The cause of the problem is as follows:ffformatcontext(s)->id3v2_meta is obtained after avformat_open_input processing. It is not the original data of s->metadata.

static int wav_read_header(AVFormatContext *s)：ff_id3v2_read_dict(pb, &ffformatcontext(s)->id3v2_meta, ID3v2_DEFAULT_MAGIC, &id3v2_extra_meta); I modified：ff_id3v2_read(s, ID3v2_DEFAULT_MAGIC, &id3v2_extra_meta, 0);
The displayed result is fixed，as follow：
