2011-02-08clean up bilinear filterJohann
make reference version of bilinear_filters short. use reference versions of bilinear_filters and sub_pel_filters when possible. recognize that Width was being passed into filter_block2d_bil_first_pass multiple times. ARM version had already fixed this. propegate to C. change references to src_pixels_per_line to src_pitch and standardize on src/dst (instead of input/output). recognize that first_pass is only run in the verticle and second_pass only horizontal. ARM version had already fixed this. propegate to C Change-Id: I292d376d239a9a7ca37ec2bf03cc0720606983e2

2011-01-28Adds "armvX-none-rvct" targetsTero Rintaluoma
Adds following targets to configure script to support RVCT compilation without operating system support (for Profiler or bare metal images). - armv5te-none-rvct - armv6-none-rvct - armv7-none-rvct To strip OS specific parts from the code "os_support"-config was added to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS specific parts such as OS specific includes and function calls for timers and threads etc. This was done to enable RVCT compilation for profiling purposes or running the image on bare metal target with Lauterbach. Removed separate AREA directives for READONLY data in armv6 and neon assembly files to fix the RVCT compilation. Otherwise "ldr <reg>, =label" syntax would have been needed to prevent linker errors. This syntax is not supported by older gnu assemblers. Change-Id: I14f4c68529e8c27397502fbc3010a54e505ddb43

2011-01-19experiment extending the quantizer rangeYaowu Xu
Prior to this change, VP8 min quantizer is 4, which caps the highest quality around 51DB. This experimental change extends the min quantizer to 1, removes the cap and allows the highest quality to be around ~73DB, consistent with the fdct/idct round trip error. To test this change, at configure time use options: --enable-experimental --enable-extend_qrange The following is a brief log of changes in each of the patch sets patch set 1: In this commit, the quantization/dequantization constants are kept unchanged, instead scaling factor 4 is rolled into fdct/idct. Fixed Q0 encoding tests on mobile: Before: 9560.567kbps Overall PSNR:50.255DB VPXSSIM:98.288 Now: 18035.774kbps Overall PSNR:73.022DB VPXSSIM:99.991 patch set 2: regenerated dc/ac quantizer lookup tables based on the scaling factor rolled in the fdct/idct. Also slightly extended the range towards the high quantizer end. patch set 3: slightly tweaked the quantizer tables and generated bits_per_mb table based on Paul's suggestions. patch set 4: fix a typo in idct, re-calculated tables relating active max Q to active min Q patch set 5: added rdmult lookup table based on Q patch set 6: fix rdmult scale: dct coefficient has scaled up by 4 patch set 7: make transform coefficients to be within 16bits patch set 8: normalize 2nd order quantizers patch set 9: fix mis-spellings patch set 10: change the configure script and macros to allow experimental code to be enabled at configure time with --enable-extend_qrange patch set 11: rebase for merge Change-Id: Ib50641ddd44aba2a52ed890222c309faa31cc59c
2011-01-19Merge "Implement error tracking in the decoder"John Koleszar
2011-01-19Implement error tracking in the decoderHenrik Lundin
A new vpx_codec_control called VP8D_GET_FRAME_CORRUPTED. The output from the function is non-zero if the last decoded frame contains corruption due to packet losses. The decoder is also modified to accept encoded frames of zero length. A zero length frame indicates to the decoder that one or more frames have been completely lost. This will mark the last decoded reference buffer as corrupted. The data pointer can be NULL if the length is zero. Change-Id: Ic5902c785a281c6e05329deea958554b7a6c75ce

2011-01-07CQ ModePaul Wilkins
The merge includes hooks to for CQ mode and other code changes merged from the test branch. CQ mode attempts to maintain a more stable quantizer within a clip whilst also trying to adhere to a guidline maximum bitrate. The existing target data rate parameter is used to specify the guideline maximum bitrate. A new parameter allows the user to specify a target CQ level. For normal (non kf/gf/arf) frames, the quantizer will not drop BELOW the user specified value (0-63). However, in some cases the encoder may choose to impose a target CQ that is above that specified by the user, if it estimates that consistent use of the target value is not compatible with guideline maximum bitrate.

2010-12-17Add psnr/ssim tuning optionJohn Koleszar
Add a new encoder control, VP8E_SET_TUNING, to allow the application to inform the encoder that the material will benefit from certain tuning. Expose this control as the --tune option to vpxenc. The args helper is expanded to support enumerated arguments by name or value. Two tunings are provided by this patch, PSNR (default) and SSIM. Activity masking is made dependent on setting --tune=ssim, as the current implementation hurts speed (10%) and PSNR (2.7% avg, 10% peak) too much for it to be a default yet.

2010-11-18remove low pass filtering from two 4x4 intra predictionYaowu Xu
In the process of developing new intra prediction modes, tests have shown removal of the low pass filtering from B_HE_PRED and B_VE_PRED has an overall minor positive impact in both PSNR and SSIM metric. Overall difference is about 0.1%. The change shall also have a small positive impact on speed. Intuitively, this change should also reduce some of the tendency of "flattening" Change-Id: I3c43b0daca833c6eff77d00f19c811f9ef9368a3
