This fixes clipping if the encoder input used the full 16 bit
input range (samples with a magnitude below 16383 worked fine).
The filtered subband samples should be 15 bit maximum, while
the code earlier produced them scaled to 16 bit.
This makes the decoder output have double the magnitude
compared to before.
The spec reference samples doesn't test the QMF at all, which
was why this part slipped past initially.

The container has no timestamps and the framerate isn't stored in the
data either.
The decoder sets codec timebase to experimentally found value 1/15. Do
the same for the demuxer too, it should at least be better than the
default 1/90000.
This fixes duplicate timestamps on mp2 in ts with non seekable input.
It also fixed the fate pva demux timestamps.

come first, "Frames" behind.

Fixes invalid reads while initializing the dequant tables, which uses
the bit depth to determine the QP table size.

This makes the packetization spec compliant for cases where one single
GOB doesn't fit into an RTP packet.

It appears there are corner cases with damaged input that can lead
to small overreads.
