checking for libavcodec.a in /Install/Vlc/ffmpeg... /Install/Vlc/ffmpeg/libavcodec/libavcodec.a
checking for FFMPEG... configure: error: Package requirements (libavcodec libavformat libpostproc) were not met:

Package libraw1394 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libraw1394.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libraw1394', required by 'libavcodec', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables FFMPEG_CFLAGS
and FFMPEG_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

surely ffmpeg was compiled wiht --enable-libdc1394 and de/muxers
it's feisty ubuntu and libraw1394-dev is installed
anyone has any solution for this problem

cheers to our developers and all others

alright...
seems like configure script is broken, this doesn't work:
--with-ffmpeg-tree=PATH
take above off and use flags to linker:
LDFLAGS="-L/opt/lib -L/Install/Vlc/ffmpeg/libavcodec -L/Install/Vlc/ffmpeg/libavformat -L/Install/Vlc/ffmpeg/libpostproc,-I/opt/include"

notice that $=/Install/Vlc/ffmpeg, so alter it, same with $/opt
am I right?
cheers

I'm experiencing the same problem on Debian Etch with an up-to-date FFMPEG build. Here are ffmpeg build options I used:
--enable-static --disable-shared --enable-gpl --enable-pp --enable-pthreads --enable-liba52 --enable-liba52bin --enable-libamr-nb --enable-libamr-wb --enable-libdc1394 --enable-libfaac --enable-libfaad --enable-libfaadbin --enable-libgsm --enable-libmp3lame --enable-libogg --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --disable-swscaler

I think lejeczek was talking about the configure command arguments as can be found in the file .cmd generated by build-vlc.

Still I don't understand what his solution was or could not get it to work.
lejzczek, how did you build VLC ? I need an up-to-date SVN build of VLC to transcode a live into 3GP and serve it over RTSP.
