[Icecast] theora streaming problem...

Mon Feb 21 22:04:34 UTC 2005

hi everyone!

i'm playing around with theora streaming for the linux audio conference 
2005 (http://lac.zkm.de).

i checked out svn.xiph.org/trunk, built all ogg, vorbis, speex and 
theora related libs from scratch, then pulled icecast-2.2.0.

three issues:

[1]

icecast runs fine as always, but when i do
cat myvideo.ogg | oggfwd myhost 8000 mypasswd /test.ogg, the stream dies 
after a few seconds. (the icecast log is appended below.)

the same command sequence with an ogg vorbis audio file instead of the 
theora video works without problems.

[2]

i tried to follow oddsock's howto at 
http://www.oddsock.org/guides/video.php, but ezstream does not compile 
for me. it bails out with

gcc -DHAVE_CONFIG_H -I. -I. -I..  -Wall -ffast-math -fsigned-char 
-I/usr/local/include  -I/usr/include/libxml2-pthread -g -O2 -c `test -f 
'ezstream.c' || echo './'`ezstream.c
ezstream.c: In function `streamFile':
ezstream.c:385: warning: implicit declaration of function `sleep'
ezstream.c: In function `streamPlaylist':
ezstream.c:406: warning: unused variable `ret'
ezstream.c: In function `main':
ezstream.c:576: error: `SHOUT_FORMAT_OGG' undeclared (first use in this 
function)
ezstream.c:576: error: (Each undeclared identifier is reported only once
ezstream.c:576: error: for each function it appears in.)
make[2]: *** [ezstream.o] Error 1

probably something obvious, but i could not find where SHOUT_FORMAT_OGG 
is defined... libshout is installed, and it's not in there.

[3]

when i transcode an mpeg2 file to theora, it's barely faster than 
realtime on an athlon64 4000+. is this to be expected, or did i forget 
some optimizations? here's the ffmpeg output, so that you can see the 
stream properties.
