3d10570a8e niimaqsrc: handle latency query and drop unneeded get_times method 2014-01-24 10:02:59 -05:00

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.

97b2e8be4c niimaqsrc: Timestamp buffers based on time from callback on FRAME_START line 
This timestamp should be much more accurate than the time retrieved in GstPushSrc.create, as there should be no latency (or very little).

bfdbf89aa8 niimaqsrc: Output caps supports both actual bpp and bpp=16 
The src caps now have two structures, the first contains the actual bpp of the camera, (10, 12, or 14), and the second has the standard bpp=16. This enables the element to be used both with ffmpegcolorspace (and other elements which only accept bpp=16) but also with our elements like videolevels.

af25506097 niimaqsrc: Fix caps negotiation 
Set caps to src pad during GstBaseSrc.start.
Use static pad templates instead of dynamically generating caps.
Force bpp to 16 even if IMAQ says 10, 12, 14 (to be fixed in the future by implementing GstBaseSrc.negotiate).
