I'm writing an application that uses libswscale, and I can't get its error
messages. I call sws_scale, it fails and I have no cue where to look for the

This error only occurs in Linux (Ubuntu 8.04) in Windows build (Mingw32) it
works fine. I'm suspecting I'm passing some wrong parameters, but it's kinda
hard do debug on Linux  (Need to look for a good IDE).

I've looked av_log code, tracked it, written a callback, but I cannot make
the damn error message show on console, terminal nor text file.

Any help would be appreciated.
