Bug#1022870: libsvtav1enc1: Fails to allocate memory on 32-bit arm architectures
Package: libsvtav1enc1
Version: 1.2.1+dfsg-1
Severity: normal
Dear Maintainer,
I uploaded my package libmedia-convert-perl, with an autopkgtest. As
part of the autopkgtest, it calls ffmpeg to encode a very short media
file to av1 using the svt-av1 encoder.
This works fine on my own laptop (amd64), but it fails when run on the
armhf and armel workers for ci.debian.net. At this point, more
architectures are pending, so more failures may occur later.
Relevant logs:
https://ci.debian.net/data/autopkgtest/testing/armhf/libm/libmedia-convert-perl/27553000/log.gz
https://ci.debian.net/data/autopkgtest/testing/armel/libm/libmedia-convert-perl/27552345/log.gz
It shows the following output:
Running: 'ffmpeg' '-loglevel' 'warning' '-y' '-i' 't/testvids/bbb.mp4' '-threads' '1' '-c:v' 'libsvtav1' '-b:v' '1116.207k' '-minrate' '558.1035k' '-maxrate' '1618.50015k' '-r:v' '24/1' '-crf' '25' '-speed' '4' '-c:a' 'libvorbis' '-b:a' '133431' '-ar' '44100' '-t' '0.1' '-pix_fmt' 'yuv420p' './1sec.webm'

[libvorbis @ 0x13053a0] 41 frames left in the queue on closing

is very similar)
The debian-ci maintainers tell me that the armel worker has 32G of
memory available, which is more than most 64-bit architectures (and in
fact, also more than my own laptop has, on which it works perfectly),
leading me to suspect it is rather a bug in svt-av1 rather than a memory
issue.
Thanks,
