Hi all,

I posted a similar problem a while ago, but unfortunately did not get
any comments/replies. I am still having the same problem, and any
suggestions/help would be appreciated.

I am running VLC 0.8.6a on a custom Linux build w/ x264 (version
svn-634), faad2 and faac (versions 2.5 and 1.24, respectively), and
ffmpeg (version svn-8387) libraries installed.

Here is the ./configure options (a lot of the options are disabled):

./configure --host=$CROSSTOOL_TARGET --build=$CONFIG_BUILD --prefix=/usr
- --enable-v4l --enable-faad --disable-libcdio --disable-libcddb
- --disable-cdda --enable-httpd --disable-vlm --disable-dvdnav
- --disable-dts --disable-vcd --disable-libmpeg2 --disable-vorbis
- --disable-cmml --disable-x11 --disable-xvideo --disable-glx
- --disable-xinerama --disable-opengl --disable-sdl --disable-freetype
- --disable-fribidi --disable-libxml2 -disable-a52 --disable-mad
- --disable-mpc --disable-mod --disable-mkv --disable-skins2
- --disable-wxwidgets --disable-visual --disable-daap --disable-bonjour
- --disable-growl --disable-notify --disable-smb --disable-gnomevfs
- --disable-ogg --with-ffmpeg-faac

This box (A) captures video from a camera, encodes w/ x264 and streams
it on  to the network. A vlc (C) client running on a Kubuntu box (Debian
package 0.8.4-svn20040920, can get this stream via UDP and display it.
It can also published it via mmsh. Other VLC clients can open this mmsh
stream.

A  ---------> C (works)

Now, if I add a third box (B), which is identical to (A) is but in
between A and C, such that the sole purpose of (B) is to get the stream
and forward to UDP to (C), the VLC instance running in box (C) can no
longer display it

A  ----------> B ----------> C (does not work)

Now, there is network connectivity, and the vlc client (C) receives the
packets. If I run vlc debug on the box (C), I see that the packets are
received, but VLC is unable to start decoding:

Since the first case works, but not the second, I am guessing that some
configuration is going wrong in my custom builds. Or there is a mismatch
in versions/expectations of the decoders.

Could anybody suggest a solution?

Thanks in advance,
GA
