Package: ffmpeg Version: 0.cvs20070307-6 Severity: normal Tags: patch For arm, ffmpeg does not currently contain code to detect the processor and switch on processor-specific optimisations, like it can do on x86. Instead, the optimisations it enables are determined at compile time.
I recently tried running the armel build of ffmpeg on a machine, and it failed with "Illegal instruction". It turns out this was because the package chose to compile in support for the armv6 processor, which is still fairly rare (at least, I don't have any :-). Debian continues to target older arm processors, so this is not appropriate. I haven't checked if it did a compile-time test for armv6, or if the version in unstable just always enables armv6 code. If the former, then this probably doesn't yet break the arm binaries in debian, since all our arm buildds are quite old netwinders. The buildds for the armel port are much more recent and faster machines, so it might only be breaking there currently. Anyway, please apply the attached patch, which turns these optimisations off at configure time. -- System Information: Debian Release: lenny/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: i386 (i686) Kernel: Linux 2.6.22-1-686 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages ffmpeg depends on: ii libavcodec1d 0.cvs20070307-6 ffmpeg codec library ii libavformat1d 0.cvs20070307-6 ffmpeg file format library ii libavutil1d 0.cvs20070307-6 ffmpeg utility library ii libc6 2.6.1-1 GNU C Library: Shared libraries ii libfreetype6 2.3.5-1+b1 FreeType 2 font engine, shared lib ii libimlib2 1.3.0.0debian1-4 powerful image loading and renderi ii libsdl1.2debian 1.2.11-9 Simple DirectMedia Layer ii libswscale1d 0.cvs20070307-6 ffmpeg video scaling library ffmpeg recommends no packages. -- no debconf information -- see shy jo
