SaveToVideo_C.c

SaveToVideo_C.c shows how to create a video from a vector of images.It relies on information provided in the Enumeration_C , Acquisition_C, and NodeMapInfo_C examples.

This example introduces the SpinVideo class, which is used to quickly and easily create various types of video files. It demonstrates the creation of four types: uncompressed, MJPG, H264 (AVI) and H264 (MP4).
