Hi! As reported on http://bugs.gentoo.org/347481 the osg 2.8.3 release (and current trunk probably as well, as far as I can tell) has problems compiling against recent ffmpeg snapshots. The critical commit there is SVN revision 25652 from 2010-11-02, which is now in git:
http://git.ffmpeg.org/?p=ffmpeg.git;a=commitdiff;h=262d1c5d2206467809fd By default it introduces a preprocessor macro called SampleFormat: #define SampleFormat AVSampleFormat As a consequence, all references to SampleFormat in osg will be rewritten, even if they refer to some other C++ namespace. This leads to errors like this: error: ‘AVSampleFormat’ in class ‘osg::AudioStream’ does not name a type Luckily the commit also provides a means to avoid the definition. Simply include this line before including the av*.h from ffmpeg: #define FF_API_OLD_SAMPLE_FMT 0 I'd suggest you include this line in FFmpegHeaders.hpp: --- OpenSceneGraph-2.8.3.orig/src/osgPlugins/ffmpeg/FFmpegHeaders.hpp +++ OpenSceneGraph-2.8.3/src/osgPlugins/ffmpeg/FFmpegHeaders.hpp @@ -6,6 +6,7 @@ extern "C" { #define __STDC_CONSTANT_MACROS +#define FF_API_OLD_SAMPLE_FMT 0 #include <errno.h> // for error codes defined in avformat.h #include <stdint.h> #include <avcodec.h> You can also download this patch from the Gentoo bug report: http://bugs.gentoo.org/attachment.cgi?id=261477 Feel free to include this in the osg sources. If you want to reply to this mail, please cc a personal copy to me, as I won't follow list mails too closely.
