The Norwegian nationwide open +channel Frikanalen is still going +strong. It allow everyone to send the video they want on national +television. It is a TV station administrated completely using a web +browser, running only Free Software, and with distribution on the +national DVB-T distribution network RiksTV. But only between 12:00 +and 17:30. This has changed. A few weeks ago, we set up a Ogg Theora +stream via icecast to allow everyone with Internet access to check out +the channel the rest of the day. This is presented on +the Frikanalen web site now. And +since a few days ago, the channel is also available +via multicast on +UNINETT, available for those using IPTV TVs and set-top boxes in +the Norwegian National Research and Education network.

+ +

If you want to see what is on the channel, point your media player +to one of these sources. The first should work with most players and +browsers, while as far as I know, the multicast UDP stream only work +with VLC.

+ + + +

The Ogg Theora / icecast stream is not working well, as the video +and audio is slightly out of sync. We have not been able to figure +out how to fix it. It is generated by recoding a internal MPEG +transport stream with MPEG4 coded video (ie H.264) to Ogg Theora / +Vorbis, and the result is less then stellar. If you have ideas how to +fix it, please let us know on frikanalen (at) nuug.no. We currently +use this with ffmpeg2theora 0.29:

+ +
+./ffmpeg2theora.linux <OBE_gemini_URL.ts> -F 25 -x 720 -y 405 \
+ --deinterlace --inputfps 25 -c 1 -H 48000 --keyint 8 --buf-delay 100 \
+ --nosync -V 700 -o - | oggfwd video.nuug.no 8000 <pw> /frikanalen.ogv
+
+ +

If you get the multicast UDP stream working, please let me know, as +I am curious how far the multicast stream reach. It do not make it to +my home network, nor any other commercially available network in +Norway that I am aware of.
