Free HEVC Video Extensions from Device Manufacturer Install HEVC video extensions in windows 11 Option 2. Though a small portion of users are complaining that they've bought the codec but it won't launch or open. Once the HEVC codec is installed, you can then play HEVC videos on Windows 11 without problem. It will require your Microsoft account and credit card. Click Buy and follow the instructions to finish the purchase. To install the official HEVC codecs on Windows 11, open Microsoft Store app or website and find the HEVC Video Extensions. If you usually use apps like Microsoft's Films & TV Player app to play videos, it's a worthwhile investment. How to Download and Install HEVC Codec on Windows 11Īs Windows 10 and 11 do not contain the codecs to play HEVC videos, Microsoft provides the required HEVC Video Extensions in the Microsoft Store. Decompression of AV1 is much faster but still for seamless performance the user needs a hardware codec.Free Download for macOS 12 or earlier Option 1. The other larger problem with AV1 is that while it does have better compression, the CPU requirements to create an AV1 video are enormous and out of the question for older CPUs. However, there are very few machines that have support for it, they have to be Intel Tiger Lake or better CPUs. If their extension ONLY used the CPU's codec then they would NOT need to pay a patent fee to MPEG LA and they would not have to charge 99 cents and then fork that over to MPEG LA.īecause of the exorbitant patent fees for HEVC, the major CPU manufacturers are moving to a new codec created by Alliance for Open Media which does even better compression of video. I know for a fact they DO have a software HEVC in the 99 cent extension because I have it running on a pre-Kaby Lake CPU and Edge does in fact display H.265 video with it (it did NOT prior to loading that app) I don't know why Microsoft is charging the 99 cents but I am pretty sure it is because they compiled in a software HEVC codec in their app, and if for whatever reason Edge can't use the hardware codec in the CPU it switches to the software codec. One warning about using distributions like this is since you don't know who compiled them they might have spyware embedded in them so be careful. There is currently one such distribution active in an overseas location you can search for if you want to avoid the 99 cent fee and you have a CPU that is pre-Kaby Lake. A few people have done this and put up distributions for a while until they either lost interest or MPEG-LA filed takedown requests. Because the source of Chrome is open source, located at it is possible to build this along with one of the open source codecs and create a version of Chrome that supports H.265 regardless of whether or not the CPU has a hardware codec in it. There are multiple open source H.265 software codecs available but according to the convoluted licensing on the HEVC patent, anyone building a working codec from those free sources is liable for patent royalties. However, I have not found this to be true under Windows 10. SUPPOSEDLY the latest version of Chrome will also play H.265/HEVC videos IF the CPU has a hardware codec for HEVC, without having to buy this app. This does in fact work with the latest version of Edge to play H.265 videos. This app SUPPOSEDLY will use a hardware decoder in the CPU if one is present, and if one is NOT present then it WILL decode using a software decoder that runs as a process in Windows. The OTHER codec is "HEVC Video Extensions" This is a PAID app that costs 99 cents. It is NOT a license fee issue because the license fee for the HEVC codec would have already been paid by the CPU maker. I do not know if this is because they intended to break its compatibility with Edge or for some other reason. They finally removed all references to it from the Store. However, Microsoft discovered that people could install this on any computer regardless of the CPU by going to the Store. This app USED to be visible in the Microsoft Store. Only Media Player/Windows Media Player still can use it. However, it APPEARS that the latest versions of Edge - 1.56 as of this writing - are unable to use this codec. SUPPOSEDLY it also allowed for playing HEVC videos - such as 4k videos from Netflix - in the Edge web browser. The reason it was free is because - allegedly - it ONLY worked with CPU's that had the H.265/HEVC hardware codec in the CPU itself. It allows for playing of H.265 videos in Windows Media Player. If you have that on your system, then Windows Updates will automatically keep it updated to the latest version - as of this writing it's 1.0 It was included in some of the older earlier Windows 10/Windows 11 builds and installed automatically when those builds were installed on a new system that - apparently - had an Intel Kaby Lake or later CPU. The Device Manufacturer one is the original one. One is 'HEVC Video Extensions' and the other is 'HEVC from Device Manufacturer.'
