List all USB devices in a first step, then select the matching one(s).
This allows to report a user-friendly log message containing the list of
devices, with the matching one(s) highlighted.
PR #3005 <https://github.com/Genymobile/scrcpy/pull/3005>
One log macro was provided for each log level (LOGV(), LOGD(), LOGI(),
LOGW(), LOGE()).
Add a generic macro LOG(LEVEL, ...) accepting a log level as parameter,
so that it is possible to write logging wrappers.

This util function was error-prone:
- it accepted a buffer as parameter (not necessarily a NUL-terminated
string) and its length (including the NUL char, if any);
- it wrote '\0' over the last character of the buffer, so the last
character was lost if the buffer was not a NUL-terminated string, and
even worse, it caused undefined behavior if the length was empty;
- it returned the length of the resulting NUL-terminated string,
which was inconsistent with the input buffer length.
In addition, it was not necessarily optimal:
- it wrote '\0' twice;
- it required to know the buffer length, that is the input string
length + 1, in advance.
Remove this function, and let the client use strcspn() manually.
The function assumed that the raw output of "adb connect" was a
NUL-terminated string, but it is not the case.
It this output did not end with a space or a new line character, then
sc_str_truncate() would write '\0' over the last character. Even worse,
if the output was empty, then sc_str_truncate() would write
out-of-bounds.
Avoid the error-prone sc_str_truncate() util function.
The function assumed that the raw output of "adb get-serialno" was a
NUL-terminated string, but it is not the case.
It this output did not end with a space or a new line character, then
sc_str_truncate() would write '\0' over the last character. Even worse,
if the output was empty, then sc_str_truncate() would write

Avoid the error-prone sc_str_truncate() util function.
The function assumed that the raw output of "adb getprop" was a
NUL-terminated string, but it is not the case.
It this output did not end with a space or a new line character, then
sc_str_truncate() would write '\0' over the last character. Even worse,

Avoid the error-prone sc_str_truncate() util function.
The parser assumed that its input was a NUL-terminated string, but it
was not the case: it is just the raw output of "adb devices ip route".
In practice, it was harmless, since the output always ended with '\n'
(which was replaced by '\0' on truncation), but it was incorrect
nonetheless.
Always write a '\0' at the end of the buffer, and explicitly parse as a
NUL-terminated string. For that purpose, avoid the error-prone
sc_str_truncate() util function.
Before starting the server, the actual device serial (possibly its
ip:port if it's over TCP/IP) must be known.
A serial might be requested via -s/--serial (stored in the
sc_server_params), but the actual serial may change afterwards:
- if none is provided, then it is retrieved with "adb get-serialno";
- if --tcpip is requested, then the final serial will be the target
ip:port.
The requested serial was overwritten by the actual serial in the
sc_server_params struct, which was a bit hacky.
Instead, store a separate serial field in sc_server (and rename the one
from sc_server_params to "req_serial" to avoid confusion).
Now that providing a serial is mandatory for adb commands where it is
relevant, the whole argv array may be built statically, without
allocations at runtime.
If no serial is passed, then the command would work if there is exactly
one device connected, but will fail with multiple devices.
To avoid such cases, ensure that a serial is always provided.
On Windows, adb is provided in the release archive. Most missing adb
issues come from users setting the ADB environment variable to an
incorrect value (on all platforms).
Suggesting to install platform-tools to solve the problem will just make
things worse (there will be one more adb in yet another location).
The function was initially implemented to truncate lines, but was later
generalized to accept custom delimiters. The whole documentation has not
been updated accordingly.

This aims to fix two issues with the previous implementation:
1. the whole content of downloaded archives were extracted, while only
few files are necessary;
2. the archives were extracted in the prebuild-deps/ directory as is.
As a consequence of (2), the actual directory name relied on the root
directory of the archive. For adb, this root directory was always
"platform-tools", so when bumping the adb version, the target directory
already existed and the dependency was not upgraded (the old one had to
be removed manually).
Expose common function to download a file and check its checksum, but
let the custom script for each dependency extract only the needed files
and reorganize the content if necessary.
Add an option --otg to run scrcpy with only physical keyboard and mouse
simulation (HID over AOA), without mirroring and without requiring adb.
To avoid adding complexity into the scrcpy initialization and screen
implementation, OTG mode is implemented totally separately, with a
separate window.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
Input events helpers to convert from SDL events to scrcpy events were
implemented in input_manager. To reuse them for OTG mode, move them to
input_events.h.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
The device disconnection is detected when the video socket closes.
In order to introduce an OTG mode (HID events) without mirroring (and
without server), we must be able to detect USB device disconnection.
This feature will only be used in OTG mode.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
Acksync is used to delay HID events until some request (in practice,
device clipboard synchronization) is acknowledged by the device.
This mechanism will not be necessary for OTG mode.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
The device was automatically found by sc_usb_connect(). Instead, expose
a function to find a device from a serial, and let the caller connect to
the device found (if any).
This will allow to list all devices first, then select one device to
connect to.
