Romain Vimont 145b823b1d Add --no-vd-system-decorations 
Add an option to disable the following flag for virtual displays:

    DisplayManager.VIRTUAL_DISPLAY_FLAG_SHOULD_SHOW_SYSTEM_DECORATIONS

Some devices render a broken UI when this flag is enabled.

Virtual display

New display

To mirror a new virtual display instead of the device screen:

scrcpy --new-display=1920x1080
scrcpy --new-display=1920x1080/420  # force 420 dpi
scrcpy --new-display         # use the main display size and density
scrcpy --new-display -m1920  # ... scaled to fit a max size of 1920
scrcpy --new-display=/240    # use the main display size and 240 dpi

Start app

On some devices, a launcher is available in the virtual display.

When no launcher is available, the virtual display is empty. In that case, you must start an Android app.

For example:

scrcpy --new-display=1920x1080 --start-app=org.videolan.vlc

System decorations

By default, virtual display system decorations are enabled. But some devices might display a broken UI;

Use --no-vd-system-decorations to disable it.

Note that if no app is started, no content will be rendered, so no video frame will be produced at all.
