Change-Id: Iae406d16fab5bace47fbcf5ef7ed021f08af159d
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

2011-12-05Multiple-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
2011-11-28Merge "Modified the inverse walsh to output directly"Scott LaVarnway
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

2011-11-11avoid resetting framerate during vpx_codec_enc_config_set()John Koleszar
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().

2011-11-09Relocated idct/add calls for encoderScott LaVarnway
Call the idct/add after the tokenize. This is WIP with the goal of creating a common idct/add for the encoder and decoder. This move is necessary because the decoder's version of the idct clobbers qcoeff, which is used by the tokenize. Change-Id: I6b08d8e8397cd873647fa4fb9469884e3c876756

2011-11-03Change use of eob in the encoderTero Rintaluoma
Changed 'int eob' to 'char *eob' in BLOCKD so that both encoder and decoder will use eobs[25] array from MACROBLOCKD structure. In future, this will enable use of the decoder side IDCT in the encoder. Change-Id: I6e1c011628cb8864fd4a0b80f0279ce16a5ca978
2011-11-01Changing decoder input partition API to input fragments.Stefan Holmer
Adding support for several partitions within one input fragment. This is necessary to fully support all possible packetization combinations in the VP8 RTP profile. Several partitions can be transmitted in the same packet, and they can only be split by reading the partition lengths from the bitstream. Change-Id: If7d7ea331cc78cb7efd74c4a976b720c9a655463

2011-10-26Reduce partial frame copy in encoder's pick_filter_level_fastAttila Nagy
The partial frame copy function used to copy an extra 8 lines above and below. The partial frame filtering can only modify 3 pixel rows above the partial frame. Reduce copy to bare minimum needed, which is 4 lines, so that partial filtering on copied frame is possible. Define the "magic" fraction number for partial filtering in loopfilter.h .

2011-10-20Fix: check cx_data buffer prior to writeJames Berry
check to make sure that cx_data buffer has enough room before writting to it, prior behavior did not which could result in a crash. Change-Id: I3fab6f2bc4a96d7c675ea81acd39ece121738b28
2011-10-18Remove usage of predict buffer for decodeScott LaVarnway
Instead of using the predict buffer, the decoder now writes the predictor into the recon buffer. For blocks with eob=0, unnecessary idcts can be eliminated. This gave a performance boost of ~1.8% for the HD clips used. Tero: Added needed changes to ARM side and scheduled some assembly code to prevent interlocks. Patch Set 6: Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3) into this commit because of similarities in the idct functions. Patch Set 7: EC bug fix.

2011-10-11Added rate-targeted temporal scalabilityAdrian Grange
Added the ability to create rate-targeted, temporally scalable, VP8 compatible bitstreams. The application vp8_scalable_patterns.c demonstrates how to use this capability. Users can create output bitstreams containing upto 5 temporally separable streams encoded as a single VP8 bitstream. (previously abandoned as: I92d1483e887adb274d07ce9e567e4d0314881b0a) Change-Id: I156250a3fe930be57c069d508c41b6a7a4ea8d6a

2011-09-30combine loopfilter data accessJohann
The data processed by the loopfilter overlaps. At the block level, this results in some redundant transforms. Grouping the filtering allows for a single 16x16 transpose (and inversion) instead of three 16x8 transposes (and three more inversions). This implementation is x86_64 only. We retain the previous implementation for x86. Improvements are obviously material dependant, but it seems to be ~%1 in tests here. Change-Id: I467b7ec3655be98fb5f1a94b5d145e5e5a660007

2011-09-16clamp_mvs() using the wrong motion vector informationScott LaVarnway
In the "Removed bmi copy to/from BLOCKD" commit, the copy to the bmi in BLOCKD was eliminated. The clamp_mvs() used the bmi in BLOCKD, which now contains incorrect values. This patch fixes this problem. Change-Id: I8eca1eaf4015052b0b63e90876f7ad321aba7cff

for SPLITMV and B_PRED modes. Modified code to use the bmi found in mode_info_context instead of BLOCKD. On the decode side, the uvmvs are calculated only when required, instead of every macroblock. This is WIP. (bmi should eventually be removed from BLOCKD) Small performance gains noticed for RT encodes and decodes.(VGA) Change-Id: I2ed7f0fd5ca733655df684aa82da575c77a973e7

2011-08-23Fix data accesses for simple loopfiltersJohann
The data that the simple horizontal loopfilter reads is aligned, treat it accordingly. For the vertical, we only use the bottom 4 bytes, so don't read in 16 (and incur the penalty for unaligned access). This shows a small improvement on older processors which have a significant penalty for unaligned reads. postproc_mmx.c is unused Change-Id: I87b29bbc0c3b19ee1ca1de3c4f47332a53087b3d

2011-08-19Merge "Copy less when active map is in use"John Koleszar
2011-08-19Copy less when active map is in useAlpha Lam
When active map is specified and the current frame is not a key frame, golden frame nor a altref frame then copy only those active regions. This significantly reduces encoding time by as much as 19% on the test system where realtime encoding is used. This is particularly useful when the frame size is large (e.g. 2560x1600) and there's only a few action macroblocks. Change-Id: If394a813ec2df5a0201745d1348dbde4278f7ad4
