The Callbacks interface notifies new packets. But in addition, the
screen encoder will need to write headers on start.
We could add a function onStart(), but for simplicity, just remove the
interface, which brings no value, and call the streamer directly.

On any error, all previously opened sockets must be closed.
Handle these errors in a single catch-block. Currently, there are only 2
sockets, but this will simplify even more with more sockets.
Note: this commit is better displayed with --ignore-space-change (-b).
User-friendly error messages are printed on specific configuration
exceptions. In that case, do not print the stacktrace.
Also handle the user-friendly error message directly where the error
occurs, and print multiline messages in a single log call, to avoid
confusing interleaving.

DesktopConnection implements Closeable, so it is implicitly closed after
its try-with-resources block. Closing the DesktopConnection shutdowns
the sockets, so it is necessary in particular to wake up blocking read()
calls from the controller.
But the controller thread was joined before the DesktopConnection was
closed, causing a deadlock. To fix the problem, join the controller
thread only after the DesktopConnection is closed.

On close, the client closes the socket. This wakes up socket blocking
calls on the server-side, by throwing an exception. Since this exception
is expected, it was not logged.
However, other IOExceptions might occur, which must not be ignored. For
that purpose, log only IOException when they are not caused by an EPIPE
error.
The PTS received from MediaCodec are expressed relative to an arbitrary
clock origin. We consider the PTS of the first frame to be 0, and the
PTS of every other frame is relative to this first PTS (note that the
PTS is only used for recording, it is ignored for mirroring).
For simplicity, this relative PTS was computed on the server-side.
To prepare support for multiple stream (video and audio), send the
packet with its original PTS, and handle the PTS offset on the
client-side (by the recorder).
Since we can't know in advance which stream will produce the first
packet with the lowest PTS (a packet received later on one stream may
have a PTS lower than a packet received earlier on another stream),
computing the PTS on the server-side would require unnecessary waiting.
On mouse click events:
- the first button pressed must first generate ACTION_DOWN;
- all button pressed (including the first one) must generate
ACTION_BUTTON_PRESS;
- all button released (including the last one) must generate
ACTION_BUTTON_RELEASE;
- the last button released must in addition generate ACTION_UP.
Otherwise, Chrome does not work properly.

MediaCodec may fail spuriously, typically when stopping an encoding and
starting a new one immediately (for example on device rotation).
In that case, retry a few times, in many cases it should work.
Refs #3693 <https://github.com/Genymobile/scrcpy/issues/3693>
For the initial connection between the device and the computer, an adb
tunnel is established (with "adb reverse" or "adb forward").
The device-side of the tunnel is a local socket having the hard-coded
name "scrcpy". This may cause issues when several scrcpy instances are
started in a few seconds for the same device, since they will try to
bind the same name.
To avoid conflicts, make the client generate a random UID, and append
this UID to the local socket name ("scrcpy_01234567").
Right click and middle click require the source device to be a mouse,
not a touchscreen. Therefore, the source device was changed only when a
button other than the primary button was pressed (see
adc547fa6e).
However, this led to inconsistencies between the ACTION_DOWN when a
secondary button is pressed (with a mouse as source device) and the
matching ACTION_UP when the secondary button is released (with a
touchscreen as source device, because then there is no button pressed).
To avoid the problem in all cases, force a mouse as source device when
--forward-all-clicks is set.
Concretely, for mouse events in --forward-all-clicks mode:
- device source is set to InputDevice.SOURCE_MOUSE;
- motion event toolType is set to MotionEvent.TOOL_TYPE_MOUSE;
Otherwise (when --forward-all-clicks is unset, or for real touch
events), finger events are injected:
- device source is set to InputDevice.SOURCE_TOUCHSCREEN;
- motion event toolType is set to MotionEvent.TOOL_TYPE_FINGER.

There were exactly one instance of ServiceManager and Settings, stored
in Device.
Since a Device instance is not created by the CleanUp executable, it was
not straightforward to call wrapper methods on cleanup.
Remove this artificial restriction and expose them publicly via static
methods (this is equivalent to expose a singleton, but less verbose).
The previous commit replaced the IInterface instance (the "input"
service) by the InputManager instance (retrieved by
InputManager.getInstance()).
Both define an "injectInputEvent" method, but the alternate version
(probably) does not concern the InputManager.
This reverts commit b7a06278fe.
PR #3190 <https://github.com/Genymobile/scrcpy/pull/3190>
A special PTS value was used to encode a config packet.
To prepare for adding more flags, use the most significant bits of the
PTS field to store flags.
The new retry mechanism with a lower definition only worked if the error
occurred during encode(). For example:
java.lang.IllegalStateException
at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method)
at android.media.MediaCodec.dequeueOutputBuffer(MediaCodec.java:3452)
at com.genymobile.scrcpy.ScreenEncoder.encode(ScreenEncoder.java:114)

at com.genymobile.scrcpy.Server.scrcpy(Server.java:80)
at com.genymobile.scrcpy.Server.main(Server.java:255)
However, MediaCodec may also fail before encoding, during configure() or
start(). For example:
android.media.MediaCodec$CodecException: Error 0xfffffc0e
at android.media.MediaCodec.native_configure(Native Method)
at android.media.MediaCodec.configure(MediaCodec.java:1956)
at android.media.MediaCodec.configure(MediaCodec.java:1885)

For convenience, this new option forces the 3 following options:
- send_device_meta=false
- send_frame_meta=false
- send_dummy_byte=false
This allows to send a raw H.264 stream on the video socket.
Concretely:
adb push scrcpy-server /data/local/tmp/scrcpy-server.jar
adb forward tcp:1234 localabstract:scrcpy
adb shell CLASSPATH=/data/local/tmp/scrcpy-server.jar \
app_process / com.genymobile.scrcpy.Server 1.21 \

As soon as a client connects via TCP to localhost:1234, it will receive
the raw H.264 stream.

Retry with a lower definition if MediaCodec fails before the first
frame, not the first packet.
In practice, the first packet is a config packet without any frame, and
MediaCodec might fail just after.
Refs 2eb6fe7d81
Refs #2963 <https://github.com/Genymobile/scrcpy/issues/2963>
MediaCodec errors always trigger IllegalStateException or a subtype
(like MediaCodec.CodecException).
In practice, this avoids to retry if the error is caused by an
IOException when writing the video packet to the socket.
The purpose of automatic downscaling on error is to make mirroring work
by just starting scrcpy without an explicit -m value, even if the
encoder could not encode at the screen definition.
It is only useful when we detect an encoding failure before the first
frame. Downsizing later could be surprising, so disable it.
PR #2947 <https://github.com/Genymobile/scrcpy/pull/2947>
Now that scrcpy attempts with a lower definition on any MediaCodec
error (or the user explicitly requests to disable auto-downsizing), the
suggestion is unnecessary.

A scroll event might be produced when a mouse button is pressed (for
example when scrolling while selecting a text). For consistency, pass
the actual buttons state (instead of 0).
In practice, it seems that this use case does not work properly with
Android event injection, but it will work with HID mouse.
If --no-control is enabled, then it is not necessary to create a second
communication socket between the client and the server.
This also facilitates the use of the server alone (without the client)
to receive only the raw video stream.
Expose the inject input event mode so that it is possible to wait for
the events to be "finished". This will be necessary to read the
clipboard content only after the COPY or CUT key event is handled.
PR #2834 <https://github.com/Genymobile/scrcpy/pull/2834>
The options values to configure the server were identified by their
command-line argument index. Now that there are a lot of arguments, many
of them being booleans, it became unreadable and error-prone.
Identify the arguments by a key string instead, and make them optional.
This will also simplify running the server manually for debugging.
Cleanup is used for some options like --show-touches to restore the
state on exit.
If the configuration fails, do not crash the whole process. Just log an
error.
PR #2802 <https://github.com/Genymobile/scrcpy/pull/2802>
Before Android 8, executing the "settings" command from a shell was
very slow (~1 second), because it spawned a new app_process to execute
Java code. Therefore, to access settings without performance issues,
scrcpy used private APIs to read from and write to settings.
However, since Android 12, this is not possible anymore, due to
permissions changes.
To make it work again, execute the "settings" command on Android 12 (or
on previous version if the other method failed). This method is faster
than before Android 8 (~100ms).

Make the versionCode a decimal representation of the scrcpy version.
This will for example allow to correctly number the versionCode of
v1.17.1 after a v1.18 is released:
- v1.18 -> 11800
- v1.17.1 -> 11701
- v1.18.1 -> 11801
Remove useless intermediate method with a "mode" parameter (it's always
called with the same mode).
This also avoids the need for a specific injectEventOnDisplay() method,
since it does not conflict with another injectEvent() method anymore.
Add a new mode to the --lock-video-orientation option, to lock the
initial orientation of the device.
This avoids to pass an explicit value (0, 1, 2 or 3) and think about
which is the right one.
The collapsing action collapses any panels.
By the way, the Android method is named collapsePanels().

The shortcut "back on screen on" is a bit special: the control is
requested by the client, but the actual event injection (POWER or BACK)
is determined on the device.
To properly inject DOWN and UP events for BACK, transmit the action as
a control parameter.
If the screen is off:
- on DOWN, inject POWER (DOWN and UP) (wake up the device immediately)
- on UP, do nothing
If the screen is on:
- on DOWN, inject BACK DOWN
- on UP, inject BACK UP
A corner case is when the screen turns off between the DOWN and UP
event. In that case, a BACK UP event will be injected, so it's harmless.
As a consequence of this change, the BACK button is now handled by
Android on mouse released. This is consistent with the keyboard shortcut
(Mod+b) behavior.

This commit in AOSP framework_base added a parameter "attributionTag" to
the call() method:
12ac3f406f%5E%21/#F17
As a consequence, the method did not exist, so scrcpy used the legacy
call() method (using the authority "unknown") as a fallback, which fails
for security reasons.
Fixes#1468 <https://github.com/Genymobile/scrcpy/issues/1468>
The behavior of some methods do not depend on the user-provided options.
These methods can be static. This will allow to call them directly from
the cleanup process.
To avoid possible copy-paste loops between the computer and the device,
the device clipboard is not set if it already contains the expected
content.
But the condition was wrong: it was not set also if it was empty.
Refs 1223a72eb8Fixes#1658 <https://github.com/Genymobile/scrcpy/issues/1658>
Do not explicitly set the clipboard text if it already contains the
expected content. This avoids possible copy-paste loops between the
computer and the device.
When the client requests to set the clipboard, it may request to press
the PASTE key in addition. To be a bit generic, it was stored as a flag
in ControlMessage.java.
But flags suggest that it represents a bitwise union. Use a simple
boolean instead.
To power the device on, inject KEYCODE_WAKEUP to avoid a possible
race condition (the device might become off between the test
isScreenOn() and the POWER keycode injection).
In theory, this was expected to only happen when a touch event is sent
just before the device is rotated, but some devices do not respect the
encoding size, causing an unexpected mismatch.
Refs #1518 <https://github.com/Genymobile/scrcpy/issues/1518>
In practice, it does not change anything (it just avoids a spurious
wake-up), but semantically, it makes no sense to call
pushClipboardText() with a null value.
Clean up has been broken by 3df63c579d.
The verbosity was correctly initialized for the Server process, but not
for the CleanUp process.
To avoid the problem, initialize a default log level.
Only the main injection method was exposed on Device, the convenience
methods were implemented in Controller.
For consistency, move them all to the Device class.
The Android device listens for clipboard changes to synchronize with the
computer clipboard.
However, if the change comes from scrcpy (for example via Ctrl+Shift+v),
do not notify the change.
Scroll events were sent with a mouse input device. When scrolling on a
list, this could cause the whole list to be focused, and drawn with the
focus color as background.
Send scroll events with a touchscreen input device instead (like motion
