MPEG_OPEN and friends not working
type: item
description: Hi guys, I have a mystery involving MPEG_OPEN and object graphics. Several mysteries in fact! Now the actual "render this" code works OK and I don't get any peculiar licence errors, so I am completely at a loss. In my code the line mpegid = mpeg_open=(dimensions), where dimensions is a 2-element vector, executes silently (well, "compiled DLM mpeg") but doesn't actually do anything - no idl.mpg file is created, and forcing a filename via the filename keyword causes similar silence. Putting things into the mpeg via mpeg_put,mpegid,window=oDraw,frame=iframe where oDraw is an OBJREF = <ObjHeapVar13(IDLGRWINDOW)>, doesn't work - no error is spawned yet there is no file created. mpeg_close "works" in the same way. Any clues?
