OptionalfilenameFile name for the file target, used as it is instead of the derived one (no extension is added); must be a plain name without separators or traversal.
The image as plain Base64, without a Data URL header or a base64: marker. Characters outside the Base64 alphabet are skipped and decoding stops at the first =; input that decodes to no bytes fails with INVALID_PARAMS.
Track path. The embedded target writes into this file, which needs a format the album art editor supports; the file target writes into its directory with a |subsong:N suffix dropped, so every track of a CUE sheet shares one image.
OptionaltargetWhere to write: embedded (into the file's tags), file (an image next to the audio file, named after type, cover for the front picture, with the extension read from the image bytes), or all for both; several entries write to each. Omitted, it writes embedded. Any other value fails with INVALID_PARAMS.
OptionaltypePicture type.
Parameters for
metadata.embedArtwork. Write a picture into a track's tags, into an image file next to it, or both. With one target the result describes that write; with both, each target's outcome is reported underresultsand the call fails withOPERATION_FAILEDonly when both failed.
