• HTTP Livestreaming with ffmpeg

  25 août 2016, par Hugo14453

  Some context : I have an MKV file, I am attempting to stream it to http://localhost:8090/test.flv as an flv file.

  The stream begins and then immediately ends.

  The command I am using is :

  sudo ffmpeg -re -i input.mkv -c:v libx264 -maxrate 1000k -bufsize 2000k -an -bsf:v h264_mp4toannexb -g 50 http://localhost:8090/test.flv

  A breakdown of what I believe these options do incase this post becomes useful for someone else :

  sudo

  Run as root

  ffmpeg

  The stream command thingy

  -re

  Stream in real-time

  -i input.mkv

  Input option and path to input file

  -c:v libx264

  Use codec libx264 for conversion

  -maxrate 1000k -bufsize 2000k

  No idea, some options for conversion, seems to help

  -an -bsf:v h264_mp4toannexb

  Audio options I think, not sure really. Also seems to help

  -g 50

  Still no idea, maybe frame rateframerateframerateframerate ?

  http://localhost:8090/test.flv

  Output using http protocol to localhost on port 8090 as a file called test.flv

  Anyway the actual issue I have is that it begins to stream for about a second and then immediately ends.

  The mpeg command result :

• how can I get the length of an video in order to validate django form before upload can begin ?

  10 juillet 2013, par GetItDone

  I have an app running on heroku that allows users to upload videos, then I use ffmpeg to preform 3 tasks using celery and redis-to-go :

  1) Check the format and if it isn't already mp4, convert it to mp4.
  
  2) Extract a 3 minute clip, in mp4 format
  
  3) Grab an image from the video

  The problem is that I want to verify the video length before the video is uploaded and the three tasks are run since I want to make sure all videos are at least 15 minutes, and if not I want to raise a ValidationError. So when validating the form, I want to do something like this :

  def clean(self, *args, **kwargs):        
  
      data = super(ContentTypeRestrictedVideoField, self).clean(*args, **kwargs)
  
  
  
      file = data.file
  
      try:
  
          content_type = file.content_type
  
          main, extension = content_type.split('/')
  
          if content_type in self.content_types:
  
              if file._size > self.max_upload_size:
  
                  raise forms.ValidationError(_('Please keep filesize under %s. Current filesize %s') % (filesizeformat(self.max_upload_size), filesizeformat(file._size)))
  
              if VIDEO_LENGTH < MINIMUM_LENGTH:
  
                  raise forms.ValidationError(_('Please make sure video file is at least %s. Current video length %s') % (MINIMUM_LENGTH, VIDEO_LENGTH)
  
          else:
  
              raise forms.ValidationError(_('File type is not supported. File must be mov, flv, avi, mpeg, wmv, or mp4.'))
  
      except AttributeError:
  
          pass        
  
  
  
      return data

  What could I do for VIDEO_LENGTH and MINIMUM_LENGTH ? I read that ffprobe could be used for getting the duration, but it isn't available with the buildpack I am using and I am very inexperienced. I can't just validate file size because it can vary greatly depending on numerous factors. Anyone have any solution as to what I could try ? Thanks
