[FFmpeg-user] Compile ffmpeg on mips-qemu

[Martin Vignali]

Hello,

I would like to compile ffmpeg on mips, in order to test the exr decoder on
it.

I try several configure line, but when i launch ffmpeg, i still have
"Illegal instruction"

I use qemu on mac os x, launch with this command :
qemu-system-mips64 -M malta -kernel ./vmlinux-3.2.0-4-5kc-malta -hda
./debian_wheezy_mips_standard.qcow2 -append "root=/dev/sda1 console=tty0"
-redir tcp:2222::22



Configure result :
./configure --arch=mips64 --prefix=../build --disable-ffplay
--disable-ffprobe --disable-ffserver --enable-zlib --disable-asm
--disable-videotoolbox --disable-audiotoolbox --disable-vda
--disable-everything --enable-demuxer=image2 --enable-muxer=framecrc
--disable-decoders --enable-decoder=exr --enable-protocol=file
--enable-protocol=pipe --enable-encoder=rawvideo --disable-doc
--extra-ldflags=-static
