9d3050d3e9 wma: don't return 0 on invalid packets. 
Return 0 means "please return the same data again", i.e. it causes an
infinite loop. Instead, return an error.

26f548bb59 fft: remove inline wrappers for function pointers 
This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

This will be beneficial for use with the audio conversion API without

ff00b94e9d WMA: use type punning and unroll loops in decode_exp_vlc() 
GCC does stupid things if these assignments are done using floats
directly, so fill the runs using integer operations instead.  Also
unroll the loops since the length is always a multiple of 4.

952e872198 Drop unused args from vector_fmul_add_add, simpify code, and rename 
The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively.  This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better
match the new operation.

7d485f165f Support for getting (i)MDCT output multiplied by a constant scaling factor. 
Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in
'ff_mdct_init' function and slow down initialization a bit.

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.
