scrcpy 1.13 is released, improves the display quality, provides the option to lock the video direction, more

script 1.13 has been released, with some important new features, including options for locking the video direction, shortcuts for rotating the display, and tri-linear filtering. When the scrcpy window is much smaller than the Android device display, tri-linear filtering should improve the display quality.
Are you new to scrcpy? This application can be used to display, record and control Android devices connected via USB or wirelessly from the macOS, Windows or Linux desktop. The application focuses on performance and quality, providing 30~60 FPS, a resolution of 1920×1080 or higher, and low latency.
The communication between the server (in this case, the Android device) and the client (desktop computer) is through a socket over the adb tunnel. The server streams the H.264 video of the device screen and passes it to the client to decode and display it without buffering to minimize delay. Mouse and keyboard events are captured and transmitted to the server, and the server injects them into the Android device.
It is important to note that audio forwarding does not work, which is a limitation of the Android Open Accessory Protocol.
After adding the function of switching between portrait and landscape mode without changing the phone orientation in the previous version, ( Ctrl + r), scrcpy 1.13 adds two new direction-related options: an option for locking the video direction, and a shortcut for rotating the display in 90° steps. To lock the video direction, use:

  • Natural direction:
scrcpy --lock-video-orientation 0 
  • 90° counterclockwise:
scrcpy --lock-video-orientation 1
  • 180°:
scrcpy --lock-video-orientation 2
  • Rotate 90° clockwise:
scrcpy --lock-video-orientation 3

To change the display rotation, you can use keyboard shortcuts. Use the following buttons to rotate the display 90° counterclockwise Ctrl + ←And then use Ctrl + →.
It is worth noting that this will only affect the display, and the record will not be affected. Another important new feature of scrcpy 1.13 is trilinear filtering. Before this version, if the scrcpy window is much smaller than the Android device display, the visual quality will be low. However, with this release, the quality in this case should be better.
This is a screenshot of the scrcpy 1.13 release notes (I haven’t taken it), showing the quality before and after:scrcpy trilinear filteringPlease note that this degradation (trilinear filtering) requires OpenGL 3.0+ or ​​OpenGL ES 2.0+, so it is not available in all places. This feature is not supported on macOS. On Windows, you need to force the use of OpenGL instead of Direct3D by starting scrcpy with the following command:

scrcpy --render-driver=opengl

If you want to disable this feature when it is automatically enabled (on Linux), use the following command to start scrcpy --no-mipmaps.
More changes in scrcpy 1.13:

  • Add the function of mirroring the secondary display, for example when using Samsung DeX. This is done with the new logo --display 1. The secondary display can only be controlled if the device is running at least Android 10. In addition, sometimes the second display shows a black screen, and there is currently no known solution.
  • Added option to change the capture FPS for Android versions prior to 10 (--max-fps)
  • The window position value can now be negative (--window-x with --window-y), this should help when placing windows on a setup with multiple monitors
  • If 27183 is not available, please use another local port (you can now specify a port range, for example -p 27183:27186). This should be able to connect and display 2 or more Android devices wirelessly at the same time
  • Forward NumPad keys when NumLock is disabled
  • Fix the problem when the directory contains non-ASCII characters on Windows
  • Fix possible BufferUnderflowException in touch events
  • Upgrade FFmpeg to 4.2.2 in Windows version and upgrade SDL to 2.0.12
