Smart Automatic Cover Art Downloader
SACAD is a multi platform command line tool to download album covers without manual intervention, ideal for integration in scripts, audio players, etc.
? Features
? Can target specific image size, and find results for high resolution covers
? Support JPEG and PNG formats
? Currently support the following cover sources:
? Last.fm
? Google Images
? Amazon CD (.com, .ca, .cn, .fr, .de, .co.jp and .co.uk variants)
? Amazon digital music
? Smart sorting algorithm to select THE best cover for a given query, using several factors: source reliability, image format, image size, image similarity with reference cover, etc.
? Automatically crunch images with optipng or jpegoptim (can save 30% of filesize without any loss of quality, great for portable players)
? Cache search results locally for faster future search
? Do everything to avoid getting blocked by the sources: hide user-agent and automatically take care of rate limiting
? Automatically convert/resize image if needed
? Multiplatform (Windows/Mac/Linux)
SACAD is designed to be robust and be executed in batch of thousands of queries:
? HTML parsing is done without regex but with the LXML library, which is faster, and more robust to page changes
? When the size of an image reported by a source is not reliable (ie. Google Images), automatically download the first KB of the file to get its real size from the file header
? Process several queries simultaneously (using asyncio), to speed up processing
? Automatically reuse TCP connections (HTTP Keep-Alive), for better performance
? Automatically retry failed HTTP requests
? Music library scan supports all common audio formats (MP3, AAC, Vorbis, FLAC..)
? Cover sources page or API changes are quickly detected, thanks to high test coverage, and SACAD is quickly updated accordingly
