From 4a03e95ff4c3ed15d5420bd97c7868e0b62e1d0a Mon Sep 17 00:00:00 2001 From: Marth64 Date: Mon, 7 Oct 2024 18:04:59 -0500 Subject: [PATCH] avformat/dvdvideodec: default menu_vts option to 1 and clarify description Menu 0 is the VIDEO_TS root menu, which does not appear to be used commonly for menu segments. Instead, default to the menu of VTS 1.
