FileNotFoundError in Jupyter Notebook, even though the file is there

This was all written in Jupyter Notebook online. What supposed to happen, is the first line of the code is a command that converts some file in the folder labeled "capstone" into an mp4. This works fine, however the problem I'm running into is a "FileNotFoundError", and I'm not sure why this is happening, as I check to see if the file is there, it is in fact there.

!ffmpeg -i recording1.mov -q:v 0 output.mp4

import librosa
audio_path = '/home/gentry/capstone/output1.mp4'
x , sr = librosa.load(audio_path)
print(type(x), type(sr))

import matplotlib.pyplot as plt
import librosa.display
plt.figure(figsize=(14, 5))

librosa.display.waveplot(x, sr=sr)

X = librosa.stft(x)
Xdb = librosa.amplitude_to_db(abs(X))
plt.figure(figsize=(14, 5))

librosa.display.specshow(Xdb, sr=sr, x_axis='time', y_axis='hz') 

librosa.display.specshow(Xdb, sr=sr, x_axis='time', y_axis='log')

The output should be a visualized waveform of a sound, and two subsequent Fourier transform graphs. I can provide additional details as requested

It is actually just a simple mistake of pathways being different, as this was provided to me by a professor, so audio_path = '/home/gentry/capstone/output1.mp4' should actually just be audio_path = './output1.mp4'

Ok, I will just make small modifications to your code to make all paths relative so the error may not be for wrong manual string path you wrote.

First I ran this command as is:

!ffmpeg -i recording1.mov -q:v 0 output.mp4

then to make sure that I have the output right 

!ls | grep output

that should give you

output.mp4

Then as I know that the file is in the same directory as my notebook, I will make the load command as follows

import librosa
audio_path = './output.mp4'
x , sr = librosa.load(audio_path)
print(type(x), type(sr))

That works perfectly and loads the audio component, my figs maybe totally different than yours as I'm using some random video not your input one as it's not provided
