How To Use displaymanager.virtual_display_flag_auto_mirror

int VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR

Virtual display flag: Allows content to be mirrored on private displays when no content is being shown.

This flag is mutually exclusive with VIRTUAL_DISPLAY_FLAG_OWN_CONTENT_ONLY. If both flags are specified then the own-content only behavior will be applied.

The behavior of this flag is implied whenever VIRTUAL_DISPLAY_FLAG_PUBLIC is set and VIRTUAL_DISPLAY_FLAG_OWN_CONTENT_ONLY has not been set. This flag is only required to override the default behavior when creating a private display.

Creating an auto-mirroing virtual display requires the CAPTURE_VIDEO_OUTPUTorCAPTURE_SECURE_VIDEO_OUTPUT permission. These permissions are reserved for use by system components and are not available to third-party applications. Alternatively, an appropriate MediaProjection may be used to create an auto-mirroring virtual display.
