Michael Trebilcock created this originally for OS4 - his archive is here - YouTube_URL_Extractor - currently for OS4 at v2.5, last updated December 2023 and it was converted from a prior release by Thomas Igracki for MorphOS from Michael's efforts as version 2.2, which seems to be the current one available from MorphOS-Storage.

Where you have v2.4 from for this utility I do not know?

So, we seem to be a few updates behind the OS4 version currently. Michael Trebilcock, who seems to be a busy guy for OS4, as he has quite a few programs assigned to his profile. If you contact OS4 depot they should have contact details for him - they are just not in the archive or the readme, likely so he does not get pestered by 'bots', etc..

Not sure if Thomas Igracki is still in contact with Michael Trebilcock, but if we are talking about a more up-to-date version based on Michael's current version then Thomas is probably the best person on M-Zone to PM or email to ask about any update/fix being possible for MorphOS.
