File contains data in an unknown format. (m4a load from librosa)

So I am currently working on a DNN that takes in m4a files. I have ffmpeg, it creates a few batches and then dies on this error:

I am using this command
wav, sr = librosa.load(path, sr=16000)
is it just a broken file? How do I skip such then? Or is it something about loading a m4a file even with ffmpeg and the desired output when tested on a single m4a file?

Exception has occurred: OSError MoviePy error: failed to read the first frame of video file ****. That might mean that the file is corrupted

WHAT I'M DOING:
Looping a video for a certain amount of time.
However, I'm getting the following error (The file is not corrupt):
Exception has occurred: OSError
MoviePy error: failed to read the first frame of video file Pexels Videos 1292738.mp4. That might mean that the file is corrupted.
at the commented line in my code:
chdir(r'C:\Users\jack_l\Downloads\makeAVideo\stock')
myStock = next(walk(r'C:\Users\jack_l\Downloads\makeAVideo\stock'), (None, None, []))[2]
stockFile = VideoFileClip(str(myStock[0]), target_resolution=(1080, 1920), audio=False)
stockFile = stockFile.loop(duration = 300)
stockFile = stockFile.set_fps(30)
chdir(r'C:\Users\jack_l\Downloads\makeAVideo')
stockFile.write_videofile('theVideo.mp4') # this line
Does anyone know what's going wrong? Any help is greatly appreciated, thank you.

OSError: MoviePy error: failed to read the first frame of video file Pexels Videos 1292738.mp4. That might mean that the file is corrupted. That may also mean that you are using a deprecated version of FFMPEG. On Ubuntu/Debian for instance
the version in the repos is deprecated. Please update to a recent version from the website.

You change folder before write_videofile - and this can make problem.
Code can be "lazy" and it may NOT read file when you define VideoFileClip() but when you want to write new file after changing directory - and it may try to read file from new place.
You should use /full/path/to/Pexels Videos 1292738.mp4 instead of using chdir()

How to read PDF from file storage object in pdf2image?

I am working with flask, where I am uploading a pdf file to convert it to an image and perform OCR using pytesseract.
However, pdf2image is not able to read the uploaded image.
I tried searching on the internet but I could not find anything.
I tried passing the file storage object directly, but am getting an error, my code looks like this:
log_file = request.files.get('pdf')
images = convert_from_path(log_file)
text = ""
for img in images:
im = img
ocr_dict = pytesseract.image_to_data(im, lang='eng', output_type=Output.DICT)
text += " ".join(ocr_dict['text'])
cleaned_text = clean_text(txt=text)
which gives this error,
**TypeError: expected str, bytes or os.PathLike object, not FileStorage**
I also tried doing,
log_file = request.files.get('pdf')
images = convert_from_path(log_file.read())
text = ""
for img in images:
im = img
ocr_dict = pytesseract.image_to_data(im, lang='eng', output_type=Output.DICT)
text += " ".join(ocr_dict['text'])
cleaned_text = clean_text(txt=text)
which gives error:

Okay, it turns out I need to pass convert_from_bytes instead of convert_from_path.

Solving IOError while generating a pdf using reportlab and generated qr code image

I am trying to generate a qr code from text, and then insert into a reportlab pdf.
My code:
def qr_code_as_image(text):
from io import BytesIO
print("In show_qr")
img = generate_qr_code(text)
print(img, type(img))
i = Image(img)
print(i, type(i))
return i

line2 = ("MRD No.", self.linkedcustomer.cstid,

line3 = ("No.", "#", "Doctor", self.doc.name)
datatb = [line1, line2, line3]
patientdetailstable = Table(datatb)
patientdetailstable.setStyle(self.patientdetails_style)
col1 = patientdetailstable
checkin_url = reverse('clinicemr', args=[self.checkin.checkinno])
qr_image = qr_code_as_image(checkin_url)
qr_image.hAlign = 'LEFT'
col2 = Table([[qr_image]])
tblrow1 = Table([[col1, col2]], colWidths=None)
tblrow1.setStyle(self.table_left_top_align)
self.elements.append(tblrow1)

print(os.system(cmd))
print(footer_content, type(footer_content))
doc = SimpleDocTemplate(
temp.name,

From the error, it appears that it is erroring out on getting the name of the image file. But there is no file. The image is being generated from BytesIO.

Your generate_qr_code function, which you did not show us, is NOT returning a BytesIO object. It's returning the raw bytes of the PNG image. When you print(img, type(img)), it told you it was of type "bytes", right? That's a string of bytes, not a BytesIO object. If you wrap those bytes into a BytesIO object, then the reportlab Image constructor will be able to handle it.

how to extract text from web gif file using python

I am trying to extract text from a gif image using the below code, it has worked for png format not working for gif.
import pytesseract
import io
import requests
from PIL import Image
url = requests.get('http://article.sapub.org/email/10.5923.j.aac.20190902.01.gif')
img = Image.open(io.BytesIO(url.content))
text = pytesseract.image_to_string(img)
print(text)
getting this error

The idea is to convert each of the frames to RGB image before performing the OCR on them, as shown below -
for frame in range(0,img.n_frames):
img.seek(frame)
imgrgb = img.convert('RGBA')
imgrgb.show()
text = pytesseract.image_to_string(imgrgb)
print(text)
