ValidateJPeg crash #478

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Validate jpeg has been reported with logotech c9000 camera frames on linux.
C9000 has known framing errors.
Invalid frames will be passed to ValidateJPeg.  But it should gracefully fail.

fixed by scanning from start of buffer.
consider followup that avoids ValidateJpeg call in jpeg decoder.  Have calling 
code run Validate.
