avformat/mov: Avoid overflow in dts 
This basically ignores the overflow without undefined behavior, alternatively we could detect and error out

Fixes: signed integer overflow: 6310596683470275584 + 7660622966157213696 cannot be represented in type 'long'
Fixes: 70433/clusterfuzz-testcase-minimized-ffmpeg_IO_DEMUXER_fuzzer-5483347233538048
Fixes: 369662284/clusterfuzz-testcase-minimized-media_metadata_parser_fuzzer-5327368763670528

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.
