m68k coldfire causes ffmpeg to think atomic intrinsics are available, so ffmpeg doesn't use its fallback on pthreads based atomic operations. However, m68k coldfire doesn't provide properly working sync 4 atomics, causing a build failure. Since fixing ffmpeg on m68k coldfire is not really important (who wants to use ffmpeg on such platform?), we simply disallow the selection of ffmpeg on this platform. Alternate approaches have been proposed in the past: - Bernd Kuhls proposed in http://patchwork.ozlabs.org/patch/766909/ to add a dependency on BR2_TOOLCHAIN_HAS_SYNC_4, but this is wrong because other architectures that lack sync 4 atomics, such as Sparc, can build ffmpeg perfectly fine thanks to the pthreads based fallback code. - Waldemar Brodkorb proposed in https://patchwork.ozlabs.org/patch/756664/ to add an explicit option in ffmpeg configure to force the use of pthreads based atomics. However, we believe that running ffmpeg on m68k coldfire is such an unlikely use case that it isn't worth carrying a patch for this.
