Only keep "turn device screen off" and POWER button.
After we turn the device screen off (with Ctrl+o), turning it back on
does not always work, and leaves the device in a weird state, where even
the power button may not be sufficient:
<https://github.com/Genymobile/scrcpy/issues/175#issuecomment-497946596>
This is not an acceptable behavior, so disable the shortcut to turn the
physical device screen on. We can use the POWER button (or Ctrl+p)
instead.
Add two shortcuts:
- Ctrl+o to turn the device screen off while mirroring
- Ctrl+Shift+o to turn it back on
On power on (either via the POWER key or BACK while screen is off), both
the device screen and the mirror are turned on.

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.

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.

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.)
Implement recording to Matroska files.
The format to use is determined by the option -F/--record-format if set,
or by the file extension (".mp4" or ".mkv").
It is very convenient when I play mobile game and watch video at the
same time.
Tested on Linux mint Cinnamon as well as Windows 10.

I could not make Ctrl+'+' and Ctrl+'-' work for every keyboard on every
platform.
Instead, use Ctrl+UP and Ctrl+DOWN (like in VLC) to change the volume.
Fixes <https://github.com/Genymobile/scrcpy/issues/103>.
Paste computer clipboard to the device on Ctrl+v.
The other direction (pasting the device clipboard to the computer) is
not implemented. It would require a communication channel from the
device to the computer, other than the socket used by the video stream.
SDL_net is not very suitable for scrcpy.
For example, SDLNet_TCP_Accept() is non-blocking, so we have to wrap it
by calling many SDL_Net-specific functions to make it blocking.
But above all, SDLNet_TCP_Open() is a server socket only when no IP is
provided; otherwise, it's a client socket. Therefore, it is not possible
to create a server socket bound to localhost, so it accepts connections
from anywhere.
This is a problem for scrcpy, because on start, the application listens
for nearly 1 second until it accepts the first connection, supposedly
from the device. If someone on the local network manages to connect to
the server socket first, then they can stream arbitrary H.264 video.
This may be troublesome, for example during a public presentation ;-)
Provide our own simplified API (net.h) instead, implemented for the
different platforms.
The device serial was provided as a positional argument:
scrcpy 0123456789abcdef
Instead, expose it as an optional argument, -s or --serial:
scrcpy -s 0123456789abcdef
This avoids inconsistency between platforms when the positional
argument is passed before the options (which is undefined).
For readability, indent "case" in switch blocks.
Replace:
switch (x) {
case 1:
// ...
case 2:
// ...
case 3: { // a local scope block
int i = 42;
// ...
}
}
By:
switch (x) {
case 1:
// ...
case 2:
// ...
case 3: { // a local scope block
int i = 42;
// ...
}
}
Accept a parameter to limit the video size.
For instance, with "-m 960", the great side of the video will be scaled
down to 960 (if necessary), while the other side will be scaled down so
that the aspect ratio is preserved. Both dimensions must be a multiple
of 8, so black bands might be added, and the mouse positions must be
computed accordingly.
