Since these commits http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=adf8227cf4e7b4fccb2ad88e1e09b6dc00dd00ed http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=db7f1c7c5a1d37e7f4da64a79a97bea1c4b6e9f8 compilation on arm4/arm5 fails: libavcodec/libavcodec.so: undefined reference to `ff_startcode_find_candidate_armv6' Because libavcodec/arm/Makefile contains ARMV6-OBJS-$(CONFIG_STARTCODE) += arm/startcode_armv6.o function ff_startcode_find_candidate_armv6 is not included for older ARM archs. The bug was found during automatic buildroot builds: http://autobuild.buildroot.net/results/ec7/ec71e4f16ee9106747dff5f15999cbd17903e76f//build-end.log Quote from configure summary: ARCH arm (armv4t) big-endian no runtime cpu detection yes ARMv5TE enabled no ARMv6 enabled no ARMv6T2 enabled no http://autobuild.buildroot.net/results/be7/be72eb182eaccf0064a32c9dfc2ac1c0d6555506/build-end.log ARCH arm (armv5te) big-endian no runtime cpu detection yes ARMv5TE enabled yes ARMv6 enabled no ARMv6T2 enabled no This patch provides the necessary #if clauses as discussed with Michael: https://ffmpeg.org/pipermail/ffmpeg-devel/2014-September/163329.html Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
