Thanks to SuslikV for pointing this out.

The default return value is present
...
Remove else so that the default return value is used if no other return was used."else if" in line 334 had no else and therefore in some cases no return value was present.

Improved Keyframe Performance ( #197 )
...
* Refactor of Coorindate and Keyframe optimized for performance (much faster than previously). Also refactored FrameMapper to not use a Keyframe, and to only process frame mapping when needed... speeding up Json loading of project files.
* Fixing FrameMapper linear calculation to match existing Keyframe calculation
* Fixing Keyframe to pass original unit tests, and correctly calculate the Keyframe repeat fractions and deltas.
* Small refactor of time mapped logic in Clip.cpp

Big update! Updating all "long int" frame number types to int64_t, so all 3 OSes will produce the same depth and precision on frame numbers. Also removing variable bitrate support temporarily, since it causes more problems than it solves.

Updating references to frame number / position to long int, there were still quite a few old "int" declarations, which limits the length of frame number. Also, updated precision of KeyFrames to use double (instead of float) for higher precision, which fixed lots of issues with very long videos (since our FrameMapper used a KeyFrame object to create a map to new frames)

Huge refactor of keyframe point handles (bezier quadratic curves) to use CSS-style syntax. Basically, the left and right handles of a point now use percentages, such as 0.0, 1.0, 0.5, 1.0 (between 0 and 1), and become real coordinates based on the value differences between points (in real time). Also simplified the JSON property creation. Also, many unit tests have been updated, because they were actually generating the incorrect values from before... although only slightly in most cases. Now they have correct values from the default bezier handles.

Improved image caching logic, to better estimate max image sizes possible, based on clip scale and keyframe settings... so we are always dealing with the smallest possible frame sizes for performance (without losing quality)

Fix compilation ambiguity for system jsoncpp
...
In upstream JsonCpp there are two [] operators for Json::Value - one taking unsigned int, second taking int - passing long int leads to ambiguity.

Fixed bug in RemovePoint, and improved the AddPoint KeyFrame method to remove a previous, duplicate point (based on co.X value).

Added dropdown choices into JSON properties, so a UI can correctly list the options for certain properties. Fixed a bug when deleting all Points from a Keyframe, and added some missing Enums from the Python/Ruby bindings.

Improved support for missing frames and invalid PTS (which result in gaps and duplicate frames). Also changed frame number to larger data type, and did some code clean-up and refactoring. Less crashes, and more video support!

Replaced ImagMagick with QImage on almost all key methods and classes. Reprogrammed all effects and the entire rendering pipeline to use QImage and QTransforms, primarily for increases in speed and stability. libopenshot is more than 10X faster on many of the most CPU heavy tasks. This was a huge change, and still has a few minor issues relating to BlackMagick Decklink and Text rendering.... which should be resolved very soon.
...
Also, much work has been done on memory management / leak detection, and optimizations with multi-threading... including a new thread cacher class used by the video playback (which is smoother than ever).
