# fhdcapture - capturing picture from FullHD Capture webcam device
## Purpose
# This script launches mplayer that is showing image from usb webcam.
# I am using it with ezcap device and SimpleScreenRecorder at second laptop.
# This way I am able to shot videos otherwise impossible to capture, for example,
# actions in bios setup or in bootloader.
#
# It is needed because vlc has ugly mess with colors while showing picture from ezcap.
# If you know how to fix this, feel free to contact me or open a new issue.

echo "\$EZCAP_ENUM = $EZCAP_ENUM"
killall mplayer # ensure that we finished previous fhdcapture instance
mplayer -fs tv:// -tv driver=v4l2:device=/dev/video$EZCAP_ENUM:width=1920:height=1080:fps=30:outfmt=yuy2 > /dev/null 2>/dev/null &
sleep 1 # Do not remove. It's needed for wmctrl command to work.
wmctrl -F -r MPlayer -b add,below
wmctrl -F -r MPlayer -N "FHD Capture" # rename window title for convenience

## Usage
# $ fhdcapture
# Mplayer window will be automatically opened in fullscreen mode and go behind all other windows.
# Record it with simplescreenrecorder or obs.
# To exit mplayer fullscreen mode and show title bar, press win + f11 (my own shortcut) or press Alt + F3 to show window actions menu.
# I am launching fhdcapture in yakuake window. To stop Mplayer I close it on taskbar or press Escape after clicking in Mplayer.
