[osg-users] [build] Disable FFMpeg while building OSG?

[Pei JIA]

Hi,

Trying to build OSG from source, under Ubuntu 16.04.1, with GCC/G++ 5.4.0. It seems there is NO Option for FFMPEG (Enable or NOT), but it automatically look for FFMPEG related directories by default, and found the following:



Code:
                                                                                                                         
 FFMPEG_LIBAVCODEC_INCLUDE_DIRS   /usr/local/include                                                                                                                                    
 FFMPEG_LIBAVCODEC_LIBRARIES      /usr/local/lib/libavcodec.so                                                                                                                          
 FFMPEG_LIBAVDEVICE_INCLUDE_DIR   /usr/local/include

 FFMPEG_LIBSWSCALE_INCLUDE_DIRS   /usr/local/include                                                                                                                                    
 FFMPEG_LIBSWSCALE_LIBRARIES      /usr/local/lib/libswscale.so 



And, what I got later on is the following ERROR messages:

So, my questions:

 Is there a way to DISABLE FFMPEG while building OSG?


 if FFMPEG MUST be ENABLED by default, any way to make current OSG compatible with current FFMPEG release 3.2.2 ?



Thank you!

Cheers,
Pei
