Marth64 4dc204ea3e avformat/dvdvideodec: Fix duration logic with 1 chapter and validate chapter range 
Chapters and duration are calculated together in dvdvideo demuxer.
Previous chapter calculation logic treated extraction of 1 chapter
using chapter_start and chapter_end switches incorrectly, returning
the duration of the entire title instead of just the segment.

Fix the logic so that it calculates and returns the duration of the
chapter segment instead. Additionally, validate that chapter_end
exceeds chapter_start (except in the special case of 0).

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
