How to avoid buffering in video?

Can't be avoided though can be made a bit quicker.Buffering or live streaming is just like downloading the embedded video onto your browser and a way to quicken it, is to have a higher bit rate which is possible through fast internet connection.
.
Another technique is to close all other applications that are opened on your PC and delete the browsing history.This would speeded up the streaming to some extent.
.
There is another way to.Go to your browser properties and see the allocated Disk storage space for internet browsing.If you increase it,you'll get a difference.

Get a really fast internet connection..:D

Close your eyes and go to your "happy place."

The faster your connection, the faster the buffering will be.
There is no way to completely eliminate it.
You can only see a video if you have at least a part of it downloaded, and this is what buffering does.

Some sites may provide you a download version of the video, or with the help of some tool you might be able to download it. That way you can store it in your computer and you won't have to buffer it to watch it.

YouTube for example, there a tons of tools to download the videos, just search for "youtube downloader" or something like that in Google.

Buffereing is a common problem on live streaming websites like youtube and meta cafe. Its my personal experience that buffering a video can only be stopped while having a fast internet connection, at least more than 1MBPS
