Looks better for some cases, worse for others, overall not much difference.
Its more correct though.

Just some cosmetics & comments, the only functional change
"error_resilience: use s->last_picture for accessing last MVs."
Is so buggy that it needs a full rewrite, guess -1.0 PSNR loss wasnt
enough for ronald to realize there was a problem.

Help debugging, safer.

Add link to official specifications, remove author duplication and
others.

Remove one level of indirection, simplify code.

Remove one level of indirection/improve readability.

Also rename variable "extradata" to "palette" ff_cmap_read_palette()
and extract_header(), more meaningful.

Remove the problematic av_dlog() call

This breaks API and ABI.

Added oggpagesize option for Ogg encoding. Allows setting a preferred page size. When set, if an Ogg stream buffer has enough data, a page is made, instead of filling maximum-size pages.

This for example fixes -t with some frext h264 reference streams.

This fixes some overflow in bright areas and ensures that the maximum brightness level is
mapped to the maximum without cliping and without showing dither patterens in flat max
brightness areas.

Should fix compile on systems missing yasm/nasm.

This should fix behavior introduced by commit
96573c0d. Av_rescale_rnd() is not
lossless so if two timestamps are equal after being rescaled they are
not always actually identical. This patch use av_compare_ts() to get
always a correct result.

Fixes issue 2679.

This patch completes the high bit depth h264 decoding support.
Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).

Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

In high bit depth, the QP values may now be up to (51 + 6*(bit_depth-8)).

In high bit depth the pixels will not be stored in uint8_t like in the
normal case, but in uint16_t. The pixel size is thus 1 in normal bit
depth and 2 in high bit depth.
