django + apache + moviepy - MoviePy error: FFMPEG encountered the following error while writing file

Question

I am trying to extract audio from a video uploaded using moviepy. The code works well during development but i keep getting error after deploying the django app.

def extract_audio(object_id): """This function extracts audio from video""" # Get the object translator_object = Translator.objects.get(pk=object_id) old_audio_file_path = '' if translator_object.source_audio: old_audio_file_path = translator_object.source_audio.path

# raise exceptions
if not translator_object:
    raise Exception("Object not found")
if not translator_object.source_video:
    raise Exception(
        "Video file not available, try again!")

if not os.path.isfile(translator_object.source_video.path):
    raise Exception(
        "Video file not available, try again!")

video_clip = VideoFileClip(translator_object.source_video.path)

new_audio_file_path = str(uuid4())+'.wav'
video_clip.audio.write_audiofile(new_audio_file_path)

translator_object.source_audio = File(open(new_audio_file_path, "rb"))
translator_object.save()

try:
    os.unlink(new_audio_file_path)
    if os.path.isfile(old_audio_file_path):
        os.unlink(old_audio_file_path)
except:
    print('Deleting error..')

error:
