OBS Crashing recently pointing towards avcodec-61.dll

[Raumen]

Recently my OBS has been crashing multiples times per stream and I am not sure why or what update did it? Could have been the windows 24H2 one or the 31.0.1 OBS update I have no clue but it has never been this bad before and has worked generally fine.

This is crash in 3rd party lib (FFmpeg) that OBS uses to playback media files. It seems that OBS does not provide PDBs to get more details, so it's only my guess. Anyway, you may create copy (duplicate) of the Scene Collection and Profile in OBS, then delete media sources one by one until issue disappear (I think, better to start from .webm files, including Stinger transition).
