Marth64 f1abb754aa avformat/dvdvideodec: Fix incorrect padding cell trim logic 
When -trim option is used (by default), padding cells
at the beginning of the title are supposed to be ignored.
The current implementation does the ignoring after we
have locked on to the PGC navigation event stream,
but does not set the PGC/PG state properly.

This causes false positives and errors on some discs
due to a search for a program stream cell that
never succeeds. User would have to know to disable
the -trim option to work around the issue.

Simplify the logic and move it to the NAV packet
event handling, in turn implementing the behaviour
correctly and fixing the trim function for impacted discs.

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.
