I am currently using python to download a mp4 file from the internet, convert it to mp3 then delete the mp4 file. I wanted to run this process 3 at a time so I used threading. However, it gave me winerror32 when I was accessing the folder where the mp4 was downloaded.
I think it because one thread is accessing the folder at the same time as the other thread. Is there way to force the thread to access the folder one at a time?
I tried using lock to only allow one thread at a time but it did not work
def download_multi(music,links,check,parent_file,default_filename,success,fail,total):
try:
lock = threading.Lock()
lock.acquire()
print(format(threading.currentThread().getName()))
print("Downloading- ", str(check), "/", total, default_filename + "...")
check += 1
lock.release()
# downloads first audio stream
music.download(parent_file)
# creates mp3 filename for downloaded file
new_filename = default_filename[0:-3] + "mp3"
print("\nConverting to mp3....")
# converts mp4 audio to mp3 audio
lock.acquire()
audioclip = VideoFileClip(os.path.join(parent_file, default_filename))
audioclip.audio.write_audiofile(os.path.join(parent_file, new_filename))
# print("Download finished.")
# end the video process
audioclip.close()
# erase mp4
if os.path.isfile(parent_file + "\\" + default_filename):
os.remove(parent_file + "\\" + default_filename)
print(default_filename + "delete complete\n")
# list that would be added to log file
success.append(default_filename)
lock.release()
except Exception as e:
print(e)
print("unable to download " + default_filename)
# list that would be added to log file
fail.append(default_filename)
pass
The problem was that I was passing wrong parameters to the method. The code itself does not have a problem
