";s:4:"text";s:6229:" How Can We Help? If the speaker’s audio is low, FreeSWITCH might take a moment to recognize that someone is speaking before transmitting, causing others to hear your audio only after you have started speaking a few words.You can also change the settings on FreeSWITCH to lower default threshold for audio. You can see the list of recordings withThe HTML5 client now enables users on mobile devices to connect to a BigBlueButton server. You don’t need to learn all these languages to help out, but you should be very comfortable programming in Java as JavaScript, Grails, and Scala are all similar to Java.Before you can contribute as a developer, you need to invest some time into understanding BigBlueButton’s Like other open source projects, a good place to start is to try fixing an Some bugs are more important than others. Some of us also work for companies that provide We want to make BigBlueButton the leading open source web conferencing system for on-line learning.
Have the switch to a wired connection, if possible, or move closer to the wireless base station.Also, if the user’s client takes over a minute to load, they are likely tunnelling through port 80, which will further degrade the audio.In general, if all users are encountering audio problems, the issue might be with the BigBlueButton CPU being overloaded or the bandwidth to the BigBlueButton server is saturated.If a specific user is having poor audio quality (i.e.
We recommend 1 Gbits/second bandwidth in both directions.When sharing a webcam as a moderator, BigBlueButton lets you select 320x240, 640x480, or 1280x720. When we create a conference, there is no sound attached. Why is this the case? To use this test server, just accept the default settings when configuring the activity module.
only their audio is choppy but everyone else sounds good), have the individual do a speed test. preface to a quiz or a group of questions within a quiz. Without a simple-to-use (we like to call it elegant) user interface, BigBlueButton would neither be adopted, nor viewed as a compelling alternative to more complex (and proprietary) equivalents.Features are the focus of each release, and we focus on the features that our core market (on-line learning) will benefit from most.Modularity enables components of BigBlueButton to be developed, refactored, and upgraded in parallel. A text (no question) quiz question can be used as a To resolve connection problems, see question below.If you are running BigBlueButton on EC2, then note that EC2 uses both a public and private IP address. Next, execute the following two commandsWhen running in a container (like a chroot, OpenVZ or LXC), it might not be possible for FreeSWITCH to set the CPU priority and other tasks is not possible.If you see an error starting FreeSWITCH, try running One possible cause for this is you have just installed BigBlueButton, but not restarted it. For bandwidth calculations, each resolution corresponds (roughly) to a .25 Mbits/sec, 0.40 Mbits/sec, and 0.60 Mbits/sec video stream respectively.For example, if you have a room with 5 users, each sharing their webcam at 320x240, then you can calculate the bandwidth usage as follows:For example, with 5 users in a room with 5 webcams streaming, the bandwidth calculation is as follows:If you’d have a typical classroom situation one presenter broadcasting their webcam to 30 remote students, the calculation is as follows:Large “cafe-style chatroom”: 20 viewers, 8 people broadcasting with a webcam:Sharing slides takes almost no bandwidth beyond the initial uploading/downloading of slides.

However, the user’s network settings (or firewall) may not allow WebRTC to connect (or keep connected).Here are the following lists the possible WebRTC error messages that a user may encounter:Chrome requires (As of Chrome 47) that to access the user’s microphone for WebRTC your site must be serving pages via HTTPS (that is, nginx is configured with a SSL certificate).If the user attempts to share their microphone and your BigBlueButton sever is not configured for SSL, Chrome will block access and BigBlueButton will report the following errorTo enable Chrome to access the user’s microphone, see When you attempt to join a BigBlueButton session, the client looks for supported browsers before fully loading. One of the server requirements before you install BigBlueButton is that port 80 is not in use by another application (such as Apache). You can click the phone icon twice – once to leave and a second time to rejoin – to try joining the audio again. At the low end, if the presenter’s screen is largely idle, the screen sharing application will transmit about 0.2 Mbits/sec; at the high end, if the presenter’s screen is updating frequently, the BigBlueButton server could transmit 1.0 Mbits/sec. The decision of expanding the committers group rests with the committers.Each release cycle goes according to the following steps.During the planning process, the committers decide on the main features for a release by reviewing the We review the features according to the development priorities for our target market (see After the planning phase, each feature for the release is assigned an issue in the BigBlueButton Issue Tracker (if it does not already have one). Both browsers provide excellent support for web real-time communications (WebRTC). This work usually occurs when we want to enhance a feature (we usually refactor it when doing so) or add new capabilities (such as refactoring the underlying messages to support the HTML5 client).If your feature belongs in category (3), you have options. red5).
