[ Impact ]
openshot is completely unusable as it will fail to start with the following error:
Traceback (most recent call last):
File "/usr/bin/openshot-qt", line 33, in <module>
sys.exit(load_entry_point('openshot-qt==2.5.1', 'gui_scripts', 'openshot-qt')())

self.cache_renderer.setInterval(0.5 * 1000)

version:INFO Found current version: {"error_rate_stable": 0.25, "trans_rate_stable": 0.01, "error_rate_unstable": 0.05, "openshot_version": "3.1.1", "trans_rate_unstable": 0.001}
[ Test Plan ]
Simple test:
* Execute openshot-qt, which will fail to start if its not fixed.
* With the fixed package, openshot-qt will start and the tutorial will show.
Detailed test:
* Import few videos or images
* right click on the thumbnail
* Click on "Add to timeline"
* the image or the video should now be added to the timeline
* add few such images and videos
* Try playing the timeline
[ Where problems could occur ]
The problem was caused because float is used as some of the arguments where int is now expected. There can be some more such parts in the code which I might have missed during my testing. And if any such code is executed with a float argument then the application might again crash.
[ Other Info ]
* As mentioned in the patch, part of the patch is from upstream. Similar changes have been done in few more places which I found during testing.
