avif conversion utility segfaults

[MartiCode]

Using command: avif -s 5 -q 25 -e IMG_3890.JPG -o delme.avif

Gives: fatal error: unexpected signal during runtime execution [signal SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0x7f28b05b14f4]

Thank you for the report.

Is it happening on any image or only this particular? What libaom version do you use?

[MartiCode]

Seems to happen with every JPEG I tried. The version of libaom-dev as reported by apt:

Version: 1.0.0-3~18.04.york0 Depends: libaom0 (= 1.0.0-3~18.04.york0)

[Kagami]

I've installed the same libaom in Ubuntu 18.04 in Docker container and can't reproduce that issue. It might be related to your system.

Try with latest libaom from git. See instructions here.

I have the same issue and I installed it to WSL on Windows 10.

@Kagami can you paste your docker file?

[Kagami]

FROM ubuntu:18.04

RUN apt-get update \
  && apt-get install -y software-properties-common git golang \
  && add-apt-repository -y ppa:jonathonf/ffmpeg-4 \
  && apt-get update \
  && apt-get install -y libaom-dev \
  && mkdir -p /go/src/github.com/Kagami \
  && cd /go/src/github.com/Kagami \
  && git clone https://github.com/Kagami/go-avif.git \
  && GOPATH=/go go get -v ./...

ENTRYPOINT ["/go/bin/avif"]

docker build -t avif .
docker run --rm -v `pwd`:/mnt avif -e /mnt/tiger.jpg -o /mnt/tiger.avif

This works fine for me.

[MartiCode]

It seems to work with smallish images and not with larger ones. Could it be an issue with running out of memory? I have tried to manually convert to AVIF using ffmpeg/libaom/mp4box and on larger pictures (ie 4000x5000) the process quickly balloons and runs out of memory (on a 32Gb system). If so some check and proper "out of memory" error reporting would be useful.

[Kagami]

Thanks, I finally can reproduce issue!

On 5412x7216 image with libaom 1.0.0 I get segfault and with latest libaom from git it's:

$ aomenc -o big.ivf big.y4m
Failed to initialize encoder: Memory allocation error

I will report that to aomedia.

[Orum]

Any update on this? Is libaom still bugged? If so, I don't suppose you're willing to support another encoder in the meantime...
