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.

Original SOF3
<http://s000.tinyupload.com/index.php?file_id=22297762703192557889> -> 
ffmpeg converted JPEG-LS

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

Thanks for your time!

best regards
