I would like to convert png animation file to gif in windows, I choose to use ffmpeg, as I have many of pngs to covert, cmd is quite straight forward in this case.
the sample img here:

tried:
ffmpeg -i SPGGMEb.png -vocdec gif output.gif
everything seems fine but the transparent background turns to black, as:

how can I keep the transparent background during conversion?
