KeyError: u'total_bytes'

• I've verified and I assure that I'm running youtube-dl 2016.09.04.1 (latest codebase)
• At least skimmed through README and most notably FAQ and BUGS sections
• Searched the bugtracker for similar issues including closed ones

What is the purpose of your issue?

• Bug report (encountered problems with youtube-dl)
• Site support request (request for adding support for a new site)
• Feature request (request for a new functionality)
• Question
• Other

When using this python code:

from __future__ import unicode_literals
from youtube_dl import YoutubeDL

id = 'VxEgGUBaXw4'
audiofmt = '141/172/140/171/139'
videofmt = '137/248/299/303'
tmploc='/var/ytdl_tmp/'

def size_human(num):
    for x in ['bytes','KB','MB','GB','TB']:
        if num < 1024.0:
            return "%3.1f %s" % (num, x)
        num /= 1024.0

def progress_hook_video(pr):
    if pr['status']=='finished':
        pass
    else:
        prgstr = 'Getting Video ' + str(round(pr['downloaded_bytes'] / (pr['total_bytes'] / 100))) + '% (' + size_human(pr['downloaded_bytes']) + '/' + size_human(pr['total_bytes']) + ')'

ydl_options = {
    'outtmpl': tmploc + '%(id)s.video',
    'continuedl': True,
    'format': videofmt,
    'cache-dir':'/var/www/.cache/youtube-dl',
    'fixup':'warn',
    }

with YoutubeDL(ydl_options) as ydl:
    ydl.add_default_info_extractors()
    ydl.add_progress_hook(progress_hook_video)
    ydl.download([id])

I get this error:

KeyError: u'total_bytes'

This does not errors with all videos but a few like VxEgGUBaXw4 in this example.

For fragment-based formats like DASH, there's no total_bytes. Use total_bytes_estimate instead.
