Do not read padding or out-of-buffer values when computing the output
value for a pixel close to the image buffer edge.
This avoids non visible artifacts which affected the output checksum.

Subject: [FFmpeg-devel] [PATCH] lavfi/mp/mcdeint: avoid uninited data read
Date: Thu, 30 May 2013 18:57:14 +0200
Currently the WebVTT demuxer parses the cues but throws away
the cue id (the optional first line of the cue) and cue
settings (the optional rendering instructions that follow
the timestamp).
However, in order to write inband text tracks (to WebM
files), the entire cue payload from the WebVTT source must
be preserved.
This commit makes no change to the data part of the output
buffer packet (where the actual cue text is stored), but
does add the cue id and settings as a side data items, if
they're present in the cue. Existing code that cares only
about the data part of the packet can continue to ignore the
side data.
There are two new packet data type flags,
AV_PKT_DATA_WEBVTT_IDENTIFIER and
AV_PKT_DATA_WEBVTT_SETTINGS.
The padding data is assumed to be 0 in several places, notably in
subtitles. This problem was not detected with fate-sub-srt test because
the first element of the side data (x1) is 0 in the test, so the
trailing side data present in the packet wasn't read by the decoder. The
issue can be observed with a large enough x1.
It is also noted in FF_INPUT_BUFFER_PADDING_SIZE doxy that MPEG
bitstreams require that padding with 0, so it might fix other issues.
SDL surface pitch is 16bit, to avoid possible overflows, we limit the window
width to 16383. Fixes ticket #2428.

Showing A-V diff has no use if there is no audio and video stream, but showing
the audio or video clock difference to the master clock can be useful.

It was raised to 4 because of a theoretical issue, if we ensure that we do not
return from the display function without popping one picture from the queue,
then its OK to use the old size.

Currently, standard tables like AV_CRC_32_IEEE and such are being generated (or
provided in case the user compiles with hardcoded tables) with only 257 elements.
We're missing a considerable boost in performance by not making them with a size
of 1024 elements instead.

Indeo 4 has quantiser range 0-31 instead of 0-23 for Indeo 5, and clipping
quantiser leads to incorrect quantisation and DC prediction on low-quality
videos.
This fixes bug 259.
Since we don't check for seek table integrity in the decoder anymore,
check it in the demuxer instead (Only tta files are guaranteed to have
one, and it should be valid there).
Check also for header integrity, since the check done in the decoder
is ignored because matroska doesn't store the header at all.
