--- Begin Message ---Package: ffmpeg Version: 7:3.3.3-1 Severity: important Tags: patch User: ubuntu-de...@lists.ubuntu.com Usertags: origin-ubuntu artful ubuntu-patch autopkgtest Dear maintainers, The latest release of ffmpeg enables NEON support by default when building on armhf; however, NEON support is not a standard part of the ARMv7 ABI, and Debian supports running armhf on chips that do not implement NEON. Using NEON based on runtime detection of support for it is fine, but the existing ffmpeg implementation doesn't appear to do this, instead using NEON based on build-time configuration with no fallback. This issue was noticed in Ubuntu only because the autopkgtests for ffmpeg and x264 triggered an unaligned access in the NEON code, which is *also* not a portable assumption on armhf; however, if the NEON code had not had any unaligned access, the fact that NEON was used would have gone unnoticed on Ubuntu infrastructure. http://autopkgtest.ubuntu.com/packages/f/ffmpeg/artful/armhf http://autopkgtest.ubuntu.com/packages/x/x264/artful/armhf (And if upstream does fix their code to support runtime detection of NEON support, then there will be a different bug for us to worry about fixing!)
