Summary Whenever i try to export a video olive crashes as soon as i click export. Started happening with the previous nightly build so i updated to the 3/30/23 one and the issue persists. Returns: SIGSEGV /SEGV_MAPERR I haven't found anything else in the log that looks useful

Additional Information / Output https://youtu.be/nbr3Pno0zLA sorry for the awful audio, not sure why it's so bad

This doesn't really tell me much. Exports are fine on my end. Do you get a crash report? If it started in a recent commit, can you find the last commit that didn't crash?

Updated with video showing bug. Hopefully that helps some

Can you share the crash report you're getting?

how do i do that?

on another note. i managed to get that video to export, seemed to be something to do with my timeline settings? now i have another video that says it renders ~22-27 seconds of video then quits counting. the only way to exit the exporting dialogue is to click the x button, which crashes the program.

[itsmattkc]

how do i do that?

In your video, there's a crash report that appears that you then click "Don't Send" on. Instead, copy and paste the contents here.

With my latest issue no crash report comes up

Are you absolutely sure it doesn't finish exporting if you were to leave it without cancelling?

i mean, i left it alone for a half hr

[EstebanFPV]

[itsmattkc]

When is this? Is this during export?

[EstebanFPV]

When is this? Is this during export?

Yes, i opened olive, tried to export, and then force closed it when it quit at around 26 seconds

[itsmattkc]

There's some kind of issue happening with one of the footage files you're using. It's trying to read the audio and encountering an error, so it tries again, encounters the same error, and does this infinitely, hence why the export hangs. Ideally it would cancel the export the first time it hits this error, but I've never encountered a file that does this, so it's never been written to handle it.

Would you be able to send this file? The log doesn't say what file exactly, but it's one with AAC audio in it.

there's a lot of video files in this project. i did have olive automatically select timeline settings i think off of a 2.7k 30 gopro file, and when i go to export it is exporting audio as AAC. if i switch the audio to mp3 the issue persists tho

[EstebanFPV]

all files are .mp4 from a phone and gopro, with a couple .mp3 music files

[itsmattkc]

It's not about exporting to AAC or Olive's sequence settings, it's about one of the files that happens to contain AAC audio. It may be slightly corrupt, which is what's tripping up FFmpeg/Olive and throwing the error.

The error in question is that channel element 2.1 is not allocated message. Maybe try scrubbing the timeline with a log/terminal side by side and see which clip/file throws that error (make sure audio scrubbing is on because it's definitely an audio error).

[EstebanFPV]

and it could be any file, not nescesarily the one at 26 seconds?

[itsmattkc]

No, the timers in the export dialog count realtime (i.e. how many real hours/minutes/seconds have elapsed), not how much of the sequence has been rendered.

[EstebanFPV]

[EstebanFPV]

didn't touch the timeline (just loaded the proj) and got all this

[itsmattkc]

Yes, it will also try to access the audio files on startup to generate the timeline waveforms, and is again encountering the same error. But it still doesn't tell us which file(s) are causing the problem.

[EstebanFPV]

found an audio track that throws the 2.1 thing, we'll see what happens without that

[EstebanFPV]

nope...

[itsmattkc]

If it's still throwing them, then there are more with that same issue.

[itsmattkc]

If you can send me one of the files that triggers that error, I can improve the way Olive handles it.

I'll make sure it's the files i think it is that's actually causing the issue quick

[EstebanFPV]

Now it just straight up crashed, i didn't even have to close it... All i did was get rid of 2 audio clips, and save

[EstebanFPV]

I scrubbed through it and couldn't find any more, though it did say "failed to pull from buffersink" quite a bit

That's not a good sign either. If you can send a file that causes this error too, that would be helpful.

[EstebanFPV]

well, that will be more difficult, quite a few files returned that error

[itsmattkc]

I only need one.

[EstebanFPV]

seems like it's mostly nested sequences for both errors

[EstebanFPV]

In the Sweet By and By - Zachariah Hickman.zip

[EstebanFPV]

there's one that threw the 2.1 error i think

[EstebanFPV]

it doesn't seem to like any of my nested sequences of gopro videos that are sped up in olive.

[itsmattkc]

It can't be this one. The error is during an AAC read and this is an MP3 file.

[EstebanFPV]

the 2.1 error went away from that part of the timeline when i removed that file :shrug:

[EstebanFPV]

i'd send you my project file and all my assets, but that would be a rather large .zip file

[itsmattkc]

Often when I can't reproduce issues on my end, I offer to remote in so I can see exactly what's happening myself and try to fix it. Would you be open to doing that? If so, I'll add you on Discord and we can go from there.

[EstebanFPV]

ok

[EstebanFPV]

i'm on linux if that makes it harder or easier. why, i really have no idea. i'm not smart enough to use it properly.
