Romain Vimont 9253996873 Add README section explaining --turn-screen-off 2019-06-05 19:02:42 +02:00
Romain Vimont 8e66b33000 Add option to turn device screen off 
In addition to the shortcut (Ctrl+o) to turn the device screen off, add
a command-line argument to turn it off on start.
 2019-06-05 00:55:46 +02:00
Romain Vimont 7f07b13446 Indent command-line options 
Preparse indentation for --turn-screen-off.
 2019-06-05 00:55:39 +02:00
Romain Vimont acc4dcd520 Disable server controller if --no-control 
If --no-control is disabled, there is no need for a controller.

It also avoids to power on the device on start if control is disabled.
 2019-06-05 00:25:57 +02:00
Romain Vimont ca767ba364 Group server params in a struct 
Starting the server requires more and more parameters. For clarity,
group them in a struct.
 2019-06-05 00:25:57 +02:00
Romain Vimont c8a6783494 Use positive options names internally 
For clarity, store the flag resulting of the command-line options
--no-control and --no-display into "control" and "display".
 2019-06-05 00:25:15 +02:00
Romain Vimont 5b56900e2b Rename unused field 
The flag is used only in the server_start() implementation, there is no
need to store it in the structure.
 2019-06-04 21:29:14 +02:00
Romain Vimont 8c8649cfcd Remove "turn device screen on" feature 
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.
 2019-06-03 11:44:39 +02:00
Romain Vimont e572d81fa2 Rename function to "power on" 
This will reduce confusion between "power on" when the device is off and
"turn device screen off" while mirroring.
 2019-06-02 20:34:52 +02:00
Romain Vimont 41225c3e41 Improve key processing readability 
The condition "event->type == SDL_KEYDOWN" and the variable
input_manager->controller are used many times. Replace them by local
variables to reduce verbosity.
 2019-06-01 07:18:05 +02:00
Romain Vimont 296047d82a Use net_close() to close sockets 
So that it also works on Windows.
 2019-05-31 23:33:44 +02:00
Romain Vimont 0792998cc2 Remove unused import 
Introduced by the previous commit.
 2019-05-31 23:31:53 +02:00
Romain Vimont 12a3bb25d3 Implement device screen off while mirroring 
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.

Romain Vimont 6537c2ef01 Add clipboard logs 
Synchronizing local and device clipboards in invisible. Add INFO logs
on success.
 2019-05-31 16:18:00 +02:00
Romain Vimont 9712cb8123 Do not minimize on focus loss 
The default behavior seems annoying.

 2019-05-31 16:18:00 +02:00
Romain Vimont ad55a9addc Prefix server logs 
Sometimes, it is not obvious whether a log is generated by the server or
by the client. Prefix server logs for clarity.
 2019-05-31 16:18:00 +02:00
Romain Vimont 28980bbc90 Rename "event" to "message" 
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.
 2019-05-31 16:18:00 +02:00
Romain Vimont f710d76c9e Merge pull request #568 from npes87184/dev 
Correct return value type in handle_event
 2019-05-31 15:27:35 +02:00
Romain Vimont 0125af1e46 Update DEVELOP after recent refactorings 2019-05-30 22:46:52 +02:00
Romain Vimont c13a24389c Implement computer-to-device clipboard copy 
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.

Romain Vimont 2322069656 Extract control event String parsing 
Parsing a String from a serialized control event, encoded as length (2
bytes) + data, will be necessary in several events.

Extract it to a separate method.
 2019-05-30 22:46:52 +02:00
Romain Vimont 61f5f96b42 Fix control event String parsing 
At least 2 bytes must be available to read the length of the String.
 2019-05-30 22:46:52 +02:00
Romain Vimont 63c078ee6c Implement device-to-computer clipboard copy 
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>
 2019-05-30 22:46:52 +02:00
Romain Vimont 3149e2cf4a Add device event sender 
Create a separate component to send device events, managed by the
controller.
 2019-05-30 22:46:52 +02:00
Romain Vimont 6112095e75 Add device event receiver 
Create a separate component to handle device events, managed by the

 2019-05-30 22:46:52 +02:00
Romain Vimont f9d2d99166 Add GET_CLIPBOARD device event 
Add the first device event, used to forward the device clipboard to the
computer.
 2019-05-30 22:36:22 +02:00
Romain Vimont ec71a3f66a Use two sockets for video and control 
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.
 2019-05-30 22:35:41 +02:00
Romain Vimont 69360c7407 Extract control event string serialization 
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.
 2019-05-30 22:35:04 +02:00
Romain Vimont 6ec2ddd2d1 Truncate UTF-8 properly 
This will avoid to produce invalid UTF-8 results (although unlikely).
 2019-05-30 22:34:59 +02:00
Romain Vimont 0a7fe7ad57 Add helpers to truncate UTF-8 at code points 
This will help to avoid truncating a UTF-8 string in the middle of a
code point, producing an invalid UTF-8 result.
 2019-05-30 22:30:18 +02:00
Romain Vimont 3aa5426cad Add unit tests for control events serialization 
Add missing tests for serialization and deserialization of control
events.

Romain Vimont ad4c061cd2 Use custom class Point 
The framework class android.graphics.Point cannot be used in unit tests.
Implement our own Point.
 2019-05-30 22:30:18 +02:00
Romain Vimont 63909fd10d Merge commands with other control 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.
 2019-05-30 22:30:18 +02:00
Romain Vimont 3b4366e5bf Stop stream immediately on quit 
If the stream is stopped, av_read_frame() will be woken up and yield a
corrupted packet. Do not try to decode or record it.
 2019-05-30 22:30:18 +02:00
Romain Vimont 47f1003200 Close server socket before killing process 
The sockets may be closed and shutdown on server_stop(). This will
interrupt the stream and controller threads more quickly and gracefully.
 2019-05-30 22:30:18 +02:00
Romain Vimont bfb86ca2c2 Simplify cleanup 
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.
 2019-05-30 22:30:18 +02:00
Romain Vimont 0dee9b04b2 Use net_recv() to read only one byte 
Partial read is impossible for 1 byte, so net_recv_all() is useless.
 2019-05-30 22:30:18 +02:00
Romain Vimont 8fc58bde75 Simplify server_connect_to() 
Only use 2 branches, using either forward or remote tunnel.
 2019-05-30 22:30:18 +02:00
Romain Vimont 5a431cdf9b Make server_connect_to() return a bool 
The resulting socket is accessible from the server instance, there is no
need to return it.

This paves the way to use several sockets in parallel.

Romain Vimont 8595862005 Use explicit output parameter for skipped frame 
The function video_buffer_offer_decoded_frame() returned a bool to

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).
