picast is a simple wifi display receiver written by Python on Raspberry Pi.
Run apt install command on Rasbpian / Raspberry Pi Zero W/WH, or Raspberry Pi 3
$ sudo apt install net-tools python3 udhcpd python-gst-1.0 libgtk-3-dev python3-gi gir1.2-gtk-3.0 $ sudo apt install gir1.2-gstreamer-1.0 gir1.2-gst-plugins-base-1.0 gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly $ sudo apt install gstreamer1.0-omx-bellagio-config $ sudo apt install --no-install-recommends lxde $ pip install picast
Note: udhcpd is a DHCP server for Ubuntu and Debian.
Increase GPU memory for decoding fullHD video stream. add gpu_mem=128 to /boot/config.txt
$ picast
Then, search for the wireless display named "picast" on the source device you want to cast. Use "12345678" for a WPS PIN number. It is recommended to initiate the termination of the receiver on the source side.
After Pi connects to the source, it has an IP address of 192.168.173.1
Edit /home/pi/.config/lxsessions/LXDE/autostart and add line @picast

- Resolution: picast advertised some fixed resolutions rather than connected display resolution.
- Latency: Limited by the implementation of the rtp player, omxplayer, used.
- WiFi: The on-board WiFi chip on Pi 3/Zero W only supports 2.4GHz. Due to the overcrowded nature of the 2.4GHz spectrum and the use of unreliable rtp transmission, you may experience some video glitching/audio stuttering.
- HDCP(content protection): Neither the key nor the hardware is available on Pi and therefore is not supported.
