When writing your bug report, please include:

If you encounter a crash bug, please provide the gdb output, backtrace and disassembly using an unstripped avconv binary as follows:

gdb avconv

In gdb, type 'r' for run, along with the rest of the avconv command line:

r <rest of command line>

When gdb encounters its problem, run the following commands and copy/paste the output into your bug report:

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

For gdb versions before 7.1, you need to employ a slightly different syntax for the above disass command:

disass $pc-32 $pc+32

If gdb does not provide useful information please try to use Valgrind to trace possible memory corruption.

valgrind avconv <rest of command line>

Once you have gathered this information, you can submit a report to the Libav bug tracker. You should provide all information so that anyone can reproduce the bug.

Submitting Sample Media

The developers may ask you to provide a sample media file illustrating your problem. In this case, please follow these steps:
