If --no-control is set, then the controller is not initialized (both in
the client and the server), so it is not possible to control the device
to turn its screen off.
See <https://github.com/Genymobile/scrcpy/issues/608>.
In portable builds, scrcpy-server.jar was supposed to be present in the
current directory, so in practice it worked only if scrcpy was launched
from its own directory.
Instead, find the absolute path of the executable and build a suitable
path to use scrcpy-server.jar from the same directory.
There was already utf8_to_wide_char(), used to correctly execute
commands on Windows.
Add the reverse converter: utf8_from_wide_char(). We will need it to
build the scrcpy-server path based on the executable directory.
To create a portable build (with scrcpy-server.jar accessible from the
scrcpy directory), replace OVERRIDE_SERVER_PATH by a simple compilation
flag: PORTABLE.
This paves the way to use more complex rules to determine the path of
scrcpy-server.jar in portable builds.
On socket disconnection, on Linux, recv() returns -1 and errno is set.
But on Windows, errno is 0.
In that case, AVERROR(errno) == 0, leading to the warning:
> Invalid return value 0 for stream protocol
To avoid the problem, if errno is 0, return AVERROR_EOF.

The FPS counter was called only on new frames, so it could not print
values regularly, especially when there are very few FPS (when the
device surface does not change).
To the extreme, it was never able to display 0 fps.
Add a separate thread to print framerate every second.
Only keep "turn device screen off" and POWER button.
After we turn the device screen off (with Ctrl+o), turning it back on
does not always work, and leaves the device in a weird state, where even
the power button may not be sufficient:
<https://github.com/Genymobile/scrcpy/issues/175#issuecomment-497946596>
This is not an acceptable behavior, so disable the shortcut to turn the
physical device screen on. We can use the POWER button (or Ctrl+p)
instead.
The condition "event->type == SDL_KEYDOWN" and the variable
input_manager->controller are used many times. Replace them by local
variables to reduce verbosity.
Add two shortcuts:
- Ctrl+o to turn the device screen off while mirroring
- Ctrl+Shift+o to turn it back on
On power on (either via the POWER key or BACK while screen is off), both
the device screen and the mirror are turned on.

After the recent refactorings, a "control event" is not necessarily an
"event" (it may be a "command"). Similarly, the unique "device event"
used to send the device clipboard content is more a "reponse" to the
request from the client than an "event".
Rename both to "message", and rename the message types to better
describe their intent.
It was already possible to _paste_ (with Ctrl+v) the content of the
computer clipboard on the device. Technically, it injects a sequence of
events to generate the text.
Add a new feature (Ctrl+Shift+v) to copy to the device clipboard
instead, without injecting the content. Contrary to events injection,
this preserves the UTF-8 content exactly, so the text is not broken by
special characters.
<https://github.com/Genymobile/scrcpy/issues/413>
On Ctrl+C:
- the client sends a GET_CLIPBOARD command to the device;
- the device retrieve its current clipboard text and sends it in a
GET_CLIPBOARD device event;
- the client sets this text as the system clipboard text, so that it
can be pasted in another application.
Fixes <https://github.com/Genymobile/scrcpy/issues/145>
The socket used the device-to-computer direction to stream the video and
the computer-to-device direction to send control events.
Some features, like copy-paste from device to computer, require to send
non-video data from the device to the computer.
To make them possible, use two sockets:
- one for streaming the video from the device to the client;
- one for control/events in both directions.
A string is serialized as a length (2 bytes) followed by the string data
(non nul-terminated).
For now, it is used only once, but we will need to serialize strings in
other events.
Several commands were grouped under the same event type "command", with
a separate field to indicate the actual command.
Move these commands at the same level as other control events. It will
allow to implement commands with arguments.
The cleanup is not linear: for example, the server must be stopped and
its sockets must be shutdown after the stream and controller are stopped
(so that they don't continue processing garbage), but before they are
joined, to avoid a deadlock if they are blocked on a socket read.
Simplify the spaghetti-cleanup by keeping trace of initialization at
runtime.
Compositor bypass is meant for fullscreen games consuming lots of GPU
resources. For a light app that will usually be windowed, this only
causes unnecessary compositor suspends, especially visible (and
annoying) with complying window manager like KWin.

The serialized text is not nul-terminated (its size is explicitely
provided), but the input text in the event is a nul-terminated string.
The test was failing with ASAN enabled.
Replace the "global" control flag in the input_manager by a function
parameter to make explicit that the behavior depends whether
--no-control has been set.
The SDL video subsystem is not necessary if we don't display the video.
Move the sdl_init_and_configure() function from screen.c to scrcpy.c,
because it is not only related to the screen display.
The function video_buffer_offer_decoded_frame() returned a bool to
indicate whether the previous frame had been consumed.
This was confusing, because we could expect the returned bool report
whether the action succeeded.
Make the semantic explicit by using an output parameter.
Also revert the flag (report if the frame has been skipped instead of
consumed) to avoid confusion for the first frame (the previous is
neither skipped nor consumed because there is no previous frame).
The description of scrcpy is "Display and control your Android device".
We want an option to disable display, another one to disable control.
For naming consistency, name it --no-display.
Also change the shortname to -N, so that we can use -n for --no-control
later.
Limit source code to 80 chars, and declare functions return type and
modifiers on a separate line.
This allows to avoid very long lines, and all function names are
aligned.
(We do this on VLC, and I like it.)
