package/f*: fix wrapping of Config.in help text

2017-07-31T17:09:09+00:00

The check-package script when ran gives warnings on text wrapping on all of these Config files. This patch cleans up all warnings related to the text wrapping for the Config files starting with the letter f in the package directory. The appropriate indentation is: <2 spaces><62 chars> See http://nightly.buildroot.org/#writing-rules-config-in for more information. Signed-off-by: Adam Duskett Signed-off-by: Thomas Petazzoni

package/ffmpeg: disable build of nvidia hardware acceleration support

ffmpeg: do not build on m68k coldfire

2017-05-29T21:31:51+00:00

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.

package/f*/Config.in: fix ordering of statements

The check-package script when ran gives warnings on ordering issues on all of these Config files. This patch cleans up all warnings related to the ordering in the Config files for packages starting with the letter f in the package directory. The appropriate ordering is: type, default, depends on, select, help See http://nightly.buildroot.org/#_config_files for more information. Signed-off-by: Adam Duskett Signed-off-by: Thomas Petazzoni

ffmpeg: fix neon support for aarch64

2017-04-14T09:41:24+00:00

ffmpeg ported arm 32-bit NEON code to aarch64 as hard dependency: http://ffmpeg.org/pipermail/ffmpeg-devel/2016-November/202733.html Buildroot option BR2_ARM_CPU_HAS_NEON handles only the 32bit case: https://git.buildroot.net/buildroot/commit/?id=0976cd6cd64a128a2ac921e4f35f0e7cbe306692 For aarch64 we need to make sure to pass --enable-neon in order to prevent a link error, fixes http://autobuild.buildroot.net/results/fa4/fa46003249664b1f97f6c18253c84cd3d6fb9cdb/ Signed-off-by: Bernd Kuhls Signed-off-by: Thomas Petazzoni
