An Appcelerator Titanium module for iOS to create animated GIFs from videos based on NSRare/NSGIF with modifications and memory leak fixes on my fork https://github.com/kosso/NSGIF.
See the full test app (TiNSGIFTest) in the examples folder.
This module was built against Titanium SDK v.4.1.1.v20150802200935. To build it yourself you might need to edit the manifest file and titanium.xcconfig to suit your local Titanium installation locations.
