Buffering

In order to keep video playing smoothly, we download a small amount of video ahead of your current playback so we can continue to play video if your connection is momentarily disrupted. Unfortunately if the connection is disrupted for too long, we need to pause playback to “rebuffer” video. This is what is commonly referred to as “buffering”. On Mixer, you’ll see a pulsing blue circle when streams are buffering.

Buffering can be caused by dozens of different things and unfortunately it’s often times very difficult to pinpoint the root cause. Since the internet consists of a series of providers all passing traffic between each other, it’s possible for any one of these intermediary providers (including our servers, and your ISP) to become saturated with traffic. It’s also possible for buffering to be caused by local problems, like browser plugins, firewalls, routing equipment, and proxies.

For more information, read our overview of how video delivery works on the internet.
