Hi, all
I use emerge mplayer to my media, it can play a video, however, when I use keyboard control (such as 0,9,<,>)to control mplayer crashed.

Here is mplayer crash information
Code:

MPlayer interrupted by signal 4 in module: filter video
- 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.

I wonder if it could be related to on-screen displays. Does "f" for fullscreen or spacebar for pause/play cause it to crash?

Thank you BradN.
"f" for fullscreen or spacebar for pause/play won't cause it to crash.
I can use "f" and "space".
So, what can I do, get gnome-mplayer or smplayer.

It means the problem is probably in on-screen displays. The keys you mentioned all try to display to the screen when you press them, but space and f don't. I would try looking to see if it is using a bad font or something like that, or if you can just shut off the on-screen displays entirely as a workaround.

Here are some options for mplayer to look at (from man mplayer):

Code:
       -font <path to font.desc file, path to font (FreeType), font pattern (Fontconfig)>
              Search  for  the  OSD/SUB  fonts  in  an alternative directory (default for normal fonts: ~/
              .mplayer/font/font.desc, default for FreeType fonts: ~/.mplayer/subfont.ttf).
              NOTE: With FreeType, this option determines the path to the text font file.   With  Fontcon-
              fig, this option determines the Fontconfig font pattern.

              EXAMPLE:
                 -font ~/.mplayer/arial-14/font.desc
                 -font ~/.mplayer/arialuni.ttf
                 -font 'Bitstream Vera Sans'
                 -font 'Bitstream Vera Sans:style=Bold'

       -fontconfig (fontconfig only)
              Enables the usage of fontconfig managed fonts.
              NOTE: By default fontconfig is used for libass-rendered subtitles and not used for OSD. With
              -fontconfig it is used for both libass and OSD, with -nofontconfig it is not used at all.

       -osdlevel <0-3> (MPlayer only)
              Specifies which mode the OSD should start in.
                 0    subtitles only
                 1    volume + seek (default)
                 2    volume + seek + timer + percentage
                 3    volume + seek + timer + percentage + total time


for example, -osdlevel 0 would maybe make it stop crashing for a video with no subtitles, but you wouldn't see any status displays.

Thank you BradN.
I try your method. When I use -osdlevel 0 to play some videos Mplayer do not crash. But When I use -osdlevel 1 and -font /usr/share/fonts/corefonts/arial.ttf It crash again. I try some font such as msyh.tff, arial.tff, arialuni.ttf. However, It crash again. When I use -osdlevel 2 and 3 Mplayer can not play any movie.

Try running mplayer with -vo gl, that uses a different method to render the OSD than default Xv so it might not crash.

Unfortunately I don't know what exactly would be causing it to crash, I would suggest recompiling/upgrading any font related packages, but that's just guessing. Maybe try turning on/off font related use flags. My mplayer has "truetype" use flag on.

If it is something related to a missing file, maybe running mplayer with strace could give a hint:
emerge strace
strace -f mplayer

Just some ideas to try, I don't know if it will help :(

Also try Ant P.'s suggestion, worth a shot.

I used smplayer at first, but I eventually lost patience with bugs
in qt updates crashing it. I much prefer running mplayer in text mode,
which has given me no problems. But the only keyboard controls
I ever use are p (pause), m (mute), * (increase volume), and q (quit).
I only use it for playing audio.

"Illegal instruction" is a fairly rare error. You could try disabling the
USE flags for various instruction set subsets that would most likely
be used at assembler level (3DNow, mmx, sse, sse2, etc), re-emergeing
mplayer, and see if it still crashes. Or disable all of them and add
them back one at a time and test. (I am assuming that gcc is less
likely to generate machine code with -march=native on a fairly widely
used cpu that raises that error than that hand-coded assembler that
uses one of those instruction set subsets might raise that error.)

Since when does an Intel Core cpu have support for 3DNow instructions?
Maybe it does and I simply do not know about it, but 3DNow was an AMD
extension to the x86 instruction set, so that USE flag is the first one I would
suspect on your system, assuming that I am reading your emerge --info
output correctly.

Oh, didn't see that. USE="3dnow -cpudetection" is almost certain to be the root of the problem.

Thank you cwg, I solved the problem by disabling "3dnow" use flag, then mplayer work, all keyboard control work.

Hi,

I have the same issue, and running mplayer with osdlevel=0 fixes it, but activating the osd directly fails.
It used to run without any issues, and then stopped after some upgrade of ffmpeg...

Here is my make.conf:
Code:

CFLAGS="-march=amdfam10 -mtune=generic -mmmx -msse -msse2 -msse3 -mssse3 -msse4a -mabm -O2 -pipe"
CXXFLAGS="${CFLAGS}"

FEATURES="-sandbox"

source /var/lib/layman/make.conf


As you can see I disable the USE flags for mmx sse sse2 mmx2 but that does not change anything (actually no packages were re-emerged) and rebuilt mplayer!

Here is the error message:
Code:
MPlayer interrupted by signal 6 in module: flip_page
- 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.


Please note I am running the mplayer from git git://gitorious.org/vaapi/mplayer.git for vaapi support (running with AMD APU)

Any help would be appreciated!

Thanks

Nevermind, don't mind me, after writing the post I realized that changing my make.conf has no repercussion on me manually building from git!
I am now recompiling with disabled mmx[2-ext] sse[2-3], I'll ask for more help tomorrow if that does not fix the issue...

What does USE flag "mmx2" enable? (I have never heard of it.)
Flags in /proc/cpuinfo do not always match the names of USE
flags. "pni" support in the cpu actually means "sse3" support,
for example, and while there is no pni USE flag there is an
sse3 USE flag. So the "mmx2" USE flag may signal emerge to
enable "mmxext" or something like that.

The reason that those USE flags were of particular interest for
the OP's problem was because of the "Illegal Instruction" error
reported. Those USE flags often have the effect of enabling
hand-coded assembler in the code, where I guessed that one
might more likely find code that caused that error on a common
cpu than that "gcc -march=native" would generate code for
that same cpu that would cause the cpu to report an "illegal
instruction" error.

That would not necessarily be the only reason that the "on-screen
display" (OSD) in mplayer might crash, though.

Did your error logs show anything like that?

(A lot of people change their optimization flags from -O2 to
-O1 or -O0 when compiling with -ggdb for debugging. That
seems clueless to me. When debugging with gdb, I want it
to trace the code that I am actually running when the error
happens, with the addition of the code annotations enabled
by -ggdb. So I leave the -O flag at -O2 if that is what I used
for the program that showed the error. gdb still works with
"-O2 -ggdb" code.)

Thanks wcg,

I get the point, obviously these flags did not fix the problem...
I'll try to look at it this week using gdb to see what it gives me!
