Dear all, When try to resize some jpeg file, I got an error 256 with the following messages: ffmpeg version CVS, build 3276800, Copyright (c) 2000-2004 Fabrice Bellard configuration: built on Oct 18 2005 23:48:18, gcc: 3.3.5 (Debian 1:3.3.5-13) [mjpeg @ 0x83903b0]mjpeg: unsupported coding type (c2) The command I was using was: ffmpeg/ffmpeg_CVS/ffmpeg -f image2 -i '/home//xz/src/otter1/A1_origin.jpg' -f image2 -s 100x100 -sameq -y '/home/xz/dst/otter1/A1_thumbnail.jpg' What is the "c2" type, and how can I get it work? Thanks in advance. Xiaogang Zhang
