Only title tag read/displayed on id3v2 tags in mp3 files accessed over upnp
VLC version 2.0.8 on Ubuntu 12.04 LTS; also VLC version 2.1.4 on Mac OSX 10.6.8 (tried VLC version 2.1.3 Win32 on 64-bit Windows 8.1, but upnp doesn't work at all (crashes when upnp category is clicked) on that version. This is a known, unfixed bug in the 2.1.x versions on windows (see ticket #9501 (closed))) Accessing a upnp server: PS3 Media Server v 1.90.1 running on Windows XP SP3.
When accessing MP3 files over a upnp connection, only the title tag is read from the ID3V2.3 tags. When viewed in the playlist or when clicking on Media Information... in the context menu, only the Title field is populated. No other field (album, artist, track number, etc) is populated, even though all that information is available in the tag.
And it is the title tag, not the filename, because my MP3 files have filenames that are different than the contents of the title tag, and I see the contents of the title tag. This problem applies whether or not the tag is encoded in UTF-16 or in ISO-8859-1. (Note that those 2 encodings are the only two ID3V2.3 specification-correct encodings. UTF-8 is not supported until ID3V2.4).
When the same MP3 file is accessed directly over a file share (samba mount on linux and mac osx) instead of upnp, all the ID3V2 tags show up correctly, on both versions of VLC listed above.
Other not-VLC upnp clients and renderers show all the ID3V2 tags correctly, such as my Playstation 3, and my networked home theater receiver.
As a different control. VorbisComments in FLAC files are shown correctly in VLC over both upnp and direct network file access, on both versions listed above.
