Many users, when trying to play a video on Youtube, receive the following message - “Currently your browser does not recognize any of the video formats.” Most often, owners of Windows XP with the Mozilla FireFox browser encounter a playback error. The problem is also observed in other popular browsers: Google Chrome, Yandex, Opera and, of course, Internet Explorer. Today we will tell you about all the possible causes of the failure and their elimination.
Reasons why playback fails
The bug itself appeared relatively recently. It is connected with the active transition of the YouTube service to support HTML5 technology, which is not supported in browsers with outdated versions. The error also appears in updated versions on Windows 7 and 10. Here it is worth talking about extensions that block access to displaying videos in HTML5 format. The third reason is that the new video didn’t have time. Let's look at all the solutions to fix the crash.
Fixing the error
Let's check all the above points one by one. I’ll note right away that I won’t describe all the half-measures (reboot, new Flash, erasing cache/cookies), because they won’t be of any use. You will need to check the following.
#1 Checking for updates
First of all, you need to update your browser to the latest version. The update principle is the same in all applications. But still, here is a brief instruction:
The current versions of these programs include most of the necessary video codecs for YouTube. You can check which ones are supported at this address - youtube.com/html5. Perhaps some codecs will have an exclamation point, but be sure to check that there is a checkmark next to the first codec HTMLVideoElement. The problem should go away.
#2 Blocking add-ons
If the previous point did not help you, try disabling unnecessary extensions. The fact is that various plugins and extensions can block display in HTML 5 format. For example, these plugins most often cause the problem - “Flash Player for YouTube™” And “Disable Youtube™ HTML5 Player”. Extensions for direct downloads, ad blockers, etc. also fail.
- Open a page with a list of installed extensions. For example, in Chrome it is located here chrome://extensions/, and in Mozilla here - about:addons.
- Disable all active plugins one by one and check playback. It should help.
I will separately mention Flash Player, which conflicts with new versions of Chrome. You should try turning it off too. If you still have an old version, then go here - chrome://plugins, In the list of plugins, select flash and disable it. In the new version we go here – chrome:/. In point "Block" there is an option "Add", I recommend adding YouTube there. For other browsers on the Internet there is a lot of information on disabling Flash Player - try it.
#3 New video
Check the release time of the video. If it takes several hours, then the problem may be on the server side. Many users note that after waiting a little time, they start the video without problems. Perhaps this is your case.
Conclusion
If you did everything correctly, the error “Your browser does not currently recognize any video formats” should disappear. Finally, it's worth mentioning that Mozilla and Chrome recently stopped supporting their application on Windows XP. In this case, to solve the error, you will need to separately install codec support plugins. Here is a visual video instruction using Mozila as an example.
Every day, search engines process thousands of requests asking them to fix HTML5 errors when watching videos. And it’s not surprising, because this technology is relatively new and is spreading at a rapid pace. We will tell you how to solve this problem below.
Player description
It’s no secret to many that to watch various kinds of videos, play online applications and perform other useful actions, you need special browser extensions. These include Adobe Flashplayer, Microsoft Silverlight, Ace Stream and Quicktime. The share of web elements that support the above technologies exceeds 90%.
But that was until recently. After the presentation of the new HTML5 standard, it became possible to play videos and other media content using the browser, without the participation of third-party plugins and additional codecs. The player supports all modern file extensions, including OGG, WebM, MP4 and others. 
If the new product is so good, why are there problems? The answer to this and related questions is located below.
How to fix the error?
In the vast majority of cases, the problem is an outdated version of the browser that does not support the HTML5 standard. To update your Internet browser, go to “Options” - “About” and click the “Check for updates” button.
If the application reports that you are using the latest version, but the date of the previous update is indicated more than six months ago, delete the browser manually and download a new one from the official website. 
But updating the application may not be enough. As an alternative, do the following:
That's all. Now you know how to fix HTML5 error when watching videos. If you know other ways to solve the problem, please share them in the comments.
