Description (last modified by mf2k (Frank Schima))
I've installed Lion a couple of days ago, then port-uninstalled everything, port-cleaned everything (with --all option), then port-selfupdated and reinstalled the stuff I need. Now every time I try to use "scale" filter, mencoder gives me "Segmentation fault". Mplayer, by the way, works fine. Mencodering without scaling works fine. I've tried different sources, got the same result.
Here is what happens when I run mencoder (with debug variant enabled) in GDB:

I have the same issue. I found it goes away when compiling x264 without the +asm variant.

Please provide a crash report. Your gdb log doesn't provide much information. If you're going to do this in gdb, please provide a backtrace of the crashed thread and the output of 'info files' so I can see what library the crashing frame is in. My guess from the previous comment is that it's in libx264.dylib, but that does not match up with the backtrace sine libx264.dylib doesn't seem to have a yuv2yuvX_MMX2 symbol on my system.

So far, 2 people have complained that they have this issue, but neither has posted a crash log. There's nothing I can do without a crash log.

Does this occur with mplayer 1.1? What about the current mplayer-devel (updated today)?

Sorry for the delay. I am on OS X 10.8 now, and the crash still occurs both with mplayer 1.1 and mplayer-devel. Let me know what else you need to be able to fix this.
$ port installed mplayer The following ports are currently installed:
MPlayer @1.1_1+mencoder_extras+x264 (active)
and later: $ port installed mplayer-devel The following ports are currently installed:
mplayer-devel @35203_0+mencoder_extras+x264 (active)
$ port installed x264 The following ports are currently installed:
x264 @20111210_0 x264 @20111210_0+asm (active)

Can you provide a sample video file that triggers this issue?
comment:13 Changed 12 years ago by macports@…
It is triggered with any video file. I tried all avi samples on http://istec.colostate.edu/me/facil/dynamics/avis.htm and mencoder crashes on all of them.

My x264 port wasn't built with +asm, try x264 with -asm

From the Portfile:
# # intel assembler optimizations using yasm continue # to exhibit problems in some cases (see #19835) # disable by default but can be enabled using +asm variant for the adventurous #
