• MoviePy and FFMPEG "No attribute" errors

  22 mars 2023, par CypherTretii

  I am trying to create a python script that will produce the type of cartoon TikToks with the satisfying video on the bottom part. I am still getting a bunch of errors like "ffmpeg has no attribute "metadata", or some other atribute that is missing"

  


  import os
import random
import hashlib
from moviepy.editor import *

# Function to get MD5 hash of a file
def get_md5_hash(file_path):
    with open(file_path, "rb") as f:
        bytes = f.read()
        hash = hashlib.md5(bytes)
        return hash.hexdigest()

# Input video file path
input_file_path = "C:/Users/Kris/output_movies/Bojack.Horseman.S01E01.720p.WEBRip.x264-W4F_1.mp4"

# Re-render the video
video = VideoFileClip(input_file_path)
video.write_videofile("re_rendered_video.mp4", codec='libx264')

# Change MD5 hash
new_md5_hash = get_md5_hash("re_rendered_video.mp4")
os.rename("re_rendered_video.mp4", f"{new_md5_hash}.mp4")

# Clear ID3 tag metadata
video = VideoFileClip(f"{new_md5_hash}.mp4")
video.reader.metadata.clear()
video.reader.close()

# Choose random video from folder and combine with input video
random_video_path = random.choice(os.listdir("C:/Users/Kris/satisfying_vids"))
random_video = VideoFileClip(f"C:/Users/Kris/satisfying_vids/{random_video_path}")

# Ensure the bottom video is at least as long as the input video
while random_video.duration < video.duration:
    if random_video.duration * 2 <= video.duration:
        random_video = concatenate_videoclips([random_video, random_video])
    else:
        duration_diff = video.duration - random_video.duration
        looped_video = random_video.subclip(0, duration_diff)
        random_video = concatenate_videoclips([random_video, looped_video])

# If the concatenated video exceeds the length of the input video, trim it
if random_video.duration > video.duration:
    random_video = random_video.subclip(0, video.duration)

# Resize the bottom video to match the input video resolution
random_video_resized = random_video.resize((960, 540))

# Combine the videos in 1:1 aspect ratio with the bottom video at the bottom of the screen
final_video = clips_array([[video], [random_video_resized]])

# Save the final video with .mp4 format
final_video.write_videofile(f"{new_md5_hash}_combined.mp4", codec='libx264')


# Increase brightness and contrast
final_video = VideoFileClip(f"{new_md5_hash}_combined.mp4")
final_video = final_video.fx(vfx.colorx, 0, [random.uniform(-0.2, 0.2), random.uniform(-1, 1)])
final_video.write_videofile(f"{new_md5_hash}_processed.mp4", codec='libx264')

# Color one pixel black and crop one pixel from bottom right corner
final_video = VideoFileClip(f"{new_md5_hash}_processed.mp4")
final_video = final_video.fx(vfx.painting, paint_color=[0,0,0], width=1, height=1, x=0, y=0)
final_video = final_video.crop(x1=0, y1=0, x2=final_video.w-1, y2=final_video.h-1)
final_video.write_videofile(f"{new_md5_hash}_final.mp4", codec='libx264')



  


  the goal for the code is :

  


  Takes an .mp4 file as input (the file is 1920 x 1080 in terms of resolution)

  


  Re-renders the video

  


  Changes the MD5 Hash

  


  Clears ID3 Tag Metadata

  


  Choses another random video from a folder, that is 1920 x 1080 pixels in terms of resolution - combine the chosen video with the input video in 1:1 aspect ratio. Put the video that is randomly chosen from the folder on bottom side of the screen.

  


  Increase the video’s brightness by random number ranging from -0.2 to 0.2

  


  Increase contrast by random number ranging from -1 to 1

  


  Color one pixel black

  


  Crop 1 pixel from the down right angle

  


  Save the final video with .mp4 format

  


  This is the error I am getting when running my code :
AttributeError : 'FFMPEG_VideoReader' object has no attribute 'metadata'

  


  Along with various missing attributes.

  


• Piwik now integrated within CloudFlare

  8 novembre 2017, par Piwik Core Team — Development

  Would you like to know some quick fix in order to make your website load faster ? Would you like your users to have a better experience on your website ? One answer to that is what we call a CDN. Content Delivery Network (CDN) is a system of distributed servers that deliver content to a user based on various criterias such as geolocation.

  And the good news for you is that Piwik got recently integrated to a popular CDN : CloudFlare.

  What is CloudFlare ?

  As previously said, CloudFlare is a content delivery network (CDN).

  

  The three major advantages of using CloudFlare as a CDN are :

  • it is making your website load faster by providing a nearby location to your files to users
  • it also help detecting potential attacks like DDoS and takes away these risks for you
  • it runs one of the largest, fastest, and most reliable managed DNS service in the world

  Automatically add Piwik tracking code to your website

  With the integration of Piwik to CloudFlare, you can now deploy the Piwik tracking code directly through your CloudFlare account instead of tweaking the source code of your website.

  In order to do that, all you need is to log in to your CloudFlare account and click on “Apps”. Then look for Piwik within the search bar :

  

  Once done, click on “Preview” on your site to enter your credentials (Piwik URL and website ID) :

  

  Click “install” to finish the setup. The Piwik tracking code is now installed on each page of your website.

  If you have previously added the tracking code manually to your website and now use the Piwik app, don’t forget to remove the tracking code from your website. Otherwise you end up tracking every user twice.

  Important note : the Piwik CloudFlare integration only concerns the Piwik tracking code integration. For the Piwik app on Cloudflare to work you will need to have a running Piwik installed on your server, or you can start a free trial on the Piwik Analytics Cloud.
