• - Atu - his, - a drawn-out cry of one of the stopped greyhounds was heard at that time. He stood on a semi-mound of stubble, raising a rapnik, and once again repeated drawlingly: - A - that - him! (This sound and the raised rapnik meant that he sees a hare lying in front of him.)
  “Ah, I suspect, I think,” Ilagin said casually. - Well, let's go, count!
  - Yes, you need to drive up ... yes - well, together? Nikolai answered, peering at Yerza and at the red Uncle Rugai, at his two rivals, with whom he had never yet managed to equalize his dogs. “Well, how will my Milka be cut off from my ears!” he thought, moving towards the hare next to his uncle and Ilagin.
  - Mother? Ilagin asked, moving towards the suspicious hunter, and not without excitement, looking around and whistling to Yerza...
  “And you, Mikhail Nikanorych?” he turned to his uncle.
  Uncle rode frowning.
  - Why should I meddle, because yours is a pure march! - in the village they paid for the dog, your thousandths. You measure yours, and I'll take a look!
  - Scold! On, on, he shouted. - Scold! he added, involuntarily expressing by this diminutive his tenderness and hope placed in this red dog. Natasha saw and felt the excitement hidden by these two old men and her brother, and she herself was worried.
  The hunter stood on a half-hill with a raised rapnik, the gentlemen drove up to him at a step; the hounds, walking on the very horizon, turned away from the hare; hunters, not gentlemen, also drove off. Everything moved slowly and sedately.
  - Where is the head? Nikolai asked, driving up a hundred paces to the suspicious hunter. But before the hunter had time to answer, the hare, sensing frost by tomorrow morning, could not lie down and jumped up. A flock of hounds on bows, with a roar, rushed downhill after a hare; from all sides, the greyhounds, who were not in packs, rushed to the hounds and to the hare. All those slow-moving hunters-snipers shouting: stop! knocking down dogs, greyhounds shouting: atu! guiding the dogs, they galloped across the field. Calm Ilagin, Nikolai, Natasha and uncle flew, not knowing how and where, seeing only dogs and a hare, and fearing only to lose sight of the persecution even for a moment. The hare was caught hardened and frisky. Jumping up, he did not immediately gallop, but moved his ears, listening to the scream and clatter that suddenly resounded from all sides. He jumped about ten times slowly, letting the dogs approach him, and finally, having chosen a direction and realizing the danger, he laid his ears and rushed at full speed. He was lying on the stubble, but in front there were greenery, on which it was marshy. The two dogs of the suspicious hunter, who were the closest of all, were the first to look and pawn behind the hare; but they had not yet moved far towards him, when the Ilaginskaya red-spotted Yerza flew out from behind them, approached the dog at a distance, with terrible speed gave, aiming at the tail of the hare and thinking that she had grabbed him, rolled head over heels. The hare arched its back and pushed even harder. A broad-assed, black-spotted Milka came out from behind Yerza and quickly began to sing to the hare.
  - Honey! mother! - Nikolai's triumphant cry was heard. It seemed that Milka would now hit and pick up the hare, but she caught up and swept past. Rusak retired. The beautiful Yerza settled down again and hung over the very tail of the hare, as if trying on how not to make a mistake now, to grab her back thigh.
  - Erzanka! sister! I heard Ilagin crying, not his own voice. Erza did not heed his pleas. At the very moment when it was necessary to wait for her to grab the hare, he swung and rolled out to the border between greenery and stubble. Again Yerza and Milka, like a drawbar pair, leveled off and began to sing to the hare; at the turn it was easier for the hare, the dogs did not approach him so quickly.
  - Scold! Scold! Pure business march! - shouted at that time a new voice, and Rugay, the uncle's red, hunchbacked male, stretching and arching his back, caught up with the first two dogs, moved out from behind them, gave a terrible self-sacrifice already above the hare, knocked him off the line into the green, another time he slammed even more viciously across the dirty greenery, sinking up to his knees, and it was only visible how he rolled head over heels, soiling his back in the mud, with the hare. The star of dogs surrounded him. A minute later everyone was standing near the crowded dogs. One happy uncle of tears and otpazanchil. Shaking the hare so that the blood would flow, he looked around anxiously, running around with his eyes, not finding the position of his arms and legs, and he spoke, not knowing himself with whom and what.

New versions of K-Lite Mega Codec Pack no longer support Windows XP. If you need to download K-Lite Codec Pack for Windows XP, then use one of the links below:

What's new in version: List of changes

Regardless of the version of Windows, the problem is the same: to watch a movie, you need codecs that are not included in the operating system. Therefore, the package, on the one hand, needs no introduction: many users download it immediately after installing Windows in order to improve support for popular multimedia formats in one fell swoop.

On the other hand, rarely anyone bothers to study the contents of this package (the principle “if only everything works”) works, although there are reasons for this. So, K-Lite includes utilities that can be used to diagnose and solve particular problems associated with the operation of codecs.

In addition, the K-Lite package not only adds extensive support for media formats, but also allows you to fully control the processing process. At the installation stage, you can select the necessary components, as well as specify your preferred filters and decoders. The playback quality and processing speed depend on their correct settings.

All these points will be covered in this review.

Key Benefits of K-Lite Codec Pack

K-Lite Codec Pack has many strengths, we will limit ourselves to listing the key points:

Internal Component Compatibility

The K-Lite distribution is always tested for compatibility by experts. When installing codecs yourself, it's easy to come to the situation of "Codec hell" ("Hell of codecs"), since many filters do not get along with each other. To eliminate conflicts, you need to look for the cause of "evil" and use special utilities to remove one or another component.

Good compatibility with Windows

In addition to the aforementioned lack of conflicts, the package is easy to completely remove from the system without leaving a trace. During installation, K-Lite checks for other codecs in the system and suggests their use during installation, among other options. Also, at the installation stage, a search is made for faulty codecs and it is proposed to fix them.

Flexible setup

There are 5 package options available for download with different configurations, 3 installation modes and profiles are also offered.

For each multimedia format, you can choose the appropriate decoder from the available options, by default K-Lite selects the most optimal one. For Windows 7 and 8 users, a special Preferred Filter Tweaker for Windows 7 and 8 utility is provided to configure preferred codecs bypassing the OS.

Regular updates

The user does not need to keep track of the update of each audio or video codec or other components: K-Lite always contains the latest versions.

K-Lite Builds

There are 6 package options available on the download page:

• Basic - provides support for the most famous media formats: AVI, MKV, MP4, OGM, FLV. The minimum set that does not include a video player. It will be optimal if you prefer to use another player, and a minimum set of codecs is enough to play.
• Standard - also includes Media Player Classic HomeCinema, DVD MPEG-2 decoder (opens up more options when playing DVDs), MediaInfo Lite utility, which displays detailed information about the media file.
• Full - compared to the standard version, this includes madVR - a high-quality renderer, the GraphStudioNext diagnostic utility and additional DirectShow filters.
• Mega - contains ACM and VFW codecs, DirectShow filters, additional utilities. During installation, a video player will be offered to choose from: Media Player Classic HomeCinema or Media Player Classic Regular. You can read about the differences between them below.
• 64-bit build - recommended to install over the 32-bit version if you plan to play videos in a 64-bit environment. It is worth emphasizing that this package will be in addition to, and not in place of, the above options, since not all applications support 64-bit codecs.

There is another way to view build information, available on the K-Lite website in the form of comparison tables: and . In fact, if you are interested in a specific function or format, then you do not need to compare anything.

Installation

There are three possible installation modes - simple, normal and advanced, depending on which the number of settings for the components included in the package changes.

The next step is to select an installation profile. It affects not only the number of components, but also the preferred settings. For example, "LAV for everything" implies that video decoding will be done with LAV Video whenever possible. "Lot of stuff" - installation of the maximum number of components.

You will not be able to install multiple codecs or filters to play the same format, as this would inevitably cause a conflict. The "Use system default" option means that the installer has already detected a codec that does not belong to K-Lite: for example, included in the OS or installed earlier.

At the last step ("Hardware Acceleration") - hardware video acceleration settings. It is highly desirable to read a small reference document describing the settings (the "Help" button at the bottom of the window).

So, according to the help, we set the standard settings on a fast processor (“Use software decoding”), on NVIDIA video cards - CUVID or LAV DXVA2, on AMD - LAV DXVA2, when using Media Player Classic HomeCinema - DXVA decoder.

Composition of K-Lite

The codec pack includes:

• DirectShow splitters
• DirectShow video decoding filters
• DirectShow audio decoding filters
• DirectShow audio parsers
• directshow subtitle filter
• other codecs and filters
• Media Player Classic / HomeCinema and additional utilities

In order to “decipher” this list, it is necessary to clarify the meaning of some terms (see below). The work of the splitter, filters and parsers can be more clearly displayed by the GraphStudioNext program, which is part of K-Lite. For example, the easiest way to open any media file is with the command "File - Render Media File ...". The process of processing the file will be demonstrated in the diagram.

directshow is a framework from Microsoft that runs on Windows and is an environment for playing audio and video formats and input / output to devices. Some formats are supported by DirectShow natively, the list changes with each version of Windows. At the moment, DirectShow is being replaced by the Media Foundation framework, which is integrated into Windows 7 and Windows 8.

Splitters(English "source filters", literally - source filters) are separated from the container audio and video for further processing by decoders. It must be understood that a playback file is a container, which is often erroneously called a video format.

Decoding Filters DirectShow video and audio, or conversion filters, add support for additional file formats that can be played by any video player.

An example of filters is the popular ffdshow decoder, which works on the basis of open libraries. It allows you to play Xvid, DivX and H.264 - and these are probably the most cases that you have to deal with. ffdshow includes filters (not to be confused with DirectShow filters) that allow you to control playback in real time: apply filters, resize, change color, etc.

The developers of K-Lite directly advise to choose the LAV decoder due to its greater performance and stability, and ffdshow - only if extra functionality is needed.

Along with LAV Video, it is included in all packages, other filters are optional and can be replaced.

Similarly, audio filters decode audio formats separated from the container by a splitter. Among them is the popular AC3Filter library, which adds support for AC3 and DTS along with tools for setting up multichannel audio.

A task parser- signal output to the device after its decoding.

Media Player Classic

Of course, when installing K-Lite, almost any player (GOM Player, LightAlloy, Zoom Player, etc.) will work with the required formats. However, in the case of K-Lite, it is still preferable to use Media Player Classic, which is not included only in the Basic build. This video player is best optimized for this package, moreover, it is included in K-Lite in a modified form.

There are two players: Media Player Classic Home Cinema and Media Player Classic Regular, which is an offshoot of the Home Cinema project. Despite the fact that they are based on the same platform, there are differences.

Regarding the Classic Regular player, we can only say that, in comparison with Home Cinema, it is less functional. To get acquainted with it, you need to install the Mega assembly and during installation specify Media Player Classic Regular as your preferred player.

Among other nice additions Media Player Home Cinema: displaying images on multiple monitors, H.264 hardware decoding, support for many subtitle formats, the presence of localization, including Russian. The original Home Cinema distribution, which can be downloaded from , already provides decoders (so the player can work standalone without installing K-Lite). The description of K-Lite also states that the codecs built into the player have been replaced with more efficient ones - those that are available to choose from when installing K-Lite.

Utilities

After installing K-Lite, it becomes necessary to fine-tune the codecs. You can find auxiliary utilities in the directory with the installed K-Lite package, the Tools folder.

Codec Tweak Tool

The main settings of K-Lite are collected in the Codec Tweak Tool shell. In the settings, you can remove broken codecs and filters (that were installed incorrectly or left traces in the registry), re-register filters, reset settings to the original ones, generate a log from the contents of the package, sometimes this is required for diagnostics.

The most interesting section is “Configuration”, here are collected the settings of all installed filters (audio, video, source filters (splitters)). In principle, the same can be easily done through the parameters of the video player, but this would not be the most convenient way.

Codec and Filter Management allows you to activate and deactivate unnecessary filters and codecs, including those included in the OS. Additionally, by analogy with the K-Lite installation, you can specify your preferred splitters for each format.

Preferred Filter Tweaker for Windows 7 and 8

Windows 7 and Windows 8 users should pay attention to the Win7DSFilterTweaker utility. Its necessity is manifested in the fact that these operating systems have their own audio and video decoding system - Media Foundation. The built-in features of this framework cannot be blocked by third-party filters without making changes to the registry. For this, in fact, this utility is intended. With it, you can not only specify preferred decoders, but also disable unused ones, up to deactivating Media Foundation.

mediainfo

A utility with which you can find out detailed information about a file: bitrate, resolution, container, audio and video formats, compression. The technical data will be useful if you need to reconfigure filters or install a missing codec. This program is built into Media Player Classic and is available as the "Mediainfo" tab, "Properties" item in the context menu.

GraphStudioNext

A very informative utility for analyzing audio and media files. Once the content has been processed, GraphStudioNext shows in diagram form the processing that a file goes through before being displayed on the screen and speakers. It all depends on the specific configuration of the codecs in the package. Therefore, GraphStudioNext will be useful for diagnosing problems with file playback. In addition, each component in the diagram is clickable and opens the codec or splitter settings.

VobSubStrip

Editing subtitles in IDX format - you can remove unnecessary streams from the list and resave.
