Hi
I am using FFmpeg 0.6 version for ppc.
I get the following when I run using valgrind.I would apprieciate any help.

Why everybody use endless configure parameters? Just "./configure" does
not work for you?
Isn't it immeterial to the issue being reported.BTW i need to include only the
formats I need to make the size of the library and my application be as minimum
.
On the parameter it is important for me to know will help
--enable-memalign-hack or how does it work.
I don't think anything you might add to configure (including
--enable-memalign-hack) will change this invalid read, but I cannot be
sure without understanding the problem. Also, what is the point of
messing around with the cflags? You don't trust the FFmpeg developers to
know which flags works better with their own code? Also, are you
_really_ cross-compiling?

will using --enable-memalign-hack help?
Can you please tell me if this problem happens when decoding any file or
just a particular one? Can you also show the full command line you used
and the full output of ffmpeg?
I am not yet decoding but only trying to get the parameters using
av_find_stream_info.I am not using ffmpeg binary but using myy own application
which opens using av_open_input_stream and extracts the stream info.
Can you test if you can reproduce this problem with the ffmpeg binary?
This helps a lot to know what is happening.
HERE IS THE OUTPUT FROM FFMPEG BINARY
Thank you, that looks like something we could reproduce.
