The ffmpeg is now checked into svn/trunk, but it's still very much in development. Currently it reads video streams but no audio. Consider it bleeding edge development. I'm pretty optimistic about the prospects, ffmpeg is a bit of an odd beast in terms of the way the project is managed + distributed, but it is very portable and supports a wide range of formats and looks to be much cleaner to work with than either xine-lib or Quicktime. My hope is that we'll be able to standardise of the ffmpeg plugin and deprecate the previous Quicktime and xine-lib plugins, but first will need to get it up to feature equality with these plugins. To achieve feature equality we'll need to make sure that we have audio and live video stream support in place, and make sure that we can build across all the main platforms. Audio should be supported this week, then hopefully we'll be able to add live not long after.

Re: [osg-users] Loading movie
HI Thomas, Thanks for the posting your FFmpeg code. FYI, I've had feedback from a windows users that FFmpeg turned out to be perform better than using DirectShow, so a good FFmpeg plugin might still add value under Windows. As for the non power of two issue, this is easy to solve at the scene graph end, simply attach the ImageStream to a TextureRectangle or a Texture2D with the setResizeNonPowerOfTwoHint(false) (this only works with hardware/drivers that support NPOT textures, but that's most modern hardware these days).

That's why it's always worth doing a syncronization step before coding :-) I've just got the green light from my boss. Excellent news. Means we all save some time, and we all can work on improving the code base. I suggest you use Tanguy's implementation. I'd help where I can. Our code is not a plugin in the OSG sense, but is part of a framework for doing image processing with OSG. I'm trying to get the whole framework released. There might be some existing parts of the framework we can later include, e.g. movie writing. jp -- This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.

I've done some research into the whole FFmpeg GPL vs LGPL issues, since I would like to release our code under LGPL. It is quite easy to build LGPL versions of ffmpeg on Debian/Ubuntu. The standard packages contain GPL code. If you would like to know the gory details, let me know. jp -- This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.

Re: [osg-users] Loading movie
ok, but what I have to do to change xine by ffmpeg for example ? I have to write other plugin ? On Tue, Jan 13, 2009 at 9:34 AM, Robert Osfield robert.osfi...@gmail.comwrote: Hi Carlos, From your description this does sound like a threading issue with xinelib. xinelib wasn't really designed for how we use it, rather it's a lib designed for writing conventional movies players, and to get video support under Linux I had to fit this square peg through a round hole. When I wrote this plugin a few years back I looked at various alternatives but none were mature enough/amenable enough to be squished through our usage requirements, xinelib ended up being the best of bad lot. Things under Linux haven't stood still, gstreamer is probably viable now, and J.P mentions about a ffmpeg plugin that actually been developed and might even be open source soon. My guess is that now both gstreamer and ffmpeg are probably better routes for video support under Linux. Robert.

Re: [osg-users] Loading movie
Dear Carlos, from my experiments some time ago (osg 2.4, ubuntu 7.10), playing _multiple_ movies through ImageStream instances using the osgdb xine plugin result in sporadic crashes and funny playback/pause behavior, most probably caused by threading issues. At the time I did not have the time to go into the problem too deeply, but I recall I found it suspicious that only a single xine player instance was responsible for handling multiple movies. Again, crashes might also have been caused by some video codec used inside xine. What type of movie (container, codec, sound, size etc.) are you trying to play? regards, Gerwin ps. I was hoping for some public ffmpeg plugin implementation to pop up on the list, but either I missed it or it's not yet been released.
