Converts a given frame. All the video frames provided by the SDK callback functions are bound to this. If you plan to save the frame so you use it later, you'll need to copy it. In addition to that, if you want to convert a video frame to a different format, you'll use this function also If the destination format is the same as the source, a shallow copy (n buffer copy) will be made if possible.

Parameters

format	The format of the video frame which will be returned. This function can convert frames to the following formats: `OTC_VIDEO_FRAME_FORMAT_ARGB32`, `OTC_VIDEO_FRAME_FORMAT_BGRA32`, `OTC_VIDEO_FRAME_FORMAT_ABGR32`, `OTC_VIDEO_FRAME_FORMAT_RGBA32` and `OTC_VIDEO_FRAME_FORMAT_YUV420P`.
