Using an unsigned variable avoids problems with overflows.
There is further no need for a 64-bit intermediate here.

Interlaced videos can contain progressive frames too and now wrong scantable
is selected for them.

This fixes a compile error on mingw32 when using p->thread
directly (as if it were a pointer) to track thread existence,
because the type is opaque and may be a non-pointer.

As old bits are shifted out of the accumulator, they cause signed
overflows when they reach the end. Making the variable unsigned fixes
this.
Signed-off-by: Mans Rullgard <mans@mansr.com>
The way these values are used, they should have an unsigned type.
A similar change was made for mpegvideo in cb66847.
Signed-off-by: Mans Rullgard <mans@mansr.com>
This simplifies the decoder so it doesn't have to process an in-packet header
or handle arbitrary-sized packets. It also fixes decoding of files with large
headers.
Instead of using fixed coefficients, the correct way is to calculate the
coefficients using the highpass cutoff frequency from the ADX stream header
and the sample rate.
