r19875 is the last working version, the next revision that I'm able  
to compile is r19878, and it's broken.

Author: lucabe
Date: Sun Sep 17 17:02:13 2006
New Revision: 19876

Modified:
    trunk/libmpcodecs/vf_sab.c
    trunk/libmpcodecs/vf_scale.c
    trunk/libmpcodecs/vf_smartblur.c
    trunk/spudec.c

Log:
Use PIX_FMT_* instead of IMGFMT_* when calling sws_getContext()


Hope that helps.
