Quicklook - how to add file formats like MKV or FLV

Why don't you post a question on that url you supplied.

This really isn't a Quicktime question.

hy i tried your instructions and didnt work
im probably doing something wrong
can u give me the rookie version of how to get mkv playing in quicktime
thnx

The only way to play .mkv file in QT is to install this plug-in.

http://perian.org/

i already have perian installed and can play mkv fine in quicktime.
sorry my bad. what i meant was how can i play mkv in QuickLook.
i have looked at the tutorial but i dont know whick plist to edit in text edit.
VLC plays all my mkv files by default. so should i edit that info.plist.
if i want QT to play an mkv i have to select "open with" then "other" and select Quicktime from the apps list.
so do i need to make QT my default mkv player then edit its info.plist.
if so how do i do this

which .plist do i edit in the resources folder
i have action.plist dotmac.plist etc etc
i dont see any info.plist in the resources folder
i ctrl+clicked and "show package contents" on QT
this opens a window
i click into contents folder
in this there is _coderesources, framework, info.plist, macOs, pkginfo, plugins, resources, version.plist_
i clicked in the folder "resources"
no info.plist in here.
what do i edit ???

theres no need to be smart about it.
how did i answer it if you said go to the resource folder
*did you actually mean the content folder*
if you did, then did you not see my previous post in which i stated that i already followed the instructions to change the info.plist file in the contents folder
i changed the quicktime info.plist and restarted my computer and still no mkv in quicklook
*all i want to know is if im doing something wrong and how to rectify it*
in the QT info.plist the "</dict></plist>" in at the very bottom of it
so then i pasted in
"<key>UTExportedTypeDeclarations</key>
<array>
<dict>
<key>UTTypeConformsTo</key>
<array>
<string>public.movie</string>
</array>
<key>UTTypeDescription</key>
<string>Matroska Video File</string>
<key>UTTypeIconName</key>
<string>generic</string>
<key>UTTypeIdentifier</key>
<string>com.apple.quicktime.mkv</string>
<key>UTTypeReferenceURL</key>
<string> http://www.matroska.org/</string>
<key>UTTypeTagSpecification</key>
<dict>
<key>public.filename-extension</key>
<array>
<string>mkv</string>
</array>
</dict>
</dict>
</array> "
then _closed textedit and choose save_
then _restarted computer_
tried an .mp4 first in quicklook and it worked fine
tried .mkv and still not working

i also tried that, i pasted it in info.plist saved changes, restarted and nothing changed, i have perian.component in library/quicktime, i can watch all mkv files in quicktime, but those files have no preview and cannot quicklook, anybody please help....

I think I have your solution. Make sure you're putting all that code just BEFORE </dict>
</plist>

so basically you scroll to the end of the info.plist file and then paste everything before those two lines. Then logout and login or reboot and it should work after that point.

thnx gizmo8599. i finally got it. it didnt work at first when i tried what you said.
so after i restarted computer and mkv didnt work in quicklook i went to my applications folder and moved the Quicktime file out of there . then moved it back in. opened quicktime. quit QT. then back to my mkv file and it worked in Quicklook.

Please help. I've done what's been discribed and it didn't work. It would be nice if I could get it to work!
