* A MovieVideo is actually any source that provides a sequence of video
* frames. That could include an AVI file, a digital camera, or an internet
* TV station. A MovieVideoCursor is a handle that lets you read data
* sequentially from a MovieVideo.
*
* Thread safety: each individual MovieVideoCursor must be owned and accessed
* by a single thread. It is OK for two different threads to open the same
* file at the same time, as long as they use separate MovieVideoCursor
* objects.
