Body: <p>hi im trying to insert for loop results in a ffmpeg command i tried some code but all i get is first text with no sound and it glitches and freezes i tried many modification but no success i appreciate if you have any ideas that would be great, the imported text from api should display only the duration of audio file here is my code:</p>
  <pre><code>
  import requests
  import json
  import os
  import requests
  import http.client
  import io
  import subprocess
  
  
  response = requests.get('http://api.quran.com:3000/api/v3/chapters/2/verses?text_type=image&amp;language=ar&amp;recitation=10')
  
  json = json.loads(response.content)
  
  data= json['verses']
  #print(data)
  
  for i in data:
      input_text = i['text_madani'] 
      input_duration = i['audio']['duration'] 
      input_mp3 = i['audio']['url']
      input_img = i['image']['url']
   #   print(input_duration)
      command = f'''ffmpeg -re -stream_loop -1 \
                      -i img2.jpeg \
                      -i {input_mp3} \
                      -vf 'pad=ceil(iw/2)*2:ceil(ih/2)*2,drawtext=enable='between(t, n, {input_duration})':text={input_text}:fontsize=90:x=50:y=50:fontcolor=black@0.8' \
                      -c:v libx264 -preset veryfast -b:v 3000k \
                      -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 \
                      -c:a aac -b:a 160k \
                      -ac 2 -ar 44100 \
                      -y -f flv rtmp://localhost/hls/test''' 
      print(command)
      os.system(command)

Comments.Text: minor nitpick. If you're executing ffmpeg on the command line like you are, you don't need to import ffmpeg from your code.
