Aegisub crashing out with "Vector too long" error #83

Closed magnilens closed 10 months ago

magnilens commented 11 months ago

Aegisub version: Feature release 10

When I try to open this video in Aegisub, it just dies with that "vector too long" messagebox. It's just a black rectangle for 24 frames. I cut it out from a longer video that played fine on its own. I also tried stitching several copies of this video together to see if a longer one was playable, it wasn't. Same error.

Sample

I can't reproduce this with your file, it loads fine for all normal video providers. What OS and what Audio/Video providers are you using?

magnilens commented 11 months ago

I'm using windows 10 and FFMPEGSource as the audio and video provider, according to aegisub's advanced preferences window, anyway.

Did you try open video drag n drop or via menu?

magnilens commented 11 months ago

It was both drag n drop and right click menu on Explorer. However, opening the video through Aegisub's menu had no problems. I had some other 1 second videos I made to be used as thumbnails. They also encountered problems if I used drag and drop or right click menu to open them in Aegisub. But also no problems when using the menu instead.

At least I know there isn't a problem with the video files now.

@magnilens your videos have audio tracks? It seems to me that this bug appears when there is no audio track in video file.

magnilens commented 11 months ago

You're right! I just tested with a few video files with and without their audio tracks. Those without audio tracks will cause this bug when dropped into Aegisub or if opened via "Open With" in Explorer. Opening the same files via Aegusib's open video menu caused no problems.

So #61 is same bug

@arch1t3cht, more info about the bug

arch1t3cht commented 10 months ago

I found the issue now, as well as the reason why I couldn't reproduce it before (though I still can't reproduce Aegisub crashing entirely. I just get the error message but it keeps running.). The default value for the audio provider is ffmpegsource (mind the lowercase), while the provider's name is FFmpegSource. This trips up the provider selection. As soon as you change the default audio provider setting within Aegisub once, the issue disappears.

Still, I'll fix some stuff to make this less likely to happen.
