openDCP crashes
« on: September 21, 2012, 04:09:39 AM »
Hi
my first post, thanks Terrence and all contributors!

I have made mxf files of my program, image, sound and subtitles, all in SMPTE
all have the same length, 135655 frames
when i hit make DCP the programm just crashes.
What can I do? Any hints what to check?
Is it too long?
thx for your time!

I'm getting consistent crashes on my 64-bit machine, always at the J2K conversion phase. Sometimes before a single tiff has been converted, other times several thousand images into the process. Always have to move my storage drive over to my standard usage machine, which is frustrating. Filed a report of sorts here: http://code.google.com/p/opendcp/issues/detail?id=43

Which OS, how much memory, do you get a stack trace. CLI or GUI version?

hi
its a win7 16GB i7 machine, avid, adobeCS, resolve running very stable.
GUI version, whats a stack trace?
seems not, as openDCP freezes.
its not because the length of the file ? (90min)

correct me if mistaken, SMPTE can make 24p ?
is this the error?

thx

And I'm Ubuntu 12.04, fully updated, on a Intel® Core™ i7-2600 CPU @ 3.40GHz × 8 with 7.7 GiB of RAM. Using GUI, as I haven't found a DCI resize CLI option anywhere.

Would love to get info on obtaining a stack trace. Also, what's the best test to determine if my free memory is behaving itself properly?

I'm experiencing a similar problem...

A 5 sec, 1998x1080, 24p, silent, animated title card created in Final Cut Pro 7, exported as a TIFF image suite. Version GUI Mac  .26 will crash when trying to convert to JP2K and version .19 will go through the process but no images are exported.
MacPro 2x2.4Ghz 6 Core Intel Xeon (mid-2012), 12Gb Ram, OSX 10.7.4.
Tried with opendcp-0.0.26-mac.x86_64 (crash),  opendcp-0.0.25-mac.x86_64.dmg (crash)
opendcp-0.0.20-mac.x86_64 (says JP2K were converted but no image found), opendcp-gui-0.19b-bin-osx (same).

The very puzzling thing is that I've been converting several animations/projects over the last few days with great results (tested at the cinema), and that things started to go wrong yesterday...

hey dont want to bother you with newbie questions, could somebode plz point me to info on :

- the cmd line version / documentation
- how to obtain a stack trace if the prog GUI crashes or just freezes


EDIT
found the CLI versions in the program installation folder, trying to get in it.
still dont know how to obtain a stack trace

Using the GUI, I made a test with a 5sec sequence without issues except:
after I hit "Create DCP" WinTaskmgr tells me that open DCP is not responding for about 10 seconds, it is only if I just wait, that the program continues by offering to choose the destination/name of the DCP.

Is it possible that the GUI just takes a looooong time for a 90min sequence, in between says "not responding", and then eventually returns to work?
waiting now for 15min, nothing happens...



thx
markus

ok, replying to myself:

the crashes (not responding-messages) seem due to the length of the sequence.
After I waited for 20minutes, openDCP continues offering to choose the destination folder.
Then again, crashes while copying the mxf-files, there is a dialog-box open called "File Copy", marked "not responding", white.
At the destination folder only the image.mxf arrives and 4 xml-files (pkl / cpl / Assettmap / Volindex)
no sound or subtitle mxf-file arrives even after waiting for another 40 minutes.
Seems that this is a real crash/freeze now.

One has to be aware of that and be very patient, even with multiple "not responding"-messages at every step in DCPcreation.
Strange enough, as my machine should have plenty of horsepower (Win7/64, 16GB Ram, [email protected],2)

Anybody had success making a long (image.mxf is 80GB) feature length DCP with openDCP ???

Markus, there are several processes that OpenDCP takes its time about. It may seem like it has crashed, but in fact it is just working. Perhaps one day a progress bar or animated "working" icon may be included in the program, but for now you just have to be patient.

Any disk activity or CPU usage at all during the hang?  If there are zero of these... that's a red flag for a crash.

Have you tried not copying your MXF's?  This is just me but I find it much simpler to initially create the MXF's directly in the final folder where the DCP is going to be packaged.

For me the constant is DCI resize. If the tiffs are already compliant, no crash.

Yes, this will be handled better in the next version of OpenDCP.

Which will be when, by the way? Just curious.

Hi,
