import the recent additions for video console into trunk,
giving you support for up to 9 video sources (e.g. webcams, or X11 grabbers, etc.) active at once, displaying thumbnails for each of them in the main GUI window, and with the ability to switch between them on the fly during a conversation. The code also implements a 'Picture in Picture' feature, allowing you to select any source as primary or secondary, and move the PiP window by just dragging it with the mouse. The window looks like this: ________________________________________________________________ | ______ ______ ______ ______ ______ ______ ______ | | | tn.1 | | tn.2 | | tn.3 | | tn.4 | | tn.5 | | tn.6 | | tn.7 | | | |______| |______| |______| |______| |______| |______| |______| | | ______ ______ ______ ______ ______ ______ ______ | | |______| |______| |______| |______| |______| |______| |______| | | _________________ __________________ _________________ | | | | | | | | | | | | | | | | | | | | | | | | | | | remote video | | | | local video | | | | | | | | ______ | | | | | | keypad | | | PIP || | | | | | | | |______|| | | |_________________| | | |_________________| | | | | | | | | | | |__________________| | |________________________________________________________________| git-svn-id: http://svn.digium.com/svn/asterisk/trunk@126480 f38db490-d61c-443f-a65b-d21fe96a405b

* GUI layout, structure and management
|
||||
|
||||
For the GUI we use SDL to create a large surface (gui->screen)
|
||||
containing tree sections: remote video on the left, local video
|
||||
on the right, and the keypad with all controls and text windows
|
||||
in the center.
|
||||
The central section is built using an image for the skin, fonts and
|
||||
other GUI elements. Comments embedded in the image to indicate to
|
||||
what function each area is mapped to.
|
||||
For the GUI we use SDL to create a large surface (gui->screen) with 4 areas:
|
||||
remote video on the left, local video on the right, keypad with all controls
|
||||
and text windows in the center, and source device thumbnails on the top.
|
||||
The top row is not displayed if no devices are specified in the config file.

The central section is built using an image (jpg, png, maybe gif too)
|
||||
for the skin, and other GUI elements. Comments embedded in the image
|
||||
indicate to what function each area is mapped to.
|
||||
Another image (png with transparency) is used for the font.
|
||||
|
||||
Mouse and keyboard events are detected on the whole surface, and
|
||||
handled differently according to their location:
|
||||
|
||||
- center/right click on the local/remote window are used to resize
|
||||
the corresponding window;
|
||||
- clicks on the thumbnail start/stop sources and select them as
|
||||
primary or secondary video sources;
|
||||
- drag on the local video window are used to move the captured
|
||||
area (in the case of X11 grabber) or the picture-in-picture
|
||||
location (in case of camera included on the X11 grab).
|
||||
- click on the keypad are mapped to the corresponding key;
|
||||
area (in the case of X11 grabber) or the picture-in-picture position;
|
||||
- keystrokes on the keypad are mapped to the corresponding key;
|
||||
keystrokes are used as keypad functions, or as text input
|
||||
if we are in text-input mode.
|
||||
- drag on some keypad areas (sliders etc.) are mapped to the
|
||||
corresponding functions;
|
||||
- keystrokes are used as keypad functions, or as text input
|
||||
if we are in text-input mode.
|
||||
|
||||
Configuration options control the appeareance of the gui:
|
||||
|
||||
keypad = /tmp/phone.jpg ; the skin
|
||||
keypad_font = /tmp/font.ttf ; the font to use for output (XXX deprecated)
|
||||
keypad = /tmp/kpad2.jpg ; the skin
|
||||
keypad_font = /tmp/font.png ; the font to use for output
|
||||
|
||||
For future implementation, intresting features can be the following:
|
||||
- freeze of the video coming from our remote party
|
||||
- save of the whole SDL window as a picture
|
||||
- oudio output device switching
|
||||
|
||||
The audio switching feature should allow changing the device
|
||||
or switching to a recorded message for audio sent to remote party.
|
||||
The selection of the device should happen clicking on a marker in the layout.
|
||||
For this reason above the thumbnails row in the layout we would like a new row,
|
||||
the elements composing the row could be message boards, reporting the name of the
|
||||
device or the path of the message to be played.
|
||||
|
||||
For video input freeze and entire window capture, we define 2 new key types,
|
||||
those should be activated pressing the buttons on the keypad, associated with
|
||||
new regions inside the keypad pictureas comments
