I'm using mplayer (a somewhat old version) to play a raw YUV 1920x1080 (progressive) experimental sequence. The command line is: mplayer -rawvideo on:w=1920:h=1080:fps=60 toys_and_calendar.yuv It plays just fine (actually, too slow, but that's an I/O issue) except that the displayed aspect ratio has been changed: it's too narrow so things look tall and skinny. If this is a (fixed?) bug please let me know. Seems I've read something about aspect ratio changes with 1920x1080 material but I can't find it either on the net or in the docs. I've tried fooling around with `-aspect' and `-vop scale' to no avail. I would love to know what "aspect: Warning: no suitable new res found!" means Is it because the displayed sequence is too big for my screen? How to overcome this? Any help will be most appreciated. Here is the output: (Yes I know the Mplayer version is old. I must find time to build the newest CVS.)
