Removing instead of updating as previously pointed-to page
(now http://dvd.sourceforge.net/dvdinfo/) is already linked
from dvd.sourceforge.net's homepage as: "Collection of
information on file formats/data structures relating to DVD
navigation/SPUs."
This method replace the manual adjustment of PTS and DTS to avoid
negative DTS issues. Using this method will also update the segment so
we don't loos sync.

Provide new frame-packing property to directly set
x264enc frame packing, or pass through upstream settings
The explicit layout from the frame-packing property is
preferred over any info from the caps.
a52_init initializes the IMDCT global state as well as creating
a new state. When two A52 decoders are created (eg, when two AC3
tracks are contained in a video), calls to a52_init may happen
at the same time, and the IMDCT initialization is not reentrant.

This allow using external pools that have different strides from the
default. These strides need to respect certain rules, which we check
and if these are not met, we fallback to generic pool.
https://bugzilla.gnome.org/show_bug.cgi?id=735379
This is a rewrite of the pool negotiation and configuration. Direct
to output decoding is now achieved by configuring the pool using
video-alignment. This removes copies when dealing with any elements that
supports VideoAlignment, and enable usage of generic video buffer pool,
XVImagePool and GLPool. It drops the crop meta implementation for now.

A pipeline like:
gst-launch-1.0 filesrc location=file.ts ! tsdemux ! mpegvideoparse ! mpeg2dec ! vaapisink
would look bad when file.ts contains 704x576 video, because vaapisink would
give you buffers of stride 768, but libmpeg2 was not told about this and
used a stride of 704.
Tell libmpeg2 about the stride from downstream; in the process, teach it to
reject buffer pools that don't meet libmpeg2's chroma stride requirements

The meaning of the max latency is *not* the maximum latency this element will
introduce. It is the maximum latency this element can endure without
overflowing any buffers, which is infinite for x264enc.
Fixes latency configuration in zero latency mode, where max latency was
becoming 0... which usually won't work well if something else introduces
latency as then max < min in the end, and latency configuration just fails.
There is no reason x264enc should enforce a maximum allocation size.
The maximum is normally set by buffer pool which cannot grow, but we
don't offer a buffer pool. This would lead to stall when used with
element that don't implement allocation query.

Currently we only shift DTS to compensate that we don't support negative
timestamp. This cause a problem that PTS is no longer >= DTS and may
make muxers live much harder. Instead, shift both PTS/DTS forward. Also
remove all the hack to handle this which seems the result of thinking libx264
is bugged.

They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.
New changes to gstvideo will reset all the video info state
when calling _set_format, overwriting what was previously set
in the preceding code.
The comment says the following code is meant to preserve the
pre-crop size, so let's just keep the size and related data
as this does not seem to break anything else (this is what
the _set_format call would have set before the change that
reset all data, except the colorimetry).
