The libav version built into the gst-ffmpeg code produces a bogus
binary on SPARC, which causes the following error of the
check-bin-arch script:
ERROR: architecture for ./usr/lib/gstreamer-0.10/libgstffmpeg.so is Sparc v8+, should be Sparc
ERROR: architecture for ./usr/lib/gstreamer-0.10/libgstpostproc.so is Sparc v8+, should be Sparc
ERROR: architecture for ./usr/lib/gstreamer-0.10/libgstffmpegscale.so is Sparc v8+, should be Sparc
The problem is the following bit of code in
gst-lib/ext/libav/configure:
elif enabled sparc; then
enabled vis && check_asm vis '"pdist %f0, %f0, %f0"' -mcpu=ultrasparc &&
add_cflags -mcpu=ultrasparc -mtune=ultrasparc
I.e, it checks if the architecture supports the pdist
instruction... but forces -mcpu to ultrasparc while doing so. So it's
like "let's see if this Ultrasparc instruction exists when I force the
compiler to think I'm using Ultrasparc", which is non-sensical. This
has been fixed later on in libav upstream:
https://git.libav.org/?p=libav.git;a=commit;h=6aa93689abe8c095cec9fa828c2dee3131008995
However, this commit cannot be backported as-is since the shell
function check_inline_asm did not exist in the old libav version
bundled in gst-ffmpeg.
Therefore, we take the simpler route of disabling the VIS
optimizations on SPARCv8 and Leon3.
