sorry, i was unprecise. the commandlines i used were much longer and
also captured and piped audio.
what i tried:
mplayer tv:// -tv driver=v4l:device=/dev/video1:width=320:height=240:fps
-ao pcm=pipe.wav \
and on the other side of the pipe:
theora_encoder_example pipe.wav pipe.yuv \
| oggfwd domain.org 8010 password /video.ogg
this didn't work. your post suggested to try it without audio and it
works well. piping works fine with one pipe only. but that doesn't solve
my initial problem: i'd like to capture audio and video and stream both
in one stream. theora_encoder_example wants a separate file for audio
and video, that is why i tried it with two pipes. i didn't find a
solution yet. my first tries have been with ffmpeg2theora instead of
theora_encoder_example, but i couldn't find a way to put audio and video
into one stream with mencoder, so that ffmpeg2theora is able to read it.
an example would still be nice. mencoder/mplayer can output so many
formats and ffmpeg otoh can read so many formats, so i think it is just
a question of finding the suitable one. an example commandline for
mencoder passing data to ffmpeg would be very helpfull, if someone has
