2012-01-20Overhauling the thresholds and mixing proportions for mfqe postprocessor.Deb Mukherjee
Makes the thresholds for the multiframe quality enhancement module depend on the difference between the base quantizers. Also modifies the mixing function to weigh the current low quality frame less if the difference in quantizer is large. With the above modifications mfqe works well for both scalable patterns as well as low quality key frames. Change-Id: If24e94f63f3c292f939eea94f627e7ebfb27cb75
2012-01-17Modifying the base q propagation in the mfqe post processingDeb Mukherjee
filter in a way such that when there is a single bad frame, the post-processing is applied not only to just that frame but a few subsequent frames as well. Change-Id: Iba5d9896eed77244eb76b4a74692a93f8ecff634
2012-01-10Allowing the mfqe post-processing filter to be used in conjunctionDeb Mukherjee
with deblock or demacroblock filters. When --mfqe is used together with --demacroblock or --deblock, mfqe is applied first and then demacroblock/deblock is applied to the mfqe result. Change-Id: Id83ee01f1b4a33a116f071dcf26d59c7f3497c32

2012-01-06Reduced the size of Y1Dequant and friends to [128][2]Scott LaVarnway
This patch removes the local copies of the dequantize constants and implements John's idea as described in "Make a local copy of the dequantized data" commit. Change-Id: Ic6b7d681f00bf63263f71ff1e39ab2f80729e8b2
2012-01-05Multiframe quality enhancement postprocessingDeb Mukherjee
Adds a multiframe postprocessing module to enhance the quality of certain frames that are coded at lower quality than preceding frames. The module can be invoked from the commandline by use of the --mfqe option, and will be most beneficial for enhancing the quality of frames decoded using scalable patterns. Uses the vp8_variance_var16x16 and vp8_variance_sad16x16 function pointers to compute SAD and Variance of blocks. Change-Id: Id73d2a6e3572d07f9f8e36bbce00a4fc5ffd8961

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

2011-12-15Moved dequant idct into commonScott LaVarnway

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

2011-11-11avoid 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().

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
