemctl stop NetworkManager.service $ systemctl stop wpa_supplicant.service 2. launch wifi daemon $ sudo miracle-wifid & 3. launch sink control (your network card will be detected. here 3) $ sudo miracle-sinkctl [ADD] Link: 3 4. run WiFi Display on link: > run 3 5. Pair your machine with other miracast device (mirroring) 6. See your screen device on this machine ### Steps to use it as peer 1. Repeat steps 1 and 2 from "use as sink" 2. launch wifi control $ sudo miracle-wifictl 3. Enable visibility for other devices 4. Locate them using scanning > p2p-scan 5. Apart from list, or show info with peer <mac> there's nothing useful here by now. For a Q&D see [Using as peer](https://github.com/albfan/miraclecast/issues/4) ## UIBC > The User Input Back Channel (UIBC) is an optional WFD feature that when implemented facilitates communication of user inputs to a User Interface, present at the WFD Sink, to the WFD Source. To use it just add `--uibc` on `miracle-sinkctl` startup. Single mouse events and key events are implemented. ## Autocompletion Source [res/miraclecast-completion](https://github.com/albfan/miraclecast/blob/master/res/miraclecast-completion) for autocompletion ## License This software is licensed under the terms of the GNU-LGPL license.
