• python/flask ffmpeg m3u8 download

  17 mai 2017, par kittencornball

  I got ffmpeg working in the command line/app.py just fine with

  os.popen("ffmpeg -i LIVESTREAMURL -c copy thevideo.MP4")

  the end goal is to have this running on a site so i can just plop the m3u8 live stream in and download the video in a mp4 format

  heres what ive tried on my heroku app

  from flask import Flask
  
  from flask import send_file
  
  app = Flask(__name__)
  
  import os
  
  import subprocess
  
  import ffmpy
  
  
  
  
  
  farts = os.popen("ffmpeg -i LIVESTREAMURL -c copy thevideo.ts")
  
  
  
  @app.route("/")
  
  def hello():
  
      return "Hello World!"
  
      return farts

• ffmpeg drawtext to overlay text repeatedly over the whole video space

  5 avril 2022, par Osama Bin Saleem

  I want a specific text like Hello world to be spread across multiple rows and over the whole video space/page like this.


  


  I'm running ffmpeg commands in the python script using bash as a subprocess. Sample code :

  


  


  subprocess.run(
[
"ffmpeg",
"-i",
input_file,
"-vf",
f"drawtext=font=font_family:text=watermark_text:fontcolor=font_color:fontsize=font_sizebackground_box :watermark_position",
"-codec:a",
"copy",
"-preset",
encoding_preset,
f"./watermark/media_id.mp4",
]
)

  


  


  Is there any good way to achieve this ?

  


• Virtual host compared to multiple servers

  9 septembre 2011, par josiecat

  This may be dumb but has me wondering why and I know how to setup the virtual host but need to know the why or what it is good for.

  Why do you setup virtual host for local development and why not just put sub directories ?

  What are the real world uses and how do you use virtual host ?

  (my normal set up as of now)
  I use Mamp and just put more folders (speaking dummy terms here) in the htdocs folder. Is that ok what am I missing ?

  The reason why I would like to use virtual hosting is because I would like to have a few servers to try different technologies (e.g. adding ffmpeg support for streaming video and many others ) but do I use virtual hosting to be able to have more than one server or do I need to use something like virtual machine to have multiple servers with different versions of PHP, Mysql etc...?

  I understand how to set this stuff up just don't understand the difference from virtual host to multiple servers ? could I actually set up one with php just the basic and another for php with ffmpeg-php and other stuff like zend or what ever just to have different server environments to basically mock the actual server that the project will land when done ?
