2013-10-14Move token_cache from cost_coeffs to MACROBLOCKJingning Han
This commit moves token_cache buffer into macroblock struct, instead of defining as a local variable in cost_coeffs. This avoids repeatedly re-allocating memory space in the rate-distortion optimization loop. The runtime at speed 0 reduces: bus 2000kbps, 161692ms to 159951ms football 600kbps, 229505ms to 225821ms Change-Id: If7da6b0b6d8c5138a16271a33c4548fba33d8840

2013-10-11Change in rddiv parameter to make it a power of 2Deb Mukherjee
Converts the constant rddiv parameter to 128 (from 100) and implements RDCOST with bit-shift rather than multiplication. Other parameters are also adjusted to roughly keep the same balance between Rate and Distortion. There is a slight speed-up of about 0.5-1% (at speed 0) as testted on football_cif. There is a slight change in performance due to small change in the parameters. derfraw300: +0.033% stdhdraw250; +0.102% Change-Id: I70ac69f58fa71c83108f68fe41796cd19d1fc760

2013-10-11Experimental rate control change.Paul Wilkins
When the codec in VBR (or cq) mode hits its max q limits and is struggling to hit a target bandwidth, the bit target per frame collapses. In the first instance normal frames cap out at the maximum allowed Q and then the ARF and GFs do the same. This latter behavior is not generally desirable as GFs and ARFs are only effective from a quality and data rate perspective if they have at lease some level of -Q delta compared to the surrounding frames. In this patch I define a separate max Q for GFs and ARFs that is derived from but somewhat lower than that defined for normal frames. In effect there is a minimum Q delta that will always be available for GFs and ARFs regardless of the target rate and MAXQ setting. This may of course mean that the absolute lowest rate obtainable for a given clip is somewhat higher. Change-Id: I268868b28401900d0cd87e51e609cd3b784ab54a

To ensure fast encoding/decoding on devices without ssse3 support, SSE2 optimization of sub-pixel filters was done. Test using 1080p clip showed the decoder speeds were ~70fps with ssse3 filters, ~60fps with sse2 filters, and ~15fps with c filters. Change-Id: Ie2088f87d83a889fba80a613e4d0e287aadd785c

2013-10-10Re-design rate-distortion cost tracking buffersJingning Han
This commit re-designs the per transformed block rate-distortion costs tracking buffers. It removes redundant buffer usage, makes the needed context memory allocation per VP9_COMP instance and reuses the same buffer sets inside the rate-distortion optimization search loop, thereby avoiding repeatedly requiring memory space. It reduces speed 0 runtime: bus at 2000 kbps from 166763ms to 158967ms, football at 600 kbps from 246614ms to 234257ms. Both about 5% speed-up. Local tests suggest about 2% to 5% speed-up for speed 1 and 2 settings. This does not change compression performance. Change-Id: I363514c5276b5cf9a38c7251088ffc6ab7f9a4c3
