I have been trying to make a DCP for a screening but DoM keeps closing itself with no error messages. I tried 3 times on 2 separate computers and both produced the same error. I do not have the logs for the first computer but I have for the one I'm using right now. On both ocasions, I downloaded the file from the same place. It appears to be only this file that causes this problem, because the 1st computer made DCP's just fine after the error and both computers made fully functional DCPs a day before this happened.
This error produces a way smaller video file than what it is supposed to be and there are no audio file/others .xml files in the DCP's folder.
I am now reencoding the file to a different coded (from h.264 to h.265) on shutter encode to see if maybe that solves the problem.
The screening is tomorrow morning, so I'll probably have to display it on VLC/MPC but I would like to know what happened and why so I can prevent/solve next time.
Also, the mp4 runs just fine on my end. I haven't been able to watch it fully but skipping around the file on a player did not cause it to crash and DCP-o-Matic seems to process it just fine when I load it into the program.
Thank you in advance.

Re: DoM suddenly closing when making a DCP.
Hi, there are a lot of decoding errors in that log, so I think re-encoding it is a good thing to try. However, DCP-o-matic should not crash / suddenly close... is it possible for me to get hold of the original "bad" mp4 file?

Re: DoM suddenly closing when making a DCP.
Hey, thanks for reaching out!
Turns out re-encoding didn't work in the end! I tried to re-encode it with shutter encode like I said but for some reason it stops at 21:41 mark. Converting on DaVinci produces the same error but at the 07:53 mark. Coincidentally, in the original file, on both timecodes the video glitches out for a few seconds before going back to normal. We just ended up playing it on VLC haha
Since was a external screening with things like authorization/approval from directors and distributors and this was one of the films that had to get authorized I sadly can't share it. But if I run into this problem with another video I can share I'll do it! I just think the copy they gave us had some kind of encoding glitch that VLC could probably ignore and play it smoothly while the other softwares didn't know what to do with it.
Thanks for answering!

Re: DoM suddenly closing when making a DCP.
It is usually easier for a player to simply skip invalid data than for an encoder to make sense of it. It may have been possible to transode the file using VLC player (watch a VLC transcoding tutorial on YouToube), as, to my knowledge, VLC uses part of the playbackengine to transcode. However, you don't know what the transcoded video will look like around the parts that were corrupt.
