Segmentation fault on m4v -> NTSC DVD or PAL DVD

[James Dietrich]

Steps to reproduce:
1). Select the m4v file as the source
2). Select DVD player for the device
3). Select NTSC DVD or PAL DVD for the preset
4). Click Add to Queue, then Save after selecting destination location and filename
5). Immediate segmentation fault

This is the output from attempting NTSC:

I tried a variety of other device/preset combinations, and so far the
two mentioned above are the only ones that cause a crash. The others
I've tried appear to be transcoding the file, although I haven't waited
for them to finish yet.

The m4v file is 333 MB, and it would take quite some time for me to upload
it, so I haven't done that. But if it would be helpful for debugging, I will take
the time to upload it somewhere. Just let me know. if you want me to do that.

I am running up-to-date Debian testing.

Let me know if you have any questions, or if there is anything else I can
do to help.

Thanks,
James Dietrich

Looks like this is definitely and upstream bug. If possible try to make a smaller sample and put it somewhere so that I can confirm the issue and send it upstream! (if the moov atom is at the front of the file you can just use dd to take e.g. the first 10 megs, if not you can use a tool like qtfaststart on it to move the moov atom to the front)

Thanks for telling me how to make a smaller sample. I used dd to take the first 10 megs, and the resulting file still played fine in smplayer. And it crashed arista in the same way as described above. Here's a link to the file: https://mybiblefirst.org/arista/sample.m4v
