• 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.

  avfilter/fps : remove unconventional acronyms
  In dd770883e9, support for expressions was added. Among the constants
  
  added were labels of qnstc, qpal, sntsc & spal.
  These were added in ba2a8cb40b to represent parameter permutations where
  
  only the resolution is different. They don't have any usage currency and
  
  don't represent any industry standards or convention in terms of framerate.
