 Posted: Sat Nov 05, 2011 10:57 pm Post subject: ffmpeg failing to build on ARM |
 |
|
I'm having trouble building ffmpeg on a Cortex-A8 host. Specifically, I get "selected processor does not support 'vpush {d8-d15}'" and other similar errors when building the dsputil_vfp.S file. Since I have -mcpu=cortex-a8 and -mfpu=neon in make.conf, I think my processor definitely supports vpush, that is a NEON instruction. I tried -mfpu=vfp and vfpv3 just in case, nothing seems to work.
Anyone have similar problems, or know how to fix this? |

| Well, I found one way - disable VFP and NEON (./configure --disable-armvfp --disable-neon). That's lame, but I really can't figure out how to get ffmpeg to compile with either. After looking here: https://roundup.libav.org/issue1141 I think the config system used by the library might be a little busted on ARM. |

hi, i'm having the same issue with ffmpeg-0.7.8 on an arm machine.

i tried EXTRA_ECONF="--disable-armvfp --disable-neon" but that didn't work either....
any ideas? |

You can try adding EXTRA_FFMPEG_CONF="--extra-cflags=-mfpu=neon" line to your /etc/make.conf or consider using libav-9999, see https://bugs.gentoo.org/show_bug.cgi?id=349814#c22
edit: Actually it would be EXTRA_FFMPEG_CONF="--extra-cflags=-mfpu=vfpv3-d16" for tegra2. In any case, ffmpeg uses ad-hoc build scripts and just ignores your CFLAGS. |
