|
|
|
|
<P>Good bug reports are a very valuable contribution to the development of any
|
|
software project. But just like writing good software, good problem reports
|
|
involve some work. Please realize that most developers are extremely busy and
|
|
receive obscene amounts of email. So while your feedback is crucial in
|
|
improving <B>MPlayer</B> and very much appreciated, please understand that you
|
|
have to provide <B>all</B> of the information we request and follow the
|
|
instructions in this document closely.</P>
|
|
|
|
|
|
<H2>How to fix bugs</H2>
|
|
|
|
<P>If you feel have the necessary skills you are invited to have a go at fixing
|
|
the bug yourself. Or maybe you already did that? Please read
|
|
<A HREF="tech/patches.txt">this short document</A> to find out how to get
|
|
your code included in <B>MPlayer</B>. The people on the
|
|
<A HREF="http://mplayerhq.hu/mailman/listinfo/mplayer-dev-eng">mplayer-dev-eng</A>
|
|
mailing list will assist you if you have questions.</P>
|
|
|
|
|
|
<H2>How to report bugs</H2>
|
|
|
|
<P>First of all please try the latest CVS version of <B>MPlayer</B> as your bug
|
|
might already be fixed there. Development moves extremely fast, most problems
|
|
in official releases are reported within days or even hours, so please use
|
|
<B>only CVS</B> to report bugs. CVS instructions can be found at the bottom of
|
|
<A HREF="http://www.mplayerhq.hu/homepage/dload.html">this page</A> or in the
|
|
README. If this did not help please refer to
|
|
<A HREF="documentation.html#known_bugs">the list of known bugs</A> and the
|
|
rest of the documentation. If your problem is not known or not solvable by our
|
|
instructions, then please report the bug.</P>
|
|
|
|
<P>Please do not send bug reports privately to individual developers. This is
|
|
community work and thus there might be several people interested in it.
|
|
Sometimes other users already experienced your troubles and know how to
|
|
circumvent a problem even if it is a bug in <B>MPlayer</B> code.</P>
|
|
|
|
<P>Please describe your problem in as much detail as possible. Do a little
|
|
detective work to narrow down the circumstances under which the problem
|
|
occurs. Does the bug only show up in certain situations? Is it specific to
|
|
certain files or file types? Does it occur with only one codec or is it codec
|
|
independent? Can you reproduce it with all output drivers? The more
|
|
information you provide the better are our chances at fixing your problem.
|
|
Please do not forget to also include the valuable information requested below,
|
|
we will be unable to properly diagnose your problem otherwise.</P>
|
|
|
|
<P>An excellent and well written guide to asking questions in public forums is
|
|
<A HREF="http://www.tuxedo.org/~esr/faqs/smart-questions.html">How To Ask
|
|
Questions The Smart Way</A> by Eric S. Raymond. If you follow these guidelines
|
|
you should be safe. But please understand that we all follow the mailing lists
|
|
voluntarily in our free time. We are very busy and cannot guarantee that you
|
|
will get a solution for your problem or even an answer.</P>

|
<P>Please include the output of <B>MPlayer</B> at verbosity level 1, but
|
|
remember to <B>not truncate the output</B> 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:</P>
|
|
|
|
<P><CODE> mplayer -v [options] [filename] &> mplayer.log</CODE></P>
|
|
|
|
<P>If your problem is specific to one or more files, then please upload the
|
|
offender(s) to:</P>
|
|
|
|
<P> <A HREF="ftp://mplayerhq.hu/MPlayer/incoming/">ftp://mplayerhq.hu/MPlayer/incoming/</A></P>
|
|
|
|
<P>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 <B>MPlayer</B> 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:</P>
|
|
|
|
<P><CODE> dd if=yourfile of=smallfile bs=1024k count=5</CODE></P>
|
|
|
|
<P>It will take the first five megabytes of <STRONG>'your-file'</STRONG> and
|
|
write it to <STRONG>'small-file'</STRONG>. Then try again on this small file
|
|
and if the bug still shows up your sample is sufficient for us. Please
|
|
<STRONG>do not ever</STRONG> 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 <STRONG>exact</STRONG> URL is
|
|
sufficient.</P>
|
|
|
|
|
|
<H4>For crashes</H4>
|
|
|
|
<P>If you have a core dump of the crash continue reading the next paragraph,
|
|
otherwise skip it.</P>
|
|
|
|
|
|
<H4>How to extract meaningful information from a core dump</H4>
|
|
|
|
<P>Please create the following command file:</P>
|
|
|
|
<P><CODE>disass $eip-32 $eip+32<BR>
|
|
printf "eax=%08lX\n",$eax<BR>
|
|
printf "ebx=%08lX\n",$ebx<BR>
|
|
printf "ecx=%08lX\n",$ecx<BR>
|
|
printf "edx=%08lX\n",$edx<BR>
|
|
printf "esp=%08lX\n",$esp<BR>
|
|
printf "ebp=%08lX\n",$ebp<BR>
|
|
printf "edi=%08lX\n",$edi<BR>
|
|
printf "esi=%08lX\n",$esi</CODE></P>
|
|
|
|
<P>Then simply execute the following on your command line:</P>
|
|
|
|
<P> <CODE>gdb mplayer --core=core -batch --command=command_file > mplayer.bug</CODE></P>
|
|
|
|
|
|
<H4>How to conserve information about a reproducible crash</H4>
|
|
|
|
Recompile <B>MPlayer</B> with debugging code enabled:
|
|
|
|
<P><CODE> ./configure --enable-debug=3<BR>
|
|
make</CODE></P>
|
|
|
|
and then run <B>MPlayer</B> within gdb using:
|
|
|
|
<P><CODE> gdb mplayer</CODE></P>
|
|
|
|
You are now within gdb. Type:
|
|
|
|
<P><CODE> run -v [options-to-mplayer] filename</code></P>
|
|
|
|
and reproduce your crash. As soon as you did it, gdb will
|
|
return you to the command line prompt where you have to enter
|
|
|
|
<P><CODE> bt<BR>
|
|
disass $eip-32 $eip+32</CODE></P>
|
|
|
|
and send the complete output to us.
|
|
|
|
|
|
<H3>General note</H3>
|
|
|
|
<P>If something is quite big (logs for instance) then it is better to upload
|
|
it to the FTP server in a compressed format (gzip and bzip preferred) and
|
|
include only the path and filename in your bug report.</P>
|
|
|
|
|
|
<H2>I know what I am doing...</H2>
|
|
|
|
<P>If you created a proper bug report following the steps above and you are
|
|
confident it is a bug in <B>MPlayer</B>, not a compiler problem or broken
|
|
file, you have already read the documentation and you could not find a
|
|
solution, your sound drivers are OK, then you might want to subscribe to the
|
|
mplayer-advusers list and send your bug report there to get a better and
|
|
faster answer.<BR><BR>
|
|
Please be advised that if you post newbie questions or questions answered
|
|
in the manual there, you will be ignored or flamed instead of getting an
|
|
appropriate answer.<BR>
|
|
So do not flame us and subscribe to -advusers only if you really know
|
|
what you are doing and feel like being an advanced <B>MPlayer</B> user or
|
|
developer. If you meet these criteria it should not be difficult to find
|
|
out how to subscribe...</P>
