Somewhen while trying to play videos taken by Nikon (D7100) I observed that mplayer is extremely slow on them (it even complained that I have too slow processor etc. and then seemed to hang) while some other players had no problem with them. This appeared to be due to the occurence of some frames with very special properties which mplayer tried to interpret but the other players perhaps ignored them. I do not know video formats so deep and cannot say which particular property it was. The following option to mplayer overcame the problem, the videos were played smoothly (and without any visual difference): mplayer -lavdopts skiploopfilter=nonkey ... To be able to use such source videos in Cinelerra I simply preprocessed them with ffmpeg (recoding into x264 with default options) before loading into Cinelerra. _______________________________________________________________________________ Georgy Salnikov NMR Group Novosibirsk Institute of Organic Chemistry Lavrentjeva, 9, 630090 Novosibirsk, Russia Phone +7-383-3307864 Email [email protected] _______________________________________________________________________________
