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_LIBAVDEVICE_LIBRARIES /usr/local/lib/libavdevice.so
FFMPEG_LIBAVFORMAT_INCLUDE_DIR /usr/local/include
FFMPEG_LIBAVFORMAT_LIBRARIES /usr/local/lib/libavformat.so
FFMPEG_LIBAVUTIL_INCLUDE_DIRS /usr/local/include
FFMPEG_LIBAVUTIL_LIBRARIES /usr/local/lib/libavutil.so
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:
Code:

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
