### `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

Here are the common reported problems and their status.
### 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.
In that case, it will print this error:
> ERROR: "adb push" returned with value 1
This is typically not a bug in _scrcpy_, but a problem in your environment.
To find out the cause, execute:
```bash
adb devices
```
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 unauthorized
Check [stackoverflow][device-unauthorized].
[device-unauthorized]: https://stackoverflow.com/questions/23081263/adb-android-device-unauthorized
### Device not detected
If your device is not detected, you may need some [drivers] (on Windows).
[drivers]: https://developer.android.com/studio/run/oem-usb.html
### I can only mirror, I cannot interact with the device
### Several devices connected
If several devices are connected, you will encounter this error:
> adb: error: failed to get feature set: more than one device/emulator
the identifier of the device you want to mirror must be provided:
```bash
scrcpy -s 01234567890abcdef
```
Note that if your device is connected over TCP/IP, you'll get this message:
> adb: error: more than one device/emulator
> 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
case, scrcpy fallbacks to a different method, which should work.
[#5]: https://github.com/Genymobile/scrcpy/issues/5
### Conflicts between adb versions
> adb server version (41) doesn't match this client (39); killing...
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
set ADB=/path/to/your/adb
scrcpy
```
### Device disconnected
If _scrcpy_ stops itself with the warning "Device disconnected", then the
`adb` connection has been closed.
Try with another USB cable or plug it into another USB port. See [#281] and
[#283].

A workaround is to build with HiDPI support disabled:
```bash
meson x --buildtype release -Dhidpi_support=false
```
However, the video will be displayed at lower resolution.
Open _scrcpy_ directly on the monitor you use it.
### The quality is low on HiDPI display
### Special characters do not work
Injecting text input is [limited to ASCII characters][text-input]. A trick
allows to also inject some [accented characters][accented-characters], but
that's all. See [#37].

If the definition of your client window is far smaller than that of your device
screen, then you'll get poor quality. This is especially visible on text. See

### I get an error "Could not open video stream"

There may be many reasons. One common cause is that the hardware encoder of your
device is not able to encode at the given definition:
```
