Can't copy external mp3 audio into flv container,
tried both vbr and cbr mp3
two failing command lines follow
ffmpeg -loop_input -i video.png -r 1 -i audio.mp3 -acodec copy -vcodec flv
-qscale 2 -g 5 -cmp 3 -subcmp 3 -mbd 2 -flags trell final.flv -shortest

These methods work:
encoding to avi container then remuxing to flv:
ffmpeg -loop_input -i video.png -r 1 -i audio.mp3 -acodec copy -vcodec flv
-qscale 2 -g 5 -cmp 3 -subcmp 3 -mbd 2 -flags trell final.avi -shortest
ffmpeg -i final.avi -vcodec copy -acodec copy final2.flv
and with mencoder:
mencoder mf://video.png -mf fps=1/45:type=png -audiofile audio.mp3 -ovc lavc
-oac copy -vf harddup -lavcopts vcodec=flv:vqscale=2:keyint=5 -ofps 1 -of lavf
-o Fin.flv
