On H.264 stream EOF, the eof_reached flag is set, but av_read_frame()
still provides a frame, so check the flag only afterwards.
As a side-effect, it also fixes a memory leak (the very last packet was
not unref).
Since _scrcpy_ also supports `adb forward`, remove the part about `adb
reverse`.
Make explicit that _adb_ is included in the prebuilt application for
Windows (many users manually download the platform-tools for no reason).
Request SDL not to replace the SIGINT and SIGTERM handlers, so that the
process is immediately terminated on Ctrl+C.
This avoids process hanging on Ctrl+C during network calls on
initialization.
Some of them accepted a timeout, but it was not used since
commit 9b056f5091 anymore.
In "adb forward" mode, close the server socket as soon as the client is
connected.
Even if unlikely to be useful, it allows to run several instances of
scrcpy also in "adb forward" mode.
On Windows and MacOS, resizing blocks the event loop, so resizing events
are not triggered:
- <https://bugzilla.libsdl.org/show_bug.cgi?id=2077>
- <https://stackoverflow.com/a/40693139/1987178>
As a workaround, register an event watcher to render the screen from
another thread.
Since the whole event loop is blocked during resizing, the screen
content is not refreshed (on Windows and MacOS) until resizing ends.
"adb reverse" currently does not work over tcpip (i.e. on a device
connected by "adb connect"):
<https://issuetracker.google.com/issues/37066218>
To work around the problem, if the call to "adb reverse" fails, then
fallback to "adb forward", and reverse the client/server roles.
Keep the "adb reverse" mode as the default because it does not involve
connection retries: when using "adb forward", the client must try to
connect successively until the server listens.
Due to the tunnel, every connect() will succeed, so the client must
attempt to read() to detect a connection failure. For this purpose, when
using the "adb forward" mode, the server initially writes a dummy byte,
read by the client.
Fixes <https://github.com/Genymobile/scrcpy/issues/5>.
The serial is needed for many server actions, but this is an
implementation detail, so the caller should not have to provide it on
every call.
Instead, store the serial in the server instance on server_start().
This paves the way to implement the "adb forward" fallback properly.
The SDL mouse wheel event seems inconsistent between horizontal and
vertical scrolling.
> Movements to the left generate negative x values and to the right
> generate positive x values. Movements down (scroll backward) generate
> negative y values and up (scroll forward) generate positive y values.

Reverse the horizontal.
Fixes <https://github.com/Genymobile/scrcpy/issues/49>.
Document server and client dependencies separately, to avoid unneeded
packages installation when building using the prebuilt server.
Also remove "zip", since it's only used for building a portable version
(which is not documented in README).
