scrpy notes for Android

# Note (script compatability): this is given as a shell script intended for use on macOS, but it works perfectly fine on Windows in Powershell too!

# Note (specifying device): I usually specify serial for ADB/scrcpy, because I typically run with
# both USB and wireless debugging enabled. If you only have one available
# device for ADB debugging, you can skip that!]

# Note: (web conferencing): Last I recall, Zoom/Meet cap out at 30FPS. So if you're intending to share stuff there, going beyond 30 FPS won't really provide value.

# Set device identifer

# Unix (sh/bash/zsh etc)
# serialNumber="your_device_serial_here"
# Windowz
# $serialNumber = "your_device_serial_here"

# Info gathering

# Get available cameras
scrcpy -s "$serialNumber" --list-cameras

# Get available camera "sizes" / formats
scrcpy -s "$serialNumber" --list-camera-sizes

# Get device displays
scrcpy -s "$serialNumber" --list-displays

# Get available audio/video encoders
scrcpy -s "$serialNumber" --list-encoders

# Get available apps
scrcpy -s "$serialNumber" --list-apps

# General mirroring

# Generic mirroring. Sets the max FPS to 165, which is my desktop monitor's
# refresh rate. Also slightly ups video bitrate from default to 10M, and
# significantly ups audio bitrate from default to 365k.

# Camera stuff

# Camera mirroring
# I disable the audio because I'm not interested in the phone microphone
# audio ususally, I have better mics. And if you are using speakers for output
# watch out for audio feedback!

# Camera mirroring only (30 FPS -> more FPS, lighting is harder/darker)

# Camera mirroring, landscape

# other flags I find personall useful:
# -t / --show-touches: shows PHYSICAL touches on screen
# --window-borderless: borderless window (no title bar, no close/minimize buttons)
# --no-audio-playback: Disable audio playback on the computer
# --no-audio: Disable audio forwarding
# -n / --no-control: Disable device control (mirror the device in read-only).
