Also drop pointless example.

In particular, avoid out-of-buffer access and crashes with too big
values, and rework documentation accordingly.

This tries to compensate for the errors introduced by
the rounding of pmulhw

Correct the advancement of a pointer to skip over LFE samples as
intended in the loudness computation.

This suggested patch is 3 of 3 for Ticket #2144 "libavfilter ebur128
loudness inaccuracy, irregular time interval, LFE interference".
This suggested patch supersedes the contribution of January 15, 2013
in the thread “[PATCH] lavfi: EBU R.128 irreg time, ch weights, skip
LFE” which combined multiple fixes in one batch.

Correct the recognition of channel layouts for good channel weight
in the loudness computation.
This suggested patch is 2 of 3 for Ticket #2144 "libavfilter ebur128
loudness inaccuracy, irregular time interval, LFE interference".

It is currently possible that such changes leak through from the decoder as
well as a filter could generate such changes itself.
This commit blocks such changed packets unless the encoder declares support.

A broken packet with invalid data in the middle of the stream
should not prevent from decoding the rest of the file.

Work around trac ticket #2264.

The QuickTime specification does not contain any hint that the atom
must not be written in some cases and both the QuickTime and the
AVID decoders do not fail if the atom is present.

This change allows to signal (visually) interlaced streams with
a codec different from uncompressed video.

As a side-effect, this fixes ticket #2202
