Curious the svn version of ffmpeg has img_convert built in, but not
declared in any way in the headers, so to get it to work I had to add
a:
extern "C"
{
int img_convert(AVPicture *dst, int dst_pix_fmt, const AVPicture *src,
int src_pix_fmt, int src_width, int src_height);
};
To our src/osgPlugins/ffmpeg/FFmpegDecoderVideo.cpp file. This got
things building on later svn rev's of ffmpeg. You build of ffmpeg
seems to be different in some way. You could try #if defing out the
above and see what happens.
Robert.
