theora - Nov 2009 - ffmpeg2theora 0.25 : This doesn't look like a Speex file

why is this happening?

$ ffmpeg2theora /dev/video0 -f video4linux2 --inputfps 15   -o - |
oggfwd  myhost 8000 mypass  /test.ogv
[video4linux2 @ 0x196b8c0][3]Capabilities: 4000001
[video4linux2 @ 0x196b8c0]The V4L2 driver changed the video from

        notification: This doesn't look like a Speex file
  0:00:00.93 audio: 0kbps video: 73kbps, time elapsed: 00:00:03

and it dies thereafter.

i work around this using ffmpeg:

ffmpeg -f video4linux2 -t 60 -s 640x480 -r 15 -i /dev/video0 /tmp/blah.ogg
and
cat blah.ogg | oggfwd  myhost 8000 mypass  /test.ogv

Let me know in case we need more info on this. thx in advance.!

libspeex writes "This doesn't look like a Speex file" when passed
a
header packet which isn't actually one (eg, when one tries to probe
for Speexiness).
It doesn't in itself mean that something is wrong, just that the data
probed isn't Speex.
