Microsoft has included video and audio players with Windows for decades, but Windows 10 and 11 can't play some media formats without extra (paid) packages. Some audio and video codecs require a paid license to use in commercial products (such as Microsoft Windows), so instead of lumping all those costs into every copy of Windows, you might see a link to a Microsoft Store page for a media codec when playing some files. Fortunately, at least some codec packages might be free for you.
High-Efficiency Video Coding, also known as HEVC or H.265, is one common media codec that is not free to use in commercial products. However, as pointed out by Froggypwns on Reddit, many graphics cards ship with a license to use HEVC, meaning you might not have to buy it again on your PC. To find out, just open the Windows Run dialog (press the Windows/super key and 'R' at the same time, or right-click the Start Menu and click 'Run'), paste the following URL, and press Enter on your keyboard:
If your PC doesn't include an HEVC license, there are plenty of other ways to play media with that codec (and other proprietary media formats) on your Windows PC. The most popular option might be VLC Media Player, which is a free and open-source media player that can handle just about any video or audio format imaginable. You can download the Windows version from the official website, and while VLC is also available on the Microsoft Store, the Store version is a UWP application with fewer features. You're probably better off with the normal desktop VLC app.
I've found other reddit threads discussing this but none of the links provided worked. I'm using win 11 and i know i can just use VLC or something but i need the cast feature that's built in the windows media player.
K-Lite Codec Pack is a free and popular codec pack used to support a wide range of video types. It include advanced video codecs including H.265/HEVC, VP9, ProRes, Huffyuv, Cineform HD, Indeo, Lagarith, GoToMeeting, DNxHD, and many more. Similarly, K-Lite offers four packages: Basic, Standard, Full, and Mega. The HEVC pack is compatible with Windows Media Player and other DirectShow players.
We have shown all the solutions to the HEVC/H265 Windows Media Player playback issue in this post. Whether you install an HEVC video codec pack, convert HEVC to WMP-supported formats, or use a Windows Media Player alternative player, all can help you play the HEVC videos smoothly and without error. But if you encountered video/audio not opening issues in other devices or applications, you can really get the video converter to change file formats and codecs for better compatibility.
Codecs are essential for streaming media. Without codecs, you're unable to play videos on your device, which also limits you from editing or filming in specific formats yourself. For example, on a device without codecs, you'd be unable to record through your webcam or play media you downloaded or received.
Nowdays, more and more media players like VLC, Potplayer, 5Kplayer have add native support for HEVC codec. However, Windows Media Player is an exceptation. You will usually get a blank screen while trying to play H.265/HEVC videos on Windows Media Player. In such a situation, you can turn to other video player software like mentioned above to watch H.265 videos. What if you insist on using Windows Media Player?
Luckily, there are always solutions there. If you learn to install H.265 codec with Windows Media Player, you can apply the same principle for other media players. Goto this website to top up your WMP software with an advanced codec pack called Media Player Codec Pack Plus.
Answer: Back in 2016, Windows 10 gets native support for High Efficiency Video Coding (HEVC), making it easier to deal with 4K media. But there are still a large number of popular media player services do not support HEVC, such as Chromecast, Apple TV, 3rd Roku, Xbox 360, etc. So how to play H.264/HEVC videos smoothly? Here 3 solutions are offered.
1. Free download H265/HEVC codec. HEVC codec will help to compress/decompress videos in HEVC and makes HEVC playback possible. Right now, there are many choices available, such as x265, DivX HEVC, K-Lite Mega codec park, etc.
2. Install HEVC player. There are many media player adding support for HEVC, such as 5Kplayer, Potplayer, etc mentioned above, which are built-in many codecs, including H.265, so that you can play various videos of any resolution or format.
3. Take advantages of HEVC decoder. Video decoder helps to decode video into a format recognized by your computers, media players, game consoles, mobiles and tablets. And an HEVC/H.265 decoder also helps to decode HEVC/H.265 videos playable on your wide-screen mobiles. Famous HEVC decoders include Handbrake, EaseFab Video Converter, etc, which work as both HEVC encoder and decoder to convert videos to/from H265 smoothly.
In addition to being free to use under the GNU GPL, x265 is also available under a commercial license from MulticoreWare Inc. Software using x265

If you want to play HVEC video on Windows 10, using the Windows 10 media player, yes you need to purchase that H.265 Codec. However, that H.265 codec is only for the Windows Movies & TV app - nothing else.
Windows Media Player application: Enables Windows Media Player features, such as the ability to play media files and audio CDs, manage media in a library, create a playlist, provide metadata (including album art) for media, create an audio CD, transfer music to a portable music player, and play streaming content from a website.
VC-1, MPEG-4, and H.264, H.265, and H.263 codecs: Collectively known as "Standards-based codec components." Enable Windows 10 programs such as Windows Media Player to support activities that include the playback and recording of multimedia files that are encoded with standards-based codecs.
I think Ring have recently installed something in their wrapper for Event History that is preventing playback in some of the browsers, probably because it is non standard HTML5, since it was working and is now not any more. Mozilla appears to have the best documentation on this wrapper issue. Web video codec guide - Web media technologies MDN
the Event History is now not working for playback from my ring Stickup Cam (a new replacement as of January). It was working fine when I first installed the camera. I have various laptops and a fast desktop PC all running Windows 11, and fully up to date. The issue remains the same on Edge and Firefox. However it is now playing the Event History timeline videos fine again on Google Chrome on the desktop. (It has never ceased playing back fine on Google Chrome on my Pixel smartphone).
I have tried updating the Windows codecs and that has made no difference.

Hahahaha such a bullshit ... ? Ryzen 5 3600 is too weak for 4K+ videos on RTX2070 Super !?!? Are you crazy ?? ???
dizzyMongoose my friend just dont listen these bullshits - your hardware is more then enough for smooth play of 8K vids. The problem is in deovr versions over 9.xx . But here you wont get any support from the developers.
Just try to downgrade to 8.xx version or try different video player . Dont mess with that LAV codecs bullshits too .
Now when I play a 3630p 10 bit video in Windows Media Player, the playback is insufferably slow and jumpy. The CPU usage drops to 65% to 80% !! Meanwhile the GPU decoder usage is still 0%.
This means the Microsoft Media Player (with HEVC codec) also suffers from the same issue like DeoVR player ! It's in fact worse, because in DeoVR at least I can make the GPU do the decoding, but in Windows Media Player, there is nothing you can do.
I'm sure they're using the HEVC codecs though, because otherwise they would run really poorly on my rig.
One VR player says that it's using "Media Foundation" to play them, I'm assuming that's basically without DirectShow and it works fine.
So basically, I have no idea where the problem lies at this point, but at least other players seem to work.
I got a Ryzen 5 2600x and a GTX 1650 Super.
My guess why this fix works:
Once you turn off "DirectShow" in DeoVR, the player will use HEVC codec to play the video, and HEVC supports DXVA2, which fully supports 10bit decoding. So you will finally see smoothly playing 10bit video in DeoVR.
The HEVC codecs are no longer available for free on the Microsoft Store. You must download a third-party video player like VLC to play back HEVC video files, or pay the 99 cents for Microsoft's official codecs. We recommend against downloading the official codecs from unofficial sources.
These codecs will let you watch those videos on your PC, but they're only necessary for apps like Microsoft's Movies & TV video player, included with Windows 10, and other Windows apps that take advantage of the codecs built into Windows.
Microsoft has finally pulled the free HEVC codec from the Microsoft Store. Unfortunately, that means you must now either pay the 99 cents for the other codecs available from Microsoft or opt to use a third-party video player, like VLC, to play back videos encoded with H.265.
There are many possible reasons for a media player to fail playing when you try to open a video file with it. It could be the file being damaged, the player application being improperly installed or the lack of a certain codec. Among them, the lack of codec is the most common and the most possible reason for Windows Media Player to be unable to open an HEVC video file. In that case, installing the corresponding codec pack for Windows Media Player should solve the problem quickly and easily.
