almost similar to a recent post of Helena, I have problems compiling cvs

As far as I can tell ffmpeg is installed correctly (mpeg1video_encoder
is defined in config.h, no errors) ... any tip?
It should be declared in avcodec.h:
extern AVCodec mpeg1video_encoder;
I checked out ffmpeg svn and in avcodec.h there is just
extern AVCodec *first_avcodec;
I don't have a config.h in the ffmpeg include directory, and
gsd_image_ppm.c doesn't #include it (in fact, if it did have
"#include <config.h>", there's no guarantee that it would be ffmpeg's
config.h which was included; config.h is a rather common name).
It appears that your version of ffmpeg isn't compatible with the OGSF
library; I can only suggest removing --with-ffmpeg from your configure
command.
After removing --with-ffmpeg compilation is fine.
I'm not really satisfied with that solution, but at the moment it seems
I have to live with it and move on.
Thanks!
Volker
