Defining restrict results - for some compilers - in changing other
uses of the restrict keyword also, e.g. __declspec(restrict) gets
changed to __declspec(__restrict) on MSVC. This causes compilation
failures. Therefore, using a private namespace macro instead is
more reliable and robust.

This can easily happen when the caller is using a custom AVIOContext.

Behave as if the filename was an empty string in this case.

Basically to make code clearer and adherent to the
standard. RFC 1321, on page 2 states

Let the symbol "+" denote addition of words (i.e., modulo-2^32
addition). Let X <<< s denote the 32-bit value obtained by circularly
shifting (rotating) X left by s bit positions.

on page 3, section 3.3 states:

A four-word buffer (A,B,C,D) is used to compute the message digest.
Here each of A, B, C, D is a 32-bit register.

so the algorithm needs to work with integers that are exactly 32bits
in length. And indeed in struct AVMD5 the MD buffer is declared as
"uint32_t ABCD[4];", while in the function that performs the block
transformation the state variables were "unsigned int"s. On
architectures where sizeof(unsigned int) != sizeof(uint32_t) this
could be a problem, although I can't name such an architecture from
the top of my head.
On a side note, both the reference implementation in RFC 1321 and the
gnulib implementation (used by md5sum program on GNU systems) use
uint32_t in the transform function.

This filter changes the number of samples on single output operation.

Based on a patch by Andrey Utkin <andrey.krieger.utkin@gmail.com>.

The filter now supports a configurable number of outputs.

Improve overall consistency, allow some factorization.

Frei0r recently changed website host.

Remove duplicated out-of-loop init code, and do color matrix
initialization at the beginning of each y iteration.

Allow factorization and avoid an useless matrix update in the last
iteration.

The previous table appears to be wrong (it was copied from the original
MPlayer super2xsai filter in order to keep binary compatibility).

The new table is consistent with the init code and apparently fixes a
combing artifact on the left edge of the generated image.

Use the same values of the video output link.

Avoid the need to override the default_start_frame() with an ad-hoc
start_frame() callback.

In particular, fix the super2xsai filter which was setting the
input w/h values in the output.

The function will abort through an assert if the source is not defined,
or if the internal state of the source is inconsistent (e.g. type = AUDIO
&& !src->audio).

Help debugging.

Return AVERROR(EINVAL) in case of invalid coded size.
