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.

The difference between a MovieVideo and a MovieVideoCursor is like the difference between a filename and a file handle. The MovieVideo just indicates a particular movie. The MovieVideoCursor is what allows access.

__init__()¶: This constructor returns a null video stream — a stream of plain blue and white frames that last one second each. To get more interesting video, you need to construct a subclass of this class.

property filename → Filename¶: Returns the movie’s filename. A movie is not guaranteed to have a filename, if not, then this function returns an empty filename.

static get()¶: Obtains a MovieVideo that references a file. Just calls MovieTypeRegistry::make_video().

static get_class_type()¶

get_filename()¶: Returns the movie’s filename. A movie is not guaranteed to have a filename, if not, then this function returns an empty filename.

get_subfile_info()¶: If the movie is to be loaded from a subfile on disk, this returns the subfile info. Check info.is_empty() to see if this is valid data.

open()¶: Open this video, returning a MovieVideoCursor of the appropriate type. Returns NULL on error.

property subfile_info → SubfileInfo¶: If the movie is to be loaded from a subfile on disk, this returns the subfile info. Check info.is_empty() to see if this is valid data.
