2012-05-22Move all tests to test/ directoryJohn Koleszar
Consolodate the unit tests under vp8/ to the test/ directory Change-Id: I6d6a0fb60f5e3874a4d6710e9e121dd3e81a93db
2012-05-22Build unit tests monolithicallyJohn Koleszar
Rework unit tests to have a single executable rather than many, which should avoid pollution of the visual studio project namespace, improve build times, and make it easier to use the gtest test sharding system when we get these going on the continuous build cluster.

2012-05-08vp8e - boolcoder unit testJim Bankoski
Adds a unit test to the boolcoder that tests encoding and decoding thousands of different bits, with different probabilities in different patterns. Code borrowed from the webp project - and its committers. Change-Id: Icabbb884d57e666496490c961dd29b246144ab3e
2012-05-04Formalize encodeframe.c forward delclarationsJohn Koleszar
Change If4321cc5 fixed a bug caused by forward declarations not being kept in sync across C files, resulting in a function call with the wrong arguments. The commit moves the affected function declarations into a header file, along with the other symbols from encodeframe.c that were being sloppily shared.

2012-05-04Make global data constAttila Nagy
Removes all runtime initialization of global data. This commit is a squashed version of the following series cherry-picked from master. This is necessary because of a change that was merged to the tester that depends on the scaler being moved to the RTCD framework, which is a worthwhile thing to include in Eider anyway. - a91b42f02 Makes all global data in entropy.c const - b35a0db0e Makes all global data in tokenize.c const - 441cac8ea Makes all mode token tables const - 5948a0210 Ports vpx_xcaler to new RTCD method - 317d4244c Makes all mode token tables const part 2 Change-Id: Ifeaea24df2b731e7c509fa6c6ef6891a374afc26
2012-04-17Makes all global data in tokenize.c constAttila Nagy
Removes all runtime initialization of global data in tokenize.c. DCT token and cost tabels are pre-generated. Second patch in a series to make sure code is reentrant. Change-Id: Iab48b5fe290129823947b669413101f22a1bcac0
2012-03-15WebM Experimental Codec Branch SnapshotYaowu Xu
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: * Temporal coding experiment for segments (though still only 4 max, it will likely be increased). * Segment feature experiment - to allow various bits of information to be coded at the segment level. Features tested so far include mode and reference frame information, limiting end of block offset and transform size, alongside Q and loop filter parameters, but this set is very fluid. * Support for 8x8 transform - 8x8 dct with 2nd order 2x2 haar is used in MBs using 16x16 prediction modes within inter frames. * Compound prediction (combination of signals from existing predictors to create a new predictor). * 8 tap interpolation filters and 1/8th pel motion vectors. * Loop filter modifications. * Various entropy modifications and changes to how entropy contexts and updates are handled. * Extended quantizer range matched to transform precision improvements. There are also ongoing further experiments that we hope to merge in the near future: For example, coding of motion and other aspects of the prediction signal to better support larger image formats, use of larger block sizes (e.g. 32x32 and up) and lossless non-transform based coding options (especially for key frames). It is our hope that we will be able to make regular updates and we will warmly welcome community contributions. Please be warned that, at this stage, the codebase is currently slower than VP8 stable branch as most new code has not been optimized, and even the 'C' has been deliberately written to be simple and obvious, not fast. The following graphs have the initial test results, numbers in the tables measure the compression improvement in terms of percentage.

2011-12-05Multiple-resolution encoderYunqing Wang
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! Change-Id: I03be9a51167eddf94399f92d269599fb3f3d54f5

2011-04-21keep values in registers during quantizationJohann
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.

2011-04-13Refactor lookahead ring bufferJohn Koleszar
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

2011-03-08Write SSSE3 sub-pixel filter functionYunqing Wang
1. Process 16 pixels at one time instead of 8. 2. Add check for both xoffset =0 and yoffset=0, which happens during motion search. This change gave encoder 1%~3% performance gain. Change-Id: Idaa39506b48f4f8b2fbbeb45aae8226fa32afb3e

2011-01-06x86 sse2 temporal_filter_applyJohann
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

2010-10-18Add SSE2 subtract functionsYunqing Wang
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
2010-09-09Use WebM in copyright notice for consistencyJohn Koleszar
Changes 'The VP8 project' to 'The WebM project', for consistency with other webmproject.org repositories. Fixes issue #97. Change-Id: I37c13ed5fbdb9d334ceef71c6350e9febed9bbba
2010-09-02encoder: remove postproc dependencyJames Zern
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
2010-08-13move segmentation_common to encoderJohn Koleszar
vp8_update_gf_useage_maps() is only used by the encoder. This patch fixes the ability to build in decode-only or encode-only configurations. Change-Id: I3a5211428e539886ba998e09e8abd747ac55c9aa
2010-07-22msvs: fix install of codec sourcesJohn Koleszar

2010-06-24Redo the forward 4x4 dctYaowu Xu
The new fdct lowers the round trip sum squared error for a 4x4 block ~0.12. or ~0.008/pixel. For reference, the old matrix multiply version has average round trip error 1.46 for a 4x4 block. Thanks to "derf" for his suggestions and references. Change-Id: I5559d1e81d333b319404ab16b336b739f87afc79

2010-06-14sse2 version of vp8_regular_quantize_bScott LaVarnway
Added sse2 version of vp8_regular_quantize_b which improved encode performance(for the clip used) by ~10% for 32 bit builds and ~3% for 64 bit builds. Also updated SHADOW_ARGS_TO_STACK to allow for more than 9 arguments. Change-Id: I62f78eabc8040b39f3ffdf21be175811e96b39af
2010-06-11require --enable-psnr to build ssimJohn Koleszar
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).

2010-06-05shared library support (.so)John Koleszar
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.

2010-05-24install includes in DIST_DIR/include/vpx, move vpx_codec/ to vpx/John Koleszar
This renames the vpx_codec/ directory to vpx/, to allow applications to more consistently reference these includes with the vpx/ prefix. This allows the includes to be installed in /usr/local/include/vpx rather than polluting the system includes directory with an excessive number of includes.
