OK, I have to agree there. But unless ffmpeg changes their development model, keeping up with them will always be a PITA... That's one of the reasons why I created the VTKOggTheoraWriter (and, of course, the licensing/patents issues). > >> <shameless_plug>I suggest you give the included Ogg/Theora writer a >> try.</shameless_plug>. > > I'm well aware of your contribution and compile ParaView with > -DVTK_USE_OGGTHEORA_ENCODER:BOOL=ON -DVTK_USE_FFMPEG_ENCODER:BOOL=ON > ever since you announced your git fork of PV on this mailing list, so even > before ogv support has been added to the official source tree. :-) It's just > that some of my users prefer avi over ogv. > > Sven Cool. BTW, does anybody here know how to reliably encode a movie for embedding in PowerPoint slides? I once found a way to transcode with ffmpeg, but that didn't work the last time I tried (although all the .avi files I created with the supposedly correct codec choice played fine in MediaPlayer...) The only thing that worked was to open the thing in MovieMaker and export it as a PowerPoint movie from there. It's beyond me why PowerPoint can't just embed and play about any format+codec that MediaPlayer accepts when it is using the MediaPlayer components in the first place!
