Is there a way to abort long-running load/decode operations? about pyturbojpeg HOT 1 CLOSED

TL;DR: PyTurboJPEG is a wrapper for the TurboJPEG C-API of the libjpeg-turbo library, which does not support the jpeg_read_scanlines function call or a similar function to abort long-running load/decode operations.

A viable workaround is using Python's multiprocessing library or a similar approach to launch a worker process, and call the terminate() function if it exceeds a timeout value. https://docs.python.org/3/library/multiprocessing.html#multiprocessing.Process.terminate

The libjpeg-turbo library provides two C-APIs: the TurboJPEG C-API and the libjpeg C-API. The jpeg_read_scanlines function is only available in the conventional libjpeg C-API. Even the official TurboJPEG Java API doesn't provide this functionality. See details at libjpeg-turbo Documentation.

Since this is outside the scope of using the TurboJPEG C-API, I’m going to close this issue. Thank you for your understanding.
