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?
