 |
|
Hi there!
!!!PLEASE DONT BE SCARED OF THE HUGE POST, MOST OF THE OUTPUT IS JUNK WHICH SHOULDNT BE VERY INTERESTING!!!
I have a strange problem with mplayer (1.0_pre8-r1): whenever i try to seek in a video (no matter what codec it has) mplayer crashes. The normal output is this
| Code: | $ mplayer avatar\ -\ trailer.wmv

MPlayer interrupted by signal 4 in module: decode_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.

my useflags are for mplayer:

The seek in mp3-files works. I already tried recompiling it without custom cflags set, no change. the gdb backtrace gives me this:

This is already the output of a mplayerversion compiled with USE="debug"...
Are there any suggestions? I have a pentium4 and had prior to it an athlonxp, though i reemerged world after the change.
thx in advance

| For starters, try recompiling it with "mmxext" and "rtc" USE flags added. And you might also post your CFLAGS setting, the "illegal instruction" seems to have something to do with the mmx and sse instruction sets. |

Thank you, that helped! If there is further interest in this problem i can post more output/backtraces/whatever u want.
With kind regards

I think that is not needed, since obviously mplayer just got confused about your cpu and its instruction sets by using the wrong compile options. Also since you have turned the "rtc" USE flag on, you might want to execute the following as root:
| Code: |
echo 1024 >/proc/sys/dev/rtc/max-user-freq
echo "dev.rtc.max-user-freq = 1024" >>/etc/sysctl.conf
|
That way your hardware real-time clock will be used instead of software sleep, decreasing the load on your CPU while using mplayer. Also make sure normal users can read from /dev/rtc:

With kind regards
