Justin Ruggles 6271794041 aacdec: use a scale of 2 in the LTP MDCT rather than doubling the coefficient
table values from the spec.

Alex Converse e4744b59aa Large intensity stereo and PNS indices are legal. Clip them instead of
erroring out. A magnitude of 100 corresponds to 2^25 so the will most
likely result in clipped output anyway.

None of the conformance streams fall in the range that need to be clipped.

Alex Converse 187a537904 Convert some undefined 1<<31 shifts into 1U<<31.
According to ISO 9899:1999 S 6.5.7/4:

The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits
are filled with zeros. If E1 has an unsigned type, the value of the
result is E1× 2^E2, reduced modulo one more than the maximum value
representable in the result type. If E1 has a signed type and
nonnegative value, and E1× 2^E2 is representable in the result type, then
that is the resulting value; otherwise, the behavior is undefined.

Thadeu Lima de Souza Cascardo 08d804ab6a aac_latm_dec: use aac context and aac m4ac
When decoding latm config, use the corresponding aac context and its
m4ac instead of using NULL and a local variable. This fixes decoding of
audio in MPEG TS from SBTVD (the Brazillian Digital TV Sytem), when
there is no extradata. This is the case when using the decoder with
gst-ffmpeg and a GStreamer mpegts demuxer.
