Unable to compile MPlayer on QNX

GENERAL Help

Hmm, I think I found a bug.

When I run it on my Intel Core Duo processor, works fine. When I run it on my Pentium IV, it crashes, complaining that “You may be trying to run Mplayer on a different CPU than it was compiled on”.

23

Yes CoreDuo have some extra instructions and not to mention dual core.

Probably not a bug, There must be an option in the build to force generic X86, at the cost of performance.

24

This really not is the mistake. This mplayer on my side was compiled on CPU Intel(R) Core™2 Quad CPU Q6600 and acts on Core Duo. You should recompile him on older CPU.
To compile I use gcc4.4.0 and command option -march=native -mtune=native to maximization of performance.

MPlayer interrupted by signal 4 in module: af_preinit

  • 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 would like to know how to use the mplayer

    Thanks!!!

OK. I compiling mplayer with -O3 -mtune=generic and send to ajam.org.pl/
It`s Mplayer-generic.tar.bz2. try it.

Thanks bbceler

Anyway to get it to stop trying to play full screen? It freezes my computer.

Possible reasons, problems, workarounds:

  • Most common: broken/buggy audio driver
    • Try -ao sdl or use the OSS emulation of ALSA.
    • Experiment with different values for -autosync, 30 is a good start.
  • Slow video output
    • Try a different -vo driver (-vo help for a list) or try -framedrop!
  • Slow CPU
    • Don’t try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
      e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
  • Broken file
    • Try various combinations of -nobps -ni -forceidx -mc 0.
  • Slow media (NFS/SMB mounts, DVD, VCD etc)
    • Try -cache 8192.
  • Are you using -cache to play a non-interleaved AVI file?
    • Try -nocache.
      Read DOCS/HTML/en/video.html for tuning/speedup tips.
      If none of this helps you, read DOCS/HTML/en/bugreports.html.

Marschen,

What video driver are you using in Photon?

If it’s the plain vanilla VESA driver then I’m not surprised you are using the entire CPU.

I’d imagine MPlayer is only going to work if you happen to have a video card that QNX supports with an actual driver.

Hi Tim

My graphics card is integrated graphics, video driver i830

/usr/photon/bin/io-graphics -di830 vid=0x8086,did=0x2562,pci=0,photon=/dev/photon,xres=1024,yres=768,bitpp=32 -pphoton

Mine is an Nvidia TNT.

Anything new?
