problems with Quicktime/Video
« on: Feb 4th, 2004, 9:11pm » |

Hi,
I'm a processing newbie so I'm sorry if this is a dumb problem. I'm interested in working with video in processing so starting simple, I opened the "loading_quicktime" example. When I try to run it, the sketch window doesn't open and Processing freezes up ("not responding"), requiring an "end task" from the windows Task Manager.
I'm running Processing 0067 on Windows XP Pro with Java 1.4.2_03. Quicktime 6.5 (with Quicktime for Java) is properly installed and QTJava.zip is in the \system32\ directory. I also installed WinVDIG, but I was pretty sure that was just for using cameras. Can anyone tell me what the problem might be? Thanks a lot.
-Aaron

interesting. well just for the sake of experimentation, i plugged in my firewire camcorder and the camera example works fine. so thats cool.
however, still no luck with the "pixels" or "loading_quicktime" video examples.

You know aadigi, i never thought to test "pixels" or the others because I use my mac for video stuff. But your right...
they don't work.. it would be good to fix this..
well spotted!

I seem to be having the exact problem, Processing freezing when loading and playing quicktime ( 0068 ). It's fine if when using just loadVideo(), but as soon either play() or repeat() is added it hangs.
Since I'm not using a webcam, just loading a quicktime, those replies don't really help.. Did you guys find any solution?
thanks..

This is a very old problem that hasn't been fixed, and no one has really given a straight answer as far as to why this affects some people and not others. Apparently, it is something funny in QT.
I am one of those who can't open QT movies, but can capture live video from QT. As you, I use WinXP and the latest QT version. However, the problem shows with all of the QT versions I've tried. In addition, it shows on my 2 other winXP machines, all with QT6.
Fry, or anyone in the Dev team, can we know what the status of this bug is? is it ever going to get fixed? is there something we can do to get QT movies into P5 (getting some other version of QTJava?)? why can some play movies and some can't? please, please, please, some info on this would be great, I REALLY want to work with non realtime, or non-input, video.
thanks

the lack of straight answer is more to do with not having time to work on it than me hiding anything--i'm a person, not a corporation.
as i've heard, qtjava, irrespective of processing, seems to be fairly buggy. so i'm not sure whether the problem lies in the video code from hernando (who wrote the video api) or if it's apple's fault. it's equally likely to be either.
obviously we'd like to get this fixed, but as for a clearer answer, it will be at least may before the issue is addressed, and probably later, since it's further down the todo list than other things. the section on 'video' in the todo list is long, as you've seen the many comments about video problems here on the board.
in the meantime, you're always welcome to hack around with quicktime for java directly, without p5's video library; or use something like java media framework.

Not what I meant whatsoever Fry, please don't take it like that. I know that we are all very grateful for a most excellent piece of software you guys have created. If you are reading frustration, well, you are partly to blame, since you have produced such a high quality product that our expectations are sky high and we lose sight of the labor of love P5 actually is 
Anyway, I'll follow your suggestion and hack away at QTJava. Obviously I'll report any successes (hopefully!) back to the board.

hi there
try this (i dont think its a qt problem):
http://webcamxtra.sourceforge.net/
you will find the WinVDIG_099.exe in the .zip.file.
after having installed this, for the first time
my camera was working without that alt+strg+entf-thing.

i seem to have the same problem as you guys with the freezing p5.
my first assumption was, that the .mov was not found. so i removed repeat() and image(), basically just havin a script that does a loadVideo.
interesting enough i now get a NullPointerException (see below). i strongly assume that there's something wrong with locating or opening the file. i currently use a full path (c:/Documents and Settings/.../.../.../foo.mov) because i was not sure where p5 would search for the file if referenced as 'foo.mov' only. is that what you people are getting too?
greets./

This happens because processing is installed in a path with a space in it.
Move it to e.g. c:\processing and try running one of the examples.
e.g. File->Open->examples->video->loading_quicktime.

Stephen
