FFMPEG Support on OS X

Compiling or Editing the Panda Source

I compiling and using the CVS version of Panda3D, on an Intel Macs, quite succesfully. I’m trying to compile FFMPEG suuport. I’ve got the Config.pp file setup ok - ppremake works - but I get a stop in grutil:

FFMPEG was installed via DarwinPorts and is Version 0.4.9-pre1,

any ideas?

Does ffmpeg require some special compiler options to build on OSX? It sure does seem like something’s not quite vanilla about that avformat.h header file.

You might need to ask this one of the ffmpeg team.

I’m getting the same on Gentoo:

What version do you compile against?

I don’t actually know. You can check out the downloadable “thirdparty” tools and see what version of ffmpeg is in there.

unfortunately, the original ffmpeg implementation was built on the cvs head, which is horribly outdated from the svn head. I’ve had success getting the svn version to compile in osx, so we should be able to get it working in the near future.
