startAt and stopAt parameters not honored #85

Closed owencking closed 8 months ago

owencking commented 8 months ago

Bug Description

When values for startAt and stopAt are passed to the SWT app, those values should define the time range of annotated timepoints. As of now, at least in v4.1, these values seem to be ignored.

If you run the app with values for these parameters, the app will nevertheless process the entire video and produce annotations across the entire duration.

Reproduction steps

Specify startAt and/or stopAt parameters via a query string to SWT running as a web service, as with this query string: startAt=1237500&stopAt=1767000. SWT still begins annotating at 0ms and continues to 1784500ms.

The asset used during testing: cpb-aacip-37-95w6mnpw

Did a post-mortem on this because I knew that this error did not happen when I added the parameters. Turns out that _export_parameters(), an essential method for this, was removed after version v4.0. This somehow went unnoticed.
