FFMPEG.EXE and all software packages written around it crash on my computers.

[mstrait]

Summary of the bug:
executing mp42avi, mp4cam2avi, ffmpeg, etc. crashes.

How to reproduce:
run any package or just "ffmpeg.exe" from command line

Additional information:

I have been unable to find hardware requirements for ffmpeg.

I'm guessing ffmpeg is just incompatible with my 200MHz Pentium MMX processor in my Gateway Solo 2300 and 166MHz Pentium MMX processor in my IBM340 desktop.

I have no problems on the Pentium III computer at work.

I would greatly appreciate a reply by email

[Ridley Combs]

That's an illegal instruction; it probably indicates that the executable used SSE or some other extension that your CPU doesn't support. This is most likely due to you using a build of ffmpeg meant for newer processors; try building it yourself using -march=native or the equivalent arg for your compiler; reopen this ticket if the issue persists.

Also, note that while as far as I'm aware nobody's officially deprecated support for pre-SSE CPUs and Windows XP, you might have a hard time finding anyone willing to work on fixes for either.

[Carl Eugen Hoyos]

Could you test the following configure line?

$ ./configure --arch=x86 --target-os=mingw32 --cross-prefix=i686-w64-mingw32- --disable-w32threads --disable-pthreads --disable-zlib --disable-bzlib --extra-cflags=-DPTW32_STATIC_LIB

Does it change anything?
