I managed to get it running through gdb but it's not helping me troubleshoot 
much more:

more debugging (kind of) a list from gdb at the fault:

Ok so to me it looked like there might be an issue with the png libraries ... 
so I
compiled zlib and the latest libpng ... and got the same error:

Sorry for the late response, I was on holiday.
Can you type backtrace in gdb?

Original comment by dirk.vdb on 20 Aug 2008 at 11:44

[GoogleCodeExporter]

Absolutely :)

However in my effort to trouble shoot I started compiling everything from 
scratch ...
and now I can't get ffmpegthumbnailer to build. If I can get it building again 
I will
post my backtrace.

for right now I'm fighting with this:

/bin/sh ../../libtool --tag=CXX   --mode=link g++  -I/sw/include -version-info 
2:0:0
 -o libffmpegthumbnailer.la -rpath /sw/lib moviedecoder.lo pngwriter.lo jpegwriter.lo

ld warning: codegen in _av_aes_init (offset 0x00000148) prevents image from

There's thousands of lines of this followed by:

ld warning: codegen in _yuv420_rgb15_MMX2 (offset 0x00000228) prevents image 
from
loading in dyld shared cache
ld: absolute addressing (perhaps -mdynamic-no-pic) used in _av_aes_init from

'-read_only_relocs

collect2: ld returned 1 exit status
make[2]: *** [libffmpegthumbnailer.la] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all-recursive] Error 1

I'll see what I can figure out
