It adds support for run-time CPU feature detection for Arm + platforms, as well as support for darwin23 (macOS 14). + + - Upgrading: + This release is ABI incompatible with the previous release. + + Various new features for rate control library for real-time: SVC parallel + encoding, loopfilter level, support for frame dropping, and screen content. + + New callback function send_tpl_gop_stats for vp9 external rate control + library, which can be used to transmit TPL stats for a group of pictures. A + public header vpx_tpl.h is added for the definition of TPL stats used in + this callback. + + libwebm is upgraded to libwebm-1.0.0.29-9-g1930e3c. + + - Enhancement: + Improvements on Neon optimizations: VoD: 12-35% speed up for bitdepth 8, + 68%-151% speed up for high bitdepth. + + Improvements on AVX2 and SSE optimizations. + Improvements on LSX optimizations for LoongArch. + 42-49% speedup on speed 0 VoD encoding. + Android API level predicates. + + - Bug fixes: + Fix to missing prototypes from the rtcd header. + Fix to segfault when total size is enlarged but width is smaller. + Fix to the build for arm64ec using MSVC. + Fix to copy BLOCK_8X8's mi to PICK_MODE_CONTEXT::mic. + Fix to -Wshadow warnings. + Fix to heap overflow in vpx_get4x4sse_cs_neon. + Fix to buffer overrun in highbd Neon subpel variance filters. + Added bitexact encode test script. + Fix to -Wl,-z,defs with Clang's sanitizers. + Fix to decoder stability after error & continued decoding. + Fix to mismatch of VP9 encode with NEON intrinsics with C only version. + Fix to Arm64 MSVC compile vpx_highbd_fdct4x4_neon. + Fix to fragments count before use. + Fix to a case where target bandwidth is 0 for SVC. + Fix mask in vp9_quantize_avx2,highbd_get_max_lane_eob. + Fix to int overflow in vp9_calc_pframe_target_size_one_pass_cbr. + Fix to integer overflow in vp8,ratectrl.c. + Fix to integer overflow in vp9 svc. + Fix to avg_frame_bandwidth overflow. + Fix to per frame qp for temporal layers. + Fix to unsigned integer overflow in sse computation. + Fix to uninitialized mesh feature for BEST mode. + Fix to overflow in highbd temporal_filter. + Fix to unaligned loads w/w==4 in vpx_convolve_copy_neon. + Skip arm64_neon.h workaround w/VS >= 2019. + Fix to c vs avx mismatch of diamond_search_sad(). + Fix to c vs intrinsic mismatch of vpx_hadamard_32x32() function. + Fix to a bug in vpx_hadamard_32x32_neon(). + Fix to Clang -Wunreachable-code-aggressive warnings. + Fix to a bug in vpx_highbd_hadamard_32x32_neon(). + Fix to -Wunreachable-code in mfqe_partition. + Force mode search on 64x64 if no mode is selected. + Fix to ubsan failure caused by left shift of negative. + Fix to integer overflow in calc_pframe_target_size. + Fix to float-cast-overflow in vp8_change_config(). + Fix to a null ptr before use. + Conditionally skip using inter frames in speed features. + Remove invalid reference frames. + Disable intra mode search speed features conditionally. + Set nonrd keyframe under dynamic change of deadline for rtc. + Fix to scaled reference offsets. + Set skip_recode=0 in nonrd_pick_sb_modes. + Fix to an edge case when downsizing to one. + Fix to a bug in frame scaling. + Fix to pred buffer stride. + Fix to a bug in simple motion search. + Update frame size in actual encoding. + 2023-09-29 v1.13.1 "Ugly Duckling" This release contains two security related fixes. One each for VP8 and VP9. |
