+# 자주하는 질문 (FAQ)
+
+다음은 자주 제보되는 문제들과 그들의 현황입니다.
+
+
+### Window 운영체제에서, 디바이스가 발견되지 않습니다.
+
+가장 흔한 제보는 `adb`에 발견되지 않는 디바이스 혹은 권한 관련 문제입니다.
+다음 명령어를 호출하여 모든 것들에 이상이 없는지 확인하세요:
+
+    adb devices
+
+Window는 당신의 디바이스를 감지하기 위해 [drivers]가 필요할 수도 있습니다.
+
+[drivers]: https://developer.android.com/studio/run/oem-usb.html
+
+
+### 내 디바이스의 미러링만 가능하고, 디바이스와 상호작용을 할 수 없습니다.
+
+일부 디바이스에서는, [simulating input]을 허용하기 위해서 한가지 옵션을 활성화해야 할 수도 있습니다.
+개발자 옵션에서 (developer options) 다음을 활성화 하세요:
+
+> **USB debugging (Security settings)**
+> _권한 부여와 USB 디버깅을 통한 simulating input을 허용한다_
+
+[simulating input]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323
+
+
+### 마우스 클릭이 다른 곳에 적용됩니다.
+
+Mac 운영체제에서, HiDPI support 와 여러 스크린 창이 있는 경우, 입력 위치가 잘못 파악될 수 있습니다.
+[issue 15]를 참고하세요.
+
+[issue 15]: https://github.com/Genymobile/scrcpy/issues/15
+
+차선책은 HiDPI support을 비활성화 하고 build하는 방법입니다:
+
+```bash
+meson x --buildtype release -Dhidpi_support=false
+```
+
+하지만, 동영상은 낮은 해상도로 재생될 것 입니다.
+
+
+### HiDPI display의 화질이 낮습니다.
+
+Windows에서는, [scaling behavior] 환경을 설정해야 할 수도 있습니다.
+
+> `scrcpy.exe` > Properties > Compatibility > Change high DPI settings >
+> Override high DPI scaling behavior > Scaling performed by: _Application_.
+
+[scaling behavior]: https://github.com/Genymobile/scrcpy/issues/40#issuecomment-424466723
+
+
+### KWin compositor가 실행되지 않습니다
+
+Plasma Desktop에서는,_scrcpy_ 가 실행중에는 compositor가 비활성화 됩니다.
+
+차석책으로는, ["Block compositing"를 비활성화하세요][kwin].
+
+[kwin]: https://github.com/Genymobile/scrcpy/issues/114#issuecomment-378778613
+
+
+###비디오 스트림을 열 수 없는 에러가 발생합니다.(Could not open video stream).
+
+여러가지 원인이 있을 수 있습니다. 가장 흔한 원인은 디바이스의 하드웨어 인코더(hardware encoder)가
+주어진 해상도를 인코딩할 수 없는 경우입니다.
+
+```
+ERROR: Exception on thread Thread[main,5,main]
+android.media.MediaCodec$CodecException: Error 0xfffffc0e
+...
+Exit due to uncaughtException in main thread:
+ERROR: Could not open video stream
+INFO: Initial texture: 1080x2336
+```
+
+더 낮은 해상도로 시도 해보세요:
+
+```
+scrcpy -m 1920
+scrcpy -m 1024
+scrcpy -m 800
+```

+
+[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
+
+[Snap] 패키지가 가능합니다 : [`scrcpy`][snap-link].

+
+[snap]: https://en.wikipedia.org/wiki/Snappy_(package_manager)
+
+Arch Linux에서, [AUR] 패키지가 가능합니다 : [`scrcpy`][aur-link].
+
+[AUR]: https://wiki.archlinux.org/index.php/Arch_User_Repository
+[aur-link]: https://aur.archlinux.org/packages/scrcpy/
+
+Gentoo에서 ,[Ebuild] 가 가능합니다 : [`scrcpy/`][ebuild-link].
+
+[Ebuild]: https://wiki.gentoo.org/wiki/Ebuild
+[ebuild-link]: https://github.com/maggu2810/maggu2810-overlay/tree/master/app-mobilephone/scrcpy
+
+
+### 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 )
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+### 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.
+
