VLC doesn't have any native support for flv AFAIK. We have a ffmpeg
demuxer that could take care of it, but we certainly wouldn't be able
to decode the video data inside anyway (unless it uses the old vp3 or
any other open codec. Can you check if vlc -l outputs a line looking like

ffmpeg                ffmpeg demuxer

About your h264 on amd64 issue, it is probable debian and the nightlies
are compiled against a version of ffmpeg that has issues with playback
of h264 on amd64. Without any debug message, I cannot tell more (and I
don't think any of the developpers has the hardware to test it).

Could you send some more debug info ? The best would be to test with a
self compiled version of VLC and different versions of ffmpeg.
Compiling VLC on debian is pretty easy, but still requires to install
lots of dependancies.
