[FFmpeg-devel] Qualification Task-PAF Playback System

[Lily Zhang]

Dear All,

I would like to work on PAF Playback System for Qualification Task. I came
across the following errors when I compile the paf_coder provide on
http://cyxdown.free.fr/pafdec.

The png.h can't be found, and I guess it's the problem why all the struct
and functions are not declared. Any one came across the same problem?
