You would have to write your own player app. WinRT doesn't seem to have a way to share functionality with other apps except by contracts. Microsoft would have to create an MKV container codec for the Xbox Video app and bundle it inside the package.

The Matroska splitter doesn't work because there isn't a way for an app to use regular Win32 DirectShow filters.

So I'm guessing there's no media playback type contract? It sounds like the Xbox video app is much like the zune client software in that regard since it can't play mkv either iirc.

As the MS blog post on this states....

"During the development of Windows 7 we talked quite a bit about CODEC support natively in Windows and the formats available through extensibility. Since then, the environment around CODECs has consistently moved towards a smaller set of well-defined and broadly-supported formats, particularly h.264 for video. Due to factors such as intellectual property and hardware support, this makes a great deal of sense. Even browsers are making this transition with HTML5. But we also recognize that some individuals have preferred formats for a variety of reasons, and we wanted to make sure Windows 8 app developers could choose to use the formats they prefer. Formats popular among the enthusiast community or with specific developers such as FLAC, MKV, and OGG, can have their own CODECs packaged as part of a Metro style app, since the Windows 8 media platform is highly extensible."

Basically someone needs to write a "metro", or rather, winrt? mkv splitter/codec. Most if not all mkvs are your normal h264 which IS supported by the new media platform. In either case, they're not working for you right now because no codec has been writen to work with the new media platform in metro. The desktop side is the same so any desktop apps will just work like they have been.

Give it some time and someone will port their mkv, flac and even ogg codecs/splitters for the metro video app I bet.

I think that no one has read this post. Metro apps require other ways to work with, so people will have to wait till codecs are written for metro apps.

To be more precise, you'll have to do an app that can play MKV files, it won't be a codec inside the video app made by MS.

Seems like it, but maybe you can just have the built in player pass mkv playback to the other app, do mkv files not show up in the xbox video app at all?

Well, FYI, I was unable to playback any mp4 files in the new Metro video player app, however, the normal Windows Media Player app played it perfectly.

It was a standard mp4 with h264 stream, that also playbacks perfectly in QuickTime Player X.

Have to say that I am pretty tired to still resort to third-party apps and codecs to playback normal video files. And I bet cover art and subtitles still do not work by default in Windows 8. As long as MS goes this route, it's hard to take their OS seriously.

Are you on RTM? If MP4 doesn't play, then surely you are not on RC...

MP4 is a container format. They're working fine for me with h.264 video (RTM build). But there are probably some more obscure codecs which won't work (at least out of the box).

It all depends on the type of h264 encode that was done for that mp4 file. The built in codec is pretty specific in the type/profile it supports. If you move away from that, even if it's still h264 it probably won't play or won't play well.

I think if it's a non-standard MP4 (h.264 + mp3 for example), it won't play. I think I have played MP4 (h264 + stereo/5 channel AAC audio) and AVCHD (h264 + ac3) just fine. Most MKVs are just h264+ac3 and if you use something like tsMuxer to convert MKVs to AVCHD (.MTS or .M2TS), they will play fine although you will lose all subtitles track.

Should be rare though I would assume. I mean if someone encodes something and uses Mp4 container, it should imply compatibility. Just like if someone uses an AVI container, you do not expect an h264 video stream. Maybe I am a tad naive here.

MKV has more overhead. MP4 is indeed superior.

No clue why, I spend too much time looking at task manager.

If by superior, you mean far more limited, then you are indeed correct..

MKV is probably the best container out there. It supports all, or damn near all audio, video, and subtitle formats, loading of external files (if you use the right splitter.. this means you can encode the intro to a series once, and every episode encode will just call that file when it's needed.. saving space ).. also ordered chapters, meaning you can have more than 1 version of a movie at a time.

MP4 has a lot of limits on formats that can be used in it, it's not nearly as flexible, but it's also not the container of choice for "pirates" and as such, is more widely supported..

Less Overhead

More Compatibility

Can be more assured will play on vanilla Windows install

Satisfactory for most everyone, except pirates

Overhead.. lol.. Ya it uses an extra 0.5% cpu :p

Everything beyond that is who cares ? The idea that everyone should switch to it because you find it more satisfactory is absurd..

What if I want Chapters ? Subtitles ? FLAC Audio ? DTS ? Any of the HD Audio Formats [ TrueHD, DTS-HD, etc ] ? How about 3D Support since that is getting popular..

How about if I don't want to pay the MPEG-LA for the rights to use it in my hardware ? MP4 is not a "free" container, it's full of patents.

MKV is superior in every single way outside of Native support. Why ? Because pirates use it.. why? Because it's Better.

It's the same reason it took a while to get MP3 support in lots of hardware players, or Xvid/DivX support..

I've encoded or remuxed almost all of my DVD's and Blurays into H264 MKV's.. Best video with best audio, chapters, subtitles if needed. Telling me or anything else to go backward to MP4 is like telling people to go back to AVI, or RM. It's inferior, in almost every way.

And beyond all of that, I don't want MS telling me what formats I am allowed to watch. Didn't they just announce a new H265 format in the works for even better quality and smaller filesize.. OH but you can't use it because MS doesn't allow it's app to use normal codecs the system has, a system that was designed to that ALL programs could have access to and decoders/splitters/etc that you chose to install.

It would be like Microsoft having the favorites folder for IE in your personal folder, only making the Metro IE need a whole new list in a new folder.. it would be nothing but a hassle. Just as this is.

modern apps use mediafoundation not directshow. all the old codecs are directshow. if there are MF codecs then they will work in modern. and btw windows 8 enterprise doesnt include media foundation,so no media apps work

Really? Now that's something I didn't expect, you would think Enterprise version would have everything in it the other ones have.

    • Apple and Tesla trade secrets reportedly exposed following a Tata Electronics cyberattack

      By Hamid Ganji · Posted

      Apple and Tesla trade secrets reportedly exposed following a Tata Electronics cyberattack by Hamid Ganji Image via Depositphotos.com Tata Electronics has confirmed that it detected a cybersecurity incident in some of its systems. The Indian company is a manufacturing partner of both Apple and Tesla, and the incident may have exposed some trade secrets belonging to the two American companies. The World Leaks ransomware group is said to be behind the attack, and it has reportedly posted up to 200,000 files on the dark web, including component designs and specification documents related to Apple and Tesla products. Tata Electronics told Reuters that its response protocols were deployed immediately and that the “incident has had no impact on our operations across businesses, which remain unaffected.” The ransomware group reportedly sent a ransom demand to Tata Electronics, while Apple has launched an investigation into the incident. World Leaks claims it stole more than 200,000 files totaling over 630GB from Tata Electronics. Some database files on the ransomware group’s website are titled "com.apple.factorydata," which could refer to Apple’s iPhone production operations in India. Moreover, some documents reportedly contain material specifications and quality inspection standards for iPhone circuit board components. However, Apple is not the only affected company. A folder found in the World Leaks database is titled "NV36 Chargeport Controller - North America," which may refer to Tesla Model Y components. Additionally, other files in the database reportedly contain drawings related to Tesla’s Project Highland, the internal codename for the EV maker’s updated Model 3 sedan. To support the authenticity of the stolen files, World Leaks has published documents containing footers that read: "This document contains proprietary and confidential information of Apple Inc." and "information contained herein is deemed confidential, proprietary, and a trade secret of Tesla Inc." Cybersecurity researcher Rajshekhar Rajaharia told Reuters that the database also contains emails, event logs spanning several years, and passport copies of employees, including foreign nationals. Both Tesla and Apple have declined to comment on the scale of the incident.
