MediaInfo supplies technical and tag information about a video or audio file. MediaInfo supports various codecs (DivX, XviD, MSMPEG4, ASP, H.264, AVC, OGG, MP3, WAV, RA, AC3, DTS, AAC, M4A, AU, AIFF, SRT, SSA, ASS, SAMI...) and containers (MKV, OGM, AVI, DivX, WMV, QuickTime, Real, MPEG-1, MPEG-2, MPEG-4, VOB...).
 Why should you use it?
MediaInfo checks file extension and file content, and you can see, as soon as the headers are available (The first chunk of a file, usually), if a file is really a multimedia file or if it's some other file type, or just fake data.
There are several way to use it, one of them is to get it integrated into eMule.
 Integrating Mediainfo with eMule
To get it working with eMule and be able to see more information about the files you are downloading/sharing, you just need to download one of the archives here: http://sourceforge.net/project/showfiles.php?group_id=86862&package_id=90614
and extract the mediainfo.dll file into the same directory where the eMule.exe file exists.
The next time you start eMule, it employs the functions made available in the mediainfo DLL. eMule will then be able to detect more filetypes and codecs, and will be able to show additional information if available (like title, author, program used and such) in the in the file -> detail -> content tab.
If mediainfo is not available eMule will use it's own internal detection routines to detect codecs and tags. These internal routines are very limited, and they work only on specific types of files. Hence the reason why the mediainfo package is popular.
eMule prefers to use its own internal mediainfoanalyzer for avi RIFF files. To use the dll you will have to disable MEDIAINFO_RIFF in preferences.ini
 Versions working with eMule
- At the time of writing the current version of MediaInfo is 0.7.4.7 and works correctly with eMule 0.48a.
- Versions 0.7.0.3 is also a known working version.
- Version 0.7.10 can cause extreme usage of resources depending on the file type. See xtreme topic
 Capabilities of mediainfo over standard eMule
As an example of the power of mediainfo, here is a screenshot on how an mkv file with x264 video and ac3 audio is seen in this way WITHOUT mediainfo.dll:
and this screenshot shows how it's seen WITH mediainfo.dll:
 Many technical details still not shown
Mediainfo is capable to deliver far more data (technical data) compared to what eMule is able to show in the content tab (only tags?). We hope the capabilities of eMule (or others mods) will be extended with further improvements to Mediainfo ;)
 Known problems
Current version of mediainfo (0.7.4.7) is not capable to give useful information for mpeg files NOT YET COMPLETED.
It works for any other file, but not for INCOMPLETE .mpg /.mpeg. (For more informations about this specific problem see: https://sourceforge.net/tracker/?func=detail&atid=581181&aid=1749940&group_id=86862 )
So it's up to you to choose an old version (the suggested one distributed also with morphxt installer package is 0.7.0.3) not supporting MKV, X264 and others newers formats, or a new version (like 0.7.4.7) not able to print useful information about INCOMPLETE .mpg/.mpeg files :)
