Best Practices for Video Capture Content
Broadsign has found that most consumer-grade devices and drivers do not provide a consistent and robust enough interface to support long-term. Therefore, customers can achieve a better result by utilizing the standalone version of the VLC player with specific parameters to interface with the capture device."
Operating system support will be dependent on what is supported by the capture device and its drivers. Typically, this is Windows 7 and above only. This guide is for Windows, although the VLC standalone player itself is supported on both Windows and Linux
- Access the following link:
- Ensure that the zip file downloads correctly. Save this file in an easy to remember location.
- Unpack the zip file.
- Run the
vlc.exefile located in the vlc-3.0.11 folder.
- Once installed, go to File > Open Capture Device.
- In the Device Selection section, use the Video device name and Audio device name drop-down lists to select the video capture device installed on your PC.
- Take note of the exact naming convention of the audio and video device names.
- Click Cancel.
- Close VLC.
Note: This link is an example only, use the latest VLC version available on the VLC download page.
Note: The names must be exactly as written in VLC. Ensure that when taking note, they are letter for letter, space for space an exact replica of what VLC indicates in the UI.

Example of running VLC in a custom resolution or placement on screen:
--intf dummy --no-osd --no-video-deco --no-embedded-video --autoscale --width=1920 --height=1080 --video-x=920 --video-y=50 dshow://:dshow-vdev="2D31-INOGENI 4KUSB3" :dshow-adev="2D31-INOGENI 4KUSB3" :dshow-size=1920x1080 :dshow-aspect-ratio=16\:9 :dshow-chroma= :dshow-fps=0 :no-dshow-config :no-dshow-tuner :dshow-tuner-channel=0 :dshow-tuner-frequency=0 :dshow-tuner-country=0 :dshow-tuner-standard=0 :dshow-tuner-input=0 :dshow-video-input=0 :dshow-video-output=0 :dshow-audio-input=0 :dshow-audio-output=0 :dshow-amtuner-mode=-1 :dshow-audio-channels=0 :dshow-audio-samplerate=0 :dshow-audio-bitspersample=0 :live-caching=300
This table describes the functions that you need to define in the command:
|:dshow-vdev="YOUR VIDEO DEVICE NAME HERE"||Specify your video device name, exactly as named in VLC. Use the name that you have noted in Step 7 of Installing VLC Standalone. Keep the quotation marks.|
:dshow-adev="YOUR AUDIO DEVICE NAME HERE"
Specify your audio device name, exactly as named in VLC. Use the name that you have noted in Step 7 of Installing VLC Standalone. Keep the quotation marks.
|:dshow-size=1920x1080||Specifies the resolution VLC will run the stream in. If needed, modify the resolution in the command to whatever needs you have.|
|:dshow-aspect-ratio=16\:9||Specifies the aspect ratio VLC will run the stream in. If needed, modify the resolution in the command to whatever needs you have.|
Note: For duration, what is specified during the campaign creation process is automatically inherited by the bundle within the campaign. Basically, setting this campaign to 15 minutes of play will result in the ad copy to play for 15 minutes.
Once Broadsign Control Player reaches this campaign in the loop, it will execute VLC, and run the command parameters that have been set. It will then begin playing the stream from the video capture card, automatically for the duration specified within the campaign. After the expected duration, VLC will dismiss, and proceed to the next campaign in rotation.
