libavcodec/libgsm.c:148: warning: passing argument 2 of ‘gsm_decode’ discards qualifiers from pointer target type
/usr/include/gsm/gsm.h:68: note: expected ‘gsm_byte *’ but argument is of type ‘const uint8_t *’

libavcodec/libvo-amrwbenc.c:37:5: warning: missing braces around initializer

This is needed because not all players (e.g. MPlayer) are able to distinguish
two different Bink audio decoders when codec_tag is set.

As a positive side-effect, this gets rid of the following warning:
libavcodec/flashsv.c:190:38: warning: assignment discards ‘const’ qualifier from pointer target type

An official specification now exists and it is both more detailed and easier to
understand than the incomplete notes available here.  Also remove ideas on how
to implement an encoder; these notes are already present in the encoder.

This fixes the warning:
libavcodec/libopencore-amr.c:91: warning: missing braces around initializer

Some versions of the GNU assembler do not handle 64-bit
immediate operands containing arithmetic.  Writing the
value out in full works correctly.

This naming scheme is used elsewhere, so it's sensible to be consistent.

This function is called with only 8-byte alignment from
imdct for size 16.  The fft4 function is not called for
the larger FFT or MDCT sizes, so this has no impact on
typical uses.

Set the frame size when decoding DTS audio.

This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields.  Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate.  But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.

Change the test program to output text instead of binary files so
it can be compared easily in FATE.

filter_mb_fast assumed that qscale_table was padded like many of the other tables.

The reference function can be inferred from the direction of the
transform, no need for storing it with each entry.

IDCTs are partially evaluated according to IEEE 1180-1990 (more or
less).  An override is added to the table for implementations known
to not meet the spec requirements.  These variants are run but not
checked for accuracy.

Faster H.264 decoding with ALLOW_INTERLACE off.

Aliasing avoidance and general cleanup.

Avoid aliasing, unroll loops, and inline more functions.

Reduce aliasing problems and unroll mv/ref loop.

Significantly faster deblocking in streams with lots of slices.
