62ee0e6a97 Revert "swscale: use 15-bit intermediates for 9/10-bit scaling."
This reverts commit ac0fb59348. It
causes valgrind errors which I'll want to investigate before
resubmitting this.

7d7bacf0f1 swscale: fix overflow in 16-bit vertical scaling.
We operated on 31-bits, but with e.g. lanczos scaling, values can
add up to beyond 0x80000000, thus leading to output of zeroes. Drop
one bit of precision fixes this.

f44d50a94c swscale: fix 16-bit horizontal scaling underflow.
When using e.g. lanczos scaling, values can drop below 0, so they
should never be unsigned.

42d622fab3 swscale: fix 16-bit scaling when output is 8-bits.
We would use the second half of the U plane buffer, rather than the
V plane buffer, to output the V plane pixels.

8a8d0ce208 swscale: for >8bit scaling, read in native bit-depth.
For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

ef1ee362b3 swscale: implement >8bit scaling support.
This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

76f8a96e00 [PATCH] Update pixdesc_be fate refs after adding 9/10bit YUV420P formats.
Also remove code that overwrites the C versions of functions in
sws_init_swScale_altivec(), so that it uses the C functions of files
if no altivec-optimized version exists.

c8f487deae swscale: fix YUV420P 9/10bit support.
Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.

f4b1e21a63 fate: make lavfi tests output only md5
Instead of saving huge raw files, use the md5: output pseudo-protocol
to calculate the checksum of the file directly.  This is especially
useful when testing on remote targets as it avoids transferring 3.6GB
over the network.

213a4cbb39 Add lavfi-pixfmts LE tests.
The corresponding lavfi-pixfmts BE tests are not yet added, as there
are some bugs in the scaler (scaling rgba, argb, bgra, abgr, yuva420p)
which result in differences with the LE reference, and I cannot
visually check the generated files on BE.

7c1bb9143e Fix lavfi pixdesc test
This test verifies the pixdesc code by comparing the output with and
without a filter which should have no effect on the image.  Since the
available pixel formats depend on the byte order of the machine, a
simple reference checksum is not possible.

The test originally tried to solve this by generating a reference file
on the fly.  The problem with this is that the test framework expects
the reference file in the source tree, and writing to the source tree
is not allowed.

To avoid complicating the test framework, we instead provide two
reference files and select which to use based on the byte order.

c014631461 Update lavfitest reference after commit:
Author: bcoudurier
   Date:   Sat Jul 3 03:11:04 2010 +0000

       Set graph swscale opts before parsing it, that way opts are available
       when auto-adding scalers.

It changed the swscale flags used by the auto-added scalers, and so
the output video.

cec96e8de3 Add some ad-hoc tests for libavfilter.
A patched version of ffmpeg supporting video filters is required for
getting this working; thus make lavfitest is supposed to work only in
the libavfilter repository for now.
