[MPlayer-dev-eng] Compilation of MPlayer broken in libavformat/vapoursynth.c

[Erik Auerswald]

Hi,

currently MPlayer does not compile on my system, compilation breaks with

------------8<--------------
CC      libavformat/vapoursynth.o
libavformat/vapoursynth.c:28:25: fatal error: VapourSynth.h: No such file or directory
 #include <VapourSynth.h>
                         ^
compilation terminated.
make[1]: *** [libavformat/vapoursynth.o] Error 1
------------8<--------------

Root cause is that this ffmpeg feature is not tested for in MPlayer's
configure. Filtering out the VapourSynth demuxer in MPlayer's configure
suffices to build MPlayer [for me].

$ svn diff configure

Please note that ffmepg's configure sets two #defines after detecting that
VapourSynth is not available:

#define CONFIG_VAPOURSYNTH 0
#define CONFIG_VAPOURSYNTH_DEMUXER 0

But MPlayer's configure with the above patch sets just the second define:

#define CONFIG_VAPOURSYNTH_DEMUXER 0

Thanks,
Erik
