MMP: Minimalist Media Player

An all-in-one media player, image library manager (with built-in image & thumbnail browser, and image manipulation), and timeline editor for fast lossless editing of audio and video files.

Good or bad, what do you like or dislike about MMP? Love it, or not what you were looking for? Let me know here. I'm very keen to hear from you. What additional features would you like to see in MMP?

Note that openImage=browser and exitBrowser=exitApp are the recommended settings. After running mmp-install.bat to register all the file extensions that MMP supports, this will allow you to take full advantage of the image library management controls in the Image & Thumbnail Browser by operating MMP as [in effect] two applications in one: the main media window for playing (and editing) audio and video files, and the Image & Thumbnail Browser for managing your image library.

• Ctrl-[H] to open the Help Panel(s) in both the Main Media Window and in the Image & Thumbnail Browser, listing all the many controls for audio, video, and images.

• Shift-[\] to open the MMP config window - contains explanations of all the options.

• Ctrl-[E] from the Main Media Window to open the Audio & Video Timeline Editor for fast, lossless editing of audio and video files.

MMP: Minimalist Media Player

A powerful and very effective media player built on MPV's API, libMPV-2.dll, which is, in turn, based on the famous FFMPEG.

MMP: Minimalist Media Player provides a minimalist keyboard- and mouse-operated user interface (with nearly 200 functions). Minimal on-screen clutter allows videos to be viewed without distractions. There are no window borders and no window title bar/caption, and keyboard options allow you to also have no progress bar and no audio/video timestamp, if that's what you want.

The window resizes to fit the video perfectly, eliminating ugly black borders/bands around the video, particularly above and below. All of this provides an immersive viewing experience even when played in window mode rather than full-screen. Despite all this, MMP: Minimalist Media Playerprovides a wealth of functions via the keyboard and mouse for manipulating the user-interface and the media files themselves.

This is a complete rewrite of (and supercedes) an earlier project which was based on Windows Media Player. As such, this incarnation of MMP: Minimalist Media Player provides far superior media file handling and playback functionality such as zoom, pan, step frame (forwards and backwards!), rotation, brightness control, playback speed, etc. Ctrl-[H] both in the Main Media Window and in the Image & Thumbnail Browser to view the Help panel listing all the many controls for audio, video, and images.

Media File Formats

MMP: Minimalist Media Player uses MPV/FFMPEG for its media playback and manipulation functions and will therefore play the overwhelming majority of media files (audio/video/image).

WIKI

MMP: Minimalist Media Player now has its own domain and its own wiki which is constantly being added to. Feel free to request additional clarification on any aspect of MMP and the Wiki will be updated accordingly.

Keyboard Controls

A brief description for each of the keyboard controls follows below. Note that it contains all of the controls in the Main Media Window but not necessarily every control that is available in the Image & Thumbnail Browser. The Ctrl-[H] Help panel for each window will give a concise list of what's available. For an even quicker grasp of what keyboard controls are available to you and of MMP's capabilities, a quick look through the keyboard actions listed in view.mmpKeyboardMain.pas and in view.mmpKeyboardThumbs.pas will tell you what actions you can take in the Main Media Window and in the Image & Thumbnail Browser, respectively.

(For a quick run-down of the options in the MinimalistMediaPlayer.conf file, see the wiki page)

Note that openImage=browser and exitBrowser=exitApp are the recommended settings to the get the most out of MMP's capabilities.

Significant Releases

MMP (v5.1.0) Shuffle Mode added, and a combined Audio & Video playlist filter for when your music folder contains a mixture of audio files and music videos

MMP (v5.0.0) Keyframes for video editing: You can now use keyframes to accurately determine where to start segments so that your exported segments even more closely match your desired start point and length

MMP (v4.3.0) Added a config dialog (Shift-[\]) to explain and configure all the settings in the MinimalistMediaPlayer.conf file

MMP (v4.0.6) Added support for .jxl and .vtx image formats, in addition to .jpg, .jpeg, .bmp, .png, .webp, and animated .gif, .avif, .jfif

MMP (v4.0.2) Ctrl-Shift [C] will clean-up your leftover audio and video editing files in the current playlist folder.

MMP (v4.0.1) Now with multiple delete methods (recycle, delete or shred) and playlist filtering to automatically play through only the images, audio or video on an entire drive.

MMP (v3.0.3) can now play through all the media files on an entire drive, starting wherever you choose. Folders that don't contain supported media files will be skipped. For those folders that do, a new playlist will be created and played through automatically. You can, of course, have the [P]laylist panel open while you do this and watch MMP create each new playlist as it navigates through all your folders. You can use any of the playlist controls or double-click with the mouse to skip items in the list and jump to others. Requires the new nextFolderOnEnd=yes setting. See the release notes.

MMP (v3.0.0) added image and thumbnail browsing and image manipulation (e.g. brightness, contrast, gamma, saturation, rotate, crop).

MMP (v2.0.0) added fast, lossless audio/video editing: https://github.com/BazzaCuda/MinimalistMediaPlayerX/wiki/Lossless-Audio-Video-editing

TIPS

• You can crop an image (or video frame) by using zoom ([I]n/[O]ut) and pan (Ctrl-left, Ctrl-right, Ctrl-up, Ctrl-down) until the video window shows only the part of the image you want, then [F5] screenshot it. The screenshot will include any changes you've made to the Brightness, Contrast, Gamma, Saturation or Rotation of the original image.

• If you take a high resolution screenshot of a video or an image, the dimensions that the resulting image will have in the saved .png file can be set by first resizing the window to your required dimensions. The Image & Thumbnail Browser in particular gives you pixel-perfect control of the window dimensions.

• You can edit (Ctrl-[E]) an entire audio or video file using just [I] and [O] to set [I]n and [O]ut points. E.g. Use the [TAB] key to fast forward through a video and Ctrl-[TAB] to back up: when you get to the next section you want to include, press [I]; when you get to the next section that you want to exclude, press [O]. You don't even have to pause the playback. When you're done, click Export. It really doesn't get much easier than that!!

Key Features

---

• Automatically matches the aspect ratio of the window to the aspect ratio of the video so it fits the window perfectly, but still allows you to zoom and pan. This is something the MPV player itself doesn't do - you can only have one or the other. So no ugly borders. Ever. Unless they're hard-baked into the video, of course.

• Opening a media file from Windows Explorer (etc.) will automatically fill the playlist with all media files in the same folder. The playlist is sorted in "natural order" to match the order your files are [usually] listed in your file manager, taking numeric digits in filenames into account.

• You can "fast forward" through an entire media file by holding down the [TAB] key. Or backwards by holding down Ctrl-[TAB]. Thanks to MPV, the audio is maintained at the correct pitch.

• With [Numlock] On, several MMP windows can be controlled simultaneously, using various keyboard commands. This can be useful for, for example, comparing multiple copies of a movie to compare resolution quality. Ctrl-[9] will automatically arrange up to four MMP video windows so they fit correctly on your desktop. [V] will sync all the [V]ideos to the same timestamp.

• If a corresponding subtitle file exists for the media file (.srt file, for example), or if the media file contains subtitles, the subtitles will be shown automatically. [F7] will cycle through all the subtitle tracks in the media file.

• Full-resolution screenshots can be saved for individual frames and for a displayed image. Adjusting the size of either the Main Media Window or the Image & Thumbnail Browser will set the pixel dimensions of the saved image.

• All the keyboard and mouse functions are listed in a handy help panel which can be shown or hidden by pressing Ctrl-[H]. The full functionality of MMP: Minimalist Media Player can be used while this panel is showing so you can try things out.

• MMP: Minimalist Media Player provides handy keyboard access to brightness, contrast, gamma, saturation, rotation and zoom in/out. Handy tip: quite often, if you want to brighten the picture, increasing the gamma setting (and sometimes the contrast) gives better results than going straight to the brightness control.

• You can quickly [5] bookmark the current position of a media file and [6] restart from that point at a later time.

• You can quickly resize the video by holding down the [G] key to enlarge it. Or quickly reduce it by holding down Ctrl-[G].

• MMP: Minimalist Media Player provides full zoom and pan functions as well as video rotation.

• MPV playback can be configured via the normal mpv.conf file. As always with this file, some experimentation will be required to get the effect you require.

• N.B. Many keys can be held down for rapid repitition.

The following list may be missing some of the very latest - see the Wiki for an up to date and detailed description of all of MMP's many controls and features, for both the Main Media Window and the Image & Thumbnail Browser.

Keyboard Controls (Main Media Window*)

---

* For the additional controls available in the Image & Thumbnail Browser see the Ctrl-[H] help panel in MMP's image browser.

Although there are a lot of keyboard controls, the alphabetic letters have been applied intuitively. The action description will therefore help to associate the action with the letter.

Many of these controls also apply to the Image & Thumbnail Browser. However, in some cases, the Image & Thumbnail Browser uses a different key for the action described below than what the Main Media Window uses //(e.g Ctrl-[S] vs [F5] for screenshots)//. Also, the Image & Thumbnail Browser has additional key controls specific to managing your image library which are not available in the Main Media Window. Refer to the Ctrl-[H] Help Panel in both the Main Media Window and in the Image & Thumbnail Browser if you're unsure. In both cases, the Help Panel can be left open while you use the full functionality of MMP, in order to help you learn the many controls available to you.

Dependencies

1. MMP: Minimalist Media Player requires libmpv-2.dll (MPV as a library) to be in the same folder as the executable. If you have an mpv.conf file in the same folder, MPV will take it into account when initializing, for example to specify your audio output preferences

2. Massive credit and thanks are due to Edward Guo for his excellent port of the MPV API (libmpv) to Delphi, https://github.com/nbuyer/libmpvdelphi

3. The VCL component in MarkdownHelpViewer (https://github.com/EtheaDev/MarkdownHelpViewer) allowed the original RTF help file to be replaced with much more convenient and flexible .md markdown resources

4. Acknowledgement is due to the author of Perpetual Notes v4.05 (https://www.enselsoftware.com/product/PerpetualNotes.html) for being the only RTF editor I could find on the entire internet that could actually [,accurately] read back in what it had written out! (And I tested some big players during my search!)

5. Uses FastMM5 (https://github.com/pleriche/FastMM5). For full debug mode: 1) create an MMP_CHECK=MMP_CHECK environment variable and, 2) include FastMM_FullDebugMode64.dll in the executable's folder

6. Uses BazDebugWindow (https://github.com/BazzaCuda/BazDebugWindow) for writing debug messages to a separate window, rather than having lots of "ShowMessage" calls which interrupt the operation of the application. This is a reworking of the original GExperts DebugWindow. If desired, applications can be distributed with the debug messsages intact and as long as a user doesn't have the BazDebugWindow.exe installed, the calls do nothing

7. Uses JCL (https://github.com/project-jedi/jcl) (jclDebug.pas) to populate the stackTrace string in Delphi exceptions (mmpStackTrace.pas), reported in mmpExceptionHandler.pas

8. Uses MediaInfo (https://mediaarea.net/en/MediaInfo) to rapidly extract vital characteristics from any media file (dimensions, duration, chapters, etc). MMP: Minimalist Media Player requires MediaInfo.dll to be in the same folder as the executable

9. Uses FFMPEG.exe (https://ffmpeg.org/) to rapidly extract segments from an audio or video file and then stitch them together to create a new audio or video file, lossless and without re-encoding (i.e. copy/paste)

10. Uses FFPROBE.exe (https://ffmpeg.org) to obtain the timestamps of all the keyframes in a video. This allows for greater precision (and more accurate cuts) when deciding where to start a new segment during video editing

11. Uses the 64-bit versions of libeay32.dll and ssleay32.dll from the Open SSL Shared Library (https://openssl.org) to obtain a secure internet connection to GitHub to check for and download the latest release. MMP: Minimalist Media Player requires both DLLs to be in the same folder as the executable
