Everytime I run the code it does this.


code :


import praw
import requests
import cv2
import os
from pydub import AudioSegment

def download_video(url, filename):
 response = requests.get(url)
 with open(filename, 'wb') as f:
 f.write(response.content)

 video_clips = []
 audio_clips = []
 for i, url in enumerate(video_urls):
 temp_filename = f'temp_video_{i}.mp4'
 download_video(url, temp_filename)
 video_clip = cv2.VideoCapture(temp_filename)
 audio_clip = AudioSegment.from_file(temp_filename, format="mp4")
 video_clips.append(video_clip)
 audio_clips.append(audio_clip)
 
 if not video_clips:
 print("No video clips to combine.")
 return

 frame_width = int(video_clips[0].get(cv2.CAP_PROP_FRAME_WIDTH))
 frame_height = int(video_clips[0].get(cv2.CAP_PROP_FRAME_HEIGHT))
 fps = int(video_clips[0].get(cv2.CAP_PROP_FPS))

 fourcc = cv2.VideoWriter_fourcc(*'mp4v')
 output_clip = cv2.VideoWriter(output_filename, fourcc, fps, (frame_width, frame_height))

 for i, video_clip in enumerate(video_clips):
 while True:
 ret, frame = video_clip.read()
 if not ret:
 break
 output_clip.write(frame)
 
 for video_clip in video_clips:
 video_clip.release()
 
 output_clip.release()

 # Combining audio using pydub
 combined_audio = sum(audio_clips)
 combined_audio.export("combined_audio.mp3", format="mp3")

 # Merging audio with video using ffmpeg
 os.system(f'ffmpeg -i {output_filename} -i combined_audio.mp3 -c:v copy -c:a aac -strict experimental -map 0:v:0 -map 1:a:0 final_output.mp4')

 # Cleaning up temporary files

def main():
 reddit = praw.Reddit(
 client_id='XXX',
 client_secret='XXX',
 user_agent='Reddit Video Downloader'
 )
 
 subreddit_name = input("Enter the name of the subreddit: ")
 limit = int(input("Enter the number of videos to download: "))
 
 subreddit = reddit.subreddit(subreddit_name)
 submissions = subreddit.hot(limit=limit)

 if video_urls:

 combine_videos(video_urls, output_filename)
 print("Videos combined successfully!")
 else:
 print("No Reddit videos found in the subreddit.")

if __name__ == "__main__":
 main()



Anyone got any idea why this happens ?


I'm making a script that scrapes videos from a specific subreddit.


Also if it helps the temp video file is corrupted when it gets made.


I've put this into chatGPT as well and brought an expert friend and he hasn't been able to help me.

The latest ffmpeg shows "get_buffer() failed". Is this a bug ?
20 juin 2023, par Ryanffmpeg version 2023-06-19-git-1617d1a752-full_build-www.gyan.dev


i7-1255U, Windows 11


The command line is


"ffmpeg.exe" -y -hwaccel qsv -ss 00:00:03.461 -to 00:00:12.009 -i "input.mov" -c:v h264_qsv -global_quality 25 -look_ahead 1 -preset veryslow -c:a aac -ar 48000 -ac 2 -ab 128k output.mp4



The "input.mov" is mjpeg.


The result is :


[mjpeg_qsv @ 0000019930260080] get_buffer() failed
[vist#0:0/mjpeg @ 000001993025ff00] Error submitting packet to decoder: Cannot allocate memory

The messages above repeats many many many times. Finally, it shows :


[vist#0:0/mjpeg @ 000001993025ff00] Error submitting EOF to decoder: Cannot allocate memory



I tried the same command line on a very old version, and it works fine. Is this a bug or there is something new that comes with the new version ?


Thank you for your help.
