18b6a69ce9 Revert "VC1: merge idct8x8, coeff adjustments and put_pixels." 
This reverts commit f8bed30d8b. The reason
for this is that the overlap filter, which runs after IDCT, should run
on unclamped values, and thus IDCT and put_pixels() cannot be merged if
we want to attempt to be bitexact.

case the returned frame was not the same one previously returned but a

Justin Ruggles
31d76ec288 In avcodec_open(), set return code to an error value only when an error occurs 
instead of unconditionally at the start of the function.

This fixes a bug where a successful call to ff_thread_init() masks errors that
occur after that point in the function.  It also makes future bugs like this
less likely since the error code is now set near to the point in the code
where the error is found.

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.

This allows the AC-3 decoder to be used directly with RealMedia
decoders that unlike the libavformat one do not byte-swap automatically.
Since the new code is only used in case we would fail directly otherwise
there should be no risk for regressions.

323e6fead0 ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage. 
This increases the accuracy of coefficients, leading to improved quality.
Rescaling of the coefficients to full 25-bit accuracy is done rather than
offsetting the exponent values. This requires coefficient scaling to be done
before determining the rematrixing strategy. Also, the rematrixing strategy
calculation must use 64-bit math to prevent overflow due to the higher
precision coefficients.
