[FFmpeg-user] Streaming Webm from ffserver

[Arunava]

Hello,

I am trying to stream webm from ffserver. I am able to stream using rtsp 
from ffserver.
But am stuck trying to stream in webm format.
The feed to the server is from an android device using the javacv libraries.

I have compiled ffmpeg with ogg and vorbis libraries.

I get the following error when i hit the webm url:

Here are the build details:

The ffserver.conf stream section
<Stream test.webm>
Format webm
Feed feed1.ffm

Is it something that could be wrong on the client that feeds the ffserver.
I am setting the framesize as 176x144, the framerate as 30 and the 
avcodec as H264.

Thanks,
