Andreas Rheinhardt e1f41b4fdc avformat/wavdec: Fix reading files with id3v2 apic before fmt tag 
Up until now the cover images will get the stream index 0 in this case,
violating the hardcoded assumption that this is the index of the audio
stream. Fix this by creating the audio stream first; this is also in
line with the expectations of ff_pcm_read_seek() and
ff_spdif_read_packet(). It also simplifies the code to parse the fmt and
xma2 tags.

Fixes #8540; regression since f5aad350d3.

  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of 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.
