2011-12-22Remove unnecessary ternary constructsJohn Koleszar
The code had a number of constructs like (condition)?1:0, which is redundant with C's semantics. In the cases where a boolean operator was used in the condition, simply remove the ternary part. Otherwise adjust the surrounding expression to remove the condition (eg, for rounding up. See pickinter.c and rdopt.c) Change-Id: Icb2372defa3783cf31857d90b2630d06b2c7e1be

2011-12-19remove armv6 files from armv5 buildJohn Koleszar
Make bilinearfilter_arm.c compiled only when HAVE_ARMV6, as its definitions are v6 only. This is normally not a problem for static builds as the file is elided at link time, but this was not being done properly for the --enable-shared --enable-pic build.

Merged multi-resolution motion estimation with regular motion estimation function in order to remove duplicated part. This caused slight changes in multi-resulotion encoder quality & performance. Change-Id: Ib4ecc7acfebfe5eea959b5b91febae6db7b95fd1

2011-12-16Avoid heap allocation of firstpass statsJohn Koleszar
The total_stats, this_frame_stats, and total_left_stats structures were previously create by a heap allocation, despite being of fixed size. These structures were allocated and deallocated during {de,}allocate_compressor_data, which is reinvoked whenever the frame size changes. Unfortunately, this clobbers the total_stats and total_left_stats data. Historically, these were variable size at one time, due to the first pass motion map, which necessitated their being created by a unique heap allocation. However, this bug with the total_stats being clobbered has probably been present since that initial implementation. These structures are instead moved to be stored within the struct twopass_rc directly, rather than being heap allocated separately. Change-Id: I7f9e519e25c58b92969071f0e99fa80307e0682b
2011-12-16Fixed mb_skip_coeff bugScott LaVarnway
When mb_skip_coeff is set, the idct is not necessary. Prior to this patch, the code would call idcts based on leftover eob information. This patch will now skip the idct for SPLIT_MV and clear out the eobs for B_PRED, forcing the idct to be skipped. Change-Id: If5b0d2ed3ebd07789d30ec5160df927485fcaa17
2011-12-15Moved dequant idct into commonScott LaVarnway
These functions are now used by the encoder. This is WIP with the goal of creating a common idct/add for the encoder and decoder. A boost of 1.8% was seen for the HD rt test clip used. [Tero] Added needed changes to ARM side. Change-Id: Ibbb8000be09034203d7adffc457d3c3f8b06a5bf

2011-12-15Only call vp8_find_near_mvs() once for each macroblockYunqing Wang
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. Change-Id: I661394b49c6ad79fed7d0f2eb2be239b9c56f149

2011-12-14add check to ensure that cq_level falls within min and max qJames Berry
Add the notion of deferred validation of parameters. We don't want to validate the cq_level at initialization time, because it won't have been set via set_param() yet. Change-Id: Ia1308395e8c10e0b1dc4e9af3a09b2bd6744cc30

2011-12-07Reduce mem copies in encoder loopfilter level pickingAttila Nagy
Do the test filtering in the existing backup frame buffer instead of the original. Copy the original data into extra buffer before doing the filtering. This way there is no need to restore the original unfiltered frame at the end of level picking process. This came up in some discussions with Johann. Thanks!

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

2011-11-25Modified the inverse walsh to output directlyScott LaVarnway
to the dqcoeff or qcoeff buffer. The encoder would populate the dc coeffs of the y blocks as a separate stage (recon_dcblock) and the decoder would use a special version of the idct. This change eliminates the extra copy and reduces the code footprint. [Tero] Added needed changes to armv6 and NEON assembly. Change-Id: I83202ffdbaf83f6e5dd69f4ba2519fcf0b13b3ba

2011-11-23Fix encoder partitioned output on ARMAttila Nagy
API was not returning correct partition sizes on arm targets. The armv5 token packing functions were not storing the information to the partition size table. As a fix, have one boolcoder instance allocated for each partition so that partition sizes are internally available after all partitions were encoded. This will also allow more flexibility in producing several partitions in parallel. Use buffer validation (overflow check) in all ARM bitpacking functions.
