VideoSnapshot

VideoSnapshot creates a bitmap snapshot for the specified position of the given video file. The snapshot is displayed instead of the video.

ret = VideoSnapshot(hVideo)

ret = VideoSnapshot(hVideo, ssBitmapFile)

ret = VideoSnapshot(hVideo, ssBitmapFile, pos)

ret = VideoSnapshot(hVideo, ssBitmapFile, pos, ssVideoFile)

Return Value

ret

Parameters

hVideo

hVideo is the handle of the video object.

ssBitmapFile

ssBitmapFile is the complete bitmap file.

pos

pos is the position in milliseconds or -1 for the current position.

ssVideoFile

ssVideoFile is the name of the video file.

Comment

If FFmpeg.exe is installed and the path name is set in the environment variable path, the program is used to create the snapshot. (see http://www.ffmpeg.org und https://de.wikipedia.org/wiki/FFmpeg).

If FFmpeg.exe is not found, DirectX (DirectShow) is used to create the snapshot. Sometimes the DirectX function fails to create the bitmap. Therefore FFmpeg.exe is preferable.
