pixelpwnr-cast

A quick pixelflut (video) client in Rust for use at 37C3, that streams your screen to pixelflut panels.

For a high performance pixelflut client and server implementations, see:

• pixelpwnr: client to flut (animated) images
• pixelpwnr-server: server

Features

• Stream your desktop in real-time
• Many concurrent drawing pipes, fast multithreading
• Control over render sizes and offset
• Automatic image sizing and formatting
• Blazingly fast binary protocol (PB with --binary)
• Linux (X11), Windows and macOS

Usage

Cast your desktop:

# Flut your screen
# - To host 127.0.0.1 on port 8080
# - With 4 painting threads
# - With the size of the screen (default)
pixelpwnr-cast 127.0.0.1:8080 -c 4

Cast to a small frame:

# Flut your screen to a small frame
# - To host 127.0.0.1 on port 8080
# - With 4 painting threads
# - With a size of (400, 300)
# - With an offset of (100, 100)
pixelpwnr-cast 127.0.0.1:8080 -c 4 -w 400 -h 300 -x 100 -y 100

Use the --help flag, or see the help section for all available options.
