This release includes compression efficiency improvement, speed improvement
for realtime mode, as well as some new APIs.
- Upgrading:
Support for PSNR calculation based on stream bit-depth.
New encoder control IDs added:
- AV1E_SET_ENABLE_RECT_TX
- AV1E_SET_VBR_CORPUS_COMPLEXITY_LAP
- AV1E_GET_BASELINE_GF_INTERVAL
- AV1E_SET_ENABLE_DNL_DENOISING
New decoder control IDs added:
- AOMD_GET_FWD_KF_PRESENT
- AOMD_GET_FRAME_FLAGS
- AOMD_GET_ALTREF_PRESENT
- AOMD_GET_TILE_INFO
- AOMD_GET_SCREEN_CONTENT_TOOLS_INFO
- AOMD_GET_STILL_PICTURE

- AOMD_GET_S_FRAME_INFO
New aom_tune_content enum value: AOM_CONTENT_FILM
New aom_tune_metric enum value: AOM_TUNE_VMAF_NEG_MAX_GAIN
Coefficient and mode update can be turned off via
AV1E_SET_{COEFF/MODE}_COST_UPD_FREQ.
New key & value API added, available with aom_codec_set_option() function.
Scaling API expanded to include 1/4, 3/4 and 1/8.
- Enhancements:
Better multithreading performance with realtime mode.
New speed 9 setting for faster realtime encoding.
Smaller binary size with low bitdepth and realtime only build.
Temporal denoiser and its optimizations on x86 and Neon.
Optimizations for scaling.
Faster encoding with speed settings 2 to 6 for good encoding mode.
Improved documentation throughout the library, with function level
documentation, tree view and support for the dot tool.
