Can I set the start number for image sequence output? I am using ffmpeg to convert from video to an image sequence as follows:

ffmpeg -i video.webm image-%03d.png


The first image is labelled 001, but I want it to be labelled 098. Is it possible to set that value in the ffmpeg invocation?
The image sequence muxer has a start number option, so

ffmpeg -i video.webm -start_number 98 image-%03d.png
