# Frequently Asked Questions
|
|
|
|
Here are the common reported problems and their status.
|
|
|
|
|
|
### On Windows, my device is not detected
|
|
|
|
The most common is your device not being detected by `adb`, or is unauthorized.
|
|
Check everything is ok by calling:
|
|
|
|
adb devices
|
|
|
|
Windows may need some [drivers] to detect your device.
|
|
|
|

|
|
|
|
|
|
### I can only mirror, I cannot interact with the device
|
|
|
|
On some devices, you may need to enable an option to allow [simulating input].
|
|
In developer options, enable:
|
|
|
|
> **USB debugging (Security settings)**
|
|
> _Allow granting permissions and simulating input via USB debugging_
|
|

|
|
### Mouse clicks at wrong location
|
|
|
|
On MacOS, with HiDPI support and multiple screens, input location are wrongly
|
|
scaled. See [issue 15].
|
|
|
|
[issue 15]: https://github.com/Genymobile/scrcpy/issues/15
|
|
|
|
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.
|
|
|
|
|
|
### The quality is low on HiDPI display
|
|
|
|
On Windows, you may need to configure the [scaling behavior].
|
|
|
|
> `scrcpy.exe` > Properties > Compatibility > Change high DPI settings >
|
|
> Override high DPI scaling behavior > Scaling performed by: _Application_.
|
|
|

|
### KWin compositor crashes
|
|
|
|
On Plasma Desktop, compositor is disabled while _scrcpy_ is running.
|
|
|
|
As a workaround, [disable "Block compositing"][kwin].
|
|

|
### 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:
|
|
|
|
```
|
|
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
|
|
```
|
|
|
|
Just try with a lower definition:
|
|
|
|
```
|
|
scrcpy -m 1920
|
|
scrcpy -m 1024
|
|
scrcpy -m 800
|
|
```
