Disappearing artwork when playing to a remote zone

(1/5) > >>

I tried a new configuration and ran into a new and surprising bug. I wonder if anyone else has seen this.

Short version: when playing a song with the destination zone as a remote Mac running MC, MC thinks that the song's artwork disappears after it plays.

Long version:


* One copy of MC on Mac "A" with local library.
* Destination zone is MC on Mac "B".
* Pick a song (on Mac "A") with artwork embedded in the audio file. Play it (to zone on Mac "B").
* Here's the bug: When song is finished playing, JRiver on Mac "A" now thinks the song no longer has artwork. Look at its tag in MC, "Image" says "no image". Before playing the song, MC thought it had an image.
* External tools (e.g. Metadatics) show that the artwork is still embedded in the file after bug occurs.
* The problem (the disappearing artwork) happens both when playing a track while sitting at Mac "A" and using MC directly, and when playing via Remote.
* The audio file in question is not changed by MC.
* Happens with both AAC and FLAC files.
* MC is configured to *not* store artwork or tags in audio files.
* When playing locally on Mac "A" to itself ("player"), the problem does not occur.
* When playing on Mac "B", loading the library from Mac "A", locally to Mac "B"'s player, the problem does not occur.
* Quitting and restarting MC does not fix the problem.
Mac "A": 2017 iMac, macOS 11.2.1, MC 27.0.62.
Mac "B": 2014 Mac mini, macOS 11.2.1, MC 27.0.35.

Has anyone else seen this? Thanks.

And a followup question...what's a good way to get MC to recognize the artwork from the files that it now thinks have none? I have a fair number of these now (audio files which have embedded artwork but which MC thinks have no artwork). I'd like to avoid manually extracting their artwork with an external tool and adding it in, a file at a time, in MC... Thanks.

If you are trying to view the tag with the remote MC zone selected, you are not seeing the original file, you are seeing the results of what the DLNA renderer (the other MC) has in it's content directory.
If you are doing conversion to any format other than original (wave, mp3, DSF) there won't be a tag on the file in any case. The cover art is sent as part of the DLNA process. Even if it is original format, you are likely not going to see it because as I say you are only seeing the info DLNA provides from the renderer.

If the file list in in a local player zone and it does have embedded artwork and you are NOT seeing it as a thumb in MC's database you can right-click on the files(s) and do Cover Art->Rebuild Thumbnail.

I tried that. Neither the thumbnail nor the full-size image returned. The image is still in the file. MC's Tag window says "no image". No thumbnail shown.
