YouTube may often return 404 HTTP error for a fragment causing the
whole download to fail. However if the same fragment is immediately
retried with the same request data this usually succeeds (1-2 attemps
is usually enough) thus allowing to download the whole file successfully.
So, we will retry all fragments that fail with 404 HTTP error for now.
At the beginning of every segment there was a drop to Unknown speed due to timeslice being too small to calculate speed.
Now last speed from the previous fragment is used.
When using the mpegts container hls vidoes can be played while being downloaded (useful if you are recording a live stream).
VLC and mpv play them file, but QuickTime doesn't.
In some dailymotion videos (like http://www.dailymotion.com/video/x3k0dtv from #8156) the segments URLs don't have the 'Content-Length' header and HttpFD sets the 'totat_bytes' field to None, so we also use '0' in that case (since we do different math operations with it).
If you run 'while read aurl ; do youtube-dl "${aurl}"; done < path_to_batch_file' (batch_file contains one url per line that uses the hls downloader) each call to youtube-dl consumed some characters and 'read' would assing to 'aurl' a non valid url
(This is the same problem that was fixed for the ffmpeg postprocessors in cffcbc02de)
