problem while loading/decoding the input video ?

[crasse2]

Hi !

i'm trying to interpolate a video and it seems the process doesn't decode correctly the input video to interpolate :

me > python inference_video.py --exp=1 --video=test_90.mp4

and it starts with

Loaded v2.x HD model.
test_90.mp4, **0.0 frames in total, 0.0FPS to 0.0FPS**

and obviously it doesn't produce any interpolated file, and it seems to start with this weird 0.0 frames aand FPS statement

here is the full log :

Loaded v2.x HD model.
test_90.mp4, 0.0 frames in total, 0.0FPS to 0.0FPS
The audio will be merged after interpolation process

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "inference_video.py", line 288, in <module>
    os.rename(targetNoAudio, vid_out_name)
FileNotFoundError: [Errno 2] No such file or directory: 'test_90_2X_0fps_noaudio.mp4' -> 'test_90_2X_0fps.mp4'

I can see that the process find somehow that the video is 595 frames long as it does 595 iteration, but it doesn't produce anything. any idea of what is missing or not working here ?
