 I would like to use ffmpeg / ffprobe to tag and dump my audio book
 metadata.

 Unfortunately the very important tags for audio book series

 - MovementName (MVNM for id3v2, ©mvn for mov)
 - MovementIndex (MVIN for id3v2, ©mvi for mov)

 are neither shown nor can be set. It would be a great improvement to have
 support for these.

 Links to the relevant source-code:
 - https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/id3v2.c
 - https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/mov.c#L310

 Thank you.
