[FFmpeg-devel] [PATCH 11/12] avformat/rtsp: #if unused functions away, fix -O0 compilation

[Andreas Rheinhardt <andreas.rheinhardt@outlook.com>]

parse_rtsp_message() is only called if the rtsp demuxer is enabled
and so it is normally compiled away if said demuxer is disabled.
Yet this does not happen when compiling with -O0 and this leads
to a linking failure because parse_rtsp_message() calls functions
that may not be available if the rtsp demuxer is disabled.
Fix this by properly #if'ing the unused functions away.
