o FIX - Fixed a nasty problem in zmaudit which meant that
older events sometimes didn't get tidied up and deleted
properly.
o FIX - Fixed an issue with the multi-part jpeg streams
having frame boundaries output at the end of each image and
not the beginning. Apart from this not being ideal
semantically it also meant that ZM had trouble parsing it's
own output!
o FEATURE - Some of the scripts have a new debug format
that is more similar to the one used in the binaries.

@ -4084,26 +4090,26 @@ that image processing for YUV style input formats are now pretty much handled
at almost the same speed as native RGB formats. As this is what the capture
daemons spend most of their time doing, the improvement helps reduce the amount
of CPU time by a significant degree. Application of these changes also
highlighted a bug that had existed previously in YUV conversion which caused incorrect
conversions for certain values. The other two main areas of optimisation are in
the Blend and Delta image functions. Normally when doing motion detection the
analysis daemons spend about 99% of their time comparing a captured image with
the reference image and then blending the two ready for the next capture. Both
of these functions have been significantly improved. In previous versions there
were two options for calculating image deltas (or differences), a simple RGB
average and a Y channel calculation. Historically the RGB one was faster
however with the optimisations the Y channel calculation (which is more
accurate) is now 15-20% faster and so has become the default though you can
select either method by the ZM_Y_IMAGE_DELTAS configuration option. A new
method of image blending has also been added which is up to 6 times faster than
the old one which is retained for compatibility and because in some unusual
circumstances it may still be more accurate (see the ZM_FAST_IMAGE_BLENDS
option for details). Altogether these optimisations (along with other common
sense ones such as not maintaining a reference image in Record mode where it
is not used) significantly reduce the CPU load for most systems, especially
when alarms are not in progress. If an alarm is detected then a lot of file
system and database activity takes place which is limited by the speed of these
resources so the gain will not be as much.</p>
