FSIJ join to Software Freedom Day

We, FSIJ join to Software Freedom Day 2012. Japanese Wiki page had publishd by Nobuhiro Iwamatsu, a developer of Debian Project.

I prepared to broadcast the event by 100% Free Software, I can get many suggestion by the last article comments, thank you. The following is my recipie:

ffmpeg -s 320×240 -f video4linux2 -i /dev/video0 -b 128k \
-f alsa -ac 2 -i hw:0,0 -acodec vorbis -vcodec libtheora -r 25 -f ogg -\
|oggfwd host.example 8000 passwd /test.ogv

 

How do I broadcast video streaming with Free Software?

I, as a member of FSIJ, consider to broadcast a Software Freedome Day in Japan. In the past, I can do it with gstreamer and icecast2 in The 5th International GPLv3 Conference. Howerver, gstreamer command is very complex and the Interface had changed, so I can’t re-do it by my old script.

Usteram is easy to use, but it is not Free Software. I could find such packages in Debian repos:

I’ll try to use them and to find the good tool.

Update 2013/12/16

I had got a mail to use xiph’s vorbis encoder instead of ffmpeg internal vorbis encoder:

ffmpeg -s 320×240 -f video4linux2 -i /dev/video0 -b 128k \
-f alsa -ac 2 -i hw:0,0 -acodec libvorbis -vcodec libtheora -r 25 -f ogg -\
|oggfwd host.example 8000 passwd /test.ogv

The different is “-acodec libvorbis” option. Thank you for the information.
