Blender Version
Broken: version: 3.1.2, branch: master, commit date: 2022-03-31 17:40, hash: cc66d1020c
Worked: (newest version of Blender that worked as expected)

Short description of error
2022-04-19 22-30-40.mp4

Exact steps for others to reproduce the error
Based on default setup. I create a VSE project and add a movie(its size must be large, like film) to sequencer. Then I try to enable caching in panel and blender crashs.

Hi, thanks for the report. Crash doesn't happen here when I enable caching (tested on 3.1.2)
Check if this happens with particular video file or just any "large" file.
Do I need to perform any additional steps?

What I did is:

  • Open default "Video editing" file (File > New > Video Editing)
  • Add a large movie file (around 350mb)
  • Select sound strip and enable caching?

You should add a larger file. I test 313MB, 1.34GB and 3.91GB files, but only 3.91GB file makes blender crash.

@neXyon, as the bug seems to involve audaspace, any idea what might be happening here?

How much RAM do you have free in your system?
Caching loads the audio data uncompressed into memory and is only supposed to be used on small files, not full movies, since it consumes so much memory. E.g. if you load a 90 minute movie with 5.1 surround sound, caching alone will consume almost 12 GB of RAM. The crash site shows that the issue is probably that you don't have enough free memory when you try to load the movie with cashing.

Actually, it also crash when the usage of ram is only 42%(16GB ram). The size of the movie is 3.91GB, so I don't think the size of audio would be too much large.

I don't have a 4GB video available to test for now.
16GB ram doesn't seem to be that limited.
If it's not a RAM limitation, it deserves an investigation.
