Show a preview video on MacOS

[Aces-and-Jacks]

What you want IINA to do:
I want IINA to show a preview of a video the same way quick player does

What IINA does currently:
Shows the file preview instead of a video preview

Why you think this should be added:
So if I want to view it with out opening the application I can. Similar to how you can preview photos and videos by pressing space bar with them selected

Examples of other projects that have something similar:

I wasn't sure what to search for so sorry if it's a duplicate. I wasn't sure if this was possible so if it isn't or if it's incredibly hard to do than I'm sorry for wasting your time.

The Apple term for this is Quick Look.

Took me a while to find the existing open issues regarding this functionality. They are issues #146 and #3816. There is also PR #1941 from a long time ago.

The Apple QuickLook Framework does allow apps to provide extensions for previewing files. However as indicated here the framework requires use of AVPlayer for playing media. That restriction prevents IINA from playing media.

Given that restriction, I don't see how IINA could do a better job than the existing excellent open source package: QuickLook Video

I'm going to close this issue as a duplicate. Don't worry about not finding the existing open issues and entering a duplicate. Happens. Not a problem. I appreciate the nice clear report.

@low-batt Does the open source package: quicklook video do the same as IINA? Or do they work together?

[low-batt]

QuickLook Video is not tied to IINA in any way except this:

• IINA can play media that macOS / QuickTime Player does not support
• QuickLook Video can provide thumbnails for media that macOS / QuickTime Player does not support

So they work together to provide support for media types that Apple does not support. What is lacking over what you get with media types Apple supports is features such as playing a movie directly in the icon displayed by Finder.

Thank you for your help

See issue #146 for some additional discussion regarding this potential feature, including possibly being able to play videos without using AVPlayer.
