Regular ClickMeeting accounts are perfect for meetings and webinars, whether they are academic or company presentations, online lessons, or training sessions. Streaming is an additional feature available on-demand for customers who prepare big events and want to stream them online in the best quality. This advanced feature allows organizers to broadcast the live event using multiple cameras and camera angles.
One of the most important features in Live streaming is the ability to choose the quality in which the recipient receives the image. There are three image qualities available: HIGH, MID, LOW. The quality of transmission is selected by the recipient depending on the parameters of the bandwidth they have. The sender provides the image in the highest format which, on the side of the platform, is changed dynamically depending on the individual hardware and bandwidth resources of each user. By choosing the quality manually, the user takes control of transmission quality settings. This means that transmission quality is no longer adjusted automatically. Note that transmission quality on iOS devices is automatically set to 720p.
What are the differences between regular ClickMeeting audio-video settings and those for live streaming?
|Regular audio & video pod||Live streaming|
|Resolution||The resolution depends on the following parameters: connection quality, amount of available RAM, and processor capacity. It is adjusted dynamically during the event.||Image is delivered to the ClickMeeting platform in the best quality (max 5 Mbps, 1080p).|
Image delivered to the audience – a choice of 3 different streams, tailored to the attendee’s bandwidth.
LOW: 360p (400 kbps)
MID: 720p (2,5 Mbps)
HIGH: 1080p (4 Mbps)
|Camera||Only a web camera (you can use a regular video camera with a webcam emulator).||You can use professional cameras and mixers.|
|Frames per second (frame rate)||20 fps||30 fps|
|Wide screen (16:9) ratio||Available||Available (if needed)|
None. Minimal delays due to delays in data transfer. In case of major problems, delays in the picture may be compensated by dropping some fragments of the video.
|10 to 20 seconds. Caused by the need to buffer the image (collecting data on the server side as well as on the attendee side) to ensure the highest possible smoothness. Difficulties with the connection stop the transmission, rather than skipping some fragments of it.|
The recommended stream parameters are as follows: 1080p resolution, a bitrate of 3-5 Mbps, keyframe 1s.
Please note that a higher bitrate will not improve the quality of live streaming (and might even result in bandwidth issues).
To use the live streaming feature, you must have a streaming encoder installed, such as OBS. It’s free and works well for most of the cameras which our customers use. Alternatively, you can use Wirecast that offers some additional features.
You may use other encoders but be aware that ClickMeeting has only tested OBS and Wirecast encoders and cannot advise you on other solutions.
Tips & Tricks
1. Please note that the Live streaming feature does not replace the standard AV pod. Therefore, it is not possible to display the Live streaming image and other event room functions such as presentation, whiteboard, or screen sharing.
2. If you do not want to display the AV pod during your event with live streaming, we recommend that you hide it or have it disabled by reaching out to us before the event.
3. Choose Presentation under Recorder layouts if you need to record the event through ClickMeeting without unnecessary components (e.g. AV pod, top bar).
4. Please note that the Server URL and Stream name/key parameters might change. Be sure to verify them before you start a new event. If you enable live streaming multiple times during a single session hosted in a given event room, these parameters are unlikely to change. In case they do, a notification will be displayed the moment live streaming is enabled.
5. The event room and external software can be set up on separate devices. Thanks to this, you will avoid the impression of an unstable image on your side.
6. To synchronize the guide camera with the RTMP stream, you can use a virtual camera for the guide (e.g., via OBS) and set the same delay.
7. In case of connection or streaming issues try reducing the video stream bitrate to 2.5 – 3 Mbps.
8. CBR is best for live streaming encoding. We recommend you choose this type under Encoder settings.
