The UI froze when converting too many files, because it updated each ones progress even though it remained the same for most files (0.0 or 1.0 when done). This was quite expensive. The change in
converter.py
is only for cosmetic reasons mostly as it didn't seem to have a large impact. Furthermore, pipelines are properly cleaned after conversion because at some point soundconverter crashed because of too many open files.I obviously should have done a stresstest earlier.
Also added an integration test for cancelling pipelines.
