This flag forced the decoder to wait for the previous frame to be
consumed by the display.
It was initially implemented as a compilation flag for testing, not
intended to be exposed at runtime. But to remove ifdefs and to allow
users to test this flag easily, it had finally been exposed by commit
ebccb9f6cc.
In practice, it turned out to be useless: it had no practical impact,
and it did not solve or mitigate any performance issues causing frame
skipping.
But that added some complexity to the codebase: it required an
additional condition variable, and made video buffer calls possibly
blocking, which in turn required code to interrupt it on exit.
To prepare support for multiple sinks plugged to the decoder (display
and v4l2 for example), the blocking call used for pacing the decoder
output becomes unacceptable, so just remove this useless "feature".

.SH NAME
|
|
scrcpy \- Display and control your Android device
|
|
|
|
|
|
.SH SYNOPSIS
|
|
.B scrcpy
|
|
.RI [ options ]
|
|
|
|
|
|
.SH DESCRIPTION
|
|
.B scrcpy
|
|
provides display and control of Android devices connected on USB (or over TCP/IP). It does not require any root access.
|
|
|
|
|
|
.SH OPTIONS
|
|
|
|
.TP
|
|
.B \-\-always\-on\-top
|
|
Make scrcpy window always on top (above other windows).
|
|
|
|
.TP
|
|
.BI "\-b, \-\-bit\-rate " value
|
|
Encode the video at the given bit\-rate, expressed in bits/s. Unit suffixes are supported: '\fBK\fR' (x1000) and '\fBM\fR' (x1000000).
|
|
|
|
Default is 8000000.
|
|
|
|
.TP
|
|
.BI "\-\-codec\-options " key[:type]=value[,...]
|
|
Set a list of comma-separated key:type=value options for the device encoder.
|
|
|
|
The possible values for 'type' are 'int' (default), 'long', 'float' and 'string'.
|
|
|
|
The list of possible codec options is available in the Android documentation
|
|
.UR https://d.android.com/reference/android/media/MediaFormat
|
|
.UE .
|
|
|
|
.TP
|
|
.BI "\-\-crop " width\fR:\fIheight\fR:\fIx\fR:\fIy
|
|
Crop the device screen on the server.
|
|
|
|
The values are expressed in the device natural orientation (typically, portrait for a phone, landscape for a tablet). Any
|
|
.B \-\-max\-size
|
|
value is computed on the cropped size.
|
|
|
|
.TP
|
|
.BI "\-\-disable-screensaver"
|
|
Disable screensaver while scrcpy is running.
|
|
|
|
.TP
|
|
.BI "\-\-display " id
|
|
Specify the display id to mirror.
|
|
|
|
The list of possible display ids can be listed by "adb shell dumpsys display"
|
|
(search "mDisplayId=" in the output).
|
|
|
|
Default is 0.
|
|
|
|
.TP
|
|
.BI "\-\-encoder " name
|
|
Use a specific MediaCodec encoder (must be a H.264 encoder).
|
|
|
|
.TP
|
|
.B \-\-force\-adb\-forward
|
|
Do not attempt to use "adb reverse" to connect to the device.
|
|
|
|
.TP
|
|
.B \-\-forward\-all\-clicks
|
|
By default, right-click triggers BACK (or POWER on) and middle-click triggers HOME. This option disables these shortcuts and forward the clicks to the device instead.
|
|
|
|
.TP
|
|
.B \-f, \-\-fullscreen
|
|
Start in fullscreen.
|
|
|
|
.TP
|
|
.B \-h, \-\-help
|
|
Print this help.
|
|
|
|
.TP
|
|
.B \-\-legacy\-paste
|
|
Inject computer clipboard text as a sequence of key events on Ctrl+v (like MOD+Shift+v).
|
|
|
|
This is a workaround for some devices not behaving as expected when setting the device clipboard programmatically.
|
|
|
|
.TP
|
|
.BI "\-\-lock\-video\-orientation " value
|
|
Lock video orientation to \fIvalue\fR. Possible values are -1 (unlocked), 0, 1, 2 and 3. Natural device orientation is 0, and each increment adds a 90 degrees otation counterclockwise.
|
|
|
|
Default is -1 (unlocked).
|
|
|
|
.TP
|
|
.BI "\-\-max\-fps " value
|
|
Limit the framerate of screen capture (officially supported since Android 10, but may work on earlier versions).
|
|
|
|
.TP
|
|
.BI "\-m, \-\-max\-size " value
|
|
Limit both the width and height of the video to \fIvalue\fR. The other dimension is computed so that the device aspect\-ratio is preserved.
|
|
|
|
Default is 0 (unlimited).
|
|
|
|
.TP
|
|
.B \-n, \-\-no\-control
|
|
Disable device control (mirror the device in read\-only).
|
|
|
|
.TP
|
|
.B \-N, \-\-no\-display
|
|
Do not display device (only when screen recording is enabled).
|
|
|
|
.TP
|
|
.B \-\-no\-key\-repeat
|
|
Do not forward repeated key events when a key is held down.
|
|
|
|
.TP
|
|
.B \-\-no\-mipmaps
|
|
If the renderer is OpenGL 3.0+ or OpenGL ES 2.0+, then mipmaps are automatically generated to improve downscaling quality. This option disables the generation of mipmaps.
|
|
|
|
.TP
|
|
.BI "\-p, \-\-port " port[:port]
|
|
Set the TCP port (range) used by the client to listen.
|
|
|
|
Default is 27183:27199.
|
|
|
|
.TP
|
|
.B \-\-prefer\-text
|
|
Inject alpha characters and space as text events instead of key events.
|
|
|
|
This avoids issues when combining multiple keys to enter special characters,
|
|
but breaks the expected behavior of alpha keys in games (typically WASD).
|
|
|
|
.TP
|
|
.BI "\-\-push\-target " path
|
|
Set the target directory for pushing files to the device by drag & drop. It is passed as\-is to "adb push".

.TP
|
|
.BI "\-r, \-\-record " file
|
|
Record screen to
|
|
.IR file .
|
|
|
|
The format is determined by the
|
|
.B \-\-record\-format
|
|
option if set, or by the file extension (.mp4 or .mkv).
|
|
|
|
.TP
|
|
.BI "\-\-record\-format " format
|
|
Force recording format (either mp4 or mkv).
|
|
|
|
.TP
|
|
