[FFmpeg-user] no encoding of VP6 flv files

I use ffmpeg for merging a video track (flv) and a audio track (mp3) 
together without new encoding. It runs on a debian linux server. For 
building a new header I use flvtool2. That works perfect with a flv file 
encoded with h.264 as video input but does not work with flv files 
encoded with VP6. I need this to use alpha channel. Is this a bug or is 
VP6 not provided by ffmpeg? Here is the command line: ffmpeg -i 
"video.flv" -i "audio.mp3" -vcodec copy -acodec copy "video_and_audio.flv"

Best regards
