Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

In both Windows and Linux, when the OCR module is present, the following options will cause a crash:
ccextractor-ocr -out=srt -parsePMT -parsePAT -codec dvbsub 01-BBC1.EastEnders.ts
(ccextractor-ocr is just the name of the binary in this case)
Valgrind shows this:
