Access
RTP PCR handling
We synthetize PCR everywhere, but here it supposely "Does not make sense" !4686 (merged) "If we need to support"
- No set_pcr in access
Qt
Qt6 is nigh (!4783 (merged)), some details need to be agreed:
- Windows 7 status: keep win7, it's fine to only use openGL on win7
- restricting windows build on Qt LTS (6.5) or using up-to-date Qt version (easier for dcomp integration)
- use the last preferred version on Windows, we don't care about linux (distrib jobs)
- Ubuntu LTS ships 6.2.4, we need 6.2.5 for .pc files, be sure that dev won't complain.
- Possible workaround, use qmake. Ubuntu should release a patch release soon that should include Qt 6.2.5 since it was released in 2023 Summer.
