nstreams is assumed to be 1 at that point, so the loop is pointless.

"str" is misleading here (it's often used for string). "sid" makes more
sense to identify a stream id.

There is no point in a distant definition of a small function like this
used only once.

Additional spacing to distinguish better the block.

Fixes compilation with XCode 3.2.6.
Fixes ticket #1736.

These functions do not benefit from being inlined.  They are large,
and there are no opportunities for constant propagation.

It internally decodes as float and then converts to s16 by a call to
float_to_int16(). The caller can do this just as well by using lavr.

Gray8 is not considered to be paletted, so this would cause an invalid
write.

Fixes bug 367.

Some implementations of sscanf do not handle a space before a trailing %n
properly.

As an example, MSVC's does this for the second insatnce in this patch, for
an input of "0x3:c0=c1:c1=c0":
    1) Match the final "c0" or "c1".
    2) Realize it's at the end of the string.
    3) Check for %n.
    4) There is no %n, but a space instead.
    5) Leave 'len' unitilialized.

So, move it out of the sscanf format strings, and call skip_spaces instead.

This bug does not affect skip_spaces since %n is the first and only formatting
string.

Should also be faster (though I doubt that hardly ever matters
for the usage here).

Also remove the pointer copy. Since we do not need to reset the
pointer to the start of the string, it is not needed anymore.

This updated version does not deviate from previous behavior on default value of 'buffer_size'

I skipped porting 'sources', 'block' options for now as they're parsed seriously. So i added TODO remarks.

The YUV channels of VP6 are encoded in a highly linear fashion which does
not have any slice-like concept to thread.  The alpha channel of VP6A is
fairly independent of the YUV and comprises 40% of the work.  This patch
uses the THREAD_SLICE capability to split the YUV and A decodes into
separate threads.

Two bugs are fixed by splitting YUV and alpha state:
- qscale_table from VP6A decode was for alpha channel instead of YUV
- alpha channel filtering settings were overwritten by YUV header parse

Rather than cleverly managing frame pointers with swaps to avoid
