Running: jpeg2yuv -n 50 -I p -f 29.97 -j background.jpg causes an immediate segfault. I am using a jpeg file that use to work fine with the above command. I am using mjpegtools 1.8.0. I thought the newer version was causing the problem so I backed off to 1.6.2-r4 and have the same problem. This was working a couple months ago. 1.8.0 isn't the problem since I regressed to the stable version and had the exact same problem. I ran: emerge -ev mjpegtools thinking a dependent package was causing the problem. Rebooted, and tried again. I tried several other jpeg files that I have successfully encoded before and I always immediately get a segfault. I have a feeling it is something on my end, but a day of searching and trial and error has come up emptly. A jpeg file that causes a segfault is located here: http://webpages.charter.net/kgroombr/background.jpg Reproducible: Always Steps to Reproduce: 1. Run: jpeg2yuv -n 50 -I p -f 29.97 -j background.jpg Actual Results: segfault Expected Results: Output redirected to mpeg2enc to create screen for a dvd I am converting the jpeg files to png and using the png2yuv and all is working fine. emerge --info Portage 2.0.53_rc5 (default-linux/x86/2005.0, gcc-3.4.4, glibc-2.3.5-r2, 2.6.13-ck7 i686) ================================================================= System uname: 2.6.13-ck7 i686 Unknown CPU Typ Gentoo Base System version 1.12.0_pre8 dev-lang/python: 2.4.2 sys-apps/sandbox: 1.2.13 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.20 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -pipe -march=athlon-xp -fomit-frame-pointer -mmmx -msse -m3dnow -mfpmath=sse" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -pipe -march=athlon-xp -fomit-frame-pointer -mmmx -msse -m3dnow -mfpmath=sse" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://mirror.datapipe.net/gentoo http://gentoo.chem.wisc.edu/gentoo/ http://gentoo.osuosl.org/ http://mirror.phy.olemiss.edu/mirror/gentoo http://gentoo.mirrors.easynews.com/linux/gentoo/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 3dnow 3dnowext S3TC X a52 aac acpi acpi4linux alsa apache2 apm arts avi berkdb bitmap-fonts bzip2 cddb cdr crypt cups curl dga divx4linux dvd dvdr dvdread eds emboss emoticon encode faad fam ffmpeg flac foomaticdb fortran freetype gdbm gif gimp gpm gstreamer gtk2 ieee1394 imagemagick imlib ipv6 joystick jpeg kde libg++ libwww live mad mikmod mjpeg mmx mmxext motif mozsvg mp3 mpeg mpeg4 mplayer nas ncurses network nls nomalloccheck nptl nptlonly nvidia ogg oggvorbis openal opengl opens pam pdflib perl png python qt quicktime readline scanner sdl slang snmp spell sse ssl svg svga tcltk tcpd tiff transcode truetype truetype-fonts type1 type1-fonts unicode usb v4l2 vorbis win32codecs wmf xine xml2 xmms xpm xv xvid zlib zvbi userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS
I have tried the command jpeg2yuv -n 50 -I p -f 29.97 -j background.jpg > background.yuv4mpeg on your image and it does work for me. I have mjpegtools-1.8.0 on amd64.
I have the same problem executing the same command on the same file. Moreover I am having systematic segfaults with several other commands involving ffmpeg or mpeg2enc on movies in dv format. e.g. transcode -x dv,dv -i fred-001.dv -y ffmpeg -F 8 -o fred-001-video -m fred-001-audio -N 0x2000 -E 48000 -w 7500 -b 256 --export_prof dvd-pal --export_asr 2 --encode_fields b or (generated by qDvdauthor): jpeg2yuv -n 50 -I p -f 25 -j "+BACKGROUND_FULL_NAME+" | mpeg2enc -n p -f 8 -o "+TEMP_PATH+/+MENU_NAME+/menu.m2v" I had these segfaults just after an emerge -u world, four days ago.

is it possible to change the severity of this bug? It renders mythburn useless, and I can't find any way to work around it.
jpeg version? could you please use genlop to discover what did you emerged that cause that issue (glibc maybe?!) I can't reproduce the issue on my x86 system and I don't have it on my ppc system but I could test once I build it.

I don't know what you mean by jpeg version other then this: media-libs/jpeg-6b-r6 it never worked for me so genlop won't work
Hey, I changed my cflags to be just -pipe and I removed all my use flags I re-emerged jpeg-mmx and now it seems to work can someone try it? I have been doing all sorts of thing to try and fix this that it could be a combo of things. But I think this is what triggered the fix. I also, emerge =media-libs/jpeg-6b-r5 not -r6 which I had before. HTH
You are on to something. I just temporarily changed my use flags, emerged jpeg-mmx, and now it works. Great job! Sounds like it is an issue with our processors. I have an Athlon XP Barton core. Ken
Sounds like you guys figured this out. Good job. Technically INVALID since it was hardware.
