No need to recompute it for each new frame.

This improves the performances just enough to match mp=kerndeint.

Also update the documentation accordingly, and suggest a meaningful range.

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".

Some changes in the border pixels, visually indistinguishable.

Do it all in config_props().

Otherwise events could just pile up if displaying a frame takes more time than
the duration of the frame.

Remove possibly pointless inconsistency with the ported code.

Also specify parameter value ranges consistent with those of the ported
filter.

We are now using a pts based approach, libavutil/libavcodec should provide the
correct pts-es anyway. This also fixes an issue when seeking to a frame with a
pts set to zero.

We use a refresh loop which displays the frames and also does the polling for
pending events in a non-blocking way. If we know the required delay until the
next frame, then exactly that amount of sleeping will be done. After each
handled event we check if we have to display a frame which kind of makes
displaying the frame a high priority event.

This improves greatly the smoothness of the video output especially with 50fps
content.

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.
