problem still occurs, it means that your file has a feature which has not
been implemented.

This used to work. Error appear to be caused by commit
a75a9e8f64ec9660b7c6e16653299f07bfe00f9d which requiring the s->bayer
flag to be set externally. When invoking the jpeg decoder from the command
line like this, the bayer flag is never set.
