1) DirectShowSource does not need "fps = 15, convertfps = True"
2) ffmpeg "-async 15", " -flags +aic+loop+mv4+naq" and "-mpv_flags +cbp_rd" do not apply
3) why reencode the audio? mux the original audio, something like this:

Code:

## Slide7.avs
ImageSource("slide7.jpg").Lanczos4Resize(800,450).Loop(-1).AssumeFPS(15)

Code:

ffmpeg -i "Slide7.avs" -i "Slide7.mp3" -vcodec flv -b:v 512k -acodec copy -shortest "Slide7.flv"

There is actually no need for AviSynth here, since ffmpeg does slide shows natively... I just don't know how to do it off the top of my head.
