can I get frame image filename in imiter when using ffmpeg plugin?

[zshnb]

background

I want to know every frame's time in video

explain

I try to use below code to go throuth the whole frame

reader = imageio.imiter('/path')
for im in reader:
    print(im)

in ffmpeg if I add -frame-pts then ffmpeg will append frameNumber to filename like 234.jpg
can I also get the filename in iter?
if not how can I get the frame's time in video?
