1033aea633 niimaqsrc: another attempt at robust date-timestamping 
Before indices would get out of sync. Try mutexes now.

5e8744d492 niimaqsrc: remove assert, as timestamps aren't always retrieved correctly 2014-01-24 10:03:00 -05:00

a9cfe6062d niimaqsrc: use simpler method of correlating buffers with timestamps 
Drop the mutexes and special struct, just create ring buffer of
GstClockTimes. Also rely on callbacks for start/stop of acquisition.

The absolute date-timestamps need to be corrected for the first buffer
timestamp.

5d5d1085b7 videolevels: use lut for conversion (again) 
Faster, but could maybe be faster still using orc.

d6fe385cb9 niimaqsrc: add avoid copy mode 
Unfortunately IMAQ only lets you examine one buffer at a time, and elements
like queue store up multiple buffers, so avoid-copy=TRUE can only be used in
pipelines without queues or other such elements.

Also, make property strings static.

ad240b0ae3 niimaq: try to improve accuracy of timestamping 
By reducing instructions in callback, and adjusting for base time. This last
part needs testing however.

9002eb1f70 niimaq: handle byte alignment during copying 
Previously if the row stride wasn't a multiple of 4, display would not work
correctly. Rely on NI-IMAQ to fix the byte alignment for us. This hasn't
been thoroughly tested yet however.

7c251fa83a niimaq: use standard video caps 
Even though NI-IMAQ can specify 10-, 12-, or 14-bit images, no other standard
element supports it, and in 0.11/1.0 caps are simplified to be gray8/gray16.
We can always add back custom caps if there is a real need for it.

fa883c1ca1 niimaq: make sure timelist exists before modifying it 
Caused seg fault unless delay was introduced (e.g. with debugging messages
on). Still need to investigate why we don't get a timestamp before the
first frame.

cca79973df phoenix: more accurate timestamps, duration and dropped frame count 
Timestamp and duration now set using Phoenix timer, recorded at frame start and end (FVAL high then low).

Only more than one dropped frame can be reliably detected.

Caps aren't correct, but I can correctly save camera output to file.

Many printfs are sprinkled about as I'm having trouble with gst-debug, will remove later.
