Downloaded and ran wonderland.jar (2009-11-13)

I tried to drag and drop a .flv file into wonderland.

The "Launch Failed" error message reads: "Unable to launch Cell that supports wlcontent://users/Mike/movie.flv

should this work? Thanks - Mike

I dumped 64bit as I didn't see any huge gains with it and some pain. I'd
rather see 32bit worked on to 0.4 functionality levels and then go for
64bit. BTW, I still have a non-responsive client. Ric

Wonderland doesn't currently support in-world video playback. When we release this feature, you should be able to drag and drop video files into the client to initiate playback.

I'm confused. In the demo video "Matt" clicks on posters mounted on the wall which are hyperlinks to video which then plays on the screen. Is this supported?

See iSocial - University of Missouri (Four posters that are hyperlinks, clicking plays video on the wall)

In another room Matt clicks on a poster for Wall-E to play the trailer on the screen.

Those are demos of Wonderland 0.4 which did support video. We're still working on video for 0.5.

The reason for the delay is that 64-bit systems are now more prevalent than they were in 0.4, so we have to build 64-bit versions of the codec libraries, which is a bit harder than we'd anticipated due to some legacy third party code.

Sorry for the confusion.

I understand. Thanks for the info. I'm really only interested in creating a demo at this point and for that it sounds like I should really use 0.4. Probably things will be further along in 0.5 by the time I'm ready to do a real project.

Mike,

I highly recommend that you start using 0.5 for your demo, not 0.4. Web cam video support already works in 0.5 and recorded video will be available shortly. Most other things work much better in 0.5 than they do in 0.4, plus it will be a lot easier to help you work through problems if you're working with the new code base.

My 2 cents :-)

Can you estimate when video will be available? (a ballpark guess only, no promises of course).

I absolutely need to have video for a demo and time is short. I wasted a lot of time on Open Cobalt and OpenSim.

0.5 was rather easy to run. I wasn't successful setting up 0.4 on my first attempt but I'll give it another shot tonight. I just need working video before the end of the semester.

Thanks, Mike

Mike,

No promises, but Nigel has estimated about two more weeks. I'll say three more weeks, factoring in the US Thanksgiving holiday which will make next week a short one for us. When is the end of your semester? And can you say more about your video requirements?

Semester ends 12/23/09 but I'll see if I can run over into the spring semester.

I hope to see support for flash video (.flv). Is that a possibility? Much of my video library was created by former students and posted on the internet as .flv files. Open Cobalt only allowed mpeg files but the files sizes were really a problem. Which video formats were supported in v0.4?

I'll work on other parts of my project and get more familiar with Project Wonderland in general while I wait for v0.5 video support. I'll also try to get v0.4 running just as a backup plan.

Thanks for your help, Mike

In theory the 0.5 video player will support Flash video (.flv) files since it's based on the 0.4 video player which did support this format. Unfortunately, the devil is in the details: there might be a version mismatch between your encoded files and the one the codec supports. If you could make a sample video available for testing, I can verify whether it will work or not.

Here's the documentation for the 0.4 video player:

I'm not sure sending a sample video will help. All of the videos come from different sources. Some were made by students from other countries. Even if I sent you a sample video it wouldn't be representative of the entire library. Is there a way for me to encode (or re-encode) a (flash) video so that I know they will work in v.05?

After reading the video documentation I'm guessing that video converted with FFmpeg is recommended. Can you recommend a FFmpeg based project http://ffmpeg.org/projects.html (preferably with a gui interface) that will work on OSX or windows?

Hi

I use http://www.ffmpegx.com/ quite happily. The install is a little more complicated than usual for a Mac, but it works well.

cheers

Does it do "All to .flv" including ".flv to .flv" conversions?

Thanks, Mike

Mike

looks like it should, though I haven't tried it myself. I've only used it for avi/mpeg/h264 conversions.

As far as I know, the drag and drop video feature not works.
