2011-01-28Inconsistent distortion metric in vp8_rd_pick_intra_mbuv_modePaul Wilkins
This function was using a variance metric compared to and SSE metric in other places (eg. vp8_rd_inter_uv) Change-Id: I9109fcc5a13bca9db1d7ead500fe14999ab233eb

2011-01-26Rationalize vp8_rd_pick_intra16x16mby_mode()Paul Wilkins
Use the function macro_block_yrd() to calculate error and distortion in keeping with what is done for inter frames. The old code was using a variance metric for once case and an SSE function for measuring distortion in the other case. The function vp8_encode_intra16x16mbyrd() is no longer used.

2011-01-26Correction to buffer update for non-viewable frames.Paul Wilkins
The code previously tested cpi->common.refresh_alt_ref_frame but there are situations where this flag may be set for viewable frames. The correct test should be !cm->show_frame. Change-Id: Ia1a600622992a4a68fe1d38ac23bf6b34b133688

2011-01-25cap the best quantizer for 2nd order DCYaowu Xu
This commit also removes artificial RDMULT cap for low quantizers. The intention is to address some abnormal behavior of mode selections at the low quantizer end, where many macroblocks were coded with SPLITMV with all partitions using same motion vector including (0,0). This change improves the compression quality substantially for high quality encodings in both PSNR and SSIM terms. Overall effect on mid/low rate range is also positive for all metrics, but smaller in magnitude. Change-Id: I864b29c4bd9ff610d2545fa94a19cc7e80c02667

2011-01-25Merge "Incorrect bit allocation in forced KF groups."Paul Wilkins
2011-01-25Incorrect bit allocation in forced KF groups.Paul Wilkins
The old 2 pass code estimated error distribution when coding a forced (by interval) key frame. The result of this was that in some cases, when allocating bits at the GF group level within a KF group there was either a glut of bits or starvation of bits at the end of the KF group. Added code to rescan and get the correct data once the position of a forced key frame has been determined. Change-Id: I0c811675ef3f9e4109d14bd049d7641682ffcf11

2011-01-24Added vp8_update_zbin_extraScott LaVarnway
vp8cx_mb_init_quantizer was being called for every mode checked in vp8_rd_pick_inter_mode. zbin_extra is the only value that really needs to be recalculated. This calculation is disabled when using the fast quantizer for mode selection. This gave a small performance boost (~.5% to 1%). Note: This needs to be verified with segmentation_enabled.

2011-01-21Modify sub-pixel filters to eliminate unnecessary calculationsYunqing Wang
In sub-pixel calculation, xoffset and yoffset mostly take some specific values. Modified sub-pixel filter functions according to these possible values to improve performance. Change-Id: I83083570af8b00ff65093467914fbb97a4e9ea21
2011-01-21Modified static scene check.Paul Wilkins
Added code to scan ahead a few frames when we see what we think is a static scene in the two pass GF loop to see if the conditions persist. Moved calculation of decay rate out into a fuunction. Change-Id: I6e9c67e01ec9f555144deafc8ae67ef25bffb449
2011-01-20Further work to reduce pulsing.Paul Wilkins
These changes are specifically targeted at fade transitions to static scenes. Here we want to place a GF/ARF immediately after the fade and prevent an ARF just before the fade. Also some code lines and comment lines shortened to 80 chars while I was there. Change-Id: Iefdc09a4fa7b265048fc017246b73e138693950f

2011-01-20Fixed use of motion percentage in KF/GF group calcAdrian Grange
In both vp8_find_next_key_frame and define_gf_group, motion_pct was initialised at the top of the loop before next_frame stats had been read in. This fix sets motion_pct after next_frame stats have been read. Change-Id: I8c0bebf372ef8aa97b97fd35b42973d1d831ee73

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

2011-01-17Fix CQ range and experimental KF sizing changes.Paul Wilkins
The CQ level was not using the q_trans[] array to convert to a 0-127 range as per min and maxq Experimental change to try and match the reconstruction error for forced key frames approximately to that of the previous frame by means of the recode loop. Though this may cause extra recodes and the recode behavior has not been optimized, it can only happen on forced key frames. Change-Id: I1f7e42d526f1b1cb556dd461eff1a692bd1b5b2f

2011-01-14Testing of modes with Alt Ref framePaul Wilkins
Previously when a frame was being overlaid on a previously coded alt ref frame we only checked the alt ref 0,0 mode. Where there is a possibility that the alt ref buffer is a filtered frame we should allow the other prediction modes as normal or at the least allow use of the last frame buffer.
