I rebased against master to pick up a recent CI fix and all tasks are now passing. |
Available from aom v3.1.0, this usage mode is considered the default setting for still images. It uses a single pass and removes all keyframe logic, resulting in significantly fewer memory allocations and halves CPU time. libavif has already adopted this as the default.

@farindk this is super good enhancement. Tried in production and works like a charm. Can we merge it? |

Great. Thank you. |

Available from aom v3.1.0, the new "all intra" usage mode is now considered its best setting for still images.
From what I can tell, it uses a single pass and skips the keyframe logic (i.e. everything is intra-frame), resulting in significantly fewer memory allocations in addition to almost halving CPU time. The compression ratio is nearly identical, sometimes better, and the worst case I've found so far was 0.8% larger.

libavif has already adopted this as the default - see AOMediaCodec/libavif#539
Homebrew currently provides aom v3.1.0 so the macOS CI job will test this.
