I am new to ffmpeg. Compiling/using it for only 2 days.

So I do not know all the implementation details of all the codec.

The table is used in the mpegvideo encoder and the eatgq decoder. For  
--disable-encoders or --disable-decoders to work, this table should  
not be in a coder or decoder file.

As it was originally in the mpegvideo_enc.c file I thought that it  
make sense to move it to mpegvideo.c, if it is a bad idea what would  
you propose to make --disable-encoders or --disable-decoders to work ?

I could move it to any file you suggest and submit a patch with this  

Thanks in advance.
