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

Return AVERROR_EOF if all outputs are closed.

It will avoid a forward declaration.

It will help forward errors and maintain consistency.

It reduces the lifespan of buffers in filter graphs,
and therefore the memory consumption.

Put the relevant code in one chunk, also check for frame allocation
failures.

Also provide a link to the github FFmpeg page containing the examples.

Fix warnings:
muxing.c: In function ‘write_video_frame’:
muxing.c:326:23: warning: passing argument 2 of ‘sws_scale’ from incompatible pointer type [enabled by default]

There is no point in having the user disable any fastdiv macros.
Besides the condition implementation was broken and only disabled
the C implementation, but no platform specific assembly versions.

The E-AC-3 encoder depends on almost all of the code of the AC-3
encoder, so it makes no sense to enable one without the other.

Fix "assignment discards ‘const’ qualifier from pointer target type" warnings.

Pass pointer to sample buffer instead of channel number to various
functions called from decode_subframe().  Also simplify a few
expressions within this function.

The failures on various architectures and compilers on the RGB(A)
tests seem to have been because of one-off YCbCr->RGB conversion
results. This should make the conversion results match on most if
not all code paths.
