2011-01-21Merge "Modify sub-pixel filters to eliminate unnecessary calculations"Yunqing Wang
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
2011-01-20Update configure scriptsAttila Nagy

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

2011-01-19experiment 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

2011-01-19First pass loop bug.Paul Wilkins
Incorrect value loop_decay_rate used in GF loop. The intent was to test the cumulative value decay_accumulator. Change-Id: I62928c63eb09f4f6936a45ebd1c23784d1c9681b
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

2011-01-18Further CQ, Key frame and ARF changesPaul Wilkins
This code fixes a bug in the calculation of the minimum Q for alt ref frames. It also allows an extended gf/arf interval for sections of clips that completely static (or nearly so). Change-Id: I1a21aaa16d4f0578e5f99b13bebd78d59403c73b

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

2011-01-14Merge "Experimental change to help with ARNR problem."Paul Wilkins
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.

2011-01-14ARNR filter pointer update bug fixAdrian Grange
In cases where the frame width is not a multiple of 16 the ARNR filter would go wrong. In vp8_temporal_filter_iterate_c when updating pointers at the end of a row of MBs, the image size was incorrectly used rather than using Num_MBs_In_Row times 16 (Y) or 8 (U,V). This worked when width is multiple of 16 but failed otherwise. Change-Id: I008919062715bd3d17c7aa2562ab58d1cb37053a

2011-01-14KF/GF PulsingPaul Wilkins
This change is designed to try and reduce pulsing effects when moving with a complex transition like a fade, into an easy or static section in an otherwise difficult clip in CQ mode. The active CQ level is relaxed down to the user entered level for frames that are generating less than the passed in minimum bandwidth. Change-Id: Id6d8b551daad4f489c087bd742bc95418a95f3f0

Where a key frame occurs because of a minimum interval selected by the user, then these forced key frames ideally need to be more closely matched in quality to the surrounding frame. Change-Id: Ia55b1f047e77dc7fbd78379c45869554f25b3df7
