I have a new patch. It works. See below.

Had problem with decoding:

$ work.rainier/theora/examples/player_example < /usr/pkg/tmp/theora/testlong.ogg
Error parsing Theora stream headers; corrupt stream?

The encoding seemed to work:

$ work.rainier/theora/examples/encoder_example /usr/pkg/tmp/theora/tkal_aud_short.wav /usr/pkg/tmp/theora/tkal_vid_short.yuv > J.ogg
File /usr/pkg/tmp/theora/tkal_aud_short.wav is 16 bit 2 channel 44100 Hz
RIFF WAV audio.
File /usr/pkg/tmp/theora/tkal_vid_short.yuv is 352x208 24.00 fps YUV12
video.
Compressing....
      0:00:05.07 audio: 73kbps video: 173kbps
done.

The encoded version was a different size than provided with the test.zip:

$ ls -l J.ogg /usr/pkg/tmp/theora/test*ogg
-rw-r--r--  1 reed  wheel   136826 Sep 30  2002 /usr/pkg/tmp/theora/test.ogg
-rw-r--r--  1 reed  wheel   707280 Sep 30  2002 /usr/pkg/tmp/theora/testlong.ogg
-rw-r--r--  1 reed  pkgsrc  163825 May 21 08:58 J.ogg

I assume the old format has changed in the new CVS (which is fine because
I understand that format is changing):

$ work.rainier/theora/examples/player_example < J.ogg

Ogg logical stream 46634f9f is Theora 352x208 24.00 fps video.
Ogg logical stream 47a4053e is Vorbis 2 channel 44100 Hz audio.
Could not open audio device /dev/dsp.

So I patched player_example again. (Thanks for updating CVS so quick!)

<p>Then I could play the video (under NetBSD/i386 1.6; later I'll test
under FreeBSD and OpenBSD):

Done.
