The extradata is generated by encoding a dummy frame, then reset

format other than AV_PIX_FMT_MEDIACODEC, since I'm not sure how
to create a dummy frame safely with AV_PIX_FMT_MEDIACODEC.

The function is called only internally in DSP, so we do not

avcodec/aacdec: Use same AACDecContext for fixed and float
...
Up until now, there was one AACDecContext for the fixed
and one for the floating point decoder. These differed
mostly in certain arrays which were int for the fixed-point
and float for the floating point decoder; there were also
differences in corresponding function pointers.
Yet in order to deduplicate the enormous amount of currently
duplicated code between the float and the fixed-point decoder,
one needs common contexts. Given that int and float have the
same size on all common systems, this commit replaces these
arrays by unions of int arrays and of float arrays. The names
of these arrays have been chosen to be compatible with
AAC_RENAME().
