i think we had a missunderstanding... the problem is the demuxer not codec.

in libavformat/flvdec.c

st->codec->codec_type = CODEC_TYPE_VIDEO;
            switch(flags & 0xF){
            case 2: st->codec->codec_id = CODEC_ID_FLV1; break;
            default:
                    av_log(s, AV_LOG_INFO, "Unsupported video codec (%x)\n", flags & 0xf);
                st->codec->codec_tag= flags & 0xF;
            }
    }

i believe the new codec needs to be defined here. so that mplayer can play
it using the vp6vfw.dll binary codec.

also i'd love to see rtmp:// support in ffmpeg/mplayer, red5 ( osflash.org/red5 
seems to have some start on the rtmp protocol)

rtmp://fcs.fox.speedera.net/vod/fcs.fox/simpsons/sexy_video.flv
for s sample rtmp stream
