Romain Vimont 5b9c88693e Wait using a condition variable in server 
Currently, server_stop() is called from the same thread as
server_connect_to(), so interruption may never happen.

This is a step to prepare executing the server from a dedicated thread.

Romain Vimont ac23bec144 Expose socket interruption 
On Linux, socket functions are unblocked by shutdown(), but on Windows
they are unblocked by closesocket().

Expose net_interrupt() and net_close() to abstract these differences:
 - net_interrupt() calls shutdown() on Linux and closesocket() on
   Windows (if not already called);
 - net_close() calls close() on Linux and closesocket() on Windows (if
   not already called).

This simplifies the server code, and prevents a data race on close
(reported by TSAN) on Linux (but does not fix it on Windows):

Romain Vimont 5222f213f4 Update FAQ to mention HID keyboard 2021-10-26 21:30:04 +02:00
Romain Vimont e4163321f0 Delay HID events on Ctrl+v 
When Ctrl+v is pressed, a control is sent to the device to set the
device clipboard before injecting Ctrl+v.

With the InputManager method, it is guaranteed that the device
synchronization is executed before handling Ctrl+v, since the commands
are executed on the device in sequence.

However, HID are injected from the computer, so there is no such
guarantee. As a consequence, on Android, Ctrl+v triggers a paste with
the old clipboard content.

To workaround the issue, wait a bit (2 milliseconds) from the AOA
thread before injecting the event, to leave enough time for the
clipboard to be set before injecting Ctrl+v.

Romain Vimont c96874b257 Synchronize HID keyboard state on first event

Romain Vimont 79278961b9 Implement buffering 
To minimize latency (at the cost of jitter), scrcpy always displays a
frame as soon as it available, without waiting.

However, when recording (--record), it still writes the captured
timestamps to the output file, so that the recorded file can be played
correctly without jitter.

Some real-time use cases might benefit from adding a small latency to
compensate for jitter too. For example, few tens of seconds of latency
for live-streaming are not important, but jitter is noticeable.

Therefore, implement a buffering mechanism (disabled by default) to add
a configurable latency delay.

Romain Vimont 408a301201 Notify new frames via callbacks 
Currently, a frame is available to the consumer as soon as it is pushed
by the producer (which can detect if the previous frame is skipped).

Notify the new frames (and frame skipped) via callbacks instead.

This paves the way to add (optional) buffering, which will introduce a
delay between the time when the frame is produced and the time it is
available to be consumed.

via callbacks without lock inversion issues.
