gst-ffmpeg: work-around bogus configure logic on SPARC 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.
