Simple GUI

Playlist

Via Playlist tool button or main menu Playout → Playlist the Playlist window pops up.

The left table lists all available tasks (Scripts, Cuelists and Timestrips). To fill the Playlist (right table) move the tasks in the left list via drag and drop to the right table. To launch a task, double click on it. Alternatively, a selected task can be launched by pressing the space bar. A shortcut key is assignable via playlist context menu as well as a comment.

If the button Stop all Tasks before playing a new one is pressed, then all running tasks are stoped before the new one launches.

To Delete a Playlist item right click on the item and select Delete Playlist item To edit the comment of an item right click on the item and select Edit Comment To assign a Hotkey to an item right click the item and select Edit Key

Make sure that the textfield has the focus and press a key.

CallButtons

CallButtons provide another way to have a GUI for end users. Since V-Control 4.1.2 they have the ability to fire on Hotkey press. Unlike in the playlist this works even if the button window does not have the focus. So it can also be minimized and another application can be in the foreground. This is a very simple and convenient solution to integrate Elgato Strem Deck.

Click Playout→CallButtons to open the CallButton window.

To add a new button click right on a free space and select the Add Button context menu. Each time the Add Button menu is clicked a new button occurs on the CallButton surface.

To assign a task to a button, right click on the button and select the context menu Select Task. This opens a window with all available tasks. Select one and click Add. By default, the task name is used as caption for the button. If you want another caption then the task name, you can click right on the button and select Change Caption

To assign a Hotkey to a button right click on it and select Change Hotkey

Make sure that the text field has the focus and press a key that should start the task assigned to that button. If you have connected an Elgato Stream Deck and have defined buttons as hotkeys there, you can now also press the corresponding buttons on the Stream Deck.

Elgato Stream Deck or other Keyboards

In V-Control you can assign tasks to Hotkeys. Hotkeys are keys pressed on a keyboard. The Keyboard can by a typical PC Keyboard, a controller that connects to a pc as keyboard or a device such as Elgato Stream Deck or Infinitton Display.

In this example I will explain how to use the Stream Deck, but it's the same procedure with any other keyboard device.

V-Control has two places to work with Hotkeys, the Playlist and the Call Button window. Both have pro's and con's. Lets start with the Playlist. If you have not used the Playlist yet or need to know how it works please read the Playlist section first.

Playlist with Hotkeys

In the Playlist we can assign keys to playlist items. We now use the Stream Deck to send keystrokes to the Playlist.

At the right bar of the Stream Deck Software we select System and the Hotkey (my version is in German, so it might look a little different then yours). Drag the Hotkey icon to a free button on the Stream Deck. At the bottom of the Stream Deck window you can configure the Button. Set a meaningful Title that explains what the task is doing and click the Hotkey field then. Now press a key on your Keyboard or select one by pressing the small triangle at the right corner of the Hotkey field.

Now open the Playlist window, right click on an item and select Edit Key. If the Key Capture window opens select the text field to make sure it has the focus. Now press the key on the Stream Deck (I mean the physical device in this case, not the software). The Key is now captured and assigned if you press OK.

Call Buttons with Hotkeys vs. Playlist

As described in the section Call Buttons, we can also assign Hotkeys to buttons. The Stream Deck part is exactly the same then we did in the Playlist example. To capture a Hotkey for a button right click the button and select Change Hotkey. Now press the key on the Stream Deck and click OK. The caption of the Button changes. It starts with the keyname and a “:”, followed by the Caption.

There is an important difference between the Playlist and the Call Buttons.

The Playlist will get the key-press events only if it has the focus. There is an Option to start the Playlist as modal dialog ( In the Main Menu select Configure→Options and check the Modal Playlist Dialog checkbox). As modal Dialog you can't access the V-Control window until the playlist is closed. Ifd the Playlist does not have the focus, the key-press event is forwarded to the element that has the focus, and the task that is assigned to the hotkey will not fire.

For the Call Button Window it is not necessary to have the focus. As soon as the window opens, a process is running that capture all key-press events, even if you type text in an editor for example. You can minimize the window and still the keyboard events will be recognized.

Depending on what you are doing the Playlist or Call Button method might be better. Keep in mind that in both cases key-press events are send to the element that has the focus. So if, for example, the Hotkey is F1, and you have an application running that has the focus, it might show it's help screen.

By the way, it is OK to use both, the Playlist and the Call buttons at the same time. But if the Playlist has the focus, and there is the same Hotkey in the Playlist and in the Call Button window, then the task might be fired twice. That depends on how long the Task is running. If the task runs very short this can happen. If it needs longer, then the second execution will not happen because a running task can not be started again.

By all this keep in mind that using the TCP_StreamDeckConnector is not so convenient, but more secure.
