[FFmpeg-user] HLS-webm and unicast

[Reaz Baksh]

Hello
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
HTTPBindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 100000

# Only allow local people to get the status
<Stream stat.html>
Format status
ACL allow localhost
ACL allow 192.168.0.0 192.168.255.255
</Stream>

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

                ./ffserver -f /etc/ffserver.conf & ffmpeg -I rtp://192.168.1.101@239.5.1.1:1234 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.

Thanks
