SUSE-SU-2024:4333-1

Description of the patch:

This update for libaom, libyuv fixes the following issues:

libaom was updated to version 3.7.1:

• Bug Fixes:

  • aomedia:3349: heap overflow when increasing resolution
  • aomedia:3478: GCC 12.2.0 emits a -Wstringop-overflow warning on aom/av1/encoder/motion_search_facade.c
  • aomedia:3489: Detect encoder and image high bit depth mismatch
  • aomedia:3491: heap-buffer-overflow on frame size change
  • b/303023614: Segfault at encoding time for high bit depth images

• New upstream release 3.7.0

  • New Features

    • New codec controls:

      • AV1E_SET_QUANTIZER_ONE_PASS: Set quantizer for each frame.
      • AV1E_ENABLE_RATE_GUIDE_DELTAQ: enable the rate distribution guided delta quantization in all intra mode. The 'enable-rate-guide-deltaq' option is added for this control.
      • AV1E_SET_RATE_DISTRIBUTION_INFO: set the input file for rate distribution used in all intra mode. The 'rate-distribution-info' option is added for this control.
      • AV1E_GET_LUMA_CDEF_STRENGTH
      • AV1E_SET_BITRATE_ONE_PASS_CBR

    • AOM_SCALING_MODE is extended to include 2/3 and 1/3 scaling.

    • aom_tune_metric is extended to include AOM_TUNE_VMAF_SALIENCY_MAP. The 'tune' option is extended to include 'vmaf_saliency_map'.

    • SVC example encoder svc_encoder_rtc is able to use the rate control library.

    • Loopfilter level and CDEF filter level is supported by RTC rate control library.

    • New speed (--cpu-used) 11, intended for RTC screen sharing, added for faster encoding with ~3% bdrate loss with 16% IC (instruction count) speedup compared to speed 10.

  • Compression Efficiency Improvements

    • Improved VoD encoding performance

      • 0.1-0.6% BDrate gains for encoding speeds 2 to 6
      • Rate control accuracy improvement in VBR mode

    • RTC encoding improvements

      • Screen content mode: 10-19% BDrate gains for speeds 6 -...
