:read_video_frame()
:to_ascii()
print(ascii_frame)
Torch
If you have Torch installed, load the enhanced version of the library.
local ffmpeg = require('ffmpeg.torch')
local byte_tensor = ffmpeg.new('./example.mpg')
:filter('rgb24', 'scale=512:512')
:read_video_frame()
:to_byte_tensor()
local float_tensor = first_frame_tensor:float():div(255)
