[FFmpeg-cvslog] r15002 - in trunk/libavformat: internal.h sdp.c utils.c

[rbultje]

Author: rbultje
Date: Thu Aug 28 01:43:28 2008
New Revision: 15002

Log:
Export data_to_hex() as private API in lavf, rename to ff_data_to_hex() and
move it from sdp.c into utils.c. Also add new header internal.h specifically
for lavf-specific internal API. See discussion in "Realmedia patch" thread
on mailinglist.
