$ osgmovie --audio movie.avi.ffmpeg FFmpegImageStream::open audio failed, audio stream will be disabled: unknown audio format With the attached FFmpegDecoderAudio.cpp, audio sounds correctly. I am also attaching a modified version of FindFFmpeg.cmake that allows to set as FFMPEG_DIR the ffmpeg compiled in the source directory structure. It should not break anything as it only adds some additional search paths. " git-svn-id: http://svn.openscenegraph.org/osg/OpenSceneGraph/trunk@14654 16af8721-9629-0410-8352-f15c8da7e697

#In ffmpeg code, old version use "#include <header.h>" and newer use "#include <libname/header.h>"
|
|
#In OSG ffmpeg plugin, we used "#include <header.h>" for compatibility with old version of ffmpeg
|
|
#With the new version of FFmpeg, a file named "time.h" was added that breaks compatability with the old version of ffmpeg.
|
|
|
|
#We have to search the path which contain the header.h (usefull for old version)
|
|
#and search the path which contain the libname/header.h (usefull for new version)
|
|
|
|
#Then we need to include ${FFMPEG_libname_INCLUDE_DIRS} (in old version case, use by ffmpeg header and osg plugin code)
|
|
# (in new version case, use by ffmpeg header)
|
|
#and ${FFMPEG_libname_INCLUDE_DIRS/libname} (in new version case, use by osg plugin code)

# Macro to find header and lib directories
