GNOME Bugzilla – Bug 752475
tracker-extract-vorbis, -flac: embedded media art (METADATA_BLOCK_PICTURE) not supported
Last modified: 2021-05-26 22:26:05 UTC
tracker-extract-mp3 knows how to extract ID3v2 APIC frames from MP3 files and feed them into libmediaart. However, tracker-extract-vorbis does not know how to process the recommended METADATA_BLOCK_PICTURE tag in Vorbis comments (which is a Base64-encoded Flac METADATA_BLOCK_PICTURE structure): https://wiki.xiph.org/VorbisComment#METADATA_BLOCK_PICTURE tracker-extract-flac doesn't seem to have any support for libmediaart at all, and in particular no support for the embedded binary METADATA_BLOCK_PICTURE structure.
Created attachment 339263 [details] [review] Album art for the flac extractor Here's the code from Vorbis ported over. It seems to work for me up until the libalbumart code, but stops there. It seems to be sending good data, but nothing shows up in the libalbumart cache.
FLAC extraction fixed, and included in the patch in #774694 instead.
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version, then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new enhancement request ticket at https://gitlab.gnome.org/GNOME/tracker/-/issues/ Thank you for your understanding and your help.
