A mac based player for Lottie

lottie-player's Issues

Associate .lottie files to open with lottie-player

Problem

On a Desktop operating system such as macOS it would be convenient if Lottie files would have their own dedicated file suffix such as .lottie which is unambiguously associated with them.

Lottie files are JSON files technically. So the file suffix .json is correct. But the downside is:

• You cannot identify a lottie file merely from glancing at the file name and it's suffix.
• You cannot associate that particular JSON file to open with a particular handler application.

Proposal

• Associate .lottie files with lottie-player, by adding the .lottie suffix to the CFBundleTypeExtensionsarray in the Info.plist of Mac app. Thus any .lottie file opened on macOS will automatically launch with lottie-player.
• If it's a plain text file validating as JSON, then open as-is.
• If it's the binary dotLottie file format (see #2 ), then open it according to the binary standard.

Support for .lottie files (ZIP archive with manifest + JSON animation + assets)

https://dotlottie.io has the format specification, the introduction reads:

dotLottie is an open-source file format that aggregates one or more Lottie files and their associated resources into a single file. They are ZIP archives compressed with the Deflate compression method and carry the file extension of ".lottie".

Could lottie-player support this file format?

Software bug

-Hello, I need this application, I work a lot with Lottie files and this application can help me a lot,
I installed the application and tried to open animation, but you can not see the animation playing (but see the timeline moving)
Unfortunately I still do not know how to program for Mac, can anyone fix it?
