The keyboard settings can be opened by:
adb shell am start -a android.settings.HARD_KEYBOARD_SETTINGS
Add a shortcut (MOD+k) for convenience if the current keyboard is HID.
PR #4473 <https://github.com/Genymobile/scrcpy/pull/4473>
The audio output thread only reads samples from the buffer, and most of
the time, the audio receiver thread only writes samples to the buffer.
In these cases, using atomics avoids lock contention.
There are still corner cases where the audio receiver thread needs to
"read" samples (and drop them), so lock only in these cases.
PR #4572 <https://github.com/Genymobile/scrcpy/pull/4572>
If a line did not end with '\r', then the final `\n' was replaced by
'\0' for parsing the current line. This `\0` was then mistakenly
considered as the end of the whole "ip route" output, so the remaining
lines were not parsed, causing "scrcpy --tcpip" to fail in some cases.
To fix the issue, read the final character of the current line before it
is (possibly) overwritten by '\0'.
The slope encodes the drift between the device clock and the computer
clock. Its real value is expected very close to 1.
To estimate it, just assume it is exactly 1.
Since the clock is used to estimate very close points in the future, the
error caused by clock drift is totally negligible, and in practice it is
way lower than the slope estimation error.
Therefore, only estimate the offset.
If there is exactly one producer, then it can assume that the remaining
space in the buffer will only increase until it writes something.
This assumption may allow the producer to write to the buffer (up to a
known safe size) without any synchronization mechanism, thus allowing
to read and write different parts of the buffer in parallel.
The producer can then commit the write with a lock held, and update its
knowledge of the safe empty remaining space.
PR #3757 <https://github.com/Genymobile/scrcpy/pull/3757>
On click event, only the whole buttons state was passed to the device.
In addition, on ACTION_DOWN and ACTION_UP, pass the button associated to
the action.

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 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.
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.
There was only two key injection modes:
- the default one
- the mode with --prefer-text enabled
To prepare the addition of another mode (--raw-key-events), use an enum
instead of a bool.

Depending on the platform and adb versions, the lines output by adb
could end with "\r\r\n". This util function helps to remove all trailing
'\r'.
