Hollywood is a python library that generates video files with common situations used in the QA process of video analysis software.
Example code:
from hollywood import Hollywood
h = Hollywood()
h.show_person(3) # shows a person for 3 seconds
h.wait(1) # 1 second of blank video
h.show_person(10, num_persons=5) # shows 5 persons for 10 seconds
h.close_video() # saves the video file as video.aviYou can find more examples of usage in the sample.py file
You can convert the output using ffmpeg:
ffmpeg -y -i video.avi video.mp4
