#6949: No support for multiple values in ID3v2.4 tags. -------------------------------------+------------------------------------- Reporter: | Type: defect escapereality | Priority: normal Status: new | Version: Component: | unspecified undetermined | Blocked By: Keywords: ID3 FFprobe | Reproduced by developer: 0 libavformat | Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Altough ''FFmpeg'' states that it has support for ID3v2.4 tags, there is one thing I can't get to work properly. The [http://id3.org/id3v2.4.0-frames ID3v2.4 specifications] state the following: ''There may only be one text information frame of its kind in an tag. All text information frames supports multiple strings, stored as a null separated list, where null is represented by the termination code for the character encoding.'' When I separate the values in a tag with NULL-characters, the values should all be recognized (following the ID3v2.4 specs). However, when I use ''FFprobe'', it only shows the first value. For example [http://mutagen.readthedocs.io/en/latest/man/mid3v2.html mid3v2] shows the tags correctly. [[BR]] Below is (a snippet of) the output of both ''mid3v2'' and ''FFprobe'' with an example file. The '''TCON''' (genre) and '''TPE1''' (artist) contain multiple values.
