Gyan Doshi 6941788d24 avformat/movenc: correct loci parameter handling 
3GPP TS 26.244 Table 8.10 specifies that longitude is written before
latitude. The MOV demuxer already expects the correct order. So, write
them in that order.

However, the user supplied string may also be used in MOV mode which
requires ISO 6709 format which specifies latitude first. The demuxer
also exports the loci value in that format. So parser adjusted as well.

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.
