ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

72415b2adb Define AVMediaType enum, and use it instead of enum CodecType, which
is deprecated and will be dropped at the next major bump.

d2df291f73 ff_msmpeg4_decode_init() calls ff_h263_decode_init() which calls
MPV_common_init(), so calling both is redundant and leads to memory
leaks in WMV3/VC-1 decoder. Thus use only the first function in
WMV3/VC-1 decoder initialization.

95ce961d88 Since some junk may be or may be not present before actual VC-1 extradata,
search for real extradata start instead of always skipping one byte.

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.

2ba8301769 Mark all pix_fmts and supported_framerates compound literals as const.
Makes no difference for gcc but at least icc can put them in .rodata then.

e0f58e39c4 Do not check for both CONFIG_VC1_VDPAU_DECODER and CONFIG_WMV3_VDPAU_DECODER,
the former depends upon the latter.

351653a51e VC-1/WMV: Remove redundant ff_init_block_index() calls.
These are only supposed to be called once per row, not once per macroblock.
~1.5% faster according to oprofile.

010f98f96a VC-1/WMV3 decoding: don't clear blocks unless they're actually used.
~8% faster VC-1 decoding.
Possible future optimization: clear blocks after use instead of before, and for
DC-only blocks, only clear the DC coefficient.

4f717c69ed idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.
Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).

shared between decoder and parser in vc1.c.
