In avfilter_config_links(), if the current channel layout is not
specified, set the same value of the previous link in the filterchain.

Consistent with the logic used to set the other link parameters.

It was natively integrated into libavfilter.

With this change avconv compiled against libav and linked to ffmpegs libs
will run through the whole fate testsuite without any crashes.
857 tests pass, the remaining tests fail one way or another, which is
to be expected as avconv is not a drop in replacement for ffmpeg
The testsuite used was the ffmpeg fate testsuite, not libavs.

This allows dynamic reconfiguration of the filter.
The callback uses some code that was in the init function. Hence this code
has been moved in its own function.

This filter is based on the MPlayer decimate filter by Rich Felker.

Set x offset values in the range 0-7, rather than in the range 8-1.

The y loop is changed accordingly, to avoid confusion.

This also fixes output difference with the new pending native decimate
filter.

It was natively integrated into libavfilter.

Memory obtained from av_realloc is not aligned enough for AVX.
The other similar allocations are changed too because they use
the same macro. The buffers were cleared afterwards anyway.

Not simd; a compiler should have generated this, but gcc didn't.

Show more information, and only the information stored in the values

Double does not have enough precision to represent all int64 numbers

Fix a memleak that the recent change of architecture made

They were only roughly adapted when error return was
added to the push functions.

Return AVERROR_EOF if all outputs are closed.

It will help forward errors and maintain consistency.

An equivalent framestep filter has been natively integrated.

This filter is inspired upon libmpcodecs/vf_framestep.c, by Daniele
Forghieri.

Only-keyframe output is not supported, since that feature can be achieved
through the more versatile select filter.

This allows the iteration callbacks to discover the internal class and
options, and show them when required.

This is required for iterating through the filter class (without
incurring into a loop).

This is due to the design of components iteration through AVClass
child_class_next() callback, which requires that two components cannot
share the same class.

Require AV_PERM_PRESERVE and leave harmless permissions
alone for the next filter.
