Steam: get thumbnails
TED: get thumbnails
Decode the data requested to the api in utf-8.
Message for delete video it's not an error.

When using youtube-dl from another python script with the quiet option
on, and a post procesor for extract the audio. The message of deleting
video shows in the first script logs (as it goes to stderr).

There is no way to keep this quiet as it's treated as an error, even if,
for me, it's not.
