jit.qt.movie read URL strange behaviour


Feb 03 2013 | 6:29 pm

Hello all,

I am trying to read a jpg image from my IP camera via network and I use jit.qt.movie + read URL. It seems the jit.qt.movie object stucks reading the same image. In other words, the IP camera changes the images but keeps the same name (image.jpg) and the qt object doesn’t load the new image. I know the topic was discussed here http://cycling74.com/forums/topic.php?id=11787 but the dispose msg in this case has no effect.

Other methods to read the video stream are useless to my purposes due to the long time delay of QT rtsp (see http://cycling74.com/forums/topic.php?id=31827 )

last thing, the only way so far is to use jit.uldl but in this case I’d have a disk read/write process I’d prefer to avoid.

admant,

I had a similar issue a couple years ago and ended up going with jit.uldl. I’m sorry I don’t remember the details, but it might have had to do with the exact type of mjpeg streaming not working with QT. I could be wrong.

Sorry I’m not actually much help…

thank you Simon, if no other solution shows up I’ll go for uldl.
Can this be considered a QT or a jitter bug? Maybe Jeremy Bernstein should read this post?

cheers

ah, the same problem happens if I use importmovie imageURL to a jit.matrix…

hm.. nope.

rtsp works. but it still comes with 3 seconds delay which is useless for my purposes.

(I use a different IP camera (intellinet NFC31/NFC31-WG))

One image at a time would be good enough. Unfortunately it cannot load it correctly.
http://camera_ip/jpg/image.jpg works with safari. it doesn’t with jit.qt.movie !

too bad. Will go for jit.uldl.

@admant : beyond the delay problems did you really get RTSP to work in jit.qt.movie ?

I’m struggling to get it working at all (in 6.1.0). Weither I’m using streams from jit.qt.broadcast via an SDP file, from a local DSS, or some public streams online that playback fine in VLC, all I get from jit.qt.movie is a "network error -1" in the dumpout.
