You may need to include log, configuration or sample files in your bug report.
If some of them are quite big then it is better to upload them to our
FTP server in a
compressed format (gzip and bzip2 preferred) and include only the path and file
name in your bug report. Our mailing lists have a message size limit of 80k, if
you have something bigger you have to compress or upload it.
A.6.1. System Information
Your Linux distribution or operating system and version e.g.:
Red Hat 7.1Slackware 7.0 + devel packs from 7.1 ...
kernel version:
uname -a
libc version:
ls -l /lib/libc[.-]*
gcc and ld versions:
gcc -v
ld -v
binutils version:
as --version
If you have problems with fullscreen mode:
Window manager type and version
If you have problems with XVIDIX:
X colour depth:
xdpyinfo | grep "depth of root"
If only the GUI is buggy:
GTK versionGLIB versionGUI situation in which the bug occurs
A.6.2. Hardware and drivers
CPU info (this works on Linux only):
cat /proc/cpuinfo
Video card manufacturer and model, e.g.:
ASUS V3800U chip: nVidia TNT2 Ultra pro 32MB SDRAMMatrox G400 DH 32MB SGRAM
Video driver type & version, e.g.:
X built-in drivernVidia 0.9.623Utah-GLX CVS 2001-02-17DRI from X 4.0.3
Sound card type & driver, e.g.:
Creative SBLive! Gold with OSS driver from oss.creative.comCreative SB16 with kernel OSS driversGUS PnP with ALSA OSS emulation
If in doubt include lspci -vv output on Linux systems.
A.6.3. Configure problems
If you get errors while running ./configure, or autodetection
of something fails, read configure.log. You may find the
answer there, for example multiple versions of the same library mixed on your
system, or you forgot to install the development package (those with the -dev
suffix). If you think there is a bug, include configure.log
in your bug report.
A.6.4. Compilation problems
Please include these files:
config.hconfig.mak
A.6.5. Playback problems
Please include the output of MPlayer at verbosity
level 1, but remember to
not truncate the output when
you paste it into your mail. The developers need all of the messages to properly
diagnose a problem. You can direct the output into a file like this:
mplayer -v options filename > mplayer.log 2>&1
If your problem is specific to one or more files,
then please upload the offender(s) to:
ftp://upload.mplayerhq.hu/MPlayer/incoming/
Also upload a small text file having the same base name as your file with a .txt
extension. Describe the problem you are having with the particular file there
and include your email address as well as the output of
MPlayer at verbosity level 1.
Usually the first 1-5 MB of a file are enough to reproduce
the problem, but to be sure we ask you to:
dd if=yourfile of=smallfile bs=1024k count=5
It will take the first five megabytes of
'your-file' and write it to
'small-file'. Then try again on
this small file and if the bug still shows up your sample is sufficient for us.
Please do not ever send such files via mail!
Upload it, and send only the path/filename of the file on the FTP-server. If the
file is accessible on the net, then sending the
exact URL is sufficient.
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
A.6.6.2. How to extract meaningful information from a core dump
Create the following command file:
bt
disass $pc-32 $pc+32
info all-registers
Then simply execute this command:
gdb mplayer --core=core -batch --command=command_file > mplayer.bug
