Bug Description

#974125 mplayer crashes with illegal instruction is said to be about lack of sse3

I am testing Lubuntu 12.04 daily build mainly to make sure it works with a non-pae cpu: IBM thinkpad T41.

This bug in mplayer is independent of pae and sse3 as far as I can see. Mplayer fails to play and prints 'illegal instruction, bad usage of cpu/fpu/ram'. I tested it also in a Dell Dimension 4600 with Pentium 4 2.8 GHz with pae, and it was the same problem, so the mplayer bug is not related to non-pae. I saw the report that the bug should be related to sse3. But I don't think so, because an AMD Athlon cpu without sse3 can play video with mplayer (booted from our non-pae CD drive). Another computer with double Xeon cpus also plays well with mplayer. So my experience is that it works with 64-bit computers but won't work with 32-bit computers. I have tested the i386 iso file burned to a CD booting the various computers.

MPlayer interrupted by signal 4 in module: read_subtitles_file
- MPlayer crashed by an 'Illegal Instruction'.
  It usually happens when you run it on a CPU different than the one it was
  compiled/optimized for.
  Verify this!
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible bug.
Unfortunately I am not very good at compiling programs

How can I find bug #928793? I have tried to seach for it with the search tool, but in vain. Is it public or hidden? Maybe you can copy a relevant (and publishable) description of that bug, so that I can test if it is really the same one.

Changed in mplayer2 (Ubuntu):
status: New → Confirmed

Same here, running 32 bit 12.04 on an i5 processor.

Mplayer immediately crashes upon launch, however it works fine on a 64 bit system.

Also, I cannot find the alleged bug that this is supposed to be a duplicate of.

Hi ! Just installed Lubuntu on an eeePC701 (Celeron), and I have the same issue.

Any news on this topic ?

Thanks !
