If you mean buffered, through standard stdio routines, than yes, that probably helped. But in the end "abysmal performance" in writing on and/or reading from a pipe would have been an issue here too because at some point the code (or the user) would be waiting for the ffmpeg result ... And I cannot recall having noticed a significant difference in processing speed between OS X and MS Windows. (And I should add that I either ran XP in a VM on the same OS X host. The same code under Win7 on a netbook was of course considerably slower ;)) R. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
