The videos from ICML 2011 are now online, however, I have a hard time viewing them, despite having a good connection on my end. The video stops, while the audio keeps going, then both stop ad nauseum.

Is there any way to download the raw videos for offline viewing? Firefox's Downloadhelper isn't working for these.

I much preferred videlectures.net - at least you could save the video stream with "mplayer -dumpstream", although Youtube probably would've been better.

Thanks!

P.S. Is that web site working reasonably for anyone else?

I'm at work so I can't test directly - but do they buffer? Start playing, then pause the video. Come back a while later and it should have loaded most of it.

Robert, thanks for the suggestion. I tried this but the video is still very jittery (as if it's 0.2 FPS).

You should be able to use rtmpdump to download the stream. There is an RTMP url if you view the source of the talks.

I tried rtmpdump about a week ago and ultimately gave up. I got the impression that the servlet for techtalks doesn't correctly use the rtmp protocol based on what wireshark was showing me.

Alexandre, thanks a bunch!

Brian, try [mplayer -fs -dumpstream "rtmp://....flv" -dumpfile dest.flv]

With rtmpdump, you also need [ -y /edited/etc.flv] (the manual is unhelpful)

When downloading the slides, rtmpdump loops forever, it seems. The video I'm looking at is still weird, but the audio is OK. The slides are useless (only the first 2 minutes)

I hope ICML changes its mind and uploads the videos somewhere better.

Agreed. The videolectures.net format was far better.
