[FFmpeg-user] HLS-webm and unicast

As one would see I am new to this list and to ffmpeg and to ffserver

This is what I would like to do:
Receive a rtp stream from a broadcast encoder that encodes a HD 1080i source and outputs a MPEG 4 stream as a multicast.  I have everything setup where ffmpeg can see the multicast stream.

I have two versions of ffmpeg and ffserver running on Ubuntu 14.04.03.

One is  a yum installed from a repository:
ffmpeg version 2.4.3-1ubuntu1~trusty6 Copyright (c) 2000-2014 the FFmpeg developers

And the other is a compiled version I got from the following site:  https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

I tried to get the webm stream working but I'm running into issues where ffserver would sometimes crash or when trying to view the stream in Chrome it would say the stream is corrupt.
The following is the ffserver.conf file I'm using:

HTTPPort 8090
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 100000
CustomLog /home/eng/ffmpeg_sources/ffmpeg/log/ffserver.log

FileMaxSize 1G
Launch ffmpeg

<Stream test.webm>
Feed feed1.ffm
Format webm
AudioCodec vorbis

VideoCodec libvpx

VideoFrameRate 25
AVOptionVideo flags +global_header
AVOptionVideo cpu-used 0

AVOptionVideo quality good
PreRoll 10
VideoBitRate 400

# Only allow local people to get the status
<Stream stat.html>
Format status
ACL allow localhost
ACL allow

This is what I'm entering in the command line:

                ./ffserver -f /etc/ffserver.conf & ffmpeg -I rtp:// http://localhost:8090/feed1.ffm

As I mentioned I would like to basically have the rtp stream into Ubuntu and have ffserver stream a HLS and a webm and send the exact same input, without touching the stream, as a unicast to a particular decoder.  Is this possible?

BTW how does one search the list archive?

Any help would be greatly appreciated.
