Revert "lavf/id3v2dec: support multiple values and TIPL frames"
see: Re: [FFmpeg-devel] [PATCH 2/2] avformat/id3v2: Check that decode_str() did advance

but in short, first our API since 16years says we dont have multiple values per key
(which it supports since 9 years only)

and it causes some problems for ffprobe apparently.
I do believe the original patch is the correct direction but it requires
more changes. So revert this until other things are in place and until
we have a consensus.

This reverts commit 80b77e8e8d.

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.
