Hiya! With the dvdwizard developer I'm troubleshooting problem of transcode crashing when called in dvdcpics script...
On #transcode I was told about the workaround to use '-V rgb24' and it
really helps, but the man says 'rgb24' is the older internal format
and it should not be used. The other format is 'yuv420p' as default
standard.
By more careful inspection of log file the following is found:
> transcode V: IA32/AMD64 accel | sse3 sse2 sse mmx cmove asm
> decode_mpeg2.c libmpeg2 acceleration: mmxext
> /usr/bin/dvdcpics: line 263: 17694 Segmentation fault ...
transcode wants to use mmxext instruction set while my cpu (i7 860)
does not provide it and I built transcode-1.1.5 with:
./configure --prefix=/usr \
--enable-sse=no --enable-sse2=no --enable-altivec=no --enable-mmx \
--enable-lame --enable-ogg --enable-vorbis --enable-theora \
--enable-libdv --enable-libxml2 --enable-v4l \
--enable-imagemagick --enable-libjpeg --enable-lzo --enable-mjpegtools \
--enable-sdl --enable-freetype2 --enable-a52 --enable-libpostproc \
--enable-xvid --enable-x264 --enable-libmpeg2 --enable-libmpeg2convert \
--enable-ffmpeg --enable-alsa \
--with-imagemagick-prefix=/usr \
--with-lame-libs=/usr \
--with-lzo-libs=/usr/lib \
--with-libavcodec-prefix=/usr \
--with-libavcodec-includes=/usr/include \
--with-libavcodec-libs=/usr/lib || return 1
on my x86_64 archlinux.

Afaics, there is no separate option to enable/disable mmxext set.
I've tried to set --accel C, but it does not help.
Any hint?
Sincerely,
Gour
