Video File Stream ================= Opens a video file as a stream. Input ----- Requires selecting a valid video file. Supported formats are avi, mov, mp4, wmv, ogv and gif. Output ------ Returns a running video stream fed from the file. Description ----------- This IO algorithm loads a video as a file stream, that is frame-by-frame instead of buffering the entire video. Any existing audio or subtitle information is discarded, only plain images are loaded. If the input path does not correspond to a readable video file in one of the supported formats, the algorithm will produce no output.
