How do I playback .MKV in Windows 7/Windows Media Player 12?


Recommended Posts

Hey

I was wondering how do I playback the MKV container format on Windows 7/Windows Media Player 12? The only solution Ive seen so far is installing CCCP but I dont want to as everything (except this) works perfectly in Windows 7/Windows Media Player 12.

Also Explorer thumbnails would be nice :)

Windows 7 Codecs is all i've ever needed in Windows 7 to play anything. You could also probably download FFDSHOW and use that :)

The nice thing about Windows 7 Codecs is that it doesn't mess with the already working codecs at all....

Your link is messed up :wacko:

You dont need any codec on Windows 7. Everything/anything (97%) plays out of the box. If you install a codec pack, you are asking for trouble. I havent needed ANY support in the codec area minus Realmedia files (that was a given) and MKV files. Everything else has played back perfectly.

I perfer not to install anything from DivX.

What about like maybe going to.... mkv's official site and hitting "downloads" link?

CCCP (Combined Community Codec Pack)

Comment:

Almost all you need to play .mkv (matroska video) and .mka (matroska audio) files under DirectShow players, such as Windows Mediaplayer, MPC, Zoomplayer and TCMP

I agree with them. CCCP supports most of video formats AND doen't mess your system like other codec packs (https://www.neowin.net/forum/index.php?act=announce&f=12&id=11, etc).

CCCP pack is basically Haali Splitter and a special build of ffdshow. Most .mkv files either contain .H264, .x264, or .xvid. The only codecs I have added to Windows7 is Haali, flac, and Monkey's Audio (.ape). I use mplayer for anything that won't play in WMP. I have found it to be much better than VLC or even KMPlayer.

2006 is the last time it was updated? Look at the home page Quazzi posted.

Research before you post please

It actually does. It has some issues in WMP where you hear all the background noise and music but you dont hear any of the dialog at all on some video files. So I perfer not to install CCCP since my system is working great now.

Ill try your method Quazzi :)

I know you said how to play it in wmp but VLC has never let me down. Just thought I would throw that in. Not the best GUI in the world but its the movie your watching that matters
VLC is also what I would use, the only thing I've found what won't play on it out of the box is .rm files, but you can use Real Alternative w/MPC for that anyways.

Thank you for mentioning VLC but I use WMP :)

Again, I perfer not to use CCCP.

So I have to install the Haali Media Splitter and the AC3 filter? I dont want to install them just to make sure this is all I need :)

You don't have to have AC3Filter, just need the Haali Splitter.

@Bob21: Tried out mkv2vob since you are ALWAYS posting about it... caused explorer.exe to continuously crash in a infinite loop. Deleted the mp4 it outputted and problem went away.

Im sure it did :rolleyes: just more myths lies and propaganda to promote rubbish unsupported containers.

Well you people have tried just about everything else...

Regardless the method above solves OP's problem dosnt change the quality or filesize and without the use of any splitters codecs or players, And the rusulting files will play in any software player/editor and pretty much anything with a screen (every console/Streamer/Bluray/PMP/PDA Phone...) :p

Guess I'm lying to support something in some made up war of yours that I could give a rats ass about :rolleyes:

Fact is it happened. I tried it on your behalf just to see why you are so adamant to advertise it in every post you make here, but it didn't work. Bummer. I can play mkv just fine, and if that's what someone releases their stuff in then no problem with me :)

Beware the myths, lies, and propaganda!! :laugh:

    • Steam Summer Sale 2026 kicks off offering weeks of PC game discounts by Pulasthi Ariyasinghe Every year, one of the biggest events that Valve hosts is the Steam Summer Sale. Now, the 2026 edition has just kicked off, bringing discounts for everything from the newest games and retro gems to all sorts of DLC packs. As always though, PC gaming hordes have managed to shake the servers of Steam just as the sale opened its doors, so expect the prices, store pages, and services to not show up properly for some time till the backend stabilizes. You'll find sales being present, though with minor cuts, for even relatively recently released titles this time. The front page is the place to be for anyone looking for recommendations, with it putting a spotlight on fresh games every day. However, keep in mind that the discounts themselves will not be changing and will remain static throughout the sale. Blockbusters like Clair Obscur Expedition 33, Split Fiction, Red Dead Redemption II, Battlefield 6, Dispatch, Baldur's Gate 3, Resident Evil Requiem, Anno 117, Arc Raiders, Black Ops 7, Kingdom Come: Deliverance II, and much more are currently discounted. Valve has also brought back the special "Deep Discounts" section. While part of this same sale, it only highlights games that are discounted by at least 85%, with some titles even reaching 95% off. Some of the games included here are The Witcher 3: Wild Hunt, Watch Dogs 2, Far Cry 4, Wreckfest, Dragon Ball Xenoverse 2, The Quarry, Ghostwire Tokyo, Call of Duty: Modern Warfare II, and much more for just a few dollars each. The Steam Summer Sale of 2026 will be open for business until July 9, giving everyone two whole weeks to try and keep their wallets closed. If you want to see the biggest highlights, be sure to read our Weekend PC Game Deals special coming this Saturday.

    • Google reshuffles its AI coding team as it struggles to catch Anthropic by Karthik Mudaliar Google is already reorganizing the AI coding “strike team” it created roughly two months ago, as it attempts to find ways to close the gap with Anthropic in one of generative AI’s most commercially important areas. According to The Information, Google DeepMind is expanding the team’s focus to include “midtraining,” rather than concentrating only on coding tools and agents. Midtraining takes place after a model’s broad initial training but before the final stages that prepare it to follow instructions and perform specific tasks. In simple terms, it gives developers another opportunity to expose a model to carefully selected data before it is polished for release. That could help Google improve Gemini’s underlying coding abilities instead of relying only on better prompts, interfaces, or post-training. Previous research has found that midtraining can be particularly effective for code and mathematics, where models must move from general language knowledge to more structured tasks. Google reportedly created the original strike team in April. It was led by Google DeepMind research engineer Sebastian Borgeaud, who previously worked on model pretraining, and focused on complex, long-running programming jobs. Google co-founder Sergey Brin and Google DeepMind chief technology officer Koray Kavukcuoglu were also reportedly involved in the effort. DeepMind researchers were said to believe that Anthropic’s coding tools were outperforming Google’s Gemini models, prompting the company to give the project more attention. Anthropic has made coding a central part of its AI strategy through Claude Code and its Claude model family. The company has continued improving that area, with Claude Opus 4.8 offering upgrades for coding and other agentic tasks, along with the now-unavailable Mythos and Fable models. The reshuffle also comes at a time when Google faces increased competition for AI researchers. Gemini co-lead Noam Shazeer recently announced that he was leaving Google for OpenAI, while two other researchers who contributed to Gemini and DeepMind projects are reportedly preparing to join Anthropic. It remains unclear whether the reorganized team will produce a new public Gemini model or developer product. No release date, team size, or specific performance target has been disclosed.
