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.

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).

currently a overflow there should be impossible but future changes to the code could easily introduce a bug that no longer limits the 2 values sufficiently so better protect it via av_assert. Signed-off-by: NMichael Niedermayer <michaelni@gmx.at>
