[1.2.0-RC1] export (.wav and .ogg) stops after 3:54 on Win7Pro

[hedwig2013]

Each time i'm trying to export a project it stops at 3:54. The Project is over 9 minutes long. A short "sound shock" can be heard in the moment lmms stops the export.

Hi, I'm on Win7Pro on a more recent build, and I've exported longer projects, so I think it's been fixed.

But, to be sure, could you upload this project for us to test, or check if it always happens with any project?

Hi, here is a screenshot with export configurations. I can't attach the original file here cause it is copyrighted material. The file has 17 voices and uses sf2 player instrument only. The SoundFont is the GeneralUser GS 1.47 Soundfont. https://lmms.io/documentation/Useful_resources http://www.schristiancollins.com/generaluser.php I'm using automation tracks for pitch and volume. The play time is about 9:25. A second screenshot visualizes the song's structure. The bass instruments are configured with a BassBooster and the Calf Reverb LADSPA is used in the FX-Mixer.

The lmms installation is unchanged. The preferences are unchanged with the exception that i configured the default soundfont as GeneralUser GS 1.47 file.

I hope this will help you to reproduce the bug.

Thanks!

I can't attach the original file here cause it is copyrighted material.

If you can exchange it privately with a tester (such as @DeRobyJ) to confirm that the latest fixes it, that would help. If not, we would need a project file which reproduces the crash but does not violate any copyrights.

Done via mail

gmail put the mail in spam, I just read it >_>
I can reproduce. Each time I export, it will stop at a certain point, even on a more recent version.

And the problem is the time signature.
The first point that stops the export is around 1:20 rather than 3:54, and that's exactly the place where time signature changes from 4/4 to I believe 5/4.
There, export fails, and if it doesn't fail there, it will sooner or later.

Can you please create a copy of your project and remove global automation of the time signature?
The song should be exported fine.

Then, I tested the problem on a new project, and it seems there's no problem. So there's something else that makes time signature crash the export process.

#2030 ?

[liushuyu]

Well, I think this issue is identical to #2030. So mark one of them as duplicate?

[DeRobyJ]

Kinda, but I can't reproduce on a new project

[hedwig2013]

Sorry, but now it does not simply stops. Now it hangs or crashes. Even if I remove all global automations of any type. The behaviour is the same for "export" and "export tracks". I used the same file i send you previously. While "export tracks" it can export some tracks.

[DeRobyJ]

That could be because of how unstable was that build, there's no problem in my version

[hedwig2013]

Okay. So I will retest with the next RC. Thank you for your support so far.

[DeRobyJ]

Thank you for sharing the issue :)

The export loop condition contains Song::isExportDone(),which checks for the done-ness by doing math that will be wrong at some point as soon as the song contains more than one time signature, see https://github.com/LMMS/lmms/blob/master/src/core/Song.cpp#L431. It multiplies the song length in bars with the length of a bar to get a value in ticks, which obviously breaks when the time signature changes.

Maybe checking the current position against exportEndpoints.second would be wiser?

@hedwig2013 can you retest with the RC2 please?

[Umcaruje]

The op hasn't replied in more than a month and #3576 should fix this. It will be available in RC3. If this issue still exists in RC3, @hedwig2013 let us know so we reopen.

[hedwig2013]

Sorry for my late response. The bug is fixed. Everything is working fine.
