cannot find encoder - WMV2

Postby yeti » 10 Sep 2007 14:00

Hi all,
my destination is to encode a device at a vista client
and to send it to linux server which will work as a multicasting server .

On vista computer:

sout=#transcode{vcodec=WMV2,vb=1024,scale=1,acodec=mp3,ab=192,channels=2}:duplicate{dst=std{access=http,mux=asf,
dst=:1234}'

this code run at linux server
vlc -vv http://@ipadress:1234 --sout '#transcode{vcodec=wmv2,vb=96,scale=1,acodec=mp3,ab=32,channels=2}:duplicate{dst=std{access=mmsh,mux=asfh,dst=:9999}'

Server: debian etch
vlc 0.9.0-svn
ffmpeg --version
FFmpeg version SVN-r7222, Copyright (c) 2000-2006 Fabrice Bellard, et al.
configuration: --enable-mp3lame --enable-xvid --enable-gpl --enable-pp
libavutil version: 49.1.0
libavcodec version: 51.25.0
libavformat version: 51.6.0
built on Dec 6 2006 01:15:36, gcc: 3.3.5 (Debian 1:3.3.5-13)


Audio is ok. But I don't see video:
Problem is that vlc can't find encoder wmv2

Can you help me.

Thanks.

1. Why are you transcoding the stream on the relay-server side again? It should be sufficient to just remux via mux=asf or mux asfh (asf/asfh depends on vlc version, i think)

2. I am getting the same "cannot create packetizer output (WMV2)" on a 9.8.6a Janus vlc... Can anyone reading this thread give and answer? (is it because I am using the debian version and as with mp3 patents prevent wma from being included?)
