Hi,
i'm using ffmpeg to convert old JPEG-SOF3 lossless images into JPEG-LS
lossless. I've encountered the problem that some images are cut after
some kiloBytes. The Sof-3 Header seems correct for me. The ScanData-Tag
contains 121475 bytes.
However in the converted JPEG-LS the ScanData is only 5149 Bytes.

I've used following command:
ffmpeg -y -i big.sof3 -vcodec jpegls -q:v 0 test.jls
Thanks for your time!
