53f9f9c91b When BitsPerSample tag is not present in TIFF, that means file is
monochrome, so initialize picture before decoding.
This fixes decoding monochrome files produced by lavc TIFF encoder.

ebb651d5f2 Make sure that dv encoder initializes all encoded packet data.
The specification does not say which value to use for unused
parts, so fill all unused bytes with 0xff, which is consistent
with what DV usually uses for reserved or unused parts.

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.

a55247e761 Specify maximum sample rate of MLP by defining the factor relative to 48000
instead of directly.
This makes clear that the code assumes the maximum sample rate to be
a multiple of 48000 and also removes the division from the MAX_BLOCKSIZE
macros, which causes an issue with the Solaris assembler where "/" is
a comment marker unless the --divide option is used.

c05df6895f Use ff_msmpeg4_decode_init to initialize ff_msmp4_mb_i_vlc since static
VLC tables should only be initialized from one place.
This initializes/calculates more VLC tables than necessary for VC1 decoding,
but this is only done once and only a small overhead in time and space (maybe
30 kB) it seems not worth adding a separate function.

138fe83215 Perform the DC prediction reversal immediately after decoding all of
the DC coefficients. This has a greater probability of leveraging the
coefficients while they are still cached.

When testing with the Big Buck Bunny 1080p video, I consistently saw
improvements of 500k-600k dezicycles per run (through
reverse_dc_prediction()) thanks to this move.

40e26453c4 Use a custom radix sort implementation instead of qsort in dnxhd encoder.
This is mainly to avoid test failures due to implementation-defined
behaviour of qsort when elements are equal, giving different results
for each of FreeBSD, Linux/glibc and Solaris.
In addition it is about 35 % faster, effect on overall speed is minimal
though (< 2%).
Regression tests are unchanged (i.e. identical to Linux/glibc).
