[FFmpeg-user] Error compiling FFmpeg source from the GPAC project's 'gpac_extra_libs' archive

[Jonathan Busby]

Hello. I've been trying to compile the version of FFmpeg that is
provided as part of the GPAC project's 'gpac_extra_libs' archive.
This is an archive of libraries required to compile GPAC, of which it
includes FFmpeg. The problem is, when I run './configure
--disable-debug; make'
I get the following errors :

'
In file included from allformats.c:21:
avformat.h:256: warning: ‘AVFrac’ is deprecated
allformats.c: In function ‘av_register_all’:
allformats.c:134: error: ‘rtp_muxer’ undeclared (first use in this function)
allformats.c:134: error: (Each undeclared identifier is reported only once

allformats.c:135: error: ‘rtsp_demuxer’ undeclared (first use in this

make: *** [lib] Error 2

Any help or insight into what might be causing above would be greatly
appreciated.

Thanks,
