Investigation so far (from Discord, for general reference):

---

OK, the beta4 iOS build ran green: https://github.com/jamulussoftware/jamulus/actions/runs/20899686885

Changes merged since are:

• 762529c Bump Windows to 6.10.1 (no iOS build done) (no iOS build done)
• 05a101d Add CONFIG+=add_ios_ffmpeg_libraries # QTBUG-129651 to iOS (no iOS build done)
• a4efd8c Updated docs for iOS manual build (no iOS build)
• cb5e436 SRV discovery
• b448184 Use regex match for autobuild branch name (no iOS build done)

So I'll try reverting 05a101d4: https://github.com/pljones/jamulus/actions/runs/21331858163
which fails (similarly - but not identically - to the rebuild below)
https://github.com/pljones/jamulus/actions/runs/21331858163/job/61397815889#step:10:788

Actually, easier and more accurate -- I've tagged that merge as autobuild-ios-ffmpeg and run an all targets autobuild: https://github.com/jamulussoftware/jamulus/actions/runs/21331960660
https://github.com/jamulussoftware/jamulus/actions/runs/21331960660/job/61398051529#step:10:412
https://github.com/jamulussoftware/jamulus/actions/runs/21331960660/job/61398051529#step:10:418

Hm. Doesn't look related?

Indeed, rerunning the autobuild for r3_12_0beta4 fails, pretty much the same: https://github.com/jamulussoftware/jamulus/actions/runs/21332039307/job/61398228552#step:10:793
