Video does not work.

The reasons for this may be different, but conditionally they can be divided into three large groups: reasons on the server side, reasons on the provider side and reasons on the user side (that is, you).

If you have does not download the video in contact due to problems on the server, then the problem is most likely to be observed withseparate videos (because the site is located on a large number of servers and different videos are uploaded to different servers). This video on other sites (for example, YouTube) will play normally. In this case, you can not do anything - you just have to wait until the problem on the site is solved.

Another reason that you do not have VKontakte video, maybe low speed internet, in which the provider is most often to blame. In this case, the video is loaded on slightly, as if by jerks, and sometimes it does not reproduce at all.

If you need to view the video right now, try choose lower quality playback. If this does not help, measure the speed of the Internet. If it turned out to be too low, contact your service provider's technical support and solve the problem with it.

But the most common reason that does not show the video in contact is problem with the user's browser (you can check this by trying to reproducevideo using another browser). Most likely, you either have an older version of the plug-in to view the flash video, or one of the installed add-ons for the browser does not allow the video to play normally.

If you do not have the latest version of the browser installed, update it to the current version. You can try to reinstall the browser (remove and install from scratch), but do not forget to save the bookmarks before, so as not to lose everything acquired by overwork.

Also it does not hurt to reinstall Adobe Flash Player; It is advisable not to install a new version of the player above the old one, but completely remove the old one and only then to install a new one.

Also, the problem may be the conflict between the drivers on the video card and the flash player. To solve it, right click on the video, select "Options" in the context menu and uncheck "Enable Hardware Acceleration".

You can also try disable ad blocking plug-ins. By the way, they can be a part of both the browser,and an anti-virus program or firewall, so think about what programs installed on your computer can block the flash content, and temporarily disable them all. If the problem was exactly this, you will need to add the vk.com site to the exclusion list of the corresponding plug-ins / programs.

If you have any Add-ons for downloading audio or video from the site, try disabling them and check if the video will play. Of course, you can say: I have a long add-on, and problems with video playback appeared only now.

But the fact is that the site is constantly evolving and developers can make certain changes regarding video playback. If the developer of the browser plug-in has not managed to update it in the light of the latest changes on the site, there may be problems with playing the video.

Finally, clear your browser's cache and check the computer for viruses: it will not get worse from this, but in some cases it helps.

In order for you to experience video playback problems as rarely as possible, you need regularly update the browser and flash player, making sure that you always have the latest version of software on your computer.
