Hi everybody,
i'm wondering if is it possible to use ffmpeg plugin with OSG 3.0.1, to play a
video frame by frame.
I compiled osg 3.0.1 with ffmpeg plugin, and i run the osgmovie example with
no problem.
Now, what i'd like to do, is to play a video frame by frame : i would say to my

I think I found a little issue with ffmepg plugin. According the source
files Xine plugin supports .ogv extension (only) and ffmpeg plugin
supports .ogg (only).
It seems that .ogv is now official extension for video.:

Hi Ari,
Just add the supportsExtension(ogv,Theora movie format); into the
ReaderWriterFFmpeg.cpp and see if that works fine for you. If it
does then send the change to osg-submissions ;-)

Good to here you've got things working. Still don't know what might have

Our plugin doesn't contain any inflateInit_ or inflate method of any kind,
so the missing sybmol must be coming from ffmpeg itself. I haven't see this

What happens when you run:

I suspect that you are still hitting against the plugin not loading

this function is from zlib

HI Carlos,
As I don't see any of these problems, I'm afraid there isn't much I can do
apart from make suggestions for you to try out. Right now it looks like
you'll need to add the zlib library into the build of other ffmpeg or our
plugin.

You have to donwload ffmpeg and build the plugin by setting up the right
