[Linphone-users] compiling errors with mediastreamer2

[류호은]

 I'm trying to compile mediastreamer2 but I have a problem with ffmpeg.

I ran configure script, and make.

Following errors ocurred.

videoenc.c: In function 'prepare':
##videoenc.c:190: error: 'struct AVCodecContext' has no member named 'time_base'
##videoenc.c:191: error: 'struct AVCodecContext' has no member named 'time_base'

videoenc.c:381: warning: dereferencing type-punned pointer will break strict-aliasing rules
##videoenc.c:384: error: 'AV_NOPTS_VALUE' undeclared (first use in this function)

I installed libavcodec(also avformat)-devel packages.

what should I do?

thank you.
