I'm builidng and running a few variants of ffmpeg as part of the continuous build. See: http://builds.linaro.org/toolchain/gcc-linaro-4.5+bzr99435/logs/armv7l-maverick-cbuild17-pavo3/ and check out ffmpegbench*run.txt. See the first line of ffmpegbench*configure.txt for the configure options used to build it. The test files are here: http://ex.seabright.co.nz/misc/cbuild/live/cbuild/files/ffmpeg/ And the scripts that tie it together: http://bazaar.launchpad.net/~cbuild/%2Bjunk/cbuild/annotate/head%3A/lib/ffmpegbench-variants.mk http://bazaar.launchpad.net/~cbuild/%2Bjunk/cbuild/annotate/head%3A/lib/ffmpegbench.mk Note that there's the 'plain' -O2, 'asm' with assembler backend, 'size' -Os, and 'neon' -mfpu=neon versions. Note also that ffmpeg turns on '-fno-tree-vectorise' by default. -- Michael _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
