 Here are the instructions to build _scrcpy_ (client and server).
 
+You may want to build only the client: the server binary, which will be pushed
+to the Android device, does not depend on your system and architecture. In that
+case, use the [prebuilt server] (so you will not need Java or the Android SDK).
 
-## Simple
-
-If you just want to install the latest release from `master`, follow this
-simplified process.
-
-First, you need to install the required packages:
-
-```bash
-# for Debian/Ubuntu
-sudo apt install ffmpeg libsdl2-2.0-0 adb wget \
-                 gcc git pkg-config meson ninja-build libsdl2-dev \
-                 libavcodec-dev libavdevice-dev libavformat-dev libavutil-dev \
-                 libusb-1.0-0 libusb-1.0-0-dev
-```
-
-Then clone the repo and execute the installation script
-([source](install_release.sh)):
-
-```bash
-git clone https://github.com/Genymobile/scrcpy
-cd scrcpy
-./install_release.sh
-```
-
-When a new release is out, update the repo and reinstall:
-
-```bash
-git pull
-./install_release.sh
-```
-
-To uninstall:
-
-```bash
-sudo ninja -Cbuild-auto uninstall
-```
-
-
-## Branches
-
-### `master`
-
-The `master` branch concerns the latest release, and is the home page of the
-project on GitHub.
-
-
-### `dev`
-
-`dev` is the current development branch. Every commit present in `dev` will be
-in the next release.
-
-If you want to contribute code, please base your commits on the latest `dev`
-branch.

-
 Here are the common reported problems and their status.
 
-If you encounter any error, the first step is to upgrade to the latest version.
 
+### On Windows, my device is not detected
 
-## `adb` issues
+The most common is your device not being detected by `adb`, or is unauthorized.
+Check everything is ok by calling:
 
-`scrcpy` execute `adb` commands to initialize the connection with the device. If
-`adb` fails, then scrcpy will not work.
+    adb devices
 
-This is typically not a bug in _scrcpy_, but a problem in your environment.
+Windows may need some [drivers] to detect your device.
 
-
-### `adb` not found
-
-You need `adb` accessible from your `PATH`.
-
-On Windows, the current directory is in your `PATH`, and `adb.exe` is included
-in the release, so it should work out-of-the-box.
-
-
-### Device not detected
-
->     ERROR: Could not find any ADB device
-
-Check that you correctly enabled [adb debugging][enable-adb].
-
-Your device must be detected by `adb`:
-
-```
-adb devices

-
-If your device is not detected, you may need some [drivers] (on Windows). There is a separate [USB driver for Google devices][google-usb-driver].

-
-If several devices are connected, you will encounter this error:
-
->     ERROR: Multiple (2) ADB devices:

->     ERROR: Select a device via -s (--serial), -d (--select-usb) or -e (--select-tcpip)
-
-In that case, you can either provide the identifier of the device you want to
-mirror:
-
-```bash
-scrcpy -s 0123456789abcdef
-```
-
-Or request the single USB (or TCP/IP) device:
-
-```bash

->     ERROR: "adb reverse" returned with value 1
->     WARN: 'adb reverse' failed, fallback to 'adb forward'
-
-This is expected (due to a bug on old Android versions, see [#5]), but in that

-
-This error occurs when you use several `adb` versions simultaneously. You must
-find the program using a different `adb` version, and use the same `adb` version
-everywhere.
-
-You could overwrite the `adb` binary in the other program, or ask _scrcpy_ to
-use a specific `adb` binary, by setting the `ADB` environment variable:
-
-```bash
-# in bash
-export ADB=/path/to/your/adb

-scrcpy

-
-
-### Device disconnected
-

-On Windows, you might want to force OpenGL to enable mipmapping:
-
-```
-scrcpy --render-driver=opengl

-### Issue with Wayland
-
-By default, SDL uses x11 on Linux. The [video driver] can be changed via the
-`SDL_VIDEODRIVER` environment variable:
-
-[video driver]: https://wiki.libsdl.org/FAQUsingSDL#how_do_i_choose_a_specific_video_driver
-
-```bash
-export SDL_VIDEODRIVER=wayland
-scrcpy

-
-On some distributions (at least Fedora), the package `libdecor` must be
-installed manually.

-## Command line on Windows
-
-Since v1.22, a "shortcut" has been added to directly open a terminal in the
-scrcpy directory. Double-click on `open_a_terminal_here.bat`, then type your
-command. For example:
-
-```
-scrcpy --record file.mkv
-```
-
-You could also open a terminal and go to the scrcpy folder manually:
-
- 1. Press <kbd>Windows</kbd>+<kbd>r</kbd>, this opens a dialog box.
- 2. Type `cmd` and press <kbd>Enter</kbd>, this opens a terminal.
- 3. Go to your _scrcpy_ directory, by typing (adapt the path):
-
-    ```bat
-    cd C:\Users\user\Downloads\scrcpy-win64-xxx
-    ```
-
-    and press <kbd>Enter</kbd>
- 4. Type your command. For example:
-
-    ```bat
-    scrcpy --record file.mkv
-    ```
-
-If you plan to always use the same arguments, create a file `myscrcpy.bat`
-(enable [show file extensions] to avoid confusion) in the `scrcpy` directory,
-containing your command. For example:
-
-```bat
-scrcpy --prefer-text --turn-screen-off --stay-awake
-```
-
-Then just double-click on that file.
-
-You could also edit (a copy of) `scrcpy-console.bat` or `scrcpy-noconsole.vbs`
-to add some arguments.

+
+This document will be updated frequently along with the original Readme file
+이 문서는 원어 리드미 파일의 업데이트에 따라 종종 업데이트 될 것입니다
+
+ 이 어플리케이션은 UBS ( 혹은 [TCP/IP][article-tcpip] ) 로 연결된 Android 디바이스를 화면에 보여주고 관리하는 것을 제공합니다.
+ _GNU/Linux_, _Windows_ 와 _macOS_ 상에서 작동합니다.
+ (아래 설명에서 디바이스는 안드로이드 핸드폰을 의미합니다.)

+[article-tcpip]:https://www.genymotion.com/blog/open-source-project-scrcpy-now-works-wirelessly/
+
+![screenshot](https://github.com/Genymobile/scrcpy/blob/master/assets/screenshot-debian-600.jpg?raw=true)
+
+주요 기능은 다음과 같습니다.
+
+ - **가벼움** (기본적이며 디바이스의 화면만을 보여줌)
+ - **뛰어난 성능** (30~60fps)
+ - **높은 품질** (1920×1080 이상의 해상도)

+ - **장치 설치와는 무관함** (디바이스에 설치하지 않아도 됨)
+
+[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
+
+
+## 요구사항
+
+안드로이드 장치는 최소 API 21 (Android 5.0) 을 필요로 합니다.
+
+디바이스에 [adb debugging][enable-adb]이 가능한지 확인하십시오.
+
+[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
+
+어떤 디바이스에서는, 키보드와 마우스를 사용하기 위해서 [추가 옵션][control] 이 필요하기도 합니다.
+
+[control]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323
+
+
+## 앱 설치하기
+
+
+### Linux (리눅스)
+
+리눅스 상에서는 보통 [어플을 직접 설치][BUILD] 해야합니다. 어렵지 않으므로 걱정하지 않아도 됩니다.
+
+[BUILD]:https://github.com/Genymobile/scrcpy/blob/master/BUILD.md

+
+
+### Windows (윈도우)
+
+윈도우 상에서, 간단하게 설치하기 위해 종속성이 있는 사전 구축된 아카이브가 제공됩니다 (`adb` 포함) :
+해당 파일은 Readme원본 링크를 통해서 다운로드가 가능합니다.
+ - [`scrcpy-win`][direct-win]
+
+[direct-win]: https://github.com/Genymobile/scrcpy/blob/master/README.md#windows
+
+
+[어플을 직접 설치][BUILD] 할 수도 있습니다.
+
+
+### macOS (맥 OS)
+
+이 어플리케이션은 아래 사항을 따라 설치한다면 [Homebrew] 에서도 사용 가능합니다 :
+
+[Homebrew]: https://brew.sh/
+
+```bash
+brew install scrcpy
+```
+
+`PATH` 로부터 접근 가능한 `adb` 가 필요합니다. 아직 설치하지 않았다면 다음을 따라 설치해야 합니다 :
+
+```bash
+brew cask install android-platform-tools
+```
+
+[어플을 직접 설치][BUILD] 할 수도 있습니다.
+
+
+## 실행
+
+안드로이드 디바이스를 연결하고 실행하십시오:
+
+```bash
+scrcpy
+```
+
+다음과 같이 명령창 옵션 기능도 제공합니다.
+
+```bash
+scrcpy --help
+```
+
+## 기능
+
+### 캡쳐 환경 설정
+
+
+###사이즈 재정의
+
+가끔씩 성능을 향상시키기위해 안드로이드 디바이스를 낮은 해상도에서 미러링하는 것이 유용할 때도 있습니다.
+
+너비와 높이를 제한하기 위해 특정 값으로 지정할 수 있습니다 (e.g. 1024) :
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # 축약 버전
+```
+
+이 외의 크기도 디바이스의 가로 세로 비율이 유지된 상태에서 계산됩니다.
+이러한 방식으로 디바이스 상에서 1920×1080 는 모니터 상에서1024×576로 미러링될 것 입니다.
+
+
+### bit-rate 변경
+
+기본 bit-rate 는 8 Mbps입니다. 비디오 bit-rate 를 변경하기 위해선 다음과 같이 입력하십시오 (e.g. 2 Mbps로 변경):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # 축약 버전
+```
+
+###프레임 비율 제한
+
+안드로이드 버전 10이상의 디바이스에서는, 다음의 명령어로 캡쳐 화면의 프레임 비율을 제한할 수 있습니다:
+
+```bash
+scrcpy --max-fps 15
+```
+
+
+### Crop (잘라내기)
+
+디바이스 화면은 화면의 일부만 미러링하기 위해 잘라질 것입니다.
+
+예를 들어, *Oculus Go* 의 한 쪽 눈만 미러링할 때 유용합니다 :
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 1224x1440 at offset (0,0)
+scrcpy -c 1224:1440:0:0       # 축약 버전
+```
+
+만약 `--max-size` 도 지정하는 경우, 잘라낸 다음에 재정의된 크기가 적용될 것입니다.
+
+
+### 화면 녹화
+
+미러링하는 동안 화면 녹화를 할 수 있습니다 :
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+녹화하는 동안 미러링을 멈출 수 있습니다 :
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# Ctrl+C 로 녹화를 중단할 수 있습니다.
+# 윈도우 상에서 Ctrl+C 는 정상정으로 종료되지 않을 수 있으므로, 디바이스 연결을 해제하십시오.
+```
+
+"skipped frames" 은 모니터 화면에 보여지지 않았지만 녹화되었습니다 ( 성능 문제로 인해 ). 프레임은 디바이스 상에서 _타임 스탬프 ( 어느 시점에 데이터가 존재했다는 사실을 증명하기 위해 특정 위치에 시각을 표시 )_ 되었으므로, [packet delay
+variation] 은 녹화된 파일에 영향을 끼치지 않습니다.
+
+[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+## 연결
+
+### 무선연결
+
+_Scrcpy_ 장치와 정보를 주고받기 위해 `adb` 를 사용합니다.  `adb` 는 TCIP/IP 를 통해 디바이스와 [연결][connect] 할 수 있습니다 :
+
+1. 컴퓨터와 디바이스를 동일한 Wi-Fi 에 연결합니다.
+2. 디바이스의 IP address 를 확인합니다 (설정 → 내 기기 → 상태 / 혹은 인터넷에 '내 IP'검색 시 확인 가능합니다. ).
+3. TCP/IP 를 통해 디바이스에서 adb 를 사용할 수 있게 합니다: `adb tcpip 5555`.
+4. 디바이스 연결을 해제합니다.
+5. adb 를 통해 디바이스에 연결을 합니다\: `adb connect DEVICE_IP:5555` _(`DEVICE_IP` 대신)_.
+6. `scrcpy` 실행합니다.
+
+다음은 bit-rate 와 해상도를 줄이는데 유용합니다 :
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # 축약 버전
+```
+
+[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+
+### 여러 디바이스 사용 가능
+
+만약에 여러 디바이스들이 `adb devices` 목록에 표시되었다면, _serial_ 을 명시해야합니다:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # 축약 버전
+```
+
+_scrcpy_ 로 여러 디바이스를 연결해 사용할 수 있습니다.
+
+
+#### SSH tunnel
+
+떨어져 있는 디바이스와 연결하기 위해서는, 로컬 `adb` client와 떨어져 있는 `adb` 서버를 연결해야 합니다.  (디바이스와 클라이언트가 동일한 버전의 _adb_ protocol을 사용할 경우에 제공됩니다.):
+
+```bash
+adb kill-server    # 5037의 로컬 local adb server를 중단
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# 실행 유지
+```
+
+다른 터미널에서는 :
+
+```bash
+scrcpy
+```
+
+무선 연결과 동일하게, 화질을 줄이는 것이 나을 수 있습니다:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+## Window에서의 배치
+
+### 맞춤형 window 제목
+
+기본적으로, window의 이름은 디바이스의 모델명 입니다.
+다음의 명령어를 통해 변경하세요.
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+
+### 배치와 크기
+
+초기 window창의 배치와 크기는 다음과 같이 설정할 수 있습니다:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+
+### 경계 없애기
+
+윈도우 장식(경계선 등)을 다음과 같이 제거할 수 있습니다:
+
+```bash
+scrcpy --window-borderless
+```
+
+### 항상 모든 윈도우 위에 실행창 고정
+
+이 어플리케이션의 윈도우 창은 다음의 명령어로 다른 window 위에 디스플레이 할 수 있습니다:
+
+```bash
+scrcpy --always-on-top
+scrcpy -T  # 축약 버전
+```
+
+### 전체 화면
+
+이 어플리케이션은 전체화면으로 바로 시작할 수 있습니다.
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # short version
+```
+
+전체 화면은  `Ctrl`+`f`키로 끄거나 켤 수 있습니다.
+
+
+## 다른 미러링 옵션
+
+### 읽기 전용(Read-only)
+
+권한을 제한하기 위해서는 (디바이스와 관련된 모든 것: 입력 키, 마우스 이벤트 , 파일의 드래그 앤 드랍(drag&drop)):
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+### 화면 끄기
+
+미러링을 실행하는 와중에 디바이스의 화면을 끌 수 있게 하기 위해서는
+다음의 커맨드 라인 옵션을(command line option) 입력하세요:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+혹은 `Ctrl`+`o`을 눌러 언제든지 디바이스의 화면을 끌 수 있습니다.
+
+다시 화면을 켜기 위해서는`POWER` (혹은 `Ctrl`+`p`)를 누르세요.
+
+
+### 유효기간이 지난 프레임 제공 (Render expired frames)
+
+디폴트로, 대기시간을 최소화하기 위해 _scrcpy_ 는 항상 마지막으로 디코딩된 프레임을 제공합니다
+과거의 프레임은 하나씩 삭제합니다.
+
+모든 프레임을 강제로 렌더링하기 위해서는 (대기 시간이 증가될 수 있습니다)
+다음의 명령어를 사용하세요:
+
+```bash
+scrcpy --render-expired-frames
+```
+
+
+### 화면에 터치 나타내기
+
+발표를 할 때, 물리적인 기기에 한 물리적 터치를 나타내는 것이 유용할 수 있습니다.
+
+안드로이드 운영체제는 이런 기능을 _Developers options_에서 제공합니다.
+
+_Scrcpy_ 는 이런 기능을 시작할 때와 종료할 때 옵션으로 제공합니다.
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+화면에 _물리적인 터치만_ 나타나는 것에 유의하세요 (손가락을 디바이스에 대는 행위).
+
+
+### 입력 제어
+
+#### 복사-붙여넣기
+
+컴퓨터와 디바이스 양방향으로 클립보드를 복사하는 것이 가능합니다:
+
+ - `Ctrl`+`c` 디바이스의 클립보드를 컴퓨터로 복사합니다;
+ - `Ctrl`+`Shift`+`v` 컴퓨터의 클립보드를 디바이스로 복사합니다;
+ - `Ctrl`+`v` 컴퓨터의 클립보드를 text event 로써 _붙여넣습니다_  ( 그러나, ASCII 코드가 아닌 경우 실행되지 않습니다 )
+
+#### 텍스트 삽입 우선 순위
+
+텍스트를 입력할 때 생성되는 두 가지의 [events][textevents] 가 있습니다:
+ - _key events_, 키가 눌려있는 지에 대한 신호;
+ - _text events_, 텍스트가 입력되었는지에 대한 신호.
+
+기본적으로, 글자들은 key event 를 이용해 입력되기 때문에, 키보드는 게임에서처럼 처리합니다 ( 보통 WASD 키에 대해서 ).
+
+그러나 이는 [issues 를 발생][prefertext]시킵니다. 이와 관련된 문제를 접할 경우, 아래와 같이 피할 수 있습니다:
+
+```bash
+scrcpy --prefer-text
+```
+
+( 그러나 이는 게임에서의 처리를 중단할 수 있습니다 )
+

+
+
+### 파일 드랍
+
+### APK 실행하기
+
+APK를 실행하기 위해서는, APK file(파일명이`.apk`로 끝나는 파일)을  드래그하고 _scrcpy_ window에 드랍하세요 (drag and drop)
+
+시각적인 피드백은 없고,log 하나가 콘솔에 출력될 것입니다.
+
+### 디바이스에 파일 push하기
+
+디바이스의`/sdcard/`에 파일을 push하기 위해서는,
+APK파일이 아닌 파일을_scrcpy_ window에 드래그하고 드랍하세요.(drag and drop).
+
+시각적인 피드백은 없고,log 하나가 콘솔에 출력될 것입니다.
+
+해당 디렉토리는 시작할 때 변경이 가능합니다:
+
+```bash
+scrcpy --push-target /sdcard/foo/bar/
+```
+
+### 오디오의 전달
+
+_scrcpy_는 오디오를 직접 전달해주지 않습니다. [USBaudio] (Linux-only)를 사용하세요.
+
+추가적으로 [issue #14]를 참고하세요.

+## _scrcpy_ 인 이유?
+
+한 동료가 [gnirehtet]와 같이 발음하기 어려운 이름을 찾을 수 있는지 도발했습니다.
+
+[`strcpy`] 는 **str**ing을 copy하고; `scrcpy`는 **scr**een을 copy합니다.

-/* The representation of input events in scrcpy is very close to the SDL API,
- * for simplicity.
- *
- * This scrcpy input events API is designed to be consumed by input event
- * processors (sc_key_processor and sc_mouse_processor, see app/src/trait/).
- *
- * One major semantic difference between SDL input events and scrcpy input
- * events is their frame of reference (for mouse and touch events): SDL events
- * coordinates are expressed in SDL window coordinates (the visible UI), while
- * scrcpy events are expressed in device frame coordinates.
- *
- * In particular, the window may be visually scaled or rotated (with --rotation
- * or MOD+Left/Right), but this does not impact scrcpy input events (contrary
- * to SDL input events). This allows to abstract these display details from the
- * input event processors (and to make them independent from the "screen").
- *
- * For many enums below, the values are purposely the same as the SDL
- * constants (though not all SDL values are represented), so that the
- * implementation to convert from the SDL version to the scrcpy version is
- * straightforward.
- *
- * In practice, there are 3 levels of input events:
- *  1. SDL input events (as received from SDL)
- *  2. scrcpy input events (this API)
- *  3. the key/mouse processors input events (Android API or HID events)
- *
- * An input event is first received (1), then (if accepted) converted to an
- * scrcpy input event (2), then submitted to the relevant key/mouse processor,
- * which (if accepted) is converted to an Android event (to be sent to the
- * server) or to an HID event (to be sent over USB/AOA directly).
