How to merge audio and video file using ffmpeg in python?

I need to merge both audio and video using ffmpeg in python 3.7,could you help me to solve this issue?
Here i used code :
from pathlib import Path
glob_path = Path(r"D:\t")
file_name = [str(pp) for pp in glob_path.glob(r'**/*.mp4')]
print(file_name)
video_stream = ffmpeg.input(file_name[0])
audio_stream = ffmpeg.input(file_name[1])
print(video_stream)
print(audio_stream)
ffmpeg.output(audio_stream, video_stream, 'out.mp4').run()
I getting this out put error
['D:\\t\\audio.mp4', 'D:\\t\\video.mp4']
input(filename='D:\\t\\audio.mp4')[None] <b0ebefda3dca>
input(filename='D:\\t\\video.mp4')[None] <388c87446fd1>
Traceback (most recent call last):
File "C:\Users\LENOVO\PycharmProjects\calc_new\udownlod.py", line 18, in <module>
ffmpeg.output(audio_stream, video_stream, 'out.mp4').run()

FileNotFoundError: [WinError 2] The system cannot find the file specified

Looks like one of the files cannot be found. The best thing to do is to check if both files exist at the specified locations.
FileNotFoundError: [WinError 2] The system cannot find the file specified

Even though it was shown path error, that error was in installation package, i used
conda install -c menpo ffmpeg
in https://anaconda.org/menpo/ffmpeg , solved my issue

Simple HTML to PDF python library error

I'm using this pydf to convert HTML to a PDF on our server. This is an example that comes right from their docs that illustrates the problem:
import pydf
pdf = pydf.generate_pdf('<h1>this is html</h1>')
with open('test_doc.pdf', 'wb') as f:
f.write(pdf)
When I go to run this file, I get the same error everytime:
(pdf) <computer>:<folder> <user>$ python pdf.py
Traceback (most recent call last):
File "pdf.py", line 3, in <module>
pdf = pydf.generate_pdf('<h1>this is html</h1>')

I'm running this in a virtualenv and my pip freeze is only the following:
python-pdf==0.30
Any idea what could be going wrong here?

As you are using macOS, you need to download a wkhtmltopdf binary by your own:
pydf comes bundled with a wkhtmltopdf binary which will only work on Linux amd64 architectures. If you're on another OS or architecture your milage may vary, it is likely that you'll need to supply your own wkhtmltopdf binary and point pydf towards it by setting the WKHTMLTOPDF_PATH variable.

Trying Tesseract on Windows CMD

I'm having trouble using Tesseract-OCR with the pytesseract Python wrapper.
I figured that the problem might come from Tesseract itself, not from the wrapper.
So I tried Tesseract in CMD :
C:\Users\Thomas\Desktop>tesseract.exe 'blabla.jpg' 'out.txt'
And it returned the following lines :
Tesseract Open Source OCR Engine v3.05.01 with Leptonica
Error in fopenReadStream: file not found
Error in findFileFormat: image file not found
Error during processing.
I've done the following to install Tesseract :
Installing from there : https://github.com/UB-Mannheim/tesseract/wiki
Adding the path of tesseract.exe to the PATH environment variable
And by the way, the problem I'm having where running my Python code :
from PIL import Image
import pytesseract
text = pytesseract.image_to_string(Image.open('blabla.jpg')
print(text)
is :
Traceback (most recent call last):
File "<ipython-input-1-01e77f902509>", line 1, in <module>

File "D:\anaconda\lib\subprocess.py", line 990, in _execute_child
startupinfo)
PermissionError: [WinError 5] Access refused
Running the code as Administrator doesn't solve the problem
Thanks a lot for your help !

Firstly, to verify tesseract works or not from Windows command prompt, use " " instead of ' ' if the image and/or output file name consists of space. Otherwise quote symbol is not needed.
C:\Users\Thomas\Desktop>tesseract.exe blabla.jpg out.txt
Secondly, use full file path to specifc the image file. Such as,
pytesseract.pytesseract.tesseract_cmd = 'C:/path/to/tesseract.exe'
text = pytesseract.image_to_string(Image.open('D:/path/to/blabla.jpg'))
Note that forward slash / is used to specific any file path instead of backslash \ , or you use double backslash \\, e.g. 'D:\\path\\to\\blabla.jpg'.
Hope this help.

How can I get Python to find ffprobe?

I have ffmpeg and ffprobe installed on my mac (macOS Sierra), and I have added their path to PATH. I can run them from terminal.
I am trying to use ffprobe to get the width and height of a video file using the following code:
import subprocess
import shlex
import json
# function to find the resolution of the input video file
def findVideoResolution(pathToInputVideo):
cmd = "ffprobe -v quiet -print_format json -show_streams"
args = shlex.split(cmd)
args.append(pathToInputVideo)
# run the ffprobe process, decode stdout into utf-8 & convert to JSON
ffprobeOutput = subprocess.check_output(args).decode('utf-8')
ffprobeOutput = json.loads(ffprobeOutput)
# find height and width
height = ffprobeOutput['streams'][0]['height']
width = ffprobeOutput['streams'][0]['width']
return height, width
h, w = findVideoResolution("/Users/tomburrows/Documents/qfpics/user1/order1/movie.mov")
print(h, w)
I am sorry I cannot provide a MCVE, as I didn't write this code, and I don't really know how it works.
It gives the following error:
Traceback (most recent call last):
File "/Users/tomburrows/Dropbox/Moviepy Tests/get_dimensions.py", line 21, in <module>
h, w = findVideoResolution("/Users/tomburrows/Documents/qfpics/user1/order1/movie.mov")

raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'ffprobe'
If python is not reading from the PATH file, how can I specify where ffprobe is?
Edit:
It appears the python path is not aligned with my shell path.
Using os.environ["PATH"]+=":/the_path/of/ffprobe/dir" at the beginning of each program allows me to use ffprobe, but why might my python path not be the same as my shell path?

You may use
import os
print os.environ['PATH']
to verify/validate that ffprobe is in your python environment. According to the error you have, it is likely not.

Error in opening image file in PIL

I am trying to execute the following code
from pytesser import *
import Image
i="C:/Documents and Settings/Administrator/Desktop/attachments/R1PNDTCB.jpg"
print i
im = Image.open(i.strip())
text = image_to_string(im)
print text
I get the following error

Can someone please explain what I am doing wrong here.
Renamed the image file.Shifted the python file and the images to a new folder. Shifted the folder to E drive
Now the code is as follows:
from pytesser import *
import Image
import os
i=os.path.join("E:\\","ocr","a.jpg")
print i
im = Image.open(i.strip())
text = image_to_string(im)
print text
Now the error is as follows:
E:\ocr\a.jpg
Traceback (most recent call last):

errread, errwrite)

WindowsError: [Error 2] The system cannot find the file specified

You need to install Tesseract first. Just installing pytesseract is not enough. Then edit the tesseract_cmd variable in pytesseract.py to point the the tessseract binary. For example, in my installation I set it to
tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe'

The exception is pretty clear: the file either doesn't exist, or you lack sufficient permissions to access it. If neither is the case, please provide evidence (e.g. relevant dir commands with output, run as the same user).

your image path maybe?
i="C:\\Documents and Settings\\Administrator\\Desktop\\attachments\\R1PNDTCB.jpg"
try this:
import os
os.path.join("C:\\", "Documents and Settings", "Administrator")
you should get a string similar to the one in the previous line

Try this first:
os.path.expanduser('~/Desktop/attachments/R1PNDTCB.jpg')
It could be that the space in the 'Documents and Settings' is causing this problem.
EDIT:
Use os.path.join so it uses the correct directory separator.

Just add these two lines in your code
import OS
os.chdir('C:\Python27\Lib\site-packages\pytesser')
before
from pytesser import *

If you are using pytesseract, you have to make sure that you have installed Tesseract-OCR in your system. After that you have to insert the path of the tesseract in your code, as below
from PIL import Image
import pytesseract
pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract
OCR/tesseract'
You can download the Tesseract-OCR form https://github.com/UB-Mannheim/tesseract/wiki
