All server logs were printed to stdout, while all client logs were
printed to stderr.
Instead, use stderr for warnings and errors, stdout for the others:
- stdout: verbose, debug, info
- stderr: warn, error
Play the decoded audio using SDL.
The audio player frame sink receives the audio frames, resample them
and write them to a byte buffer (introduced by this commit).
On SDL audio callback (from an internal SDL thread), copy samples from
this byte buffer to the SDL audio buffer.
The byte buffer is protected by the SDL_AudioDeviceLock(), but it has
been designed so that the producer and the consumer may write and read
in parallel, provided that they don't access the same slices of the
ring-buffer buffer.
PR #3757 <https://github.com/Genymobile/scrcpy/pull/3757>
Co-authored-by: Simon Chan <1330321+yume-chan@users.noreply.github.com>
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>
If the current adb port is not 5555 (typically 0 because it is not in
TCP/IP mode), --tcpip automatically executes (among other commands):
adb tcpip 5555
In case adb was already listening on another port, this command forced
to listen on 5555, and the connection should still succeed.
But this reconfiguration might be inconvenient for the user. If adb is
already in TCP/IP mode, use the current enabled port without
reconfiguration.
Fixes#3591 <https://github.com/Genymobile/scrcpy/issues/3591>
All adb commands are executed with an "interruptor", so that they can be
interrupted on Ctrl+C.
Make this interruptor optional, so that we could call "adb kill-server"
in OTG mode. This command always returns almost immediately anyway.
Ideally, we should make all blocking calls interruptible (including
libusb calls, by using the asynchronous API), but it's a lot of work,
and in practice it works well enough.
PR #3011 <https://github.com/Genymobile/scrcpy/pull/3011>
The value of sc_tick_now() has microsecond precision, but
sc_cond_timedwait() has only millisecond precision.
To guarantee that sc_tick_now() >= deadline when sc_cond_timedwait()
returns due to timeout, round up to the next millisecond.
This avoids to call a non-blocking sc_cond_timedwait() in a loop for no
reason until a target deadline during up to 1 millisecond.

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.
PR #3005 <https://github.com/Genymobile/scrcpy/pull/3005>
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 was initially implemented to truncate lines, but was later
generalized to accept custom delimiters. The whole documentation has not
been updated accordingly.

Prefix the name of threads by "scrcpy-". This improves readability in
the output of `top -H` for example.
Limit the thread names to 16 bytes, because it is limited on some
platforms.
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'.
PR #2827 <https://github.com/Genymobile/scrcpy/pull/2827>
Let the caller decide if stdout and stderr must be inherited on process
creation, i.e. if stdout and stderr of the child process should be
printed in the scrcpy console.
This allows to get output and errors for specific adb commands depending
on the context.
PR #2827 <https://github.com/Genymobile/scrcpy/pull/2827>
If SOCK_CLOEXEC exists, then set the flag on socket creation.
Otherwise, use fcntl() (or SetHandleInformation() on Windows) to set the
flag afterwards.
This avoids the sockets to be inherited in child processes.
