• Python - ffmpeg-like media seeking with requests

  8 janvier 2017, par Will

  Using ffmpeg, times in HTTP media resources, such as videos, can be seeked to very quickly with a command like ffmpeg -ss 00:01:00 -i https://example.com/video.mp4, presumably by downloading the video headers to look for the right byte offset. This means that it is very fast to run operations on a section of video, even if it is hours in.

  What I want to be able to do is to do the same thing but piping into ffmpeg with the requests module with something like (in partial pseudo-code) :

  stream = requests.get(url, stream=True)
  
  start_byte = get_byte_offset(stream, time=60)
  
  stream.seek_to(start_byte)
  
  
  
  process = subprocess.Popen(["ffmpeg", "-i" "pipe:" "out.mp4"], stdin=subprocess.PIPE)
  
  
  
  for chunk in stream.iter_content(chunk_size=64 * 2 ** 10):
  
      process.stdin.write(chunk)
  
  process.stdin.close()

  This would allow me to implement extra checks into the stream that I would normally need to parse ffmpeg for, such as if the stream returns a bad status code such as 404 or 403.

  How might I be able to implement this using the requests, and presumably other, modules ? I suppose the first part is using a tool to parse the video headers.
