Sharing media content

With TrueConf Room, you can share content from a source selected in the settings, which can be:

  • content from Apple devices (using AirPlay technology for content or screen sharing);

  • Capture card (via HDMI)

  • Any of the cameras connected to the device (including a PTZ camera)

  • NDI stream.

A number of conditions must be met for AirPlay to work:

  1. content/screen sharing is available from an Apple device running iOS 11.0 or later or macOS High Sierra or later;

  2. additional software must be installed on the PC running TrueConf Room: Bonjour for Windows or Avahi for Linux;

  3. The PC with TrueConf Room and the Apple device must be on the same local network (preferably the same subnet) and must be able to access each other by device name using mDNS technology.

  4. as a result, if your wired and Wi-Fi connections are in different subnets, the router must have an mDNS relay (proxy) configured to forward broadcast discovery requests;

  5. UDP and TCP ports 49152–65535, UDP 5353 (for mDNS), TCP 80, 443, 554, 3689, 5000, 6000, 7000, 7100 must be open in the local network for screen sharing. For more details, see Apple documentation.

The display device is selected in the terminal settings at the path Settings → Video → Default content source.

To share content during a call, click the Slideshow button in the meeting control panel and select Switch to content.

To display content on the main screen of a meeting room instead of the camera view (self-view) outside a call or conference, simply click the Switch to content button on the main page of the control panel.

Screen sharing via AirPlay

You can wirelessly share the screen of your macOS device (such as MacBook or Mac Mini) using AirPlay technology. The Screen Mirroring feature will be useful if the required application does not support native AirPlay streaming.

  1. Go to the TrueConf Room control panel and select the Settings → Audio & video → Content section.

  2. Enable the AirPlay option:

  3. (Optional) you can protect the terminal TrueConf Room from unauthorized connections: in the Authorization type section, select Password. Then, when connecting via AirPlay, a 4-digit code will be displayed on the terminal screen, which must be entered on the device:

  4. On a Mac, open the Control Center section and select Screen Mirroring:

  5. Once connected to the terminal, a window with settings will appear:

  6. Select the display type (for example, the entire screen), and the conference participants will see the content you have selected:

Streaming media content via AirPlay

The TrueConf Room software terminal supports AirPlay technology, which makes it easy to stream content from Apple devices directly to the terminal screen. You can display images, videos, audio, presentations, and any other media content.

Make sure that the AirPlay option is enabled in the TrueConf Room Settings → Audio & video → Content section. Additionally, you can protect the TrueConf Room terminal from unauthorized connections. To do this, select Password in the Authorization type section. After that, when connecting via AirPlay, a 4-digit code will be displayed on the terminal screen, which must be entered on the device.

To start streaming content from your device, tap the AirPlay /docs/room/media/gui/airplay/en.png button in the app interface. For example, in the Photos app for iPhone, follow these steps:

Please note that the name of the TrueConf Room terminal in the AirPlay menu will correspond to the Meeting-room name entry.

Content can be streamed from any AirPlay-compatible application, such as VLC player, YouTube, or PowerPoint.

Showing slides and documents

TrueConf Room allows you to show slideshows during video conferences.

TrueConf Room supports importing the following image formats for slide display: .jpg, .jpeg, .jpe, .jif, .jfif, .jfi, .png, .gif (single frame), .webp. It is also possible to import ppt and pptx presentations (Windows only), slides from pdf and .odt files, as well as slides files of a special format saved in the client application TrueConf.

Please note that to display slides in .ppt/.pptx format, PowerPoint must be installed on the PC where TrueConf Room is running. If PowerPoint is not installed, follow the installation instructions below:

  1. Subscribe to Microsoft 365 (or purchase PowerPoint separately) on the official website.

  2. Sign in to your Microsoft account (the same one you used for the purchase).

  3. Go to Install Office → Apps → and download the Office installer.

  4. Run the installer and PowerPoint will be installed along with other Office applications.

Importing presentations in .odp format requires LibreOffice version 7.5.0.1 or later installed on your computer.

The office suite must be installed to the default path suggested by the installer.

Due to a known issue on the LibreOffice side, importing does not work with versions above 25.2.6. This means that the latest working version of LibreOffice is 25.2.6. We recommend that you do not update the office suite until the issue is resolved on their side!

You can upload an image or a slideshow in several ways:

  • before a video conference — in the settings menu TrueConf Room under the Tools → Slideshow section;

  • during a video conference — the Slideshow → Slide management → Add slides button in the conference control panel.

After that, you will see a window with the added slides:

  1. List of slides

  2. Actions: Add slides and Clear all.

  3. The Start button starts the slide show.

  4. Buttons to change the slide displayed: thumbnails and one full-screen slide

You can change the order of uploaded slides by dragging them.

To start a slideshow, click the /docs/room/media/gui/share_presentation_button/en.png button at the bottom of the screen. The displayed image will expand to full screen:

When viewing thumbnails, the /docs/room/media/gui/circle_in_slide/en.png icon is displayed in the top right corner of the slide being broadcast. If you return to the conference control panel, a similar icon will blink on the Slideshow button.
