• KeyError : 'video_fps' with moviepy ffmpeg

  11 août 2020, par Ethan Shoe

  I am writing a Python script to convert a video (.MP4) into an audio file (.MP3) on a Django server. To achieve this, I am using the Moviepy library but when I run the script, I get the following error :

  



  Internal Server Error: /test/

  There's practically no information about this error or how to solve it that I could find, so any help or insight would be much appreciated.

  



  Here is my Python script (views.py) :

  



  import pyodbc, json, pytube
from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt
from rest_framework import parsers
import os
from moviepy.editor import *

def test(request):

    filePath = 'C:\\Users\\etsho\\Music\\'

    #retrieve url from app
    body_unicode = request.body.decode('utf-8')
    body = json.loads(body_unicode)
    videoURL = body['url']

    print("before download")

    #download youtube video
    youtube = pytube.YouTube(videoURL)
    videoTitle = youtube.title
    video = youtube.streams.filter(only_audio=True).first()
    freshDownload = video.download(filePath)

    print("after download")

    basePath, extension = os.path.splitext(freshDownload)
    video = VideoFileClip(os.path.join(basePath + ".mp4"))
    video.audio.write_audiofile(os.path.join(basePath + ".mp3"))

    print("video converted")



return HttpResponse("")


  


• Whatsapp FFMPEG thumbnail is not showing

  7 avril 2020, par Youssof H.

  I want to run a command that will add an image as a thumbnail to a video. The video will be shared by WhatsApp with a thumbnail showing up.

  



  The problem is that after running the following command thumbnails don't show up in Whatsapp though it shows on Windows 10.

  



  ffmpeg -i path/to/Video.mp4 -i path/to/Video.png -map 0 -map 1 -c copy -c:v:1 png -disposition:v:1 attached_pic -strict -2 path/to/out.mp4


  



  And another problem is that the video with a thumbnail doesn't play on Android, iPhone, Windows, nor on Linux.

  What am I doing wrong ?

  



  Note : It's okay if it works with python.

  


• Conditionally rotate portrait video if landscape with FFmeg

  12 novembre 2019, par Jules

  I need to convert only portrait videos to landscape, some video maybe landscape already.

  I need to achieve this with a shell script on a mac.

  I’ve previously managed to rotate a video with ..

  ffmpeg -i "/Users/jm/Library/Mobile Documents/com~apple~QuickTimePlayerX/Documents/output.mp4" 
  
  -strict 1 -metadata:s:v rotate="90" -codec copy "$3"

  $3 is the input file in my shell script

  I’ve found this ...

  ffmpeg -i input.m4v 2>&1 | grep rotate

  From this answer https://stackoverflow.com/a/31683689/450456

  I’m not sure how to combine the two, or have to get and use the height and width in an if statement in a shell script.
