Reimar Döffinger c66bd78e3d vf_scale: support PAL8 output by producing BGR8.
While quality is bad, PAL8 support is needed to allow testing some
encoders that only support PAL8 input.

Ronald S. Bultje 28c1115a91 swscale: use 15-bit intermediates for 9/10-bit scaling. 2011-08-12 11:54:25 -07:00
Ronald S. Bultje 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.

Ronald S. Bultje 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.

Ronald S. Bultje 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.

Ronald S. Bultje 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.

Ronald S. Bultje 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).
