These values are queried from the picture when trying to restore the base64 value, and in the case of my example picture, the depth value is not matching (24 in the original METADATA_BLOCK_PICTURE, 32 from the JPEG data). The problem is that not all original information is stored: Width, height, depth and number of colors are stored in the METADATA_BLOCK_PICTURE frame, but not in Kid3. To restore the key, the picture data is base64 encoded. my) fault that the value does not match because the picture data are base64 decoded and then stored as a picture frame in Kid3. In the case of pictures which cannot be deleted, the value does not match and the frame is not deleted.
the picture), one has to pass the key ("METADATA_BLOCK_PICTURE") and the value (picture data base64 encoded) and both have to match. The problem is that all the frames of the Opus tag are stored in a map in a TagLib object. I can reproduce it and started the debugger to see what's happening. I'm wondering whether external programs write cover art differently? I've amended my music management scripts to write cover art to source files after encoding to Opus. Since the '-discard-pictures' option was only introduced in 0.1.9, encoding to Opus will write cover art from a source file by default. Ubuntu - in the version of Ubuntu I use (14.04 LTS), the version of opus-tools in the repositories is 0.1.8.

Windows - ensuring I use the '-discard-pictures' switch when encoding to Opus, thereby ensuring artless output Opus files. Since my source files always have embedded cover art, I'm currently using the following workarounds: If, however, an external program (either the Opus encoder or different taggers such as MP3Tag or Puddletag) has written cover art to an Opus file, then the 'set picture' command behaviour is modified and removing cover art will fail. Adding new art replaces existing art and 'set picture' can also be used to remove existing art. It therefore appears that when Opus files have no cover art to begin with, then the kid3-cli 'set picture' commands work as expected. However, after adding cover art with the other tagger, kid3-cli 'set picture' commands reverted to their previous behaviour. The results were as expected - setting and removing pictures worked, just as they did with Ogg Vorbis, MP3, etc. I found that running the 'set picture' command on these Opus files added cover art without replacing existing art, and the empty 'set picture' command failed to remove cover art (just as it had in Ubuntu 14.04).īack in Ubuntu, I used a GUI tagger to remove existing art then ran the 'set picture' commands in a terminal. I then encoded some files to Opus without using the '-discard-pictures' switch, thereby ensuring that cover art was copied from the source file during encoding. I also found that using the empty 'set picture' command did indeed remove existing art from the Opus files. that is, rather than adding cover art, it replaced existing cover art. I was pleased to find that the 'set picture' command to add cover art behaved as it does with Ogg Vorbis, MP3, etc.
