has anyone seen m4p (mpeg4) files playing back oddly in livecode
players on the mac with a white frame at the end of the file? cant see
the white frame in qtplayer or any other player and is not there in
the original uncompressed qt file out of the editor, but in lc im
getting this white frame at the very end when i create m4ps from
handbrake. if i use compressor or qt to make movs (all h264) they
behave fine, but handbrake h264 m4ps give this odd white frame. im
guessing its something of the m4p not having the full mov wrapper and
thus not behaving perfectly in lc.
you can get rid of it by backing off the play to end a few frames
before the end of the file, but unfortunately the editor did not
listen and leave a good second of black at the end of each piece (as i
always request) so doing this leaves a ghost on the screen.
Im back at the monterey bay aquarium doing an update on the auditorium
program here thats been run by lc/rev/metacard for like 15 years now!
we started doing traveling systems of the whole thing on macbooks a
few years back. basically the presenters interface runs on the macbook
screen and lc pumps 720p out the external port. im replacing the
training system (which uses an mpeg server) with a mac mini now as
well to show 720p and testing if the top end macbook pro could push
1080p out! amazing to turn a mac into such a video server. lc has been
really robust in doing this and not been able to kill it yet by
torturing it!
cheers
