Hi, 

import imageio

reader = imageio.get_reader('../data/p1ch4/video-cockatoo/cockatoo.mp4')
meta = reader.get_meta_data()
meta
{'plugin': 'ffmpeg',
 'nframes': inf,
 'ffmpeg_version': '4.2.2 built with gcc 9.2.1 (GCC) 20200122',
 'codec': 'h264',
 'pix_fmt': 'yuv444p',
 'audio_codec': 'mp3',
 'fps': 20.0,
 'source_size': (1280, 720),
 'size': (1280, 720),
 'rotate': 0,
 'duration': 14.0}

Can anyone tell me why the 'nframes': inf, is inf? Thanks a lot.
