LibrePlanet 2014 stream recordings

Published on Sun 23 March 2014. Filed under . Tags .

The LibrePlanet 2014 conference talks end today. Since there are no official recordings yet, several users published copies of fragments of the live streams that they have downloaded. This page lists the fragments that I know.

Since these are only fragments of live stream downloaded using a faulty script, many are incomplete and some are impossible to watch. I haven’t found slides files for other talks; if the recording shows slides, I’ve listed it above.

I don’t know what copyright licenses apply to the recordings: the conference site lists Creative Commons Attribution-ShareAlike 3.0 US for videos, while I don’t believe some speakers would agree to use a free license for their recordings, so I don’t trust this information.

Lessons learned from using wget to download the streams

I believed I knew how to download files via HTTP using the wget program. I was mistaken:

  • wget -c corrupts the file instead of resuming it
  • retry on timeout corrupts the file

I used wget in a loop with some delay between retries to download the stream to another file after a part ended. Since the streams are live and different at each time, the commonly used logic for resuming overwrote earlier parts of the streams.

Why there is no standard and supported way to make HTTP servers inform the client that each download gets a different document that shouldn’t be downloaded to the same file?

Watching the talks

I used mpv to watch the downloaded files. The media player program that I usually use, VLC, did not handle them properly.

I hope the FSF will release real and complete recordings on their GNU MediaGoblin instance, so these stream copies won’t be needed.
