Cover art lost when converting from
opus
#122
Comments
If you drop the file that is to be converted onto LameXP and go to "Show Details", does it show the artwork? If not, it means that no artwork has been found in the source file, and thus there can not be any artwork in the converted file. |
Wasn't aware of the "Show Details" fucntionality. Upon inspection, it would seem that LameXP is unable to read artwork from opus files, even those it has itself created(doesn't show up in details). The artwork is there, players read it, Mp3tag reads it etc. I even removed the artwork that LXP carried over from the original mp3 file and re-added it via Mp3tag, with the same results. It's easy to replicate, but I can creata a small sample file if it'd help. |
LameXP is just a GUI front-end, and "under the hood" it uses MediaInfo to extract meta information from the source file. If you analyze your source file with You should run this from the terminal:
(Note: this is the command that LameXP would execute internally) If MediaInfo doesn't find any cover artwork in the Opus file, I think this would be a feature request for MediaInfo 😳 If MediaInfo does find (and output) cover artwork in the Opus file, but LameXP somehow doesn't parse the output of MediaInfo correctly, then this is something I should be looking into... |
mediainfo output for source mp3 file(created itself with LXP):
mediainfo output for output opus file(created from the mp3 above):
So the artwork does show up, but not a separare "track" as in the original mp3. Again, plese let me know if you want this sample file, though you should be able to replicate with any file. THis doesn't seem to me like it has anything to do with the sample itself. |
Can you please run MediaInfo with options |
There weas a typo and I just copied and pasted the commadn without thinking. Sorry about that. Including the command ran below. mediainfo output for source mp3 file(created itself with LXP):
mediainfo output for output opus file(created from the mp3 above):

Okay, thanks. I think this needs more in-depth analysis when I have more time. But I think it could be related to the lack of the Maybe we need to assume JPEG by default, if that is missing? (BTW: indeed, there was a typo in the command-line arguments in my above post, sorry for that) |
I am unable to help answer any of those questions, but I can pile on one more: why does LameXP(opusenc?) not output that mime type and the Anyway, thank you for your time and patience, M'lord! |
@lordmulder Quick question, if I may: why have you opted for |
In my (limited) experience with LameXP, converting whichever way between flac, mp3 and opus retains the embedded cover image, if present in te source file, with one exception: converting from opus to any other format.
Steps to reproduce: convert a file with embedded cover art from any other format to opus, then convert the resulting file to mp3.
