Description
the `ThumbnailImage` and `CoverArtImage` are implemented different on different platforms:
| platform | thumbnail | cover art | notes |
|---|---|---|---|
| win32 | PKEY_ThumbnailStream | - | no obvious "cover art" api |
| ffmpeg | AV_DISPOSITION_ATTACHED_PIC | - | AV_DISPOSITION_TIMED_THUMBNAILS unused |
| gstreamer | GST_TAG_PREVIEW_IMAGE | GST_TAG_IMAGE | semantics inverted to ffmpeg/win32 |
| darwin | not implemented (preparations for AVMetadataIdentifierID3MetadataAttachedPicture) | preparation for(AVMetadataCommonIdentifierArtwork, AVMetadataIdentifieriTunesMetadataCoverArt, AVMetadataIdentifierQuickTimeMetadataArtwork) |
actual image retrieval not implemented, semantics inverted to ffmpeg/win32 |
we should align the behaviour on all platforms.
