[MPlayer-users] Hidden Symbols

[Mike Lothian]

Hi

I'm not sure which mailing list is relevent but if you compile the
latest mplayer with the latest ffmpeg, it fails

This is due to some required symbols not being exported by libswscale

libmpcodecs/vf_palette.o: In function `put_image':

This can be resolved by changing libswscale.v to have global * and
removing the local option

My question is should these symbols be exported by libswscale or
should mplayer not use them?

Cheers
