The current process could be waited both by run_file_handler() and
file_handler_stop().
To avoid the race condition, wait the process without closing, then
close with mutex locked.
There were two versions: process_wait() and process_wait_noclose().
Expose a single version with a flag (it was already implemented that way
internally).
The function process_wait() returned a bool (true if the process
terminated successfully) and provided the exit code via an output
parameter exit_code.
But the returned value was always equivalent to exit_code == 0, so just
return the exit code instead.
The size, point and position structs were defined in common.h. Move them
to coords.h so that common.h could be used for generic code to be
included in all source files.
The header libavformat/version.h was included, but not
libavcodec/version.h.
As a consequence, the LIBAVCODEC_VERSION_INT definition depended on the
caller includes.
On Linux, waitpid() both waits for the process to terminate and reaps it
(closes its handle). On Windows, these actions are separated into
WaitForSingleObject() and CloseHandle().
Expose these actions separately, so that it is possible to send a signal
to a process while waiting for its termination without race condition.
This allows to wait for server termination normally, but kill the
process without race condition if it is not terminated after some delay.
Let the server terminate properly once all the sockets are closed.
If it does not terminate (this can happen if the device is asleep), then
kill it.
Note: since the server process termination is detected by a flag set
after waitpid() returns, there is a small chance that the process
terminates (and the PID assigned to a new process) before the flag is
set but before the kill() call. This race condition already existed
before this commit.
Fixes#1992 <https://github.com/Genymobile/scrcpy/issues/1992>
TerminateProcess() is "equivalent" to kill(), while
WaitForSingleObject() is "equivalent" to waitpid(), so the handle must
be closed after WaitForSingleObject().
On Windows, scrcpy paused on error before exiting to give the user a
chance to see the user message.
This was a hack and causes issues when using scrcpy from batch scripts.
Disable this pause from the scrcpy binary, and provide a batch wrapper
(scrcpy-console.bat) to pause on error.

Do not explicitly set the clipboard text if it already contains the

Pressing Ctrl+v on the device will typically paste the clipboard
content.
Before sending the key event, synchronize the computer clipboard to the

This allows to trigger Android shortcuts.
Fixes#555 <https://github.com/Genymobile/scrcpy/issues/555>
Pressing Alt+c generates a text event containing "c", so "c" was sent to
the device when --prefer-text was enabled.
Ignore text events when the mod state matches a shortcut modifier.
Remove the Cmd modifier on macOS, which was possible only for some
shortcuts but not all.
This paves the way to make the shortcut modifier customizable.
Touch events were HiDPI-scaled twice:
- once because the position (provided as floats between 0 and 1) were
converted in pixels using the drawable size (not the window size)
- once due to screen_convert_to_frame_coords()
One possible fix could be to compute the position in pixels from the
window size instead, but this would unnecessarily round the event
position to the nearest window coordinates (instead of drawable
coordinates).
Instead, expose two separate functions to convert to frame coordinates
from either window or drawable coordinates.

I cannot reproduce the issue with Ctrl+Shift+o on any device, so in

The field lock_video_orientation may only take values between -1 and 3
(included). But the compiler may trigger a warning on the sprintf()
call, because its type could represent values which could overflow the

Increase the buffer size to remove the warning.
Trilinear filtering can currently only be enabled for OpenGL renderers.
Do not print a warning if the renderer is not OpenGL, as it can confuses
users, while nothing is wrong.
On macOS with renderer "metal", HiDPI scaling may be incorrect on

Resetting the window size fixes the problem.
Refs #15 <https://github.com/Genymobile/scrcpy/issues/15>
Position and scale the content "manually" instead of relying on the
renderer "logical size".
This avoids possible rounding differences between the computed window
size and the content size, causing one row or column of black pixels on
the bottom or on the right.
This also avoids HiDPI scale issues, by computing the scaling manually.
This will also enable to draw items at their expected size on the screen
(unscaled).
Fixes#15 <https://github.com/Genymobile/scrcpy/issues/15>
In maximized state (but not fullscreen), it was possible to resize to
fit the device screen (with Ctrl+x or double-clicking on black borders).
This caused problems on macOS with the "expand to fullscreen" feature,
which behaves like a fullscreen mode but is seen as maximized by SDL.
In that state, resizing to fit causes unexpected results.
To keep the behavior consistent on all platforms, just disable "resize
to fit" when the window is maximized.
On Windows, in maximized+fullscreen state, disabling fullscreen mode
unexpectedly triggers the "restored" then "maximized" events, leaving
the window in a weird state (maximized according to the events, but not
maximized visually).
Moreover, apply_pending_resize() asserts that fullscreen is disabled.
To avoid the issue, if fullscreen is set, just ignore the "restored"
event.
If the content size changes (due to rotation for example) while the
window is maximized or fullscreen, the resize must be applied once
fullscreen and maximized are disabled.
The previous strategy consisted in storing the windowed size, computing
the target size on rotation, and applying it on window restoration. But
tracking the windowed size (while ignoring the non-windowed size) was
tricky, due to unspecified order of SDL events (e.g. size changes can be
notified before "maximized" events), race conditions when reading window
flags, different behaviors on different platforms...
To simplify the whole resize management, store the old content size (the
frame size, possibly rotated) when it changes while the window is
maximized or fullscreen, so that the new optimal size can be computed on
window restoration.
By default, Ctrl+C just kills the process on Windows. This caused
corrupted video files on recording.
Handle Ctrl+C properly to clean up properly.
Fixes#818 <https://github.com/Genymobile/scrcpy/issues/818>
Now that the server can access the Android settings and clean up
properly, handle the "show touches" option from the server.
The initial state is now correctly restored, even on device
disconnection.
The window dimensions are integers, so resizing to fit the content may
not be exact.
When computing the optimal size, it could cause to reduce alternatively
the width and height by few pixels, making the "optimal size" unstable.
To avoid this problem, check if the optimal size is already correct
either by keeping the width or the height.
Move the window-to-frame coordinates conversion from the input manager
to the screen.
This will allow to apply more screen-related transformations without
impacting the input manager.
Some compilers warns on uninitialized value in impossible case:
warning: variable 'result' is used uninitialized whenever switch
default is taken [-Wsometimes-uninitialized]
A double-click outside the device content (in the black borders) resizes
so that black borders are removed. But the display rotation was not
taken into account to detect the content.
Use the content size instead of the frame size to fix the issue.

The server may die before connecting to the client. In that case, the
client was blocked indefinitely (until Ctrl+C) on accept().
To avoid the problem, close the server socket once the server process is
dead.
Accept a range of ports to listen to, so that it does not fail if
another instance of scrcpy is currently starting.
The range can be passed via the command line:
scrcpy -p 27183:27186

The default is 27183:27199.

Start the server socket in enable_tunnel() directly.
For the caller point of view, enabling the tunnel opens a port (either

Mouse events coordinates depend on the screen size and location, so the
converter need to access the screen.
The fact that it needs the position or the size is an internal detail,
so pass a pointer to the whole screen structure.
Now, get_window_size() returns the current window size (fullscreen or
not), while get_windowed_window_size() always returned the windowed size
(the size when fullscreen is disabled).
Headers seem to be a bit different in Apple land and you need to include
stddef.h explicitly to the NULL declaration.
This also makes the code a bit more correct, as stddef.h is the header
in the C standard that defines NULL
(https://en.cppreference.com/w/cpp/header/cstddef).
We need several FIFO queues (a queue of packets, a queue of messages,
etc.).
Some of them are implemented using cbuf, a generic circular buffer. But
for recording, we need to store the packets in an unbounded queue until
they are written, so the queue was implemented manually.
Create a generic implementation (using macros) to avoid reimplementing
it every time.
The record file was written from the stream thread. As a consequence,
any blocking I/O to write the file delayed the decoder.
For maximum performance even when recording is enabled, send
(refcounted) packets to a separate recording thread.
To packetize the H.264 raw stream, av_parser_parse2() (called by
av_read_frame()) knows that it has received a full frame only after it
has received some data for the next frame. As a consequence, the client
always waited until the next frame before sending the current frame to
the decoder!
On the device side, we know packets boundaries. To reduce latency,
make the device always transmit the "frame meta" to packetize the stream
manually (it was already implemented to send PTS, but only enabled on
recording).
On the client side, replace av_read_frame() by manual packetizing and
parsing.

If --no-control is set, then the controller is not initialized (both in

In portable builds, scrcpy-server.jar was supposed to be present in the

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

On socket disconnection, on Linux, recv() returns -1 and errno is set.

Only keep "turn device screen off" and POWER button.

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

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.)
The decoder initially read from the socket, decoded the video and sent
the decoded frames to the screen:
+---------+ +----------+
socket ---> | decoder | ---> | screen |
+---------+ +----------+
The design was simple, but the decoder had several responsabilities.
Then we added the recording feature, so we added a recorder, which
reused the packets received from the socket managed by the decoder:
+----------+
---> | screen |
+---------+ / +----------+
socket ---> | decoder | ----
+---------+ \ +----------+
---> | recorder |
+----------+
This lack of separation of concerns now have concrete implications: we
could not (properly) disable the decoder/display to only record the
video.
Therefore, split the decoder to extract the stream:
+----------+ +----------+
---> | decoder | ---> | screen |
+---------+ / +----------+ +----------+
socket ---> | stream | ----
+---------+ \ +----------+
---> | recorder |
+----------+
This will allow to record the stream without decoding the video.
The order of cleanup was not the reverse as the initialization order. As
a consequence, recorder_destroy() could theoretically be called even if
recorder_init() failed.
The deprecated avcodec_decode_video2() should always the whole packet,
so there is no need to loop (cf doc/examples/demuxing_decoding.c in
FFmpeg).
This hack changed the packet size and data pointer. This broke recording
which used the same packet.
The extradata buffer is owned by libav, so it must be allocated with
av_malloc(), not SDL_malloc().
This fixes a crash on Windows during avformat_free_context().
Windows does not support UTF-8, so pushing a file with non-ASCII
characters failed.
Convert the UTF-8 command line to a wide characters string and call
CreateProcessW().

Implement recording to Matroska files.

overwrite time_base to (AVRational) {1, 1000}.

To clean up the device, the client executed "adb shell rm" once the
server was guaranteed to be started (after the connection succeeded).
This implied to track whether the installation state, and failed if an
additional tunnel was used in "forward" mode:
<https://github.com/Genymobile/scrcpy/issues/386#issuecomment-453936034>
Instead, make the server unlink itself on start.
Mouse events position were unsigned (so negative values could not be
handled properly).
To avoid issues with negative values, mouse events outside the device
screen were ignored (commit a7fe9ad779).
But as a consequence, drag&drop were "broken" if the "drop" occurred
outside the device screen.
Instead, use signed 32-bits to store the position, and forward events
outside the device screen.
Fixes <https://github.com/Genymobile/scrcpy/issues/357>.
Never create a "struct point" with a position possibly outside the
device screen (i.e. in the black borders area), and do not transmit such
events.
This fixes an assertion failure on mouse wheel events outside the device
screen area.
The client passes parameters to the server via "adb shell" arguments.
Use "-" instead of "" when no crop is specified to avoid empty
arguments, which are not handled the same way on all devices.

Configuration packets produced by MediaCodec have no valid PTS, and do
not produce frame. Do not queue their (invalid) PTS not to break the
matching between frames and their PTS.
Several frames may be read by read_packet() before they are consumed
(returned by av_read_frame()), so we need to store the PTS of frames in
order, so that the right PTS is assigned to the right frame.
AVStream.codec has been deprecated in favor of AVStream.codecpar.
Due to the FFmpeg/Libav split, this happened in two separate versions:
- 57.33.100 for FFmpeg
- 57.5.0 for Libav
This partially reverts commit f00c6c5b13.
On Ctrl+C, we need to execute cleanup code. For instance, if recording
is enabled, we need to write MP4 file trailer on exit.
Custom SDL signal handlers were disabled because it leaded to process
hanging on Ctrl+C during network calls on initialization, but now it
seems to work correctly, the network calls return immediately on signal.
Since PTS handling has been fixed, the recorder do not associate a PTS
to a wrong frame anymore, so PTS of "configuration packets" (which never
produce a frame), are never read by the recorder. Therefore, there is no
need to ignore them explicitly, so we can remove the MediaCodec flags
completely.
The PTS was read from the socket and set as the current one even before
the frame was consumed, so it could be assigned to the previous frame
"in advance".
Store the PTS for the current frame and the last PTS read from the
packet header of the next frame in separate fields.
As a side-effect, this fixes the warning on quit:

The call to installer_stop() then called kill(0, SIGTERM) (on Linux),
which sent SIGTERM to every process in the process group. In particular,
the scrcpy process was killed.
As a consequence, the last cleanup steps, like disabling "show touches",
were not executed.
Fixes <https://github.com/Genymobile/scrcpy/issues/183>.
In practice, proc_show_touches may not be used uninitialized, since it
checks the flag options->show_touches, but the compiler can't know that,
so initialize it to avoid the warning.
