1. When I synchronize my handheld device (folder on sd-card) through MC-client with transcode option (flac -> mp3 in my case, but in general I think with any transcoding). After sync I have mp3 files without any text tags, but with covers - transcoding option "Cover Art - add to tag" works ok. In my library I do not keep cover in file tags for various reasons, and in this sync scenario external cover from library is сorrectly applied to the files.
2. When I synchronize my handheld device (folder on sd-card) through MC-client without transcoding. In this case I have original flac files with all text tags, but with no covers in tag - as a result, many portable players do not see the cover. The option "Enable album artwork support if possible" does not help, the option "Cover Art - add to tag" for now works only with transcoding.
As result I was able to sync portable player without text tags or without a cover.
The DLNA server handles the tags in a similar way:
When I save the tracks through the DLNA server (21st century sync tool
, I do it with BubbleUPnP app on Android phone or by SmartStor Fusion Stream App on IOS), if transcode on server side is disabled, I get a valid file (flac, mp3) with all tags except for the cover. If transcoding on DLNA server is enable, I save tracks without any text and cover tags.
Perhaps it my specific configuration? I will be glad to hear opinions.
Thanks
