Sorry, I just noticed my idiocy: this should probably be
avctx->sample_rate / 2
But it does not work... :(
(I mean, "-ab" does not have any effect on the final bitrate)
Reducing the faac_cfg->bandWidth value a lot (something like
avctx->sample_rate / 8) does work...
Any suggestion about a proper value for "bandWidth"?
Thanks again,
Luca
