I think I found a heap corruption with x265 - but I’m not sure how I should be reporting it, whether just in here normally or some other way - please let me know how I should report it and I will do it within a few days. The scenario is basically: I have an mp4 file (I actually have 2 cases that I get this with, but presumably they are the same, but I can share both) & when re-encoding with libx265 in ffmpeg it exits with a STATUS_HEAP_CORRUPTION - it only does this when using libx265 as the encoder, and not with e.g., libx264 as the encoder (I haven’t tested others), so I am assuming that it is likely caused by x265 as it seems to be running x265 encoding when it crashes.
I reproduced this with the latest version of this repo on Windows, and have not tested it with a new enough version on other OSes. I haven’t tried debugging it or anything like that, so I can only guess that it is caused by x265, but I assume you guys are much better at debugging this kind of thing that I would be 😅
Anyway, let me know the best way for me to share the repro file / case, and then I will do so 🙂
