Are you trying to download http://www.ustream.tv/recorded/86423931? It works now:

Closing as it looks like a temporary UStream server-side issue. Please paste the full verbose log (not omitting anything) if the problem persists.

Yes, I can download it now, but it has been an intermittent issue several days ago (but I could nevertheless watch it in browser, so IMHO there had to be a way for yt-dl to download it). Anyway, even if this is a server side failure, maybe it would deserve a better reaction on the side of yt-dl instead of just a stacktrace.

I see. Please leave a comment if the problem appears again.

I has been working great several days in a row, but now failed again.

youtube-dl --verbose --write-pages http://www.ustream.tv/channel/sauces-cam 2>&1 | tee _log

zip -r youtube-dl--sauces-cam--failure.zip youtube-dl--sauces-cam--failure

youtube-dl--sauces-cam--failure.zip

P.S. This may or may not be related: after I have started playback in the browser and waited for the annoying ads to finish, youtube-dl has successfully started its download.
