Video Capture Device

The VLC App is no longer supported.

 

Video capture devices can be connected with the OnSign TV Windows Player. VLC is one of the most popular media Players, offering both a graphical interface and a full command line for playback. 

Requirements:

  • OnSign TV Windows Player version 10 or higher, but lower than 10.6.x. If your player is already on a higher version, request an installation link from support@onsign.tv.
  • A VLC compatible video device.
  • While installing VLC itself is not mandatory, it is nice to have for testing the capture device under VLC.
  • Having successfully installed your video device card using the device manufacturer software and drivers.
 

Although installing VLC itself on the Player is not necessary, we recommend it to test the correct operation of the capture device and to facilitate getting the configuration parameters. 

Make sure that your device is compatible and working with VLC 3.0 to be used as:

  • Capture for HDMI
  • WebCam or Camera
  • TV tuner card

Configuration:

  1. Ensure that all necessary drivers for your capture card are correctly installed.
  2. To check if the drivers are correct, the capture device must work correctly when using the software provided by the device manufacturer.
  3. Download and install VLC.
  4. With the capture device installed and connected, open VLC and select Media > Open Capture Device.
  5. As Capture mode select "DirectShow" for video capture cards and WebCams or TV - digital for TV tuner cards.

  2. Copy the parameters shown in Edit Options into the Playback Arguments of the OnSign TV VLC App.

    IMPORTANT

    Remove the colon symbol ":" before each parameter.

    Use quotes to define parameters that contain spaces as characters:

    Example: 
    Parameters in VLC :dshow-vdev=HD Webcam C525 live-caching=300 
    Change parameters to dshow-vdev= "HD Webcam C525" live-caching=300

Command examples:

Built-in webcam

This will usually be the default DirectShow device.

HDMI-in

Once you correctly see the HDMI-in capture in VLC, configure the OnSign TV VLC App with the same parameters used in your previous test.

TV Tuner

Use the tuner card's manufacturer's software to find the frequency of each channel.

The channel width depends on the location and the specific Digital TV Standard used. In this example, we set the channel width to 6 MHz (or 6000 Hz).
