Syntax

INT is_CaptureVideo (HIDS hf, INT Wait)

Description

is_CaptureVideo() digitizes video images in real time and transfers the images to the previously allocated image memory. Alternatively if you are using DirectDraw the images can be transferred to the graphics board. In doing so, the conditions as set out in the is_SetCaptureMode() are taken into account. If you are working with ring buffering (is_AddToSequence()) the image acquisition in the sequence runs through all image memories in a loop.

Parameters

hf | Frame grabber handle
| Wait
IS_DONT_WAIT | This function synchronizes the image acquisition of the next frame and/or V-SYNC field, but returns immediately.
IS_WAIT | This function synchronizes the image acquisition of the next frame and/or V-SYNC field and only then does return (i.e. waits until image acquisition begins).
IS_FORCE_VIDEO_START | Starts digitization immediately (unsynchronized) and returns immediately.
10 < Wait < 32768 | Wait time in 10 ms steps (Wait = 100 > 1 s) A maximum of 328,68 s can be waited. (This is approx. 5 min and 20 s). For 1 < Wait < 10 Wait becomes equal to 10. (Example: Wait = 100 > 1 s waiting)
IS_GET_LIVE | Returns whether the live video is started True: Video has started False: Video has not started

Return value

IS_SUCCESS, IS_NO_SUCCESS

IS_TIMED_OUT (only if the IS_WAIT parameter is used in the triggered sequence mode of the EAGLE and the trigger is not recognized in the next VSYNC)
