Hi, I think this is not possible with the current avfoundation-plugin. If you reord a video in portrait mode, then the video-size is still 960 x 460. The ios stores the transformation of the video into as a video-property (called prefferedTransform).
This transform is used when playing back the video on ios-devices or with QTKit / Quicktime. The QTKit-pipeline can handle transforms when decoding video (you'll get a 460x960 image stream), the avfoundation AFAIK not, With avfoundation you'll get the raw pixels. Performancewise this makes sense especially for mobile devices. Do the decoding a fast as possible ond the cpu and do the transform in the UI with OpenGL ES. A workaround could be to convert the preferredTransform to an osg::Matrix and attach that as an UserData to the image-stream, so you can get the matrix from the imagestream and use it to transform your textured node/geometry. But currently i am too busy to implement this. cheers, Stephan Am 09.01.13 18:29, schrieb Alessandro Terenzi: > Hi again, > I managed to use the avfoundation plugin, everything seems to work fine but I > have an issue with a video that was recorded using an iPhone (portrait mode): > when it is played on a texture, it is rotated by 90 degrees.
