Subject: [downloader/fragment] Make speed more smooth
X-Git-Url: https://git.cielonegro.org/gitweb.cgi?a=commitdiff_plain;h=1b5284b13f1b579b2cbac5ce6ab9faa5b95800fb;p=youtube-dl.git

[downloader/fragment] Make speed more smooth

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.
