OK, so now all links from http://www.ripe.net/ripe/meetings/ripe-46/webcast.html are not working for me. The IPv6 link appears to connect but bombs out while 'buffering'. Is anyone succesfully connected at the moment?

mplayer doesn't know the audio codec used (0xA)
by Boudewijn Visser 03 Sep '03

03 Sep '03

Hello RIPE Webcast people, I've tried to view the sessions being webcasted, and a problem. The audio codec used is not supported by mplayer, and I haven't been able to locate any other open source program capable of playing these streams. Mplayers identified the audio stream as follows : ======= WAVE Format ======= Format Tag: 10 (0xA) Channels: 1 Samplerate: 8000 avg byte/sec: 1000 Block align: 300 bits/sample: 16 [..] Cannot find codec for audio format 0xA A fairly extensive google search for the problem finds a few people who have the same problem, but no solutions. Checking the mplayer sources ( mplayer-1.0pre1 , latest release) shows that this codec/format is indeed unknown. I'd appreciate it if you could change the codec to either plain PCM, or MP3, for example. (Actually, what -is- the codec used at the moment ? ) Unless I missed something perhaps, in which case I hope you can provide a few pointers on how to use mplayer (or any other free unix tool ) to view and listen to the webcasts. ----- Apart from this problem though, I'd hope that RIPE would use non-propietary formats in general as much as possible. Regards, Boudewijn Visser

Audio under linux based players
by Mally Mclane 03 Sep '03

03 Sep '03

Dear Colleagues, As many of you have noticed, we currently have a problem where the audio we are encoding into, cannot be heard under (generally) linux based players, as no codec exists. Unfortunately at this present time we have been unable to find a solution to this, and we apologise unreservedly for something we should have foreseen. We will keep trying to find a solution (pointers/suggestions welcome!) during this week and after RIPE46 has finished, we will redouble our efforts to find such a solution. Once we find a solution, we will re-encode the archives that are being made of our sessions. Again, apologies for you not being able to hear the audio at this time and thanks for your interest! Regards, Mally Mclane RIPE NCC - Operations

Linux / Unix client for Webcasting
by Jarno Lähteenmäki 03 Sep '03

03 Sep '03

Hi, I used the VideoLan client (www.videolan.org) instead of MPlayer. I found it much more rich featured. It can turn unicast stream into multicast or vice versa. It can record into hard-drive. It supports also almost any known OS. --> Jarno Lähteenmäki

I'm trying to view the transmission using MPlayer. The video is working as expected, but I cannot decode the audio stream: Cannot find codec for audio format 0xA. Do you have any idea how to get the audio with MPlayer? I'm using Debian Woody with the stable mplayer-686 and the full w32codecs packages from Marillat.

Players for Windows Media are on most versions of Windows, OS/X and Linux. Unfortunately, we're still on unicast for this meeting, but one of our mirrors is very kindly offering the stream over IPv6. Our list of mirrors is: RIPE Attendees Only: mms://webcast.ripemtg.ripe.net/ripemtg Spain Mirror: mms://media.rediris.es/ripemtg Portugal Mirror: mms://wms.fccn.pt/ripemtg and http://wms.fccn.pt/ripemtg Denmark Mirror: mms://130.225.243.26/ripemtg Czech Republic Mirror: mms://server1.streaming.cesnet.cz/ripemtg and IPv6 mms://server6.streaming.cesnet.cz/ripemtg United Kingdom Mirror: mms://ccs-web2k.brynmill.swan.ac.uk/ripemtg or mms://ccs-web2k.brynmill.swan.ac.uk/ripe (?)

We are experimenting with providing an additional audio-only stream, and it may be possible to listen to DN* 2 & 3 in near-realtime. Please check the webcast page for further details at the time ). Friday: 09:00 - 10:30 - Plenary Part 3 11:00 - 12:30 - Plenary Part 4 ( Please note that although the RIPE NCC Annual General Meeting is being held on Friday afternoon in the same venue as the RIPE meeting, it NOT be webcast as it is not a part of the RIPE meeting. ) An archive of each session should be available within 15 minutes of the actual conclusion of the session (noting here that some sessions do have a tendency to run overtime). Please remember to check the webcast archive page for when each archive is available, as local circumstances may delay the provision of the archives (such as the bandwidth from the meeting venue). If you have problems with the stream during the official times of the streaming listed above, or accessing the archived sessions, please do not hesitate to contact RIPE NCC Operations at ops(a)ripe.net, or indeed, this list. We will endeavour to resolve the problem as soon as possible. Regards, -- Bruce Campbell RIPE Systems/Network Engineer NCC www.ripe.net - PGP562C8B1B Operations/Security

IPv6 Webcast

Hello, I've noticed today that CEZNET is providing a streaming server (RIPE-46 sessions) with IPv6: + server6.streaming.cesnet.cz + 2001:718:1:7:230:48ff:fe42:30de + traceroute6 is OK from here (11 hops) + ping6 is OK from here (55 avg rtt) However, im failing to see the session using version 9.00.00.3008 of MediaPlayer and VideoLan 0.5.2 under WinXP (and it works fine on the v4 streaming servers with both clients...) Has anybody tried this v6 server? Can anybody give me an hint on this? Thanks in advance.

Hello, I think it can be very valuable to place info about webcasting ho RIPE homepage. I think it grows the audience of the webcast more than three times. Regards Michal
