• Deprecation error when using imageio.ffmpeg.download()

  29 novembre 2022, par SHASHIKUMAR B J

  I'm trying to merge the prerecorded videos using python Opencv.
But i'm getting the error while importing.

  



  "Traceback (most recent call last):&#xA;  File "video.py", line 4, in <module>&#xA;    from moviepy. editor import VideoFileClip,concatenate_videoclips &#xA;  File "/home/pi/.virtualenvs/cv/lib/python3.5/site-packages/moviepy/editor.py", line 26, in <module>&#xA;    imageio.plugins.ffmpeg.download()&#xA;  File "/home/pi/.virtualenvs/cv/lib/python3.5/site-packages/imageio/plugins/ffmpeg.py", line 40, in download&#xA;    "imageio.ffmpeg.download() has been deprecated. "&#xA;RuntimeError: imageio.ffmpeg.download() has been deprecated. Use &#x27;pip install imageio-ffmpeg&#x27; instead.&#x27;"&#xA;</module></module>

  



  would anyone please help to get out of this problem

  



  Here is the code :

  



  import cv2 
import os 
import time 
from moviepy.editor import VideoFileClip,concatenate_videoclips 
def vidcapt():
    a = time.strftime("%H,%M,%S")
    cap = cv2.VideoCapture(0)
    fourcc = cv2.VideoWriter_fourcc(*'XVID')
    out = cv2.VideoWriter(a+'.avi', fourcc, 24.0, (640,480))
    t1 = time.time()
    while(cap.isOpened()):
            ret, frame = cap.read() 
            if ret == True:
                    out.write(frame)
                    cv2.imshow('frame',frame)
                    t2 = time.time()
                    time_diff = t2-t1
                    if time_diff >= 5:
                            break
            else:
                    break
    cap.release()
    out.release()
    cv2.destroyAllWindows()

while True:
        vidcapt()


clip1 = VideoFileClip("11,05,42.avi")
clip2 = VideoFileClip("11,05,47.avi").subclip(50,60)
final_clip = concatenate_videoclips([clip1,clip2])
final_clip.write_videofile("merged.avi")

• FFMPEG - stream download + resize + HVEC convert in one statement ?

  6 mars 2021, par Armitage2k

  I have a collection of 30 to 60 minutes PORTRAIT videos which I download via the below ffmpeg statement. That part works fine, but given that the resolution of the videos is quite high, it results in approx. 1,3 GB mp4 files.

  


  Once downloaded, I usually convert the video to 720p resolution which brings it down to approx. 500 MB per video, and then run another HVEC x265 compression which alas results in 250MB - 350MB sizes.

  


  Since its quite tedious to do all this manually, I was wondering if there is a FFMPEG statement / command I can use that achieves all of this in one go while downloading ?

  


  Below the commands I currently use.

  


  Thank you
