Some changes in the border pixels, visually indistinguishable.

This reverts parts of d6d5ef5534d582, that didn't work right. (The
tests that were added failed on big endian, and the output looked
garbled on little endian as well.)
This is due to the fact that the intermediate scaling values (from
e.g. hScale8To19_c or hScale16To19_c) are stored as int32_t and
thus requires a separate output function, while yuv2gbrp_full_X_c
only interprets it as int16_t.

Do not rely on get_buffer initializing them.
Changes yadif tests (off by one in one border pixel), because yadif
reads from those uninitialized lines.

The FATE sample contains some pixels with value 0, but the palette
stored in the file contains only values from 16 up. Because the default
and cmdutils get_buffer() initialize the data to 0x80, they appear as
gray dots.
After this commit they change to black dots, which is probably still
incorrect but less visible and doesn't rely on get_buffer() initializing
the data.

The bottom line was invalid before.

Setting it to zero (instead of 128, as the default get_buffer() does)
also produces more correctly-looking output.

Do not assume that frame dimensions are mod16 (or that height is mod32
for interlaced).

This allows us to remove FF_IDCT_WMV2, which serves no practical purpose
other than to be able to select the WMV2 IDCT for MPEG (or vice versa)
and get corrupt output.
Fate tests for all wmv2-related tests change, because (for some obscure
reason) they forced use of the MPEG IDCT. You would get the same changes
previously by not using -idct simple in the fate test (or replacing it
with -idct auto).

Also rename the test to reflect that the video track is Theora, not VP3.

Add some additional checks for EOF and print error messages on an incomplete
header or packet.
FATE reference updated for id-cin-video due to the demuxer no longer
returning a partial video packet at EOF.

Snow is a toy codec with no real-world use and horrible code.
|

|
The background changes from 128 (used by the default/cmdutils
get_buffer()) to 0. This looks more correct.
|
|
Do not overwrite linesize set by get_buffer().
The last frame in the FATE test is not decoded anymore, since the file
is cut and a part of it is missing.

The initial testing of the VFW binary codec was flawed,
likely due to an AviSynth bug.
Re-testing using VirtualDub and various professional editing
applications has revealed it should have been flipped.

Some shells, e.g. minix3, have a broken 'test' builtin which fails
if the first operand of a binary operator looks like a unary operator.
Prefixing the values with 'x' prevents this from happening.

Each fate-seek test depends now only on the corresponding fate-acodec,
fate-vsynth2 or fate-lavf test which creates the file seek-tests
operates on. The tests and references are renamed to match the test they
depend on.

Now that libavutil can be disabled, this should be conditional.
