MPlayer interrupted by signal 6 in module: demux_open

  • 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 read the bugreports page http://mplayerhq.hu/DOCS/HTML/en/bugreports.html
compile svn mplayer from source manually
and provide gdb backtrace like the docs say.

9 times out of 10, crashes go away with a manually compiled mplayer.

A.6.6. Crashes

You have to run MPlayer inside gdb and send us the complete output or if you
have a core dump of the crash you can extract useful information from the Core
file. Here's how:
A.6.6.1. How to conserve information about a reproducible crash

Recompile MPlayer with debugging code enabled:

./configure --enable-debug=3
make

and then run MPlayer within gdb using:

gdb ./mplayer

You are now within gdb. Type:

run -v options-to-mplayer filename

and reproduce your crash. As soon as you did it, gdb will return you to the
command line prompt where you have to enter

bt
disass $pc-32 $pc+32
info all-registers

comment:2 Changed 12 years ago by reimar

I think in this case the V4L2 device only supports (MPEG2?) compressed formats
(this line indicates that: "v4l2: get format: unknown (0x4745504d)") as output,
which MPlayer does not support.
If you use some other program to set up the tuner, mplayer /dev/v4l2/video0
might work.
Or actually, looking at the dmesg:
Sun Nov 26 22:43:47 2006: Nov 26 22:43:47 localhost kernel: ivtv0: Registered
device video0 for encoder MPEG
Sun Nov 26 22:43:47 2006: Nov 26 22:43:47 localhost kernel: ivtv0: Registered
device video32 for encoder YUV

Try to make mplayer use /dev/v4l2/video32
