" -b, --bit-rate value\n"
" Encode the video at the given bit-rate, expressed in bits/s.\n"
" Unit suffixes are supported: 'K' (x1000) and 'M' (x1000000).\n"
" Default is " STR(DEFAULT_BIT_RATE) ".\n"
"\n"
" --codec-options key[:type]=value[,...]\n"
" Set a list of comma-separated key:type=value options for the\n"
" device encoder.\n"
" The possible values for 'type' are 'int' (default), 'long',\n"
" 'float' and 'string'.\n"
" The list of possible codec options is available in the\n"
" Android documentation:\n"
" <https://d.android.com/reference/android/media/MediaFormat>\n"
"\n"
" --crop width:height:x:y\n"
" Crop the device screen on the server.\n"
" The values are expressed in the device natural orientation\n"
" (typically, portrait for a phone, landscape for a tablet).\n"
" Any --max-size value is computed on the cropped size.\n"
"\n"
" --disable-screensaver\n"
" Disable screensaver while scrcpy is running.\n"
"\n"
" --display id\n"
" Specify the display id to mirror.\n"
"\n"
" The list of possible display ids can be listed by:\n"
" adb shell dumpsys display\n"
" (search \"mDisplayId=\" in the output)\n"
"\n"
" Default is 0.\n"
"\n"
" --encoder name\n"
" Use a specific MediaCodec encoder (must be a H.264 encoder).\n"
"\n"
" --force-adb-forward\n"
" Do not attempt to use \"adb reverse\" to connect to the\n"
" the device.\n"
"\n"
" --forward-all-clicks\n"
" By default, right-click triggers BACK (or POWER on) and\n"
" middle-click triggers HOME. This option disables these\n"
" shortcuts and forward the clicks to the device instead.\n"
"\n"
" -f, --fullscreen\n"
" Start in fullscreen.\n"
"\n"
" -h, --help\n"
" Print this help.\n"
"\n"
" --legacy-paste\n"
" Inject computer clipboard text as a sequence of key events\n"
" on Ctrl+v (like MOD+Shift+v).\n"
" This is a workaround for some devices not behaving as\n"
" expected when setting the device clipboard programmatically.\n"
"\n"
" --lock-video-orientation [value]\n"
" Lock video orientation to value.\n"
" Possible values are \"unlocked\", \"initial\" (locked to the\n"
" initial orientation), 0, 1, 2 and 3.\n"
" Natural device orientation is 0, and each increment adds a\n"
" 90 degrees rotation counterclockwise.\n"
" Default is \"unlocked\".\n"

"\n"
" --max-fps value\n"
" Limit the frame rate of screen capture (officially supported\n"
" since Android 10, but may work on earlier versions).\n"
"\n"
" -m, --max-size value\n"
" Limit both the width and height of the video to value. The\n"
" other dimension is computed so that the device aspect-ratio\n"
" is preserved.\n"
" Default is 0 (unlimited).\n"
"\n"
" -n, --no-control\n"
" Disable device control (mirror the device in read-only).\n"

" Do not display device (only when screen recording is\n"
" enabled).\n"
"\n"
" --no-key-repeat\n"
" Do not forward repeated key events when a key is held down.\n"
"\n"
" --no-mipmaps\n"
" If the renderer is OpenGL 3.0+ or OpenGL ES 2.0+, then\n"
" mipmaps are automatically generated to improve downscaling\n"
" quality. This option disables the generation of mipmaps.\n"
"\n"
" -p, --port port[:port]\n"
" Set the TCP port (range) used by the client to listen.\n"
" Default is " STR(DEFAULT_LOCAL_PORT_RANGE_FIRST) ":"
STR(DEFAULT_LOCAL_PORT_RANGE_LAST) ".\n"
"\n"
" --prefer-text\n"
" Inject alpha characters and space as text events instead of\n"
" key events.\n"
" This avoids issues when combining multiple keys to enter a\n"
" special character, but breaks the expected behavior of alpha\n"
" keys in games (typically WASD).\n"
"\n"
" --push-target path\n"
" Set the target directory for pushing files to the device by\n"
" drag & drop. It is passed as-is to \"adb push\".\n"
" Default is \"/sdcard/\".\n"
"\n"
" -r, --record file.mp4\n"
" Record screen to file.\n"

" set, or by the file extension (.mp4 or .mkv).\n"
"\n"
" --record-format format\n"
" Force recording format (either mp4 or mkv).\n"
"\n"
" --render-driver name\n"
" Request SDL to use the given render driver (this is just a\n"
" hint).\n"
" Supported names are currently \"direct3d\", \"opengl\",\n"
" \"opengles2\", \"opengles\", \"metal\" and \"software\".\n"
" <https://wiki.libsdl.org/SDL_HINT_RENDER_DRIVER>\n"
"\n"
" --rotation value\n"

"\n"
" -s, --serial serial\n"
" The device serial number. Mandatory only if several devices\n"
" are connected to adb.\n"
"\n"
" --shortcut-mod key[+...]][,...]\n"
" Specify the modifiers to use for scrcpy shortcuts.\n"
" Possible keys are \"lctrl\", \"rctrl\", \"lalt\", \"ralt\",\n"
" \"lsuper\" and \"rsuper\".\n"
"\n"
" A shortcut can consist in several keys, separated by '+'.\n"
" Several shortcuts can be specified, separated by ','.\n"
"\n"
" For example, to use either LCtrl+LAlt or LSuper for scrcpy\n"
" shortcuts, pass \"lctrl+lalt,lsuper\".\n"

"\n"
" -S, --turn-screen-off\n"
" Turn the device screen off immediately.\n"
