[Ffmpeg-devel] Problems Decoding DivX

  Before I dive in and ask my question, allow me to introduct myself.  I am
one of those crazy guys who still works with the Amiga, and I am currently
working on a project that uses libavcodec and libavformat.  I have been
working on it since March and last night I upgraded my source code to the
latest version of libavcodec and libavformat and am having problems that I
wasn't having before.

  I have some AVI files that I believe were encoded with DivX.  These files
played fine on the old source code from March (it was just a CVS snapshot)
and they also play fine on Windows Media Player and on the Amiga port of
MPlayer.  However, the new libavcodec source spews forth a screenful of
debug data and won't decode them.  Take a look at the attached file which
shows the debug output.  Does anyone have any ideas as to what is causing

  Also, on my system I have no way to run configure (Amiga OS is not UNIX
based) so I just made up my own makefiles.  Apart from WORDS_BIGENDIAN,
ARCH_POWERPC and POWERPC_MODE_32BITS, are there any really important
#defines that I should know about?  Any other traps that I might fall into?
 I can post my makefile and config.h files here if anyone would care to
take a look at them.

  One last thing, how is native Theora support?  Should it be working? 
Because that crashes when decoding the comments at the start of the file. 
It might be the Theora code or it might be my makefile;  I don't know.

  Thanks in advance for any help!
