Subject: libdvbv5: dvb-file: better handle format differences Author: Mauro Carvalho Chehab <[email protected]> Date: Sat Apr 11 12:54:25 2026 +0200 Legacy formats may not have all values for DVB-S2 and newer standards. Better handle errors during format conversion by replacing invalid values with AUTO, while still reporting warnings.
