Two head files dct.h and dct_x86.h were removed in a previous commit, this commit removed the build's dependency on the two files. Change-Id: Idd33712470912d39d42f133dc30b710cab6fa832

This is a code snapshot of experimental work currently ongoing for a next-generation codec. The codebase has been cut down considerably from the libvpx baseline. For example, we are currently only supporting VBR 2-pass rate control and have removed most of the code relating to coding speed, threading, error resilience, partitions and various other features. This is in part to make the codebase easier to work on and experiment with, but also because we want to have an open discussion about how the bitstream will be structured and partitioned and not have that conversation constrained by past work. Our basic working pattern has been to initially encapsulate experiments using configure options linked to #IF CONFIG_XXX statements in the code. Once experiments have matured and we are reasonably happy that they give benefit and can be merged without breaking other experiments, we remove the conditional compile statements and merge them in. Current changes include: * T...

Removal of the pickinter.c and .h files and calls to this code. Removal of some code relating to real time and one pass settings though there is more to be done in this regard. However, vp8_set_speed_features() now only supports modes 0 and 1 and speeds up to 3 so rd should always be set. Change-Id: I62c0c1b6154ab499785baef310536080e87bc4d8

This introduces base functions for introducing implicit segmentation. The code that actually stores the results to the segment map isn't here yet. This just prints out the segmentation map results if you call it. Uses connected component labeling technique on mbmi info so that only if 2 mbs are horizontally or vertically touching do they get the same segment. vp8next - plumbing for rotation code to produce taps for rotation ( tapify. py ), code for predicting using rotation ( predict_rotated.c ) , code for finding the best rotation find_rotation.c. didn't checkin code that uses this in the codec. still work in progress.

This quite large check in includes the following: Merge in some code from Ronald (mbgraph.c) that scans a Gf/arf group. This is used as a basis for a simple segmentation for the normal frames in a gf/arf group. This code also uses satd functions from Yaowu. Adds functionality for coding the latest possible position of an EOB for blocks in the segment. (Currently 0-15 only, hence just for 4x4 dct). Where the EOB position is 0 this acts like "skip" and the normal coding of skip at the per mb level is disabled. Added functions (seg_common.c) for setting and reading segment feature elements. These may want to be optimized away at some point but while the mecahnism is in a state of flux they provide a single location for making changes and keep things a bit cleaner. This is still proof of concept code. Currently the tested feature set:- Quantizer, Loop Filter level, Reference frame, Prediction Mode, EOB end stop. TBD:- Add functions for setting and reading the feature data with range and validity checking. Handling of signed and unsigned feature data. At the moment all is assumed to be signed and a sign bit is coded but many cannot be negative. Correct handling of EOB feature with intra coded blocks. Testing/trapping of legal/illegal ref frame and mode combinations. Transform size switch plus merge and test with 8c8 DCT work Merge and test with Sumans Segmenation coding optimizations Change-Id: Iee12e83661c7abbd1e0ce6810915eb4ec35e2d8e

add an sse4 quantizer so we can use pinsrw/pextrw and keep values in xmm registers instead of proxying through the stack. and as long as we're bumping up, use some ssse3 instructions in the EOB detection (see ssse3 fast quantizer) pick up about a percent on 32bit and about two on 64bit.

This patch cleans up the source buffer storage and copy mechanism to allow access through a standard push/pop/peek interface. This approach also avoids an extra copy in the case where the source is not a multiple of 16, fixing issue #102. Change-Id: I05808c39f5743625cb4c7af54cc841b9b10fdbd9

count can be reduced to short because the max number of filtered frames is set to 15. the max value for any frame is 32 (modifier = 16, filter_weight = 2). 15*32 = 480 which requires 9 bits this function goes from about 7000 us / 1000 iterations for the C code to < 275 us / 1000 iterations for sse2 for block_size = 16 and from about 1800 us / 1000 iters to < 100 us / 1000 iters for block_size = 8 Change-Id: I64a32607f58a2d33c39286f468b04ccd457d9e6e

Instead of doing 8-bit data unpack and 16-bit subtraction, use psubb to do 16 8-bit subtractions and pcmpgtb to preserve the sign information. This does not bring noticable gain since these functions are not called frequently. Change-Id: I90a0dfaa3db9d422e4ada324076596ffb178548e

Remove the dependency on postproc.c for the encoder in general, the only unchecked need for it is when CONFIG_PSNR is enabled. All other cases are already wrapped in CONFIG_POSTPROC. In the CONFIG_PSNR case the file will still be included. Additionally, when VP8_SET_POSTPROC is used with the encoder when post processing has been disabled an error will be returned. This addresses issue #153. Change-Id: Ia6dfe20167f7077734a6058cbd1d794550346089

ssim.c comiles in a huge (512M) amount of global scratch space. Allocating this data on the heap would be a better solution, but this file doesn't need to be built at all in most cases, so as a first pass, disable it except when doing opsnr.stt output (--enable-psnr).

This patch adds support for building shared libraries when configured with the --enable-shared switch. Building DLLs would require more invasive changes to the sample utilities than I want to make in this patch, since on Windows you can't use the address of an imported symbol in a static initializer. The best way to work around this is proably to build the codec interface mapping table with an init() function, but dll support is of questionable value anyway, since most windows users will probably use a media framework lib like webmdshow, which links this library in staticly.
