astrofox-io
Exporting to a video some time create a video of ~1s
As said in the title, there are time I can't explain why, but it goes through the whole export, but the output video is juste ~1 to 2seconds long ending abruptly.
The export process goes through all the frames. And looking at the developer console does not show any warning or error, so I'm not sure what's happening there.
I'm using it on Mac OS X (10.15.7) and it is the last version, at least the check update says so (version 1.2.0) I haven't try to build a version from the sources yet, but most of the changes has been package updates, so I doubt it would fix anything.
Not sure how to help there to give more infos
Here are the log from one export that failed:

I had the same problem on my MacBook. Once I changed the mp3 to WAV it finally kind of worked. But still it gave me 1:34 minutes instead of the full 2:44. Perhaps something to look into.
The same behavior I'm getting here too. My OS is Ubuntu 20.04 and I have tried both wav files and mp3 files. I'm using the available Astrofox-1.2.0.AppImage file
It seems it trims every audio file while exporting to mp4 :/ , The exported video file I have received is only 2 seconds. Can anyone suggest any workaround?
I'm also seeing audio files trimmed substantially. I have a 2.5m song that's resulting in files between 10-25s.
Can everyone try the latest version, 1.3.0? The rendering engine has been completely rewritten.
1.3.0? The latest release was 1.2.0. Also, I downloaded Astrofox 2 days ago and I'm having the same problem.
I tried using a brand new Astrofox installation (1.3.0 from the Astrofox website on MacOS 11.5.2) and had the exact same problem.
@supremestdoggo Can you try opening the developer tools and share what the output displays?
@supremestdoggo This line seems to show the error

Something went wrong when it tried to send frames to ffmpeg. Not sure what is going on. I tried on my macbook (MacOS 11.6) and everything ran fine. I'll keep digging but not much I can do if I can't replicate it.
I believe it is a lack of backpressure at renderProcess.push(image) in src/video/VideoRender.js . It will prematurely end the stdin write before all data has been processed at stdin; When the frames are finished rendering, it cuts short the write to stdin, as it hasn't caught up yet, and leads to the packet corruption error shown above — it's too small.
I believe the way to solve this is to have an await renderProcess.push(image), with a matching Promise for push, such that there is backpressure and the frames will advance and correspond correctly to what has been written to stdin.
