681c180dc4 Make avcodec_open set codec_id and codec_type if they haven't been set. 
This fixes the API breakage introduced by the check that avctx codec id and type
match the opened codec and should make (almost?) all applications work again.

43d7c6118d put_bits can only reliably write up to 31 bit bits, above it relies on 
undefined shift behaviour.
Document this, fix the assert and add a put_bits32 to handle writing 32
bits and use that where necessary.

ff00b94e9d WMA: use type punning and unroll loops in decode_exp_vlc()

directly, so fill the runs using integer operations instead.  Also

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

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).

1.3x and 3% on G4.
Though I think only part of this speedup is due to my optimizations per se;
some of it is that I got a better roll on the GCC random code generator.
Trivial reorderings of this function have a disproportionate effect on speed.

21c6a0258c Remove useless alignment from MpegEncContext.intra_scantable 
The first member of struct ScanTable is a simple pointer, extra alignment
of which serves no purpose.  The alignment specifier was added along with
some Altivec optimisations also adding a 16-byte-aligned array at the end
of struct ScanTable.  Presumably the redundant, outer alignment was added
by mistake.  The inner one is clearly sufficient.

afe08a728a PPC: remove unnecessary alignment on local variables 
Storing a single element from a vector where all elements have the same
value does not require an aligned destination.  Which element is stored
depends on the alignment of the destination address, but since they all
have the same value, the result is the same regardless of the alignment.

0314dead4e eval: replace variable-length array with av_malloc/free 
There is a theoretical possibility to pass a very long string to ff_parse,
which could crash if allocated from the stack.  This allows the allocation

d15f2e00c5 Fix bug caused by difference in stride and picture width. 
When a frame is allocated using libschroedinger routines, the frame data size
does not match the actual frame size if the width is not a multiple of 16. So
we cannot do a straightforward memcpy of the frame returned by libschroedinger
into the FFmpeg picture as the stride differs from the width.

Fix this bug by allocating for the libschroedinger frame with the dimensions
in AVCodecContext within libavcodec and passing the frame to libschroedinger.
