• Ubuntu 16.04 python installing 3rd party module ffmpeg-3.0.2

  3 juin 2016, par vanoccupanther

  Have tried installing this package multiple times. Initially I installed it to a directory where I am running scripts that call it but I get an error message "ImportError : No module named ’ffmpeg’".

  I then tried putting it in one of my python paths listed in sys.path and again I got the same message.

  I then opened .bashrc and added the home directory path and still got the same error message when I ran my script.

  import sys
  
  import pandas as pd
  
  import numpy as np
  
  import matplotlib.pyplot as plt
  
  import ffmpeg
  
  
  
  from PIL import Image
  
  
  
  img = sys.argv[1] # ignore this
  
  
  
  im = Image.open(img) # ignore this
  
  imarray = np.array(im) # ignore this
  
  
  
  ffmpeg -i ('flame.avi') -f image2 -c:v mjpeg ('image-%d.jpg')
  
  avconv -i ('flame.avi') -vsync ('1') -r ('100') ('image%03d.tif')

  I’m really not sure where to go, what are my options here ? And what am I doing that is glaringly wrong ?

• FFMPEG - live stream with dynamic content

  6 octobre 2019, par Arturek

  I’m trying to create a live stream with changing data in real-time on youtube.

  Let’s say I want to show the current Bitcoin price in real-time. For instance, using python and sending requests to some public APIs, I can very easily get current prices of Bitcoin. But I have no idea how to create such a live stream, which will be automatically updated with fresh data.

  I know that I can use ffmpeg to stream on youtube, but how would I change the content of my stream ? I know how to create an image every n seconds with the current price, but then I don’t know how to update my live stream with this image.

  # To make sure you know what I mean, I created a basic sample.
  
  
  
  import requests
  
  import json
  
  import time
  
  
  
  createYtLiveStream()
  
  
  
  while(True):
  
    response = requests.get('https://api.coindesk.com/v1/bpi/currentprice.json').json()
  
    price = response['bpi']['USD']['rate']
  
  
  
    # Create an image with Bitcoin price inside
  
    img = convertTextToPng(price)
  
  
  
    # Update my live stream with this new image (I don't know how to do it)
  
    updateYtLiveStream(img)
  
  
  
    time.sleep(20)

  I want to do it on Ubuntu. Can you tell me how can I do it, please ?
  Thanks.
