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.
Currently, we only use screen information (width, height, rotation)
once at initialization, to send the device size to the client.
To be able to scale mouse events, make it accessible in memory. For this
purpose, replace the "static" DeviceUtil to a singleton Device, and
update it on every screen rotation.
To control the device from the computer:
- retrieve mouse and keyboard SDL events;
- convert them to Android events;
- serialize them;
- send them on the same socket used by the video stream (but in the
opposite direction);
- deserialize the events on the Android side;
- inject them using the InputManager.
Move the DeviceUtil internal static classes to public classes, in a
separate package (".wrappers").
This paves the way to implement InputManager properly.
