Not having many options left (and not having any more time left to mess with it), I decided to move to Qt5’s QImage, and reprogram all image manipulation code in libopenshot. I consider both of these issues show-stopping! Performance Issues - Certain image manipulation routines, such as rotation (a type of distortion), took a crazy amount of processing time (0.5 to 1.5 seconds per frame).There were a couple workarounds I came up with, but they were just as ugly.
The result was a really ugly deadlock, freezing the execution of the program. ImageMagick++, which is a C++ library for manipulating images, and deeply integrated with libopenshot, hit me with the following: Performance Improvements - Image ManipulationĪs everything started to really come together, and I was able to start testing more complex functionality from the UI, a really big, show-stopping type of issue was discovered.
