I get the following when I capture images using my web-cam..

libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffff
libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffff
libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffff
...(same error repeating)
...

I also had issue that my camera was not getting detected in ubuntu. So, in order to run an application that uses the webcam, I have to run a command like

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so ./6dofhand

Whats causing these errors?
