AAC transcode problem

There is a problem with transcoding from an aac stream. The output is at half speed, this because the sample frequency and number of channels are reported wrong. For example when you transcode an 44.1Khz stereo AAC stream to MP3 (it doesn't work with any encoder) it will be outputted as 22Khz mono.

I think this is caused by the fact that the sample frequency and number of channels changes after aprox. a second when the aac stream starts. This happens also in winamp (haven't tried something else, but winamp doesn't use faad).

So maybe the transcoder should be init after the aac stream change (maybe an extra option to delay the transcode init for a second or 2)
