[Libav-user] "Segmentation fault" When encoding H264 video frame

if your distro doesn't offer ffmpeg with debug symbols, I suggest 
building ffmpeg with debug symbols enabled. then link your code with it. 
If you then run your app in gdb, the backtrace (type in 'bt' and hit 
enter after the SIGSEGV is emitted) and may contain the line of code in 
ffmpeg that yielded the segfault. with this, you might be able to find 
the root cause of this problem.

out of curiosity: what distro do you use, that has problems with 
valgrind?! I never heard something along those lines.

Best,
Peter
