MMP: Minimalist Media Player

NEW FUNCTIONALITY

• When exporting an edited video in the Timeline Editor, FFmpeg might report an error when extracting one or more segments of the video file

• Clicking the Rerun button will display something similar to this [contrived example]:

• The error messages often mention problems with stream mapping, e.g. “Stream map ' ' matches no streams” (see the first line of red text, above)
• although FFmpeg error messages can seem daunting, the solution to this one, and several others, is to simply have FFmpeg make its own copy of the video file
• when doing so, FFmpeg reads and rewrites all the streams it finds. This can often correct problems caused by some video-creation software

Making an MMP / FFmpeg-compatible copy of the video file has now been automated

• with the Ctrl-[E] Timeline Editor open, hold down Ctrl-Shift and move the mouse over the Export button
• the Export button will change to Copy

• when you click Copy, MMP will make a copy of both the media file and its corresponding .mmp file
• it will also make a copy of any keyframe .key file

• the copy operation will be as quick as if you were to copy the file yourself
• the file name of the copy will match the original with the addition of [c], e.g. “myvideo [c].mp4”
• a Console window will open showing you the progress of the FFmpeg copy operation

• for large video files (the example above is a 9GB file which took ~20 seconds to copy), the most useful information is the time=hh:mm:ss.ms timestamp on the last line which will show where FFmpeg has got to
• you can cancel the copy operation by clicking the Cancel button or by closing this Console window
• the copy will be loaded into the current playlist and will be loaded into the Timeline Editor
• the file will be positioned at the correct timestamp
• if the [audio or] video file was playing during the copy operation, the copy will continue playing at the exact point at which the copy operation completed, otherwise playback will be paused
• although not guaranteed, for many common FFmpeg problems with video files, when you click Export now, it often results in a successful export of your edited video

FIXES

• in most media files, stream IDs tend to correlate with the stream indices. Occasionally, this isn't the case. Either way, MMP should only use stream IDs for display purposes in the Segments & Streams panel, and only use stream indices in FFmpeg parameters. This is now the case

ASSETS

• this release includes new versions of ffmpeg.exe, ffprobe.exe, MediaInfo.dll and libmpv-2.dll (MPV as a library)
• you will need to update these manually: Auto Update will only update MinimalistMediaPlayer.exe
• you are advised to make backup copies of your existing files before overwriting them

KNOWN ISSUES

There are currently no known issues. If you experience one, please create a New Issue at https://github.com/BazzaCuda/MinimalistMediaPlayerX/issues and it will be investigated immediately

A Note About MPV Playback
MMP: Minimalist Media Player uses MPV as a library (aka the libmpv-2.dll file) to perform all the playback of audio and video files and to display images.
If you have any playback issues, especially with video files, it may help to download a different copy of libmpv-2.dll from https://github.com/shinchiro/mpv-winbuild-cmake/releases/.
You should download any mpv-dev-x86_64-v3……7z file. -dev- is the keyword to look for in the file name.
If you have a particularly old processor then ignore the v3 files and download any other mpv-dev-x86_64……7z file instead.

Keyframes

• The wiki article on keyframes is now available at Video Keyframes
• There is also an example editing session at Video Editing Example showing how to use the new keyframes functionality to achieve clean edits, with video clips showing the difference that using keyframes can make
• Ctrl-[W] in MMP will quickly take you to the wiki

Quick Install
The quickest way to get up and running with MMP is to

• unzip the .zip file to any folder, e.g. C:\MMP\
• run the mmp-install.bat file which will register all the file extensions that MMP supports*
• double-click any media file (audio, video, image) in your File Explorer software

* mmp-uninstall.bat unregisters them

Any issues, please let me know Issues

Wiki site
The fully-detailed wiki at minimalistmediaplayer.com continues to grow. The Wiki greatly expands on the brevity of the Ctrl [H] help panels by providing comprehensive info to help you get the most out of using all of MMP's many controls and configurable options

If there is a particular aspect of MMP that you would like more information about, let me know and I will add a topic to the Wiki or enhance an existing topic

Feedback

Asset files
The “…full.zip” release file below contains everything you need to run MMP: Minimalist Media Player:

N.B. Only MinimalistMediaPlayer.exe will be updated automatically. If the zip file contains newer versions of the other files, you should update and test these for yourself to ensure they will run on your Windows system. MMP will not make that assumption and overwrite your working versions. You are advised to make a copy of the older versions in case you need to revert to them.
