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.
If we don't do this trick, the prebuilt_server will be
../server/[the_user_defined_path]. In general, we will not give an relative path
based on build directory, which leads to wrong prebuilt_server path.
The building error:
ninja: error: '../scrcpy-server-v1.7.jar', needed by
'server/scrcpy-server.jar', missing and no known rule to make it

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.
The format to use is determined by the option -F/--record-format if set,
or by the file extension (".mp4" or ".mkv").
Some containers force their own time base. For example, matroska
overwrite time_base to (AVRational) {1, 1000}.
Therefore, rescale our packet timestamps to the output stream time base.

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.
