Video

) form object makes it possible to add a video inside of a form. The Video form object embeds a video file in a form. The video is a web page created in HTML5. The supported video file formats are .mp4 (MP4 format), .ogv (OGV format), and .webm (WebM format) files. However, not all video file formats are supported on all platforms. When running an application by connecting to COMSOL Server from a web browser, which formats are supported depend on the web browser and may vary with different versions of the same web browser. Of these formats, MP4 works with most web browsers, whereas OGV and WebM work in Firefox and Google Chrome (as web clients).

Specify a name for the image in the field. The name must be unique among the form objects in the form. Specify a video file to use from the list, or click the button (

) to locate a video file to use on the file system. That video then becomes a part of the library and selected as the video in the object. To not show a video, select from the list. Click the button (

) to export the video file to the file system (for use in another application, for example).

	The file reference points to a file resource on the local system that may not be present when running the application. When saving, all file references are embedded into the MPH-file, so you do not have to distribute them along with the application. A running application always looks for embedded resources first.

In the Form Editor, a placeholder image appears where the video will appear when running the application.

The check box is selected by default. The user of the application can then control the video using controls to pause and play the video and to mute and unmute the sound. Clear this check box to show the video without any controls.

Select the check box if you want the video to start directly when the user runs the application.

Select the check box if you want the video to keep running repeatedly.

Select the check box if you want the video to be initially muted (no sound).

	To show a video when running an application with COMSOL Multiphysics and with the COMSOL Client, the Internet Explorer version installed on your computer is used as a software component for displaying the video object.

In addition, the window contains the following sections.

This section contains all layout settings for a video in the grid of the parent form.

In the grid mode, you can control the horizontal and vertical alignment of the video using the following lists:

•

From the list, choose , , , or , which automatically expands the form object to fill the cell in the horizontal or vertical direction (where applicable).

•

From the list, choose , , , or , which automatically expands the form object to fill the cell in the horizontal or vertical direction (where applicable).

The need to specify the alignment is most obvious when working in the grid mode, as it controls how the form object is aligned in its grid cell. Aligning the form object can be useful in the sketch mode too, and you can then use the alignment tools on the menu in the toolbar’s section. When running the application in any client other than the Windows client, the form objects may not be positioned exactly as seen in the form windows. This is because the form objects may have a different size in other clients, giving them a slightly different positioning. Specifying the alignment ensures that the form objects are aligned as you want them to be in all clients.

The and fields are unavailable because the dimensions of the image are determined by the software.

Additionally, in the sketch mode, you can specify the absolute position of the video using the and fields. In the grid mode, you can position the object in the grid and see the grid position as the , , , and values.

	The form windows update these size and positioning settings through the draw operations performed there, such as resizing and moving the object.

Under (in grid mode only), you can control the margins around the form object. By default, the margins are taken from the parent form. From the list, choose:

Under , you can control the initial state of the video when users run the application. By default, the image is visible. Clear the check box if you want to make the initial state of the video hidden. You can then make it visible using a method. Objects that are hidden become visible when selected in the Form Editor.
