v3.4.0
fc430c57 · ·Release v3.4.0 Fluttershy 2022-06-17 v3.4.0 This release includes compression efficiency and perceptual quality improvements, speedup and memory optimizations, and some new features. There are no ABI or API breaking changes in this release. - New Features * New --dist-metric flag with "qm-psnr" value to use quantization matrices in the distortion computation for RD search. The default value is "psnr". * New command line option "--auto-intra-tools-off=1" to make all-intra encoding faster for high bit rate under "--deltaq-mode=3" mode. * New rate control library aom_av1_rc for real-time hardware encoders. Supports CBR for both one spatial layer and SVC. * New image format AOM_IMG_FMT_NV12 can be used as input to the encoder. The presence of AOM_IMG_FMT_NV12 can be detected at compile time by checking if the macro AOM_HAVE_IMG_FMT_NV12 is defined. * New codec controls for the encoder: o AV1E_SET_AUTO_INTRA_TOOLS_OFF. Only in effect if --deltaq-mode=3. o AV1E_SET_RTC_EXTERNAL_RC o AV1E_SET_FP_MT. Only supported if libaom is built with -DCONFIG_FRAME_PARALLEL_ENCODE=1. o AV1E_GET_TARGET_SEQ_LEVEL_IDX * New key-value pairs for the key-value API: o --auto-intra-tools-off=0 (default) or 1. Only in effect if --deltaq-mode=3. o --strict-level-conformance=0 (default) or 1 o --fp-mt=0 (default) or 1. Only supported if libaom is built with -DCONFIG_FRAME_PARALLEL_ENCODE=1. * New aomenc options (not supported by the key-value API): o --nv12 - Compression Efficiency Improvements * Correctly calculate SSE for high bitdepth in skip mode, 0.2% to 0.6% coding gain. * RTC at speed 9/10: BD-rate gain of ~4/5% * RTC screen content coding: many improvements for real-time screen at speed 10 (quality, speedup, and rate control), up to high resolutions (1080p). * RTC-SVC: fixes to make intra-only frames work for spatial layers. * RTC-SVC: quality improvements for temporal layers. * AV1 RT: A new passive rate control strategy for screen content, an average of 7.5% coding gain, with some clips of 20+%. The feature is turned off by default due to higher bit rate variation. - Perceptual Quality Improvements * RTC: Visual quality improvements for high speeds (9/10) * Improvements in coding quality for all intra mode - Speedup and Memory Optimizations * ~10% speedup in good quality mode encoding. * ~7% heap memory reduction in good quality encoding mode for speed 5 and 6. * Ongoing improvements to intra-frame encoding performance on Arm * Faster encoding speed for "--deltaq-mode=3" mode. * ~10% speedup for speed 5/6, ~15% speedup for speed 7/8, and ~10% speedup for speed 9/10 in real time encoding mode * ~20% heap memory reduction in still-picture encoding mode for 360p-720p resolutions with multiple threads * ~13% speedup for speed 6 and ~12% speedup for speed 9 in still-picture encoding mode. * Optimizations to improve multi-thread efficiency for still-picture encoding mode. - Bug Fixes * b/204460717: README.md: replace master with main * b/210677928: libaom disable_order is surprising for max_reference_frames=3 * b/222461449: -DCONFIG_TUNE_BUTTERAUGLI=1 broken * b/227207606: write_greyscale writes incorrect chroma in highbd mode * b/229955363: Integer-overflow in linsolve_wiener * https://crbug.com/aomedia/2032 * https://crbug.com/aomedia/2397 * https://crbug.com/aomedia/2563 * https://crbug.com/aomedia/2815 * https://crbug.com/aomedia/3009 * https://crbug.com/aomedia/3018 * https://crbug.com/aomedia/3045 * https://crbug.com/aomedia/3101 * https://crbug.com/aomedia/3130 * https://crbug.com/aomedia/3173 * https://crbug.com/aomedia/3184 * https://crbug.com/aomedia/3187 * https://crbug.com/aomedia/3190 * https://crbug.com/aomedia/3195 * https://crbug.com/aomedia/3197 * https://crbug.com/aomedia/3201 * https://crbug.com/aomedia/3202 * https://crbug.com/aomedia/3204 * https://crbug.com/aomedia/3205 * https://crbug.com/aomedia/3207 * https://crbug.com/aomedia/3208 * https://crbug.com/aomedia/3209 * https://crbug.com/aomedia/3213 * https://crbug.com/aomedia/3214 * https://crbug.com/aomedia/3219 * https://crbug.com/aomedia/3222 * https://crbug.com/aomedia/3223 * https://crbug.com/aomedia/3225 * https://crbug.com/aomedia/3226 * https://crbug.com/aomedia/3228 * https://crbug.com/aomedia/3232 * https://crbug.com/aomedia/3236 * https://crbug.com/aomedia/3237 * https://crbug.com/aomedia/3238 * https://crbug.com/aomedia/3240 * https://crbug.com/aomedia/3243 * https://crbug.com/aomedia/3244 * https://crbug.com/aomedia/3246 * https://crbug.com/aomedia/3248 * https://crbug.com/aomedia/3250 * https://crbug.com/aomedia/3251 * https://crbug.com/aomedia/3252 * https://crbug.com/aomedia/3255 * https://crbug.com/aomedia/3257 * https://crbug.com/aomedia/3259 * https://crbug.com/aomedia/3260 * https://crbug.com/aomedia/3267 * https://crbug.com/aomedia/3268 * https://crbug.com/aomedia/3269 * https://crbug.com/aomedia/3276 * https://crbug.com/aomedia/3278 * https://crbug.com/chromium/1290068 * https://crbug.com/chromium/1303237 * https://crbug.com/chromium/1304990 * https://crbug.com/chromium/1321141 * https://crbug.com/chromium/1321388 * https://crbug.com/oss-fuzz/44846 * https://crbug.com/oss-fuzz/44856 * https://crbug.com/oss-fuzz/44862 * https://crbug.com/oss-fuzz/44904 * https://crbug.com/oss-fuzz/45056 Bug: aomedia:3281 -
