AFAIK there are no crop filters in Xine even for software decoding. A crop mode would not be hard to code, but you should request it on the Xine mailing list unless you are willing to do it yourself. As for an MPEG-2 stream, cropping it without fully re-encoding would be quite possible, but much harder to do. What we lack is an open source MPEG-2 compressed domain editing library. That would be a very useful piece of software for many other purposes too. There is always hope as long as you fight for it yourself ;) > And - will xine rescale the picture to 1280x720 if it is encoded > anamorphous? Softdevice does that automatically if you tell it the screen > is 16:9. Really nice. :-) Sure, Xine recognizes anamorphic picture and changes the scaling on the fly. Xine also detects the screen aspect ratio automatically from X configuration, but it can be changed manually if necessary. -- Niko Mikkil?
