According to the README:
the placeholder image is shown if art has not yet been cached (e.g. on first play of a file), this is because ffmpeg takes anywhere between 1-5+ seconds to perform the extraction, so whatever is available is shown instead of waiting an indeterminate amount of time
Would you consider adding a configuration option to allow waiting until ffmpeg has completed processing the cover art for uncached images? There could be a warning in the documentation about the delay when enabling this option.
