1161055129 Be consistent with SAD values
SAD returns unsigned values. Make all the declarations the same.

Remove bestsad initialization and check. It is always set to the
result of a SAD call so it will never remain UINT_MAX

Use ja instead of jg to test unsigned comparison instead of signed.

Update test.

0164a1cc5b Fix pedantic compiler warnings
Allows building the library with the gcc -pedantic option, for improved
portabilty. In particular, this commit removes usage of C99/C++ style
single-line comments and dynamic struct initializers. This is a
continuation of the work done in commit 97b766a46, which removed most
of these warnings for decode only builds.

b41c17d625 Shares one set of RD costs tables between all encoding threads
RD costs were local to MACROBLOCK data and had to be copied all the
time to each thread's MACROBLOCK data. Tables moved to a common place
and only pointers are setup for each encoding thread.

vp8_cost_tokens() generates 'int' costs so changed all types to be
int (i.e. removed unsigned).

NOTE: Could do some more cleaning in vp8cx_init_mbrthread_data().

019384f2d3 Only do uv intra-mode evaluation when intra mode is checked
When we encode slide-show clips, for the majority of the time,
only ZEROMV mode is checked, and all other modes are skipped.
This change delayed uv intra-mode evaluation until intra mode is
actually checked. This gave big performance gain for slide-show
video encoding (2nd pass gain: 18% to 28%). But, this change
doesn't help other types of videos.

Also, zbin_mode_boost is adjusted in mode-checking loop, which
causes bitstream mismatch before/after this change when --best
or --good with --cpu-used=0 are used.

In vp8_rd_pick_inter_mode(), if total of eobs is zero, rate needs
to be adjusted since there are no non-zero coefficients for
transmission. The uv intra eobs calculated in
rd_pick_intra_mbuv_mode() need to be saved before they are
overwritten by inter-mode eobs.

83cef816fd Correct clamping in use of vp8_find_near_mvs()
Commit e06c242ba introduced a change to call vp8_find_near_mvs() only
once instead of once per reference frame by observing that the only
effect that the frame had was on the bias applied to the motion
vector. By keeping track of the sign_bias value, the mv to use could
be flip-flopped by multiplying its components by -1.

This behavior was subtley wrong in the case when clamping was applied
to the motion vectors found by vp8_find_near_mvs(). A motion vector
could be in-bounds with one sign bias, but out of bounds after
inverting the sign, or vice versa. The clamping must match that done
by the decoder.

This change modifies vp8_find_near_mvs() to remove the clamping from
that function. The vp8_pick_inter_mode() and vp8_rd_pick_inter_mode()
functions instead track the correctly clamped values for both bias
values, switching between them by simple assignment. The common
clamping and inversion code is in vp8_find_near_mvs_bias()

Otherwise adjust the surrounding expression to remove the condition

e06c242baa Only call vp8_find_near_mvs() once for each macroblock
While doing motion search on a macroblock, we usually call
vp8_find_near_mvs once per reference frame. Actually, for
different reference frames, the only difference in calculating
these near_mvs is they may have different sign_bias, which
causes a sign change in resulting near_mvs. In this change, we
only do find_near_mvs for the first reference frame. For other
reference frames, only need to adjust the near_mvs according to
that reference frame's sign_bias value.

aa7335e610 Multiple-resolution encoder
The example encoder down-samples the input video frames a number of
times with a down-sampling factor, and then encodes and outputs
bitstreams with different resolutions.

Support arbitrary down-sampling factor, and down-sampling factor
can be different for each encoding level.

For example, the encoder can be tested as follows.
1. Configure with multi-resolution encoding enabled:
../libvpx/configure --target=x86-linux-gcc --disable-codecs
--enable-vp8 --enable-runtime_cpu_detect --enable-debug
--disable-install-docs --enable-error-concealment
--enable-multi-res-encoding
2. Run make
3. Encode:
If input video is 1280x720, run:
./vp8_multi_resolution_encoder 1280 720 input.yuv 1.ivf 2.ivf 3.ivf 1
(output: 1.ivf(1280x720); 2.ivf(640x360); 3.ivf(320x180).
The last parameter is set to 1/0 to show/not show PSNR.)
4. Decode:
./simple_decoder 1.ivf 1.yuv
./simple_decoder 2.ivf 2.yuv
./simple_decoder 3.ivf 3.yuv
5. View video:
mplayer 1.yuv -demuxer rawvideo -rawvideo w=1280:h=720 -loop 0 -fps 30
mplayer 2.yuv -demuxer rawvideo -rawvideo w=640:h=360 -loop 0 -fps 30
mplayer 3.yuv -demuxer rawvideo -rawvideo w=320:h=180 -loop 0 -fps 30

The encoding parameters can be modified in vp8_multi_resolution_encoder.c,
for example, target bitrate, frame rate...

Modified API. John helped a lot with that. Thanks!

e55974bf86 Speed selection support for disabled reference frames
There was an implicit reference frame test order (typically LAST,
GOLD, ARF) in the mode selection logic, but this doesn't provide the
expected results when some reference frames are disabled. For
instance, in real-time mode, the speed selection logic often disables
the ARF modes. So if the user disables the LAST and GOLD frames, the
encoder was always choosing INTRA, when in reality searching the ARF
in this case has the same speed penalty as searching LAST would have
had.

Instead, introduce the notion of a reference frame search order. This
patch preserves the former priorities, so if a frame is disabled, the
other frames bump up a slot to take its place. This patch lays the
groundwork for doing something smarter in the frame test order, for
example considering temporal distance or looking at the frames used by
nearby blocks.

bdd35c13cc avoid resetting framerate during vpx_codec_enc_config_set()
The calculated frame_rate is a state variable in the codec, and
shouldn't be maintained in the configuration struct. Move it to the
main part of cpi so that it isn't clobbered when the configuration
struct is updated. The initial framerate estimate is moved from the
vp8_cx_iface.c wrapper into the body of init_config() in onyx_if.c, so
that it is only called once and not reset on every call to
vp8_change_config().
