Oh yes, it took a while. But we finally managed to finalize the 22C3 audio and video recordings and to provide them via a podcast feed as well.
We now provide audio recordings in MP3, MPEG-4 Audio and Ogg Vorbis format and videos in MPEG-4 AVC (H.264) 320×240 format in addition to our originally posted full resolution MPEG-4 versions. The new videos run on the iPod and are around 25% the size of the big files.
To make the material easily accessible, you can subscribe to the main podcasts feeds for either audio or video or just download the files directly from these web pages:
We’d love to hear from you what you think about the content being offered using podcast technology.
As a convenience, we also provide podcast feeds for the Ogg Vorbis and the MPEG-4 AAC audio versions. These are considered to be experimental. Drop a comment if you think if the podcast in general or these alternative versions are useful for you.
All podcasts are hosted by the Chaosradio website which is also our central point for CCC’s audio and video podcast content including recordings from other CCC events as well.
All recorded 22C3 videos are online now (via BitTorrent and HTTP). Get the individual torrent files or get all torrent files in one tar.gz archive: 22C3-videos-complete-20050506.tar.gz (here are the checksums).
We still plan to provide complete torrent sets and extra torrent sets optimized for DVD-sized download chunks so that it is easier to archive that stuff. We are a bit distracted by other stuff currently, but we will bring you an update soon. Audio-only versions will follow soon as will the iPod-versions.
If you want to mirror the content, please use BitTorrent to get the files and publish your server address in the Wiki. All mirrors are welcome. Please make sure you keep track of the final updates by subscribing to this blog.
Update: We have now updated our archive to include all 140 recorded events. Please use the new links above to get the additional stuff. Recordings for these events have been added: Personal experiences bringing technology and new media to disaster areas, Bluetooth Hacking – The State of The Art , Elektronische Gesundheitskarte und Gesundheitstelematik – 1984 reloaded?, Die Technik im neuen ePass, Biometrics in Science Fiction and Black Ops Of TCP/IP 2005.5.
We are coming along well. The recordings are on the server now and we are creating .torrent files now. Once ready, we will publish them so that you can use BitTorrent to download them. Once we feel that the first run is over, we will open direct HTTP access to the files. If we would do this from the beginning, I am sure the server wouldn’t survive it.
So now that we are able to give you what you want, there is something we want from you:
PLEASE PROVIDE FEEDBACK ON THE LECTURES!
USE THE FEEDBACK FORMS!
Each event has it’s own unique feedback URL, easily accessible on each event’s web page in our 22C3 Fahrplan. So it shouldn’t be too hard to locate the proper resource.
For instance, if you just seen the recently posted video of our 22C3 Opening Event, why not go ahead and give us feedback on this on the corresponding feedback page? Oh, that easy? Yes. That easy.
Apart from the rating, please also leave an opinion on the lecture as well. This doesn’t have to be much, just speak your mind and let us know what you think.
This whole feedback business is very helpful for us in determining what was okay and what went wrong. So please take your time and tell us what you think. Thank you.
I uploaded the first official 22C3 video recording: it’s the recording of the opening speech and keynote. Unfortunately, the video quality itself is not good as this is one of the recordings that had to be recovered from the failed realtime recordings. Most other videos will be much better. Here it is:
22C3-390-en-private_investigations.mp4 (MPEG-4, 1.2 MBit/s)
A few notes on the format: this is a standard MPEG-4 encoded (audio and video) file in a standard MP4 container file. The native resolution is 720×576 pixels but as this is derived from video, it is a non-square pixel format. The file has the proper bit set (the so-called PAR or SAR bit) to reflect this property. Your video player should honor this bit and scale the video on playback, effectively extending the displayed area to 785×576 pixels.
We would be happy if you could download the file and post success or failure of playback as a comment to this post so that we know we are safe (or not). We will post the rest of the videos once we are sure everything is fine.
Sorry again for all the delay. We will spend another post on what we had to go through to make these works available.
We just released the “2.0” update to the 22C3 Fahrplan which now includes most lecture materials (excluding just a few slides by some lazy speakers). There will be some minor updates in the coming days to add the remaining stuff and another update to point to the recordings once the audio and video files are online.
Okay. Good news on the horizon. All videos are collected, a naming scheme is defined and we have sorted out our formats. The encoding machines are ready to run. And will be started any moment.
To give you the chance for some final checking, we have put up some samples for the various formats for you to test. So if you are technically inclined you might want to check them out in terms of quality and compatibility. The sample is always the same two minute clip.
- MPEG-4 H.264 320×240 iPod Video compatible (MPEG-4 H.264 Baseline Profile Video, MPEG-4 AAC Audio, MP4 Container, 0,23 MBit/s)
- MPEG-4 720×576 (MPEG-4 Video, MPEG-4 AAC Audio, MP4 Container, 1.2 MBit/s)
- Windows Media 9 Standard 720×576 (WMV9 Audio/Video, WMV Container, 1.9 MBit/s)
- MPEG-2 720×576 (MPEG-2 Muxed Audio/Video, VOB Container, 6 MBit/s)
Take your pick and feel free to comment here.
“…it’ll probably be only days away.”
More infos from the people working on them here.
Dear English-speaking readers of this blog: The remainder of this post is in German. Sorry for that, but the podcast featured is in German as well.
Aus unerfindlichen Gründen haben wir den Podcast Chaosradio Express hier noch nie erwähnt. Vor dem 22c3 gab es einige Sendungen, die sich mit dem Congress und seinen Vorbereitungen beschäftigt haben. Letzte Woche gab es dann den Chaosradio Express 014 (mp3, website), der auf den vergangenen 22. Chaos Communication Congress zurückblickt. Im Gespräch lassen Tim Pritlove und Jens Ohlig ausgewählte Vorträge und Präsentationen des Congress Revue passieren. Im Anschluß werden zahlreiche interessante Konferenzen und Workshop-Treffen im kommenden Jahr vorgestellt. Vergessen wurden im CRE014 leider die Datenspuren im Mai 2006.
CRE014: 22C3 Rückblick, Veranstaltungen in 2006 (mp3)
There has been some confusion regarding the AV recordings and slides of the 22C3 lectures. So let us explain what is coming and that everything will be fine.
The good news is: everything has been recorded! Yes, we have had our accidents but the fallback systems have worked so nothing is lost. As quite a few recordings have to be recovered from tape, the whole process will take a while but we are confident that we can deliver what everybody wants by the end of January.
More confusion has been generated as a couple of recordings have been available in WMV format up front which made many people believe it is our intention to provide everything in WMV only. This is not the case. The truth is that this has been just an additional service that was not related to the main documentation process.
So everything will be cool. Every single lecture will be available in the following video formats:
- MPEG-2 (5 MBit/s)
- MPEG-4 (1.2 MBit/s Simple Profile)
- WMV (250 KBit/s)
In addition, all lectures will come in audio-only versions also in MP3 and OGG format in reasonable bitrates. All video and audio recordings will be licensed under the Creative Commons Attribution-NonCommercial-NoDerivs 2.0 Germany license.
And yes: we’ll make sure the MPEG-4 version will run on the iPod. There might be a iPod-compatible MPEG-4 H.264 768 KBit/s version as well in the near future. We’ll see what we can do.
Another idea is to provide the lectures in original order in a podcast that releases a lecture a day (or so). If you think this is a good idea voice your support by dropping a comment here.
The slides will be available on the event description pages in our Fahrplan as soon as they are available. Most of the stuff is already there and as long as all speakers will send us their slides, we will publish it. If you are a speaker and you haven’t sent us the slides, please do so.
This is going to be the best documented C3 ever. We are very happy about this.
