• FFmpeg error when trying to stream file into it

  15 décembre 2015, par nadermx

  I’m trying to put a stream into a ffmpeg pipe.

  The issue I am having is that when I send the data to ffmpeg I get a error 127

  It also shows /bin/sh: 2: -acodec: not found

  Here is the console log I’m running via python

  from subprocess import Popen, PIPE
  
  from flask import Flask, stream_with_context, request, Response
  
  from signal import signal, SIGPIPE, SIG_DFL
  
  signal(SIGPIPE,SIG_DFL)
  
  
  
  def console(cmd, add_newlines=False):
  
      p = Popen(cmd, shell=True, stdout=PIPE)
  
      while True:
  
          data = p.stdout.read()
  
          if add_newlines:
  
              data += '\n'
  
          yield data
  
  
  
          p.poll();
  
          if isinstance(p.returncode, int):
  
              if p.returncode > 0:
  
                  # return code was non zero, an error?
  
                  print 'error:', p.returncode
  
  
  
              break
  
  
  
          sleep(2)

  And here is the actual route I am running the application in.

  @app.route('/large.mp3')
  
  def generate_large_mp3():
  
      url = 'https://www.youtube.com/watch?v=zGEiJ44K3Oo'
  
      result = ''.join(data.strip() for data in console('youtube-dl --simulate --get-url %s' % url))
  
      mp3 = console('sudo ffmpeg -i %s -acodec libmp3lame  -f mp3 -' % result, add_newlines=True)
  
  
  
      return Response(stream_with_context(mp3), mimetype='video/mp3')

  Here is the error output

• FFmpeg error : ratecontrol_init : can't open stats file

  18 décembre 2015, par oldo.nicho

  I’ve setup an AWS EC2 instance running Ubuntu 14.04 and have installed FFmpeg so that I can compress and transcode video.

  I’m trying to do a two pass conversion with the following code :

  ffmpeg -i input-file.avi -codec:v libx264 -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=702:-1 -threads 0 -pass 1 -an -f mp4 ~/encoded/null

  and second pass :

  ffmpeg -i input-file.avi -codec:v libx264 -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=702:-1 -threads 0 -pass 2 -codec:a libfdk_aac -b:a 128k -f mp4 output-file.mp4

  However I get the following error :

  The command as written above works fine on my local computer (running OSX). Would anyone have any suggestions as to how to fix this problem ?
