Compared to wifi p2p, it allows stabler connection and lower latency. The spec of Miracast over Infrastructure (MICE) is available here.

all.shįor Windows 10 sources, Miracast over Infrastructure (MICE) is a feature that allows transmission of screen data over Ethernet or secure wifi networks. Start on bootĪppend this line to -l -working-directory=/home/pi/lazycast -e. HDCP(content protection): Neither the key nor the hardware is available on Pi and therefore is not supported. If it is pressed again the window will be in-focus. The left Windows key is not captured and when it is pressed, it makes the current window to be out-of-focus and thus disables the backchannel controls. Interference from other devices may cause disconnections.ĭevices may not fully support backchannel control and some keystrokes/clicks will behave differently in this case. The in-house players employ several mechanisms to conceal transmission error, but it may still be noticeable in challenging wireless environments. (In VLC, latency can be reduced from 1200 to 300ms by lowering the network cache value.)ĭue to the overcrowded nature of the wifi spectrum and the use of unreliable rtp transmission, you may experience some video glitching/audio stuttering. Latency: Limited by the implementation of the rtp player used. Currently a workaround (that constantly monitors the liveliness of player2) is implemented. Player2 seems to have a double-free bug which causes it to crash when playing some videos. Try clearing the 'lazycast' information on the source device before re-pairing if you run into pairing problems. Any insights or suggestions on this issue are appreciated, and could make this important feature work again.) Therefore, re-pairing may be needed after every Raspberry Pi reboot.

However, recent Raspbians randomize the MAC address of the p2p-dev-wlan0 interface upon reboot, while old Raspbians ( example) do not. (Using the latest Raspbian is still recommended from the security perspective. However, this feature does not seem to work properly all the time with recent Raspbian images. Lazycast tries to remember the pairing credentials so that entering the PIN is only needed once for each device. (See here for details of installing gstreamer.) Known issues VLC, omxplayer or gstreamer can be used instead on other platforms. Two in-house players are written for Raspberry Pi 3. On the other hand, since they are under the same subnet, precautions should be taken to prevent unauthorized access to Pi by anyone who knows the PIN number. To change the default PIN number, replace the string 31415926 in all.sh to another 8-digit number.Īfter Pi connects to the source, it has an IP address of 192.168.173.1 and this connection can be reused for other purposes like SSH. In this case, reduce the FPS to 1920x1080p50. The GPU on Pi may struggle to handle 1920x1080p60, which results in high latency.
The maximum resolutions supported are 1920x1080px1200p30. Modify parameters in the "settings" section in d2.py to change the sound output port (hdmi/3.5mm) and preferred player. Therefore, you may want to change the resolution (on the source) to match the actual resolution of the display connecting to Pi. lazycast advertises all possible resolutions regardless of the current rendering resolution. You can utilize the backchannel feature to remotely control the source device in order to close lazycast. These user controls are often near the pairing controls on the source device. It is recommended to initiate the termination of the receiver on the source side. If backchannel control is supported by the source, keyboard and mouse input on Pi are redirected to the source as remote controls. Then, search for this name on the source device you want to cast. The name of the display will appear after this message. Wait until the "The display is ready" message.
