Same here. Strangely, however:
$ strings /usr/lib/gstreamer-0.10/libgstffmpeg.so | grep flv
flvdec_init
flv_iformat
flv_decoder
flv_h263_decode_picture_header
video/x-flv
flvversion
flv format
skipping flv packet: type %d, size %d, flags %d
$ gst-inspect ffmpeg | grep flvffmpeg type: flv
ffdemux_flv: FFMPEG flv format demuxer
ffdec_flv: FFMPEG FLV video decoder-- Sam Morris http://robots.org.uk/ PGP key id 1024D/5EA01078 3412 EA18 1277 354B 991B C869 B219 7FDB 5EA0 1078
